Delivering retrofit ground source heat pump installations at scale is key to achieving our carbon reduction targets – 80% of the building stock that will exist in the UK in 2050 has already been built. By engaging the rented and owner-occupier sector to deliver community-wide ‘heat the street’ schemes, Kensa is future-proofing our buildings of yesteryear.
Kensa’s philosophy for retrofit private housing heating upgrades is for a street-by-street, area-by-area basis, rather than house-by-house. This approach has significant benefits, including:
Working in areas of a single decision-maker, i.e. privately owned blocks of flats and estates, Kensa’s approach ensures government subsidy can allow large numbers of people to connect at the same time.
Kensa’s innovative Shared Ground Loop Arrays link a series of boreholes to multiple properties, including flats, via an ambient temperature distribution system.
Each property then has an individual Kensa heat pump wired to their own electricity supply, which upgrades the low temperature ground heat for heating and hot water within their dwelling.
Properties featuring Kensa’s Shared Ground Loop Arrays will provide end users with numerous unique benefits over traditional Heat Networks:
GSHP’s produce 3-4kWh of heat energy for every 1kWh of electrical energy used, making them 300-400% efficient. Compare this to a typical boiler, which is just 90% efficient. Kensa’s ground source heat pump systems offer the lowest fuel costs.
Because a GSHP extracts so much “free” energy from the environment, this enables CO2 emissions to be lower than any other type of heating system.
GSHPs don’t require annual servicing or maintenance, and have an expected lifetime of 20 years.
With an individual ground source heat pump in each property, homeowners are in complete control of their own heating and energy bills, enabling easy energy tariff switching and payment only for their own heat consumption.

With heat being generated at the point of use (inside each dwelling) the ‘heat’ circulating the property is low temperature, therefore there are no heat losses from the system to contribute to overheating in risers and corridors. The low temperature system also allows for free passive cooling to be introduced, creating a comfortable living environment all year round.
1m below the surface the ground temperature remains a fairly constant 8-10°C all year round, ensuring your heat supply is constant and reliable; unlike air source heat pumps, which are impacted by external fluctuating air temperatures causing higher bills when heat is most needed.

Summary: Kensa looks at what air pollution is and the culprits that contribute to it – impacting public health and the economy. We also look at how ground source heat pumps, as electrically-driven heating systems, can reduce air pollution. Read more at KENSAHEATPUMPS.COM A 2020 study from CBI Economics & Clean Air Fund…
