Kensa’s Twin Compact Ground Source Heat Pump Series boasts a bigger heat capacity thanks to the use of two compressors. As a result, Kensa’s Twin Compact Ground Source Heat Pump series includes the largest single phase ground source heat pump on the market.
Twin Compact: In Brief
- Twin Compact Ground Source Heat Pump Series features 12kW – 30kW models, including 24kW single phase.
- High Temperature models designed for larger, older properties.
- Three phase models suited to particularly large properties.
- Hybrid models blending the efficiency of standard models with the output of high temperature models.
- Dimensions HxWxL (mm) – 900 x 900 x 570
- ErP A++ rated efficiency.
- 16kW, 20kW and 24kW Twin Compact ground source heat pump models deliver temperatures to 50°C.
- 12kW and 17kW High Temperature Twin Compact ground source heat pump models deliver temperatures to 60°C.
- 15kW and 21kW Hybrid Twin Compact ground source heat pump models blends R134a and R407c refrigerant to deliver efficient space heating and high water temperatures to 60°C.
- 20kW, 24kW, and 30kW Three Phase Twin Compact ground source heat pump models suit high heat demands of larger, three phase properties.
- High specification acoustic hoods and double vibration isolation reduce noise and vibration.
- DNO friendly ‘Soft Starts’ fitted as standard to ensure peak starting load is minimised.
- Two temperature set points (one for heating and one for domestic hot water) produce the required heating at the highest efficiency without the need for costly direct immersion heaters.
- Ability to modulate between full and half loads to reduce power consumption and running costs.
- Weather compensation fitted as standard.

Why Kensa does not manufacture inverter driven heat pumps Guy Cashmore, Technical Director and co-founder of Kensa Heat Pumps, says: Using an inverter compressor with an air source heat pump system is almost a no-brainer because of the fluctuating source air temperature. However, we often get asked why Kensa, as the UK’s leading ground source…
