Ground source heat pumps increase energy efficiency and saleability

Designed to a high-end specification with a focus on sustainability, each property in this trio of luxurious, high-quality new-build homes benefits from an ultra-modern Kensa Evo ground source heat pump.

Netherfield is an exclusive development of six (only three available for sale with a price tag of £1m each) individual detached family homes set within private gated grounds on the edge of the village of Probus in Cornwall. The luxurious three-floor houses are built near the picturesque Roseland Peninsula looking out over a stream, fields and trees.

Designed to a high-end specification by Jack Burr at Kwalita Design Solutions, a local Cornish architect with a focus on sustainability, each property benefits from the lowest carbon heating technology available; ground source heat pumps.

Kensa’s Evo was a perfect fit

Kensa’s products are all designed for British properties and ‘connect and notify’ approved – this meant there were no conformity issues with Western Power. With a highly efficient output and stylish design, Kensa’s Evo heat pump, was a perfect fit for the development. A mixture of 9kW or 13kW Evo’s was installed in each property. The heat pumps are either housed in a dedicated plant room utility area in the basement or tucked away in a garage space.

The fact that the ground source heat pumps have the ability to cool without having to install an additional dedicated cooling unit is a real benefit. Lots of glass is being used in the design, and so the cooling functionality is being considered, although it hasn’t been specified yet.

Individual boreholes saved space

Three 80m boreholes were drilled for each property in phases in line with the build schedule, with trenching and manifolds following after. The borehole drilling rig had to navigate the site which was tight in places with obstacles such as drainage. Consequently, some of the boreholes were drilled at a slight angle to get the correct separation between them.

A highly efficient system design

Working in partnership with Kensa meant that the architect and installers were able to design a highly efficient ground source heat pump system. A concrete finish was used on a number of floors and the properties have underfloor heating throughout, which enhances the efficiency of the ground source heat pumps.
