Pre-heating Freestanding Evacuated Tube Low Pressure Solar Water Heater
This type of solar heater provides mains pressure pre-heating via a highly effective copper coil heat exchanger located within the solar collector tank. Rather than using the water in the tank directly, as the non pressure does, this solar water heater uses a 45 m copper coil. Heat exchanger inside the tank which provides more than 2.5 m2 of heat transfer area. When water flows though the coil it absorbs heat from the water inside the solar collector tank. The solar water tank is therefore a thermal store and amount of water you can draw is not restricted to size of tank.
For the present, our company has obtained CE Certification, the SOLAR KEYMARK and SRCC are testing in Germany for TUV. Furthermore, we have advanced testing devices, high level and highly qualified production team and perfect after-sales services.
