vacuum tube solar water heater with copper coil

Vacuum tube solar water heater with copper coil(SPHE) provides mains pressure pre-heatingvia a highlyeffectivecopper coil heatexchanger located within the solar collector tank. The way in which the mains pressure solarcollector heats water is the same as the non pressure solarcollector. Rather thanusing the water in the tank directly, as the non pressure does, this type uses a 45-60mcopper coil. Heat exchager inside the tank provides more than 1.5m2 of heat transfer area. When water flowsthrough the coil it absorbs heat from the water inside the solar collector tank. The solar collector tank is therefore a thermal store. --------------------------------------------------------------------------------------------------------------- The features of vacuum tube solar water heater with copper coil(SPHE): 1. With CE,ISO certification. 2. High quality copper coil heatexchanger, whichcan transfer the heat energy efficiency. 3. Long life-span. No needextra after installation. 4. Easy operation. 5.
