—— Product Description ——
Withair® EVI Heat Pump is specially designed for cold climate region and adopts Ultra low temperature Enhanced Vapour Injection(EVI) compressor technology to guarantee a stable running even at -25°C.EVI heat Pump solve the client's room heating and hot water supply during the very cold climate region. (EVI compressor - enhanced vapor injection,Vapor-injected method can effectively improve heat capacity, prevent higher discharge temperature of compressor and guarantee operating stability of unit at low temperature).
Withair® EVI heat pump is one of the most economical systems to heat the water for family domestic use. Using free renewable energy from the air, the unit is highly efficient with low running costs. Its efficiency can be up to 3~4 times more than conventional gas boiler or electrical heater.
