EVI Air Source heat pumps transfer heat from the ambient air to water, providing high-temperature hot water up to 60°C. The unique Low ambient-temp heat pump is widely used for house warming. With innovative & advanced technology, the direct-heating heat pump can operate very well at -25℃ ambient temperature with high output temperatures up to 60℃, which ensures the compatibility with normal sized radiator based systems without supplementation. Compared with traditional oil/LPG boilers, high-temperature heat pump produces up to 50% less CO2 whilst saves 80% running cost.
