Installation Instructions

Based on reverse Carnot cycle, the refrigerant in the evaporator absorbs a large amount of energy from the air, which is then compressed into high temperature and high pressure gasby the compressor and finally exchanging heat through the heat ex-changer, so as toprovide house heating and hot water.
Environment-friendly. No combustion. No exhaust emission |
Save 50-80% energy compared with electric heating |
All-weather hot water supply. Heating in winter. Cooling in summer |
Electricity & water separated. No safe hidden danger |
