Pre-heated Pressurized Solar Water Heater:
Standard export packing, special packing for sample.
Also named thermosiphon solar water heating system, this type of solar water heater is such a water pre-heating system with a pile of copper coil installed inside water tank as heat exchanger. Firstly, water in inner water tank will be heated enough by solar accumulation through vacuum tubes, when water from tap goes through copper coil, it will be heated by the hot water surrounded copper coil all the way till out, in the way we get instant hot water which is much more healthy and not limited to the capacity of water tank, and inside copper even makes it a more comfortable pressurized system which could be connected directly with tap water. With an additional auxiliary tank, the system will work automatically to refill water into water tank.
