Using high-technology of heat pump, 65-80% of running cost can save compared with other heating machines(such as the fuel gas boiler, electric boilers, etc).Absolutely no air pollution.

Flow switch built-in, automatic defrost, antifreeze protection function.

Using patent technology double titanium heat exchanger coil,more stable performance, higher COP value.what's more, the heat exchanger is high pressure-bearing, can bear 21 kg water pressure.
