17.8kw Heat Pump Water Heater with High Cop for Europe

Product Description

17.8Kw heat pump water heater with high COP for Europe
EVI air to water heat pump is specially designed for house heating and sanitary hot water in cold area. The ambient temperature range is -25DC to 43DC. It can use safely in -20DC ambient with strong low-temperature heating capacity

Adopting the most advanced low- temperature Enhanced Vapors Injection compressor technology. EVI heat pump delivers higher heating capacity at low evaporation temperature thereby better responding to heating requirements than normal air source heat pump, it also results in less supplementary heating to cover the full heating demand on the coldest days. It has been further optimized to enable heat pumps to efficiently produce water temperature up to 60 DC during cold winter time.
