Introducing an evolutionary new ground source heat pump series.

Available to pre-order now for spring delivery.


  • The Evo offers a 15% gain in efficiency, minimising running costs & maximising income via the Renewable Heat Incentive (RHI).
  • Heating & hot water efficiencies of SCOPs to 4.7 at 35°C.
  • 60°C domestic hot water.
  • Industry-leading noise reduction.
  • Cross-head screw access, revolutionary rear cut-outs & push-fit water connectors allow easy and flexible installation & maintenance.
  • Packaged in a stylish yet durable gunmetal & gloss-white finish.
  • Punctuated by a custom built control panel unique to the Evo series.

Ideal for:

Larger new builds and renovation projects.ErP a++


  • 7kW, 9kW and 13kW models meet the heat demand of a wide variety of house sizes in the UK.
  • Optimised sized stainless steel heat exchangers allow the compressor to respond more efficiently.
  • 15% efficiency enhancement.
  • Increased Seasonal Coefficient of Performance (SCOP) to 4.6 at 35°C.
  • Delivers 60°C domestic hot water.


  • Significantly reduced noise.


  • The Evo has been designed to be easy to handle and install.
  • Cross head screws provide access to the Evo’s electrical component and wiring terminals with the removal of just one panel.
  • Four rear water connections, two for the ground collectors and two for the property’s heating distribution system, consist of 28mm straight brass fittings designed with tight tolerances, ensuring compatibility with easy to install push fittings.
  • The external side panels feature a curved cut-out offering an extra level of flexibility to install the Evo according to the demands of the site, with vertical and horizontal pipework exit points from the sides and top of the unit.

Power saving

  • DNO friendly ‘Soft Starts’ fitted as standard to ensure peak starting load is minimised.
  • Weather compensation fitted as standard.


  • Kensa has developed its own control board which is the brain of the new Evo heat pump.
  • The customer interface is an intuitive touch screen that facilitates commissioning and parameter settings.
  • Provides live status readings.
  • Pro-active system pre-empts system irregularities using warning safety levels, enabling better diagnostic and faster system resolution, reducing costs and potential call outs.
  • Simple and easy to navigate menu structure with default settings that can be reset with a touch of a button.
  • In-built sensors and probes enable remote commissioning.


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

* The COP figure quoted is calculated as per EN14511.

** In-built immersion heaters will increase running costs and CO2 emissions as they use direct electricity, because of this Kensa heat pumps do not include them.

*** By increasing the flow temperature from the heat pump the efficiency of the unit will drop and the COP decreases.

**** Kensa Evo heat pumps incorporate smart starts as standard to limit the starting current of the compressors. For full details on how the starting currents are calculated please contact Kensa.

Note: Design flowrates are for a ground temperature of 0 and –3oC and a load temperature of 30oC and 35oC
