Heat pumps support DHW generation

AMBIflo air-source heat pumps from Andrews Water Heaters are now available with two outputs, 16 and 20 kW, with COPs of 3.9 and 3.2, respectively, at an ambient air temperature of 2°C and a water temperature of 35°C. These COPs improve to 4.6 and 3.6 at an ambient temperature of 7°C. They are designed to support gas-fired water heaters in the production of domestic hot water and reduce carbon emissions and running costs. They can also be used as part of an underfloor space-heating system.
Their design provides flexibility of installation. They are available with left- or right-hand plumbing connections. Anti-vibration mounts are supplied as standard.
Each unit is a self-contained unit with a closed and precharged refrigerant circuit.
