The latest advances in acoustic insulation and vibration mitigation minimise the Evo ground source heat pump’s acoustic signature.

A unique floating sub chassis prevents vibration and noise passing through the unit, sandwiched by thick acoustic insulation fully lining the inner chamber.

The Evo ground source heat pump has been designed to be easy to handle and install.

Cross head screws provide easy access to the Evo’s electrical component and wiring terminals behind its unique bevelled front panel.

  • Curved cut-outs offer an extra level of installation flexibility, with vertical and horizontal pipework exit points from the sides and top of the unit.
  • Four rear water connections, two for the ground collectors and two for the property’s heating distribution system, consist of 28mm straight brass fittings. These are designed with tight tolerances to ensure compatibility with easy to install push fittings.

  • Optimised sized stainless steel heat exchangers allow the compressor to respond more efficiently.
  • Fixed speed scroll type compressors deliver the highest efficiency possible. (Read our blog: Fixed speed compressors VS inverter driven heat pumps)
  • Energy use is further minimised thanks to Kensa’s pioneering self-adjusting pressure controlled hot water system and optional use DHW boost controller, which are synchronised to the heat pump cycles.
  • Built in water pumps for both the ground and heating side.
  • Modulating fluid pumps can be commissioned to exactly meet the flow needs of the unit. The load side pump automatically modulates between normal and setback speeds, depending on the operating state, to minimise the pump energy consumption.
  • The latest advances in heat exchanger design have aided the reduced temperature difference across the heat exchangers to improve efficiency. The Evo ground source heat pump also includes a small third heat exchanger that recovers internal waste heat from the compressor circuit.
  • DNO friendly ‘Soft Starts’ fitted as standard on single phase models to ensure peak starting load is minimised.
  • Energy Networks Association (ENA) Connect & Notify approved**.
  • Weather compensation fitted as standard.

Warranty & Accreditations


  • 5 year warranty for the heat pump unit.
  • 2 year warranty for the controller and water pumps.
  • 2 year internals warranty.


  • MCS
  • ISO9001
  • ErP A++
  • Energy Networks Association (ENA) Connect & Notify approved**
  • Winner: Heat Pump Product Of The Year, ACR & Heat Pump Awards 2018
  • Winner: Best Sustainable Technology / Product, Build It Awards 2017
  • Finalist: Domestic Heating Product Of The Year, H&V News Awards 2018

I can’t believe how quiet the heat pump is! We don’t have the door on the utility room yet and you can hardly hear it running at all.

The Evo is modern and contemporary, but still has the same simple set up as all of Kensa's products.

Example: One Building

A ground source heat pump provides heat and hot water to your home by harnessing solar energy stored in the ground (or other heat sources such as the water in rivers and lakes). The heat is extracted via pipes either buried in trenches, secured to a pond mat submerged in the water, or installed vertically…

Example: Multiple Dwellings

Where there are multiple dwellings on one site all requiring heating and hot water, installing a Kensa ground source heat pump inside each dwelling connected to a Shared Ground Loop Array provides a unique opportunity to receive an even more lucrative return on investment through the Non Domestic RHI, whilst providing a low cost and…

Kensa went on site with long-standing Partner Installer, Edward Savage of EPS Plumbing, Heating & Green Energy, to demonstrate the key points of an installation of a Kensa Evo ground source heat pump in a complete barn renovation in West Cornwall.  Ed has undertaken all of the plumbing and heating throughout the build in addition…

Blog: Fixed speed compressors VS inverter driven heat pumps

Why does Kensa not manufacture inverter driven heat pumps? 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 heat pump manufacturer, favours fixed speed compressors in our units whilst…
