ETC Solar Manifold Gives perfect hot water output due to exact Square Meter Collector Area as per defined absorber area parameters compared to Solar Tubes Directly inserted in Tank Systems. ETC manifold solar water heaters are ideal for places which require hot water in quantities like hostels, hotels, industries, apartments, hospitals, community halls etc.

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.

olar Water Heater (ETC System) works on a simple principle ‘Black body heat absorption principle’. The principle says, ‘black colour absorbs maximum heat, more than any other colour’.Solar water heating systems using vacuum tubes made of borosilicate glass with special coating to absorb the solar energy are called as Evacuated Tube Collector system (ETC Systems).
