supply solar water heater with copper coil as heat exchanger

Ten advantages show the advanced technology:
All-glass evacuated tube adopts vacuum insulation, and the thermal preservation of water tank is foaming of polyurethane at high pressure. Our products  are configured with energy saving standard, which solves the heat loss caused by the heat transfer, heat conductivity and heat radiation.
Heat exchange instantly,water plentiful
It can use the pressure of tap water, comfortable and economical
it can reduce hot water rapidly, so it can produce the high quality hot water
it can produce more hot water than the general types because it isn’t restricted by the volume of the tank
Fresh water quality, live water supply
Temperature invariableness, comfortable and safety
Hot and cold separate, never breakage
Energy storage, anti-freezing
Working with intelligent, easy and reliable
Perfect pursuit
