Solar Water Heater System - Stainless Steel Inner Tank, Hot Galvanized Sheet Steel Outer Tank, High Efficiency Evacuated Tubes With 20-year Lifespan, Energy-saving Polyurethane Insulation

we are the famous exporter, manufacturer and supplier of solar water heater system in Dezhou, Shandong, China. The evacuated tubes have two layers of glass tubes, the inner tube absorb solar radiation then convert into heat energy and transfer it to the water in inner tubes. As we know, the density of water in different temperature is different, so the hot water circulates to the water tank, cold water in tank flowing into tubes, through this natural circulation, the water will be heated. The solar water heater tank is a non-pressurized tank, and has an opening to the ambient atmosphere. Solar water heater tank should always be filled with water to avoid damage caused by dry high temperature working conditions. The stainless steel our use belong to food grade, and SUS 304 & SUS 316 have better corrosion resistance.
