Meiguang solar hot water heater best for family us

Our solar hot water heater has the following absolutely advantages:1. High efficient. With high-tech patent(National Patent No 201030214510.1), our solar water heater can collect more solar energy.We combine the ø47mm and ø58mm vacuum tube together.The ø47mm vacuum tube has highersurface-mass ratioso that it canheat waterquickly and efficiently.Theø58mm vacuum tube can obtain more water and have high capacity.2.Less water loss. Using our another patent(National patent No.201020235866.8)called New Breathing Valve, we can have less water loss from the tank.The new breathing valve on the tank is just like a cork on the thermos bottle. When the water becomes hotter,the pressure in the tank will increases, then the valve will open andthe pressure decreases.Atnight, the breathing valve is closed to prevent theheat loss.3.Eco water purifier.Ecological water is energetic and hardly produce water scale, so that it can keep the tank clean inside. With smaller molecules, ecological water will take out the dirty in skin more easily and keep the skin moisture as well. Also the ecological water can improve our skins by inhibiting the bacteria and add mineral composition to skins.3 built-in filter layers, Maifanite layer, active carbon carrying silver, mineralize ball and siliphos(silicon and phosphorus) filter layer, all of these can efficiently intercept different kinds of dirty in water, including silt, rust, humus and so on. The dirty removal rate is higher that 95%.
