    Stainless Steel Heat Pipe Solar Water Heater , Glass Tube Solar Water Heater

    Heat pipe solar water heater is an innovated product, the biggest advantage of this product is that the superconducting heat pipe is designed to make the system run under pressure, and the efficiency is higher than flat panel solar collector.

    Heat pipe solar water heater system is especially suitable for private residential use. There are normally 2 systems, one is compact thermosyphon type, it need without pumps and temperature difference circulation system, capacity from 150-320L. The other type is the separated pressurized, which requires pumps and temperature difference system workstations, capacity of 150-500L.

    Both of the 2 types systems can meet the hot water demand of different size households in an all-round way.
