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 ultra-efficient heating solution.

A Shared Ground Loop Array heat pump system features individual heat pumps in each property, all fed from the same central ground array. This ground array can be made up of either coiled pipe known as slinkiesboreholes or pond mats, and it is sized to deal with the peak heat demand of all the dwellings combined.

How much will multiple ground source heat pumps cost?

Use Kensa’s costed examples below to find the recommended ground source heat pump design for your self build project and establish the heat pump installation costs.

Four Kensa Evo ground source heat pumps connected to a shared ground loop array of pond mats could cost £52,000 and earn you £170,000 of income from the Non Domestic Renewable Heat Incentive (RHI).

Costed examples for water source

Have you got a pond or stream on your land?

Water is an excellent conductor of heat and therefore water source ground source heat pump systems are extremely energy efficient when coupled with Shared Ground Loop Arrays. See how much Shared Ground Loop water source heat pump systems cost.

Costed example for slinkies

If your land contains fields or paddocks, then slinkies would be a viable option for a ground source installation.

Slinkies are the name given to coiled pipe buried in trenches at a depth of 1-2m where the ground temperature remains constant all year round. See how much Shared Ground Loop slinky heat pump systems cost.

Costed example for boreholes

If your site is in a urban area with limited exposed land or a small garden, then boreholes might be a viable option.

Boreholes can usually be drilled into any type of ground and are a perfect space-saving solution, as the depth of the hole(s) is varied to suit the heat requirement. See how much Shared Ground Loop borehole heat pump systems cost.
