Ground Source Review: Coastline, Wheal Vyvyan

Coastline Housing and Kensa Contracting replaced inefficient night storage heaters in a group of bungalows situated off the gas grid.

The project benefited from a combination of funding including the Non-Domestic Renewable Heat Incentive (RHI), an up-front grant from the Energy Companies Obligation (ECO) and new funding offered by DECC in the form of the Central Heating Fund (CHF).

The Wheal Vyvyan estate had six communal boreholes drilled by local drilling contractor Aquasource to an average depth of 60m, feeding 12 individual 3kW Shoebox heat pumps.

Resident Ms Osnebury commented:

Very pleased on affordability – was approximately £30 per week now £12 per week – and I can stay nice and warm for that! I have never been happier. No damp problems now – all gone.

Ralph Retallack, Energy Efficiency Manager at Coastline Housing said:

I would strongly advise other social landlords to be open to this technology as an option. Ground source heat pumps are very low maintenance, there is simply not much to go wrong. The boreholes provide sufficient energy to meet each property’s full heating and hot water needs. We were very impressed with the small size but high efficiencies of Kensa’s innovative Shoebox heat pumps. From start to finish the project with Kensa has run extremely smoothly.
