Kensa Engineering, the only UK manufacturer of a complete range of ground source heat pumps, has released the first commercially available 12kW single compressor heat pump, operating on single phase power supply.

In a domestic application twin unit, up to 24kW of heat can be provided which is the largest available single phase heat pump on the market. The 12kW unit is fitted with a brand new model of Copeland compressor, which provides a Coefficient of Performance of 4 at an inlet ground temperature of 0ºC and a load side outlet temperature of 35ºC.

The units are fitted as standard with a ‘high power’ Smart Start to limit the effects of a large current draw when the compressor starts. This means that the starting current is reduced from 125 amps to only 36 amps, making it much more acceptable for domestic single phase electricity supplies, reveals the company’s press release.
