Solar Heating Systems

Solar Heating (Solar Thermal) Systems

Using solar energy to heat your water is one of the most practical and cost effective to exploit the energy from the sun. Solar thermal systems absorb the sun's heat and use it to heat your home hot water needs. In general, solar thermal water heating easily to 140 º F or more corresponding to the range of its traditional counterpart hot water tank. Effective systems can save up to 70 percent of solar energy that reaches them and transfer it to you.

How solar hot water heating work

In general, there are two types of water activates the heating: direct and indirect.

Direct solar water heaters

As implied, direct systems capture the sun's heat in collectors to directly heat the water for a household. The system consists of collector pipes filled with water that are linked to an insulated storage tank usually located inside a house. As the sun heats the water inside pipes, water flows into the storage tank. Although direct systems are more efficient than indirect ones, they require more maintenance to keep the pipes clear of ore deposits. Direct solar thermal systems also work best in warm climates where the system is less sensitive to frost.

Indirect Solar Water Heating

Indirect systems does not heat water directly rather they use fluid with a low freezing point to absorb radiant energy from the sun. Also termed the closed-loop system, an indirect water heating system absorbs solar sunlight into heat pipes evacuated of air which in turn warms the thin copper laminate tube at the rear of each tube. The table collection consists of several heating pipes that are fitted and tilted to maximize solar collection.

Often glycol (an ingredient in antifreeze) circulates through the pipes in the adjacent matrix and is heated by contact with copper laminated. As the temperature increases pipes, heat activates a pump that circulates the glycol fluid in a heat exchange coil in the water tank. This coil, in turn, transfers its heat to the water tank and voila, hot water is produced.

Swimming pool and hot tub solar heating systems

systems, solar pool heating operates on a principle similar to a direct solar water heater. However, because the water is too warm in a thermal solar system, the glazing of the collection is often removed. Use pipe, non-glossy or a heating system that looks like a black carpet mat prevents pool water to become super-heated and reduces overall system costs.

While solar pool and spa heating systems are often exempt from federal and state monetary incentives and rebates, they often pay for themselves within 1-5 years (depending mainly on where you live ).

Radiant heating systems for your home

You can also use a solar hot water (or thermal) system to heat your home. Rather than transferring the heated water to a hot water heater, solar water heater can be connected to a floor heating and / or a wall panel radiator.

You can perform the collection and distribution systems that use simple or complicated as you want depending on your location, climate, and intended. Most radiant heating systems use the collection chart for heating water and storing it in a large thermal collection tank so that you have enough heat to last at least overnight. A general rule is to have a collection tank that can store 1 ½ to 2 liters of water for every square meter of solar collector. This water, in turn, is routed via plastic tubing under floors to create an efficient heating system.
