It is a non-pressure solar water heater system, which converts solar energy into heat energy and stores it in the insulated water tank. It is a natural circulation that relies on its own gravity to drain out of water from tank. As the tank can not bear any pressure so it is a open type water solar heater and generally also known as low pressure solar collector as well. Due to its convenience on installation and daily use, low cost, as well as to meet the hot water needs of normal households, this solar boiler is currently the popular product in the market.
