Solar Water Heating System

Solar thermal collectors convert sun energy to heat inside the collector is an absorber system.

The absorber traps the radiation inside, converting it to heat.

This absorber is made of a high-conductivity material (copper or aluminum) to increase heat transfer. It is treated with a selective coating to improve heat absorption. A heat transfer fluid, non-toxic antifreeze (propylene-glycol mixed with water), passes through the absorber.

Once warmed, this fluid transfers the heat energy to a hot water tank. A heat exchanger is used to avoid contamination of drinking water. This occurs within a separate closed loop system. Solar thermal systems can be used all year round. Thermal systems can provide domestic hot water.
