This installation in a new build development in the London Borough of Islington is a prime example of how networked ground source heat pumps in high-density urban areas can provide the most efficient, lowest carbon and lowest cost heating and cooling solution for developers, local authorities and residents.

Kensa’s ground source heat pumps will be providing passive cooling, as well as heating and hot water to the new development at the York Way Estate. This ultra-low carbon solution will help reduce emissions, improve air quality and protect residents from fuel poverty.

A mixture of 3kW and 6kW Kensa Shoebox heat pumps will be installed into the new flats. These ground source heat pumps will extract naturally occurring heat from the ground surrounding the development via clusters of vertically drilled boreholes. It uses this renewable heat to deliver heating and hot water into the homes.
