※ Energy saving and low cost. German imported copper core with Nitrogen TiO2 coating (this technology is in world leading position in application of solar energy, sunshine absorption over 95%), make full use of solar energy, to save energy by 70-80%, therefore save the energy cost.
※ Safe and reliable. No danger of burning, explosion, poison and electric shock common water heater has, so it is the most reliable and safe heater system.
