The basic principle of solar thermal heating is to utilize the sun’s energy and convert it into heat directly. Main components are a solar collector, pipework and a storage tank. Sun energy is trapped inside a collector. The absorbed energy transforms into thermal energy and is transferred to a fluid that circulates through pipes in the collector.

The heated fluid from the collector rises to a heat exchanger inside the storage tank and will transfer its energy to the drinking water in the inner fresh water tank. After the liquid has released the heat, it flows back to the collector for reheating.
