Everything You Should Know About Solar Water Heating

  

Many folks have heard of solar heating nowadays more folks are using it to heat their houses and pools and to save lots of cash on their energy bills. But even if somebody has heard of solar heating they may not be acquainted with the systems!

How Do Solar Heating Systems Work?

Most people consider passive solar heating to be the most cost-effective way of providing heat for a building. This is because the amount of solar energy that typically falls on a building in a day is more than enough to power and heat that same home for the day. When passive solar heating systems are used in a building’s actual design, it costs nearly nothing extra and results in a huge reduction in energy costs.

When a home has a passive solar heating system, the house itself basically becomes the collector for solar energy. Each surface of the home that’s exposed to the sun’s rays is picking up them. To adequately collect this daylight, a passive solar heating system needs south facing glass and thermal mass to take in, distribute and store the heat.

The commonest kind of passive solar heating system is known as a direct gain system. This system uses tangible living space as a solar collector daylight comes into a room, strikes thermal mass materials in the house and gets kept where it raises the room’s temperature!

What Types Of Solar Collectors Are Used For Solar Water Heating?

There are three types of solar collectors used in residential homes that are using solar water heating systems. A flat-plate collector is a waterproof, insulated box that has a dark absorber plate underneath a glass cover. Plates used when solar water heating pools typically do not have a cover on them.

Integral collector-storage systems, sometimes called batch systems, feature one or more black tubes or tanks that are contained in a glazed, insulated box. Cold water passes though the solar collector in this solar water heating system and the collector preheats the water. The water then filters into the conventional water heater and then to the home’s pipes.

And finally, another type of collector is called an evacuated-tube solar collector. These collectors have parallel rows of glass tubes that are transparent. Each individual tube has a glass “outer” tube and then a metal tube which is attached to a fin. The fin’s special coating absorbs energy and keeps heat in. This type of solar water heating collector is typically used for more commercial aspects.

There are also two main types of solar water heating or solar pool heating systems: direct circulation systems and indirect circulation systems. Direct circulation systems circulate water for the actual household through the collectors and then into the home. This type of system is used in climates where the temperature never falls below freezing. Indirect circulation systems actually circulate a non-freezing fluid through the collectors and then through a heat exchanger. This heats up the water and then filters it to the home.

Considering all the perks that go along with a solar water heating system it’s really no wonder people are converting.
