Trent & Dove, Phase Two

Setting up the drill rig

Ground Source Review: Chestnut Mews & Aspen Mews.

As a result of the successful deployment of Kensa ground source heat pumps into 133 bungalows owned by Trent & Dove Housing, the housing association subsequently commissioned Kensa Contracting for a second phase of installations for two blocks of three-storey flats.

Ground Source Review: Chestnut Mews & Aspen Mews

Chestnut Mews and Aspen Mews are made up of two blocks of three story flats, totalling 60 units. Using Kensa’s innovative shared ground loop arrays solution, linking the ground source heat pumps in each flat to a common ground array, Trent & Dove were able to offer their tenants controllable, affordable warmth, whilst at the same time accessing significant upfront grant funding via the ECO and 20 years of income via the Non-Domestic Renewable Heat Incentive (RHI: this scheme has now closed – please visit this page to explore other funding).

The 60 flats were connected to 40 boreholes across 12 ground arrays, forming clusters of shared ground loop arrays. With each flat receiving its own small and compact Kensa 6kW Shoebox Twin heat pump fitted inside the home, tenants retain individual control, and importantly, individual billing. And as the circulating pumps to the boreholes are individual to each unit, there are no centralised running costs to manage and bill.

The final heat pump commissioning was witnessed by Lord Bourne of the Department of Energy & Climate Change (DECC) who visited tenants homes to see for himself the benefits of renewable heating solutions for social housing.

Lord Bourne expressed his admiration for the scheme and the innovative way it accesses streams of government funding, saying:

Social housing tenants in East Staffordshire are saving hundreds of pounds on their energy bills thanks to Trent & Dove’s innovative project, in partnership with Kensa. It’s great to see Trent & Dove putting the consumer at the heart of their plans, leading the way for others to follow.
