Solar water heater with overhead stand means cold water tank bottom level should be at height of 6 feet from the place of installation of solar water heater so that when we use hot water in bathroom, cold water automatically enters in solar tank from overhead tank. In this type of installation electric back-up with thermostat of 2 to 3 KW can be installed in solar tank for cloudy weather. Although, during rainy season ETC solar gives hot water even if there is partial sun light during day time. We can directly use this temperature hot water for bathing which is between 30 deg to 50 deg. If its continuously raining during whole day and weather is cold, during such days we will not get hot water next day.
