Non-pressurized system is the most economic solar water heater which work stable and no need any maintenance. It must be installed on the top, such as roof, to get enough hot water flow pressure by the gravity. With the assistant tank or water tower, could be feed water automatic.
A controller can operate the electric or show temperature and water level inside the water tank.Specifications:| Description | Solar Water Heater |
