Installation of a Kensa ground source heat pump is a relatively simple affair, as Kensa heat pump systems are specifically designed to be installed by contractors without the need for specialist training.  Any competent builder and plumber should be capable of installing them.


The key to a good heat pump installation is the application engineering; this is carried out by Kensa Heat Pumps in the initial stages of any project.


This allows end users to select contractors who they have a good working relationship with and reduces the cost of installation.

Full guidance on heat pump and ground array installation are available in the Knowledge Hub.

It would be sensible to split the overall installation scope so that a separate contractor is handling the groundworks. If there is sufficient land for slinkies, any groundworks contractor would be able to dig the horizontal trenches – following a plan supplied by Kensa – and install the pipework leaving the plumbing contractor to perform a pressure test. If vertical boreholes are required, Kensa Heat Pumps can recommend a number of drilling contractors who, generally, would also install the pipework and grout.

The groundwork contractor is merely providing a connection to the ‘heat source’ in the same way that the utility companies are responsible for providing connections to the gas, electricity or water grids. In a typical project featuring a gas boiler, the plumber would only be responsible for installing the boiler and would not handle the provision of the gas supply to the property. Kensa is merely mirroring this approach.

Myth busting

Kensa is a manufacturer with an objective to remove any mystery linked to ground source heat pump technology and the installation of the appliance.

The most challenging element to any project is the application engineering to ensure the correct sizing of the groundworks, heat pump and distribution system.

Far more straightforward is the physical on-site work linked to the installation of the ground source heat pump. This work can be handled by any plumbing contractor without the need for prior experience, extensive training or specialist tools. If MCS accreditation is in progress or not yet achieved, Kensa may provide an MCS umbrella service to ensure the installation complies with criteria for the Renewable Heat Incentive (RHI).

As a result, plumbers already working for the contract builder can provide the service eliminating the need to contract with ‘specialist’ installers who might seek premium rates for their supposed ‘expertise’. It should be emphasized that the installation of a heat pump should take no longer than the fitting of a gas boiler, once the groundworks have been completed.

As Kensa ground source heat pumps are fitted with a multitude of sensors, the units can be commissioned by a Kensa engineer over the telephone to reduce project costs.

To ensure quality installations, Kensa’s Approved Installer Network provides an extensive list of ground source heat pump contractors that have been vetted by Kensa to provide a quality installation – and strictly no ‘cowboys’.

The range of Kensa products are straightforward to install and they work very effectively.
