Are Geothermal Heat Pumps Far Superior?

What Makes Geothermal Energy a Better Choice in heating?

Cost Effective

A geothermal heat pump system will set you back about $2,500 per ton of capacity, or about $7,500 for a 3-ton unit which is a typical home size.

If you were to by an A/C or other systems you would be out of pocket in the $4,000 range.

So you have less up front costs, but on a retrofitted, geothermal HVAC unit you will have much lower utility bills, allowing you to recouped your cost in 2-10 years depending on the area you live in. You might even be able to recoup some of your cost by checking with our local utility companies to see if they offer rebate programs on high efficiency geothermal systems.You will save up to 70% on your home or office energy bills.

Durability

Geothermal heat pumps are made to withstand the elements, and the warranties can extend out over 20 years for some parts.On average Geothermal heat pumps require less up keep.

Year-Round Comfort

A Geothermal heat pump works the same as heating and cooling HVAC’s. However it is a silent system that keeps you comfortable in all seasons, and can improve humidity control in your home environment without needing a humidifier.

Quiet Operation

Geothermal heat pumps use no outside condensing units, and without hot or cold air being blown in there are no load fans to contend with. 

Geothermal Heat Pumps Far Superior

Few people are even aware that geothermal heat pumps are even an option when it comes to their heating and cooling needs. Most of us are aware that electric heat pumps are available but the new generation of geothermal units are just now gaining popularity. These state-of-the-art heat pumps provide the same continuous and even heat or cooling just like the electric pumps but they are far more efficient at doing so. So, if you are in need of a new heating/cooling system for you home or business, here are some reasons to consider purchasing a geothermal heat pump.

Let’s face itthe environment is becoming a bigger and bigger issue for everyone. We are all looking for ways to use less energy and pollute less. Geothermal heat pumps are simply the most environmentally friendly heating and cooling units available today. Plus, no system can rival a geothermal heat pump when it comes to energy efficiency or cost effectiveness. So, not only are these heat pumps environmentally friendly, they ultimately cost less to operate and consume less energy while doing so.

However, it is also very true that geothermal heat pumps will cost you more to purchase and install than other options. However, depending on the location and the cost of the other heating/cooling option, geothermal heat pumps will recover those added up-front costs within 6 or 7 years. After that point has been reached, geothermal heat pumps will save you money over the other heating/cooling options each and every single year it is in use. In the long run, these new age heating and cooling units will prove to be the most cost effective option available.

Geothermal heat pumps cool your home in the summer by removing excess heat and humidity from the home. This heat is then transferred to the earth where it naturally dissipates. The process is much quieter and less obtrusive than found in conventional heat pumps.

In the winter, geothermal units heat your home by forcing fluid through pipes buried in the ground. This fluid picks up radiant heat coming from the ground. The heat absorbed by the liquid is then compressed within geothermal heat pumps in order to raise the temperature. The heat is then distributed throughout your home.

Geothermal heat pumps also offer the added advantage of providing homeowners with free or drastically reduced hot water. This savings alone can add up to hundreds, potentially thousands, of dollars during the lifetime of a geothermal heat pump.

Although geothermal heat pumps are more expensive to purchase and install, they become the less expensive heating and cooling option as time progresses. Therefore, even if you are planning to move in the next few years but need a heating/cooling system right away, geothermal heat pumps may prove to be true selling points later on down the road. So, no matter what your plans for your home, installing a geothermal heat pump will always be a wise investment and provide you many worry-free years of heating and cooling comfort.

Coolstep New Products-Walkable Roofing and Waterproof Flooring

CoolStep: a New Innovation in Walkable Roofing, Waterproof Flooring

Skyline Building Systems, a manufacturer of walkable roofing and outdoor surfaces, announces CoolStep: a new product that will reduce the surface temperature of roofing and outdoor flooring. The product is the only waterproof membrane currently on the market with a 20-year warranty and Cool Roof Rating.

Calgary, Alberta (PRWEB) June 3, 2010 –

Skyline Building Systems Inc., a manufacturer of walkable roofing and outdoor waterproof flooring, is proud to announce the arrival of its newest member, CoolStep, to the DecTec family of brands. According to Grant Lawton, Business Development Manager for DecTec Products, “CoolStep, which has been in development for the past three years, is a natural evolution of our exterior waterproof flooring and walkable roofing products. Given the recent trends in energy awareness and sustainability,” Lawton continues, “Consumers are demanding more and more from the products they incorporate into their homes, and that demand must be met by both Design Professionals and Manufacturers.”

“The primary benefit of CoolStep, is just as the name implies, it stays cool to walk on in bare feet, even under extreme, full exposure sun” says Lawton. “We have all stepped out onto a balcony or deck that has been in hot, direct sun, no matter whether it was a painted on product, paver blocks or a composite wood, only to perform the hot foot shuffle back to safety.”

Unlike typical deck products, the color and composition properties of CoolStep actually reduce the surface temperature which is achieved by the product reflecting the sun’s rays and emitting the heat back into the sky instead of absorbing it and ultimately transferring it down to the building below.

The secondary feature of CoolStep’s reflective properties is a substantial one.

Lawton explains, “If your deck is also acting as a roof over living space, CoolStep can assist in reducing the interior temperature in the area located beneath it, thus lowering the energy consumption, and resulting cost, for air conditioning. This type of application is known as Cool Roofing.”

“Building Codes now incorporate many environmental standards and Cool Roofing is a prime example,” he adds, “The Standard is based on stringent criteria established by the Cool Roof Rating Council, (www.coolroofs.org), an independent, credible Organization which has become an essential resource for both the public, Building Product Manufacturers, and the Design and Construction Industries. We are very proud to be the first in our category to meet the criteria and have CoolStep listed as a product conforming to the requirements of the CRRC.”

Skyline has consistently been the industry innovator with their DecTec line of waterproof flooring and walkable roofing products. CoolStep, the only waterproof balcony membrane on the market with not only a Cool Roof Rating but a one-of-kind 20 Year Warranty ensures that the tradition of leading the industry continues.

About Skyline
Through our DecTec Brand of membranes, Skyline provides proven waterproofing and roofing solutions for balcony and roof-deck applications. As North America’s leading innovator in pedestrian traffic bearing membranes, our products provide a proven, low maintenance and low life-cycle cost solution with over 40 years of real-life roofing manufacturing behind each and every one of them.

Troubleshooting Heat Pumps Problems

Is your heat pump in a need for repair? Are you facing heat pump problems? If yes, then go through this article to understand the tips for troubleshooting heat pumps.

Heat Pump Problems : troubleshooting heat pumps
Heat pumps are the mechanical devices that are configured for transferring heat from one location ( source ) to another ( sink ). In the majority of the cases, heat pumps draw heat either from the atmospheric air or from under the Earth’s surface. The former type is known as air source heat pump, while the second machinery is called geothermal heat pump. Heat pumps serve for both cooling and heating the home in extreme environmental conditions.

The technology of heat pump is used in some home appliances such as heating system, freezers and air conditioners. A heat pump works by consuming a small amount of energy for transferring heat from an area with low temperature to another with a higher temperature. It is more energy efficient in comparison to heating and cooling devices like furnaces and ACs. Nevertheless like other machinery, there are certain heat pump issues, that might arise over a period. Let’s discuss in detail about troubleshooting heat pumps.

Troubleshooting Heat Pump issues

A short knowledge about the parts of a heat pump will help in a straightforward diagnosis of the heat pump Problems. The basic parts include an evaporator ( circulating fans ), reversing valve, condenser ( refrigerator coil ) and a compressor. Prior to starting with heat pump troubleshooting, turn off the power supply at the main circuit breaker. Following are just some of the common heat pump issues and methods to troubleshoot them :

No Heat Production : If there is not any heat production, then the difficulty may be due to failure in the main power supply or overloading of the motor. In order to troubleshoot this malfunction, check the power supply and thermostat and fix them ( when necessary ). In case there’s power supply, reset the motor by pressing the reset button. Also, check the ignition of the heat pump for any defects. If none of these tips work, then you can hire a professional for proper fixation.

Inadequate Heat Production : insufficient heat production is one of the major heat pump issues. In most cases, it is caused due to obstructions in the air ducts. Other reasons for this defect could be low thermostat setting and presence of dust in the air filters. You can check these systems whether or not they are working properly or not.

Low and high Head Pressure : A heat pump issue with low head pressure can be caused by a scarcity of refrigerant, damage of the compressor and soiled evaporator. On the contrary, high head pressure regularly results from overfeeding of the refrigerant and soiled condenser. Watch these systems and recheck whether the heat pumps start working normally or not.

Freezing of Heat pump : Freezing of the heat pump unit may be caused thanks to a faulty air blower or accumulation of dust and mud in the filters and evaporators. For fixing this problem, check for the defrosting option in your heat pump unit. If there is, you can defrost it and check the compressor for any defects. Do not forget to check the calibration of the thermostat.

Noisy Heat Pump : noisy functioning of the heat pumps is caused because of the reasons like loose screws, unacceptable fixation of the belts and noise from the air channels. To fix and troubleshoot this malfunction, you can tighten the screws, check the belts and introduce a plastic insulation within the metal air channels.

Your thermostat should be properly calibrated. The proper refrigerant charge will provide longer equipment life, lower your utility bills and reduce the need for air conditioning service. The benefit of a clean condenser coil is proper heat rejection, reduced run time and lower energy bills. A dirty air conditioning condenser can lead to system failure and the need for you air conditioner to be repaired. As your air conditioning system removes heat from your home, humidity is extracted from the air.

You might not know it, but something changed in 2006 that will affect the choice of products available to you when it comes time to replace your Heating, Ventilating and Air Conditioning (HVAC) equipment. That is an increase in efficiency of 30% from air conditioners that were 10 SEER, and an increase of 38% for a furnace that had an AFUE of 50%. Many of the systems available today are actually much more efficient than the government has mandated, giving you the potential of substantial savings on utility bills.

Below are some tips to keep your homes comfy and units working to their potential. They will be able to tell you very quickly whether or not you can get away with a small model when it comes to central air conditioning installation . Change the filters every 30-60 days. Rinse off the outside unit. You don’t want dirt and debris building up in the outside unit, so it’s best to clean this every few months. Use blinds and curtains where you can.

When the weather starts heating up and reaching the sweltering level, most people want nothing more than a cool place to relax and escape from the scorching heat. When thinking about purchasing a home, again especially in the warmer climes, it is a good idea to carefully examine the existing air conditioning system in the home. There are a number of different types of central air conditioning units available for homes.

Dallas and you-Let’s make it happen

Now that we’re here, can we get talking about Dallas and Dallas life? Dallas has forever been a very grand choice when it comes to relocating, building up your new dream abode and grab a cool well- paying technology job. Seeing the kind of progress that this Texas city has gone through over the last few years, to exact a number to that, let’s state the last 50 odd years, well! They have been terrific in terms of Dallas reaching zipping heights and glory with each new [daysunrise]. Financially, Dallas hasn’t been doing badly for itself. In fact, to state the facts correctly, Dallas has been on a self-promotional drive and that too, with highest committement and motivating enthusiasm. Besides Information technology and the local cuisine business, business segments on the home Improvement sides have been tapping a lot of emerging scope. Why just the city, even this this entire state has been on a Dallas-promotion trip. And the best part about all this is the fact that this idea is also doing a lot to promote job opportunities in this region. For instance, the rising potential of Dallas Plumbers in this city has been huge. In addition to this, it has also been doing a lot to provide a much-needed momentum to other housing works like Dallas Electricians work, Dallas architects, Dallas constructors and many more related fields. And in case you go with the reports that are coming in, a lot of people are now considering these as career choices. From a time when no one used to believe in all this as a bread earning possibility to a stage where people can actually smell the scope that such jobs can bring to the economy of Dallas, this city has definitely come a great distance. Now even the Dallas Roofers are keen to take out their own regulatory body that will also operate as a dais to promote the roofers industry and to even bring it in the light of Dallas guys to come up and exhibit a keen interest in this line.

Heat Pumps: What You Need To Know

 Heat Pumps: What You Need To Know

Heat Pumps

Why do most people seem so confused and bewildered about heat pumps? They have been around now for at least several decades, yet the technology behind them seems to mystify so many people. So, I decided to research this subject for myself in order to tell you how – in layman’s terms – these things work

The first thing I should deal with, I guess, is the name itself: heat pumps. Why are they called that? If they are pumps, then what are they ‘pumping?’ Well, the word pump is actually very appropriate (at least to my mind), as pumps move something – water, gas, oil – from one place (like the bottom of a well) to another place (like your sink). And that’s exactly what heat pumps do: they move, or ‘pump’ heat energy. If this is a hard concept for you to grasp, here’s an illustration. Imagine letting a cup of hot tea sit awhile to cool down. Now think about it: What really happened? Well, when a hot liquid cools, the heat energy passes from the hot liquid to the air surrounding it. In other words, heat was ‘pumped’ (moved) from one location to another.

You might not realize it, but even on the coldest day outside, the air contains some heat energy. The same is true for the ground beneath our feet: it has the capacity to store, or hold, heat energy. Heat pumps simply move, or ‘pump’ heat energy from one place to another. When you use a heat pump to heat or cool a room, you are making use of this basic fact of physics.

Let’s see this in action when you decide to cool a room: You install a heat pump, and it’s warm inside. A heat pump will circulate the air in the room, capture the heat energy that is there, and transfer that heat energy outside. Because heat energy has been taken out from the room, you will feel cooler.

What do you do in the winter? Simply reverse the whole process: use your heat pump to move heat energy from the outside to your rooms inside (even when it’s cold outside there’s heat energy there, remember?). You will feel warmer in that room as a result.

One very important not: heat pumps, by themselves, do not burn fuel to add heat to a cold room – they simply move it from someplace else. This means that a heat pump is not a furnace, which burns fuel. A heat pump is an energy-transferor, not an energy-producer.

Some heat pumps are called air-source heat pumps, so called because they use the air (surrounding the unit or from a separate unit outdoors) as their source for heating and cooling.

Other types of heat pumps are called Geothermal heat pumps - they draw heat energy from the ground outside (below the frost line) to heat, or pump excess heat energy into the ground to cool. They do this by transferring heat energy through a series of coils that are buried deep in the ground. You may not realize it but below a certain depth the temperature of the ground remains fairly constant year-round.

Carbon Monixide & Mold Indoor Pollutants

Carbon Monixide & Mold Indoor Pollutants

What is carbon monoxide?

Carbon monoxide is a colorless, odorless and tasteless gas, and it is hard to detect without a carbon monoxide detector. It very efficiently and quickly reduces the amount of oxygen in the blood. Low levels over long periods of time are dangerous, and high levels can cause unconsciousness and even death. To keep your indoor air clean and healthy, make sure that fuel-burning devices are well vented.

Sources of carbon monoxide that can pollute indoor air:

• Fuel-burning appliances such as furnaces, fireplaces, gas stoves and water heaters (especially those that are not properly vented or maintained) or when chimneys are blocked or dirty;

• Idling vehicles in garages that are attached to homes or buildings;

• Barbecues, grills, space heaters and other non-vented fuel-burning appliances that are designed for outdoor use; and

• Tobacco smoke.

The most common symptoms of CO poisoning are

• Headache
• Dizziness
• Weakness
• Nausea
• Vomiting
• Chest pain
• Confusion

Mold Can Be More Harmful Than You Think

What is mold exactly? Is mold a plant or an animal? Believe it or not mold is neither plant nor animal but it actually is a fungus. Mold can be found on old crusty food, on walls and ceilings of your home. Mold can be found anywhere there is moisture. Mold can be made into Penicillin which has saved many lives. It is amazing how mold can be harmful and yet help save lives. Mildew is also another name for mold.

Mold is a living organism and has a very important role in our environment.

First of all, mold grows in areas that tend to have a great deal of moisture, darkness, and heat. Most areas you may find mold are bathrooms, pool areas and even in kitchen cabinets, floor tiles and even books. Mold can pretty much grow anywhere as long as its conditions are right. Mold spreads pretty fast and can take over a home if you don’t have the proper mold remover to fight against the spread of mold.

Mold spreads by reproducing or regenerating the cells which are called spores. These spores once airborne can latch on to clothes, skin, pets and even air condition filters. There is no way to keep mold spores from entering your home. The best way is to buy certain mildew or mold removal products. You can fight off the spread of mold and keep it at bay.

Mold can be very harmful to your health. Mold is very harmful to your lungs. Sometimes you don’t even realize there is mold in your house or work place. Mold is also very harmful to people with allergies and may trigger an allergy attack. Most of the time you do not realize that mold is making you sick until it is too late. Some of the symptoms are an excess of coughing and chest pains from coughing.

Some other symptoms are shortness of breath or even a scratchy throat.The only way to find out if you have a mold problem is to have your home or place of work inspected. It may be a little pricey but a mold technician can come out to your home and take some samples.

The technician will take some samples from outside and inside the home. This will determine if the mold spores in your home are growing more rapid than outside. You have a problem if the mold spores are growing more in the home rather than outside.

You can fight the outbreak of mold spores with special mold removal products.

There are also mold cleansers that block the mold spores to prevent the mold spores from coming back. One of the main ingredients in these mold spray is bleach. When buying a mold remover product check and see if it is odorless.

The odorless ones will not make your eyes tear when using them. Spray the infected areas and start scrubbing. You should repeat this process in one week’s time for a month and you will see a difference.

Mold is a very important part of our environment but can be a problem to humans as well. Mold can never be destroyed but it can be controlled. You can fight mold spores to keep the mold from spreading by using the correct mold removal products. It is so ironic that mold can help save human life and also help take it as well.

Cupola Furnace HVAC Product Locator

The cupola furnace has received a large amount of negative attention as of late.

However, the system does have a few inherent benefits over electric furnaces. One it is simple and economical to operate.Second a cupola is capable of accepting a good range of materials without reducing melt quality, so it’s recycling ability is excellent. They therefore play a vital role in the metal recycling industry. Third Cupolas can refine the metal charge, removing impurities out of the slag. This is usually because they derive energy without delay from coke instead of from electricity that first needs to be generated. The successive instead of batch process suits the demands of a repetition foundry. * Cupolas can be employed to recycle foundry spinoffs and to break other pollutants like VOC from the core-making area.

Induction Furnace And Cupola Furnace Information

In Metal Casting, the type of furnace you have at your foundry, or workshop determines a lot of the work you can or can not do. Many metal casters enjoy making their own furnaces and have done so quite successfully. The plans for home made furnaces are eagerly shared among the enthusiasts so finding blueprints and instructions should not be difficult. But before you rush off to find the blueprints you may want to take time to learn about the types of casting furnaces available to help determine which one will suit your needs. This is not saying that you should only have one furnace at any given time, but this way you will know what project will work best for which furnace.

BOOK

 Iron Melting Cupola Furnaces for the Small Foundry

 Cupola

Cupola furnaces are among the most popular with backyard foundries. Many casters construct their own cupola which proves to be cost effective and highly efficient if done properly. Since cupola furnaces can achieve high melting temperatures they are primarily used for the melting of iron and bronze, though aluminum can also be melted when attention is paid to keeping the temperature low. The primary fuel source for cupola furnaces are coke using limestone for flux.

By not using a crucible, the Cupola furnace is able to melt the metal at a faster rate. While individual designs of these furnaces differ due to varying resources and design ideas, the basic component of a cupola furnace is the same. The cupola furnace must be elevated above the ground and installed with a drop bottom usually hinged, which will allow the excess metal, fuel source, and other waste to drop from the furnace. The tap hole and shaft which will allow the molten metal to flow from the furnace and into the ladle and air shafts are also required. A slag tap hole can be placed on the furnace usually in the back, higher then the tap hole, which will allow the slag to flow out easily.

With most small home foundries, the cupola furnaces are preferred over that of other furnaces for its high melting rates and for how easily the construction of such a furnace can be.

Reverberatory

The Reverberatory Furnaces are commonly found in industrial plants but there have been quite a number of home grown foundries that have used this furnace type with much success. The basic idea of a Reverbeatory Furnace is to use the heat reflecting off a surface, usually brick, to heat the metal, which is aluminum in most cases. This way, the metal does not come into contact with the fuel or the flame. This process is also used in Puddling Furnaces. The name Reverberatory and Puddling are often used interchangeably. By placing the metal in a shallow depression and then directing an intense flame over that depression and to the wall, the heat rebounds to melt the metal. Many casters will adjust the length of the flame since a longer path will mean that the heat will be more intense.

There are many designs for the reverberatory furnace, all of which will include exhaust ports and the rear of the furnace must be able to withstand the intense heat and be able to bounce it back into the chamber.

Bronze, aluminum, tin, and many other ores can be melted in a reverberatory furnace all depending on the construction of the actual furnace and the heat of the flame. This type of furnace has been around since at least the Middle Ages and was used primarily for bronze work.

Electric Arc

Electric Arc furnaces are normally used in Industrial foundries. Most hobby casters do not use these furnaces due to cost, space issues, and a general inconvenience. There are two forms of the electric arc furnace, the direct and indirect.

The direct arc has three electrodes which are used to heat metal by way of the arc. This creates an incredible amount of heat and so water jackets and other cooling devices will be needed for operation.

The indirect arc just uses one electrode and works in much the same way as the direct arc furnace.

Electric Induction

Electric Induction furnaces are becoming all the more popular with large industrial size foundries that enjoy the clean burning and efficiency of an electrical furnace. Copper coils surround the crucible with the metal inside which can reach extremely high temperature suitable for melting most metals.

Rotary

The Rotary style furnaces are hailed for their ease of use being fully or at the very least partially automatic. These furnaces tend to be harder to construct though there are resources and companies online that sell rotary furnace.

The different furnace types do affect the quality of the work being produced, so it is important to keep that in mind as you cast. With a little trial and error, you should find the perfect furnace to fit your needs so you can start building one of your very own.

 HOW TO SAVE MONEY & MAKE YOUR AIR CONDTIONER LAST LONGER

Replacing your air conditioning filter regularly will make your air conditioner run smoother,  improve its efficiency, can prolong the life and save you money on your utility bills. When you do not replace your air conditioning filter indoor air pollutants such as dirt, dust and grime impede the flow of  clean air, forcing it to bypass the filter with this action the dirt gets carried directly into the evaporator coil. This is a bad, as the coil is the part of your air conditioner that absorbs heat, you want to keep the coil clean to keep it functioning smoothly and to prevent your compressor and fans from failing.

 If you or anyone in your family suffers from athsma or other breathing problems, keeping you indoor air clean by changing the filter will keep you healthier, and breathing easier.

Where is your air conditoner filter?

Your air conditioning filter will be located somewhere along the duct that returns air from the house and to the air conditioner. Filters are often located in the air conditioner itself or in ceilings, walls or furnaces.

What kind of an air conditioning system do you have?

Many air conditioning have filters made just for that model. Air condtioning can also use different filtration methods to clean the air. To determine which system you have, remove the filter and if you are unsure of size or type take it along to the store, and get exactly the filter to fit your ac model.

How ofter do I need to change the air conditioner filter?

If your air conditioning unit is using disposable rather that reusable air conditioning filter, depending on where you live it is a good idea to check your air conditioning filter every month. If you live a rural communitiy with dirt roads, have pets, smoke, or live in a city with a lot of pollution you may need to replace your filter every month during the summer season.

Saving money on your utility bill

If you do not change your a/c filer during heavy use you will put a heavier strain on the unit, which will work hard, and break sooner. The cost of a/c filters in nominal in comparison to added costs each month on your utilities, and having to come out of pocket for a large expeniture when you have to purchase a new a/c unit.

Remember this fact; Keeping the filter clean can lower your air conditioner’s energy consumption by 5%–15%.

So consider getting air conditioner filters or furnace filters that do not generate any ozone.

Prescription Checklist:

Change or clean your furnace and air conditioner filters once a month or according to the filter manufacturer’s instructions. Increased dust could be a sign that it is time to change a dirty furnace or air conditioner filter or vacuum cleaner bag. my furnace air conditioner filter seems to contain an inordinate amount of dust despite regul… my furnace air conditioner filter seems … my furnace air conditioner filter seems to contain an inordinate amount of dust despite regular replacement. High-efficiency electrostatic air filters should be used in air conditioner and furnace systems. You also need to check the filter when running the central air conditioner, because air circulates through the furnace and the filter. Finally, these filters are called furnace filters, or air conditioner filters, because they are designed to filter the air going to the equipment. Furnace and air conditioner filter ratings, reviews and comparisons.

Change the air conditioner’s filters regularly

Dirty filters restrict air flow, reduce efficiency and worst case, can cause the evaporator to ice up. Dirty filters reduce the efficiency of the air conditioner. The most important maintenance task that will ensure the efficiency of your air conditioner is to replace or clean filters monthly. A dirty air filter reduces airflow and operating efficiency and, in some cases, can damage a room air conditioner. The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. To ensure the efficiency of your air conditioner, routinely replace or clean the filters.

 Can Air Cleaning Devices Clean All Pollutants?

No, the power to remove particles, including micro-organisms, does not mean that filter and portable air cleaning devices are cleaning all the of the indoor air pollutants from inside your home, but these air cleaning devices do have the capability of reducing adverse health effects from indoor pollutants for individual such as children, the elderly, and people with asthma and allergies.

 The use of clean air filters is your best defense  against indoor air pollutants. This is the simplest way to regulate or eliminate the sources of pollutants, and to ventilate a home with clean out of doors air. While air cleaning devices may help to manipulate the levels of airborne allergens, particles, or, in a few cases, gaseous pollutants in a home, they may not remove all health hazards such as noxious gases from indoor air pollutants.

 Air Pollutants Indoors

What are the pollutants that can affect our indoor air quality in a home:

    * Particulate matter can includes dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses.
       
    * Gaseous pollutants are noxious and come from combustion sources.These sources include gas cooking stoves, vehicle exhaust, and tobacco smoke. They also come from building materials, furnishings, and the use of products such as adhesives, paints, varnishes, cleaning products, and pesticides.

When you are making decisions about using air cleaning devices, consumers should also consider:

    * Installation: In-duct air cleaning devices have certain installation requirements that must be met, such as sufficient access for inspection during use, repairs, or maintenance.
       
    * Major Costs: These include the initial purchase, maintenance (such as cleaning or replacing filters and parts), and operation (such as electricity).
       
    * Odors: Air cleaning devices designed for particle removal are incapable of controlling gases and some odors. The odor and many of the carcinogenic gas-phase pollutants from tobacco smoke will still remain.
       
    * Soiling of Walls and Other Surfaces: Ion generators generally are not designed to remove the charged particles that they generate from the air. These charged particles may deposit on room surfaces, soiling walls and other surfaces.
       
    * Noise: Noise may be a problem with portable air cleaners containing a fan. Portable air cleaners without a fan are typically much less effective than units with a fan.

Air Conditioner Filters Tutorial

One of the most important things to maintain on your new cooling unit is the air conditioner filter. Dirt and debris in the filter will reduce the air flow and thus the effectiveness of your conditioning unit. Once your air conditioners filtering unit becomes very clogged with dirt and debris, those dirt particles will bypass the filter and start messing up the air quality along with the machines working parts.
                                                                 

While some air conditioner filters can be cleaned and reused, some need to be replaced altogether. If the filter on your cooling system can be replaced, it should be done or at least checked every month or two. Just like in any machine, the frequency that you change your air conditioning filters depends on the external operating conditions. Dusty environments combined with heavy use will speed up the need for a cleaning or replacement of your systems filters.

Traditionally most simple air conditioning unit filters were made from foam, fiberglass or another washable screen type material. These air conditioner filters collect particles via a sticky surface of oil or similar substance. One draw back with foam units is that there is a risk of small foam particles mixing into the expelled air. The second is that foam air conditioner filters wear out quicker than some more modern conditioning unit filter types.

The newest type of air conditioner filter is the electrostatic mesh. Electrostatic filters are neat in the way that they filter air compared to the old "sticky grab" method. The movement of air across the air conditioners synthetic weave of fibers creates a static charge that collects the dust on the filters surface. A side benefit to this electric charge on the filters surface is that is creates ozone which helps to kill bacteria and unpleasant odors.

You should change your air conditioner filters at regular intervals because when your filter is new, it grabs up to 10% of the dust and particles that cross over its oil filmed surface. As time passes more dust gets trapped in the filter, which is a good thing, but all those extra particles will cause less air flow to get through. By keeping your conditioning unit inspected and maintained at regular intervals will not only save you money in electric bills and repairs but also keep you air quality supremely conditioned.

What is the best make of air conditioner filter? As with all types of consumer products, there will varying opinions and lots of marketing to deal with. Often when trying to find a new product the best thing to do is ask the opinion of others. Air conditioner filters are no different. There are several websites and forums where you can go and look through the consumer reviews and make a better decision as to what air conditioner filter would best suit your needs.

HVAC Looks At Indoor Pollution

 Indoor Pollution

 You have possibly heard in the news, read on the internet or news paper that the air we need to sustain our planet is getting worse. Did you see China before the olympics? Everyone wearing face mask, beacause just by being outdoors they were exposed to pollution so potent that it was equal to smoking 3 packs of cigarettes  a day. What about the air in side homes in China? Do you think that the people there are wearing masks indoors? The pollution problem is not only Chinas, but the worlds problem. With trees are being cut the deforestation is going to affect all of us. The population is growing which of course leads to the addition of more automobiles on the road, and massive factories to produce all the wares the population demands. The air is starting to become extraordinarily polluted, and the clean air and clean water we take for granted everyday, may soon be unbreathable. The solution to the worlds pollution is going to global efforts from government, and citezens around the world. We  can do our part to help keep our plant clean, and we can also keep ourselves healthier by keeping our indoor air in our homes clean. Pollutants in the home that can also cause acute respiratory problems, and luckly many can be prevented with proper maintance of your homes air filters.

 Do you think your home air is cleaner than the air outside?

Think again……. no, the air within your house is up to ten times more polluted than the air outside. The reason behind this is the air within your place has no way to get circulated around and so the air get obstructed with all kinds of chemicals and dust. Since the majority spend up to ninety percent of their time inside this could be a major problem.

The air circulating within your home if full of dust, smoke, pollen, animal dander, tobacco smoke, particles generated from combustion appliances such as cooking stoves, and particles associated with tiny organisms such as dust mites, molds, bacteria, and viruses. Other items that can pollute your indoor air are from chemicals such as household cleaning items, but indoor pollutants can also come from sources like your fireplace, leaky gas stoves or radon an invisible gas that is trapped inside your home. It can come up from the ground, and it is undetectable, but it can cause breathing problems and cancer.
If you suffer fromh asthma, enphasema, or any other respitory problems you may already be affected by the invisible pollutants in your home. With all these pollutants floating around, many invisable to the naked eye, you may not realize how toxic the air in your home is. If you have a chronic cough, runny nose, itchy eys, you may want to check your home for  unseen pollutants.
 The long term affects of breathing polluted indoor air, can take many years to materialize, but if you live in area of the country that has a high pollution index outside as well, you may feel the affects much sooner. 
 
You may not have many options for when you are outside, but when you are in your home, you can use air conditioner filters and furnace filters that remove dust, pollen, allergens, smoke and other particles from the air so your family can breathe easy. Change them on a regular basis, the little extra time and money you spend now may pay you back many times over, as you will be healthier, and spend less money on doctor bills and medications.

HVAC Your Health and Your Furnace

HVAC Your Health and Your Furnace

One of the most typical health issues that plague our society is dehydration.

The majority of the tissue in the body is made of water. If it loses the water, the tissue dries up.

It’s elasticity goes, and with it function declines.

Conditioning the quantity of moisture in the air with a furnace humidifier is need for your health. Dry air in your house can make your throat feel dry, and cause or irritate respiratory illnesses. The heating seasons causes folk to start having repeated attacks of winter colds.

Essentially, for many dry air is an air-quality issue. How will a furnace humidifier have effects on your comfort? Humidity in the home will have effects on your comfort. By giving up moisture to the air, your skin, throat and nasal passages dry out and crack leading to numerous physical pain. Nearly everything in your house made of wood contains some moisture. As dry air sucks that moisture out, the wood shrinks and cracks. Hardwood floors separate at the seams, furniture shrinks and cracks, and doorways warp and no longer fit their frames as the moisture is drawn off. Also, maybe the most irritating effect of dry indoor air is static shock. How often have you shuffled across the carpet, only to be insultingly stunned by the crackle of static as you reach for the light switch. It’s no fun when it happens to you, and even less so when you reach out and "zap" a friend or family member. With the capacity to grip a static charge up to twenty thousand volts, your body can also do serious damage to home PCs and other sensitive electronic devices. By maintaining indoor relative humidity at 35 % or higher with the application of a humidifier, static shocks are seriously reduced.

Are there any other advantages to installing a furnace humidifier in the home? Warm, humid summer air feels warmer than it essentially is due to the moisture it contains. That same principle is applicable to your house in the wintertime. By keeping the relative humidity within your house at the ultimate level, you can turn your thermostat down some degrees and still feel cosy. Dialing down your thermostat just three degrees can scale back your heating bill by as much as 5%.

How Your Home Can Benefit From A Furnace Humidifier

Home improvements are big business these days, with many home owners spending a great deal of money on improving their houses and apartments. However, there are also ways of keeping your home and belongings in good condition without spending a fortune on repairs and decoration. One appliance that can really help to keep your home in good condition is a furnace humidifier. This appliance serves as a valuable tool min improving the air quality within the home, which can then eliminate the risk of damage to your home, your belongings, and your health. Over recent years, air cleaner and humidifier prices have become far more affordable, so now many more people can benefit from the benefits that this type of equipment offers. You can enjoy keeping your whole house in good condition, from your kitchen and bathroom to your bedroom and living areas, when you use a furnace humidifier.

How can a furnace humidifier help?
When you have a home that is beautifully decorated and furnished, the last thing you want is to have all of that ruined due to dry air. The climate within your home can have a surprising effect upon everything within it, and by using a piece of equipment such as this you can inject moisture back into the air, thus alleviating the level of dryness and eliminating the problems that can be created by lack of moisture. However, it is not all about maintaining the decoration and furniture within your home – even more importantly, using this type of humidifier can also have an impact upon your health. Dry air can create and exacerbate a number of health problems, from allergies and skin conditions to respiratory problems. By improving the air quality with a humidifier you can vastly reduce the risk of these health problems, thus enjoying a far better quality of life when at home.

HVAC Comparison Electricity Propane Fuel Oil Furnace

 
Oil Furnace Verses Gas Furnace

The future is here as some heating companies have abandoned servicing oil furnaces because their liability insurance rates had increased substantially, and the quantity of oil furnaces was declining. If you live out in the country, natural gas is probably not available. The option open when you live rurally is to have a propane company install a tank. They will install the tank and supply line for almost nothing, and then regularly give large rebates on your first fill up.

Many years ago, oil was the fuel of choice for people who didn’t have natural gas service; however oil is not a clean burning fuel. If you have an old oil furnace, and you are thinking of switching to gas does yourself a favor; you might remove the back access panel on the oil furnace, and look at quantity of soot in the heat exchanger. You might be surprised at what you find. Take a look at the bottom one-third of the passageways; are they blocked by what looks like yellow bricks?  If so, that is actually blocks of sulfur.

Furnaces from as recently as 20 years ago may offer half of the heat production of today’s more energy efficient models, while releasing significantly more harmful gasses into the atmosphere. You will find that  natural gas furnaces emit  very little gas making  the need for a chimneys are a thing of the past. You can pipe from the basement to the outside as narrow as eight inches is enough for a natural gas furnace to work efficiently. However, with an oil furnace, their exhaust fumes must be heated to a higher temperature in order to rise and escape and this requires that flues be at least 18 inches wide to release harmful gasses properly.

Efficiency

Fuel oil has very high sulfur content. It has been stated that the sulfur content is around 3,000 parts per million, which would be 0.3%. For an impurity, that is a very high concentration. For an impurity, that may be an extremely high concentration. The Gas furnaces runs about 94.1% to 97.0% Efficient and compared to oil burn extremely clean Carbon monoxide levels are extremely low around 18-20 ppm (acceptable levels are anything below 75ppm) if they are properly installed.

Maintenance

Another question is do you as the home-owner want to deal with accumulated sulfur and soot removal with a yearly furnace cleaning? With an oil furnace an once a year cleaning and service call is really obligatory, as the soot must be removed from the heat exchanger. Also, the oil spray nozzle should to be replaced and the air-fuel ratio adjusted to reduce soot buildup. When the soot builds up, it begins to restrict the flow of combustion gases. If this gets bad enough, it could cause the furnace to stop working, or worse, can send combustion or noxious gases into the house.

Gas and propane furnaces do not have the same maintenance needs as oil furnaces. Gas and propane units need the air filter to be replaced monthly, and it’s a good idea to vacuum the dust off the blower every year, but you may find that gas and propane burners can get a small amount of soot buildup, but they can go 10 or 20 years with nothing more than a wisp of ash. The up keep cost on a gas or propane furnace is going to be lower than an oil furnace in you compare the maintenance costs. The maintenance on an oil burner alone could boost your heating costs if it’s done every heating season as recommended.

Furnaces manufactured after 1992 in the U S are required to have AFUE ratings of 78% or more, most furnace models today exceed these minimums. While both oil and natural gas furnaces can now provide significantly more heating power than they could earlier, technological limitations prevent oil furnaces from being able to reach the AFUE scores in the high 90% range that some natural gas furnaces already have. For every percentage point higher the AFUE rating is, the more money you will save over the life of the furnace.

Electric Furnaces

Natural gas is not only considered a clean-burning fossil fuel, but it’s also more efficient than electricity when used for household heating.

Switching from gas to electricity would run counter to many state’s energy efficiency goals because using electricity for heating is about 2 1/2 times less energy efficient than using natural gas, according to Neal Elliott, associate research director at the American Council for an Energy Efficient Economy, a Washington nonprofit that promotes efficiency.

"The bottom line for use is fuel switching," said Angela Townsend, spokeswoman for PSNC. "If the ultimate goal is to truly promote energy efficiency, an incentive program wouldn’t allow customers to switch over to electricity." It seems buying or replacing an old furnace, the  gas furnace is still the better fuel efficient option.

 Upgrade

Upgrading your heating equipment to natural gas will save money you money in the long haul. Making the decision to have a high-efficiency gas furnace installed will provide you with quieter and cleaner burning unit. Since a gallon of liquid propane has less energy than fuel oil (about 92,000 BTUs versus about 130,000 BTUs for oil) the actual annual heating cost may be slightly higher than with fuel oil, but the maintenance costs may even it out. Your home air will be cleaner,  and you will not have to  smell laden air in your home, which your lungs may thank you for later.  Read up indoor air pollution here.

HVAC Product Locator Geothermal Heat Pump More Efficient?

 HVAC Heating Your Home With Geothermal Energy

HVAC (heating, ventilation, air condtioning unit) Geothermal heat pumps provide the most earth-friendly home heating and cooling system available. Installing a geothermal heatpump system, you’re investing in a naural heating souce that will uses less energy, provide for our childens future as it keeps the air clean and fresh. It emits zero pollutants, in your home, and provides cost effecting heating.

During the heating season, according to EEER ( gov energy ) a ground-source heat pump supplies three to four units of heat to your home for every unit of electrical energy required to operate the system. So you get two to three kilowatt hours (kWh) of free energy for every one kWh of electrical energy you pay for. In other words, a ground-source heat pump is 300% to 400% efficient.

Don’t forget the tax incentives when you install a geothermal heat pump system.

Geothermal heat pumps are like standard heat pumps, but use the ground rather than outside air to provide heating, air conditioning and, often hot water.

As they use the earth’s natural heat, they are among the most productive and comfortable heating and cooling technologies now available.
Energy star geothermal heat pumps state that ENERGY STAR qualified geothermal heat pumps use about 30% less energy than a standard heat pump.
They are quieter than conventional systems. Very reliable 95-98%

In the winter the normal heat pump system extracts heat from outdoor air and transfers it inside where it is circulated through your home’s ductwork by a fan.

Even cold air contains a great deal of heat; the temperature at which air no longer carries any heat is well below -200 degrees Fahrenheit. That is not too common an occurace.

How Does Geothermal Energy Work?

How does geothermal energy work is a good question, and one which I have often been asked. In this article I must first explain what it is, and then how it can be made to work for man.

Geothermal energy is, literally, the heat of the earth. The heat itself derives from radioactive decay beneath the earth’s surface and, in certain locations, it is concentrated enough and is close enough to surface waters to be brought to the surface by local geological features.

Geo-energy was once thought of as nothing but a thing to wonder at, but it is thought of very differently, now, and is considered by many as one of the most promising forms of renewable energy. It is a renewable energy source because the hot water which conveys it is replenished by rainfall and the heat it brings with it is continuously produced inside the earth.

The great thing about it is that as a form of energy it is versatile and reliable and it produces electricity which generally produces none of the greenhouse gases associated with the combustion of fossil fuels.

So, geothermal energy is the power which can be generated by the harnessing of the heat beneath the Earth’s surface. Deep wells are usually used to pipe steam and hot water from deep within the Earth, up to the surface.

Geothermal heat comes from the magma in the earth’s core, and that itself is heated by the radioactive decay of uranium, thorium, and potassium present in the core. Geothermal energy is present everywhere beneath the Earth’s surface, although the highest temperature, and thus the most desirable, resources are concentrated in regions of active or geologically young volcanoes.

Though the resource is thermal energy rather than a physical substance such as gold or coal, many aspects of geothermal energy are analogous to characteristics of mineral and fossil-fuel resources.

Geothermal energy works for us when, for example, is used as to warm the water in fishing farms. The water is heated, and the warmth makes it more possible for alligators, tropical fish, and other types of fish to grow in seasons and places where they wouldn’t normally.

There are some limitations to it as a form of energy. Unfortunately, the best geothermal resources are concentrated in areas of volcanic activity and are not widely distributed. The earth’s centre is a distance of approximately 4000 miles from the surface and is so hot that it is molten, but when the heat does not rise to the surface it is too far to drill down to the center.

When used in a power station geothermal heat from the hot water from the well causes a ‘secondary fluid’ to turn into vapor, which as it expands drives the turbines to produce electricity. Since the technology used in a binary-cycle geothermal power plant is a closed-loop system, nothing is emitted to the atmosphere. After turning the turbine generator, the working fluid is condensed back into liquid, which is repeatedly vaporized by the geothermal heat in a continuing cycle.

Dry steam and flash steam power plants do emit low levels of carbon dioxide, nitric oxide, and sulfur, although reportedly at only roughly 5% of the levels emitted by fossil fuel power plants. However, geothermal plants can be built with emissions-controlling systems that can inject these substances back into the earth, thereby reducing carbon emissions reportedly to less than 0.1% of those from fossil fuel power plants.

Dry steam plants are used when the rock is very hot. They take steam out of fractures in the ground and use it to directly drive a turbine that spins a generator. Flash plants take hot water, usually under pressure and at temperatures over twice the normal boiling point of water, out of the ground. They allow it to boil as it rises to the surface then separates the steam phase in steam/water separators and then run the steam through a turbine. The turbine also turns a generator, and from that comes the electrical power.

Temperatures in the Central Texas hydrothermal aquifers range from about 90 degrees Fahrenheit to 160 degrees F at depths from 500 to 5,000 feet. Historically these waters have seen some application in spas and therapeutic baths, but might also be developed for geothermal winter heating if used with heat pumps.

If you were to ask the average Icelander; ‘How Does Geothermal Energy Work’. He would probably say; ‘very reliably’ and, ‘our country shows how it can work very well’.

Iceland takes advantage of its incredible geological structure to use geothermal power to their advantage. Recently, it has been reported that 17% of Iceland’s total electricity production comes from geothermal energy. Iceland has reached uniquely high levels in the utilization of geothermal energy, but the resource could be better utilized globally. Iceland is very lucky when it comes to energy as it gets almost all of the rest of its electricity from Hydro-power dams.

Energy from geothermal sources today has been said to amount to less than 0.1 percent of the global world use.

Currently in the US, the author understands that, only four states generate electricity from geothermal resources. In total, this provides electricity for about 3.7 million people.

HVAC Discover the Benefits Of Geothermal Heat Pumps

HVAC Discover the Benefits Of Geothermal Heat Pumps

Discovering the benefits of geothermal heatpump systems , is very exiting to anyone who is looking for to lower their utility bill, have a clean source of energy, and is environmentally conscience. Geothermal heat pumps tap into the earth just a few feet underground, to produce clean efficient energy that is completely under utilized. Geotheramal heat pumps are reliable, and unlike oil we will never run out of it.

The Benefits Of Geothermal Heat Pumps

A Geothermal Heat Pump (GHP) is an apparatus that extracts heat from below the surface of earth. It works on the principle that heat flows from higher temperature substances to lower temperature substances via conduction or via convection (air currents). Geothermal Heat Pumps take in heat from the earth or water bodies to provide space and water heating. This works since the earth traps nearly half the sun’s energy that is received by the earth.

Ground source heating and cooling will give great comfort and be cost-effective with environmentally-friendly technology which uses our planet’s ability to store energy as heat. Geothermal heat pump systems move the heat from Earth or from water into buildings, or from buildings right back into Earth. A little bit of electricity is employed for operating fans, pumps, controls, and a little compressor.

GHPs utilize the relatively constant temperature of the ground or water several feet below the surface as a source of heating and cooling and are appropriate for both retrofit or new homes. In addition to space heating and cooling, geothermal heat pumps can provide hot water with virtually no additional energy requirements because GHPs don’t create heat; they merely move it from one area to another.

This is a relatively new technology that can save homeowners money
Although the initial cost of a new geothermal system is generally more expensive than a traditional heating and cooling system, the extra investment is returned within five to ten years. The ground loop piping is estimated to last over fifty years, and even the internal parts have about a 25 year life span. Every year about 50,000 new geothermal heating systems are added in the United States. They’re very reasonable for most areas and can use the Earth for heating when temperatures drop and as a heat sink when it’s hot outside.

Quite a number of new residential systems come with desuperheaters, by which excess heat is transferred to the home’s hot water storage tank from the geothermal heat pump’s compressor, providing a highly efficient means of heating water. But in the spring and autumn, during which the geothermal heat pump system does not operate, the desuperheater will not provide hot water. However, because of the geothermal system’s significant advantage in efficiency compared to other water heating methods, ‘full demand’ systems using a separate heat exchanger to meet hot water needs cost-effectively are now being offered by some manufacturers.
