The air source evi heat pumps are finished and arranged delivery to Eastern Europe
The Enhanced Vapour Injection (EVI) technology is adoppted on this heat pump, so we also call it EVI heat pump.
As we have experienced, the effective working temperature of the conventional air source heat pump is only -5°C and the heat performance sharply decreases in the very cold winter. OurEVI heat pump has overcome this difficulty successfully . The EVI heat pump can normally work at -25°C. It can supply the hot water up to 50°C even in the very cold winter. With EVI heat pump, you can enjoy the comfortable heating and hot water all the year around no matter where you are.
