Example: Multiple Dwellings (small)

With Kensa’s ambient-temperature Shared Ground Loop Arrays suiting as few as two connected properties, small luxury developments are increasingly turning to this cost-effective and energy efficient heating and hot water system.

Qualifying for a guaranteed income through the Non Domestic Renewable Heat Incentive (RHI) for 20 years, small developments featuring Shared Ground Loop Arrays have the opportunity to generate a 6-13% IRR for the developer, significantly offsetting the costs of the installation.

Compatible with all Kensa collector arrays, discover the best Shared Ground Loop Array for your small development and establish the costs using our costed examples.

District ground source system

Small developments featuring Kensa’s Shared Ground Loop Array have individual Kensa ground source heat pumps in each dwelling, connected to clusters of ground arrays.

These ground arrays can be made up of either coiled pipe known as slinkiesboreholes or pond mats, and they are sized to deal with the peak heat demand of all of the connected dwellings.

Costed Example: Water (Pond mats)

If your development has access to a stream, river, pond or lake, then you should consider harnessing this freely available energy source.

Water is an excellent conductor of heat. Therefore small developments featuring Shared Ground Loop Arrays utilising water as the heat source are extremely energy efficient.

Costed Example: Soil (Slinkies)

If the plot is rural and surrounded by lots of exposed land area, then Shared Ground Loop Arrays featuring slinkies as the ground array collector 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.

Costed Example: Rock (Boreholes)

If the development is in an urban area and has limited exposed land, then Shared Ground Loop Arrays featuring boreholes as the ground array collector would be the best option.

Boreholes can usually be drilled into any type of ground and are a perfect space-saving solution.

Shared Ground Loop Arrays featuring boreholes are ideally suited to larger projects with a minimum of 20 properties. Indeed, boreholes are the most prevalent of all Shared Ground Loop Array collectors.
