Characteristics
Solar water heater is designed to efficiently collector radiation and to convert it into usable heat energy for household hot water usage. Do not use it for heating or storing anything except POTABLE water.
Solar water heater has no moving parts and operates on local water pressure and solar radiation. There are no pumps or controls to maintain and no electrical energy is required to make it function. Once the system has been set up, it will operate at the flow rates that are normal to the household. The solar vacuum tubes of the unit absorbs solar radiation through its highly effective coating surface and raises the temperature of the water stored in the tank.
