Kensa Contracting has won the contract to deliver England largest shared ground loop heat pump system alongside French utility company, ENGIE.
Shoebox heat pumps manufactured by sister company Kensa Heat Pumps will be retrofitted at 400 flats in eight tower blocks in the London borough of Enfield. Planned for completion in October 2018, the heating upgrade is expected to reduce residents’ energy bills by 30-50%.
"Not only do ground source heat pumps provide the lowest cost heat, they also deliver substantial carbon savings, and landlords benefit from the exceptionally low servicing and maintenance costs.''
The district ground source heat network system at Enfield will feature 16 shared ground loop systems serving the eight tower blocks. Each district system will typically consist of clusters of eight boreholes serving individual heat pumps installed within the flats of half a tower block.
This system allows each resident to select their own preferred energy supplier to access the best available electricity tariff. The shared nature of the ground array design also reduces drilling costs and ensures funding through the Energy Company Obligations (ECO) Scheme as well as the Government’s Non-Domestic Renewable Heat Incentive (RHI), securing Enfield Council quarterly payments for 20 years.
Kensa Heat Pumps will be sharing project progress updates on its blog.
