Homegrown ground source heating for Cornwall homes

Truro-based ground source heat pump manufacturer and contractor, The Kensa Group, is deploying networked heat pumps to provide 140 new homes in Quintrell Downs, Newquay, with low-cost, energy-efficient heating.

Cherilyn Mackrory, (3rd from R) was shown around the new development by Kensa CEO, Tamsin Lishman (3rd from L)

Cornish MP, Cherilyn Mackrory joined Kensa chief executive, Tamsin Lishman, for a close-up tour and demonstration of the renewable heating system being installed, which will save residents hundreds of pounds in annual heating costs.

Each modern home will have its own ground source heat pump connected to a Shared Ambient Heat Network, giving residents access to an effective, year-round clean heating system.

This significant project comes as Kensa plans to deliver 70,000 heat pumps nationwide by 2030, a move that will create over 7,000 green jobs and help bring people out of fuel poverty.

Tamsin said: “I was delighted to show Cherilyn how Kensa’s ground source heat pumps will supply new homes with low-cost, energy-efficient, low-carbon heating.

“What we’re doing here at Quintrell Rise is a great example of how networked heat pumps are a perfect green heating solution for new housing developments, benefiting both consumers and the environment.

“This model can be deployed at scale for new build developments across the country, and can even be replicated for complex-to-decarbonise properties like retrofit high-rise flats or terraced streets.”

Mark England, head of innovation, sustainability and procurement at Coastline Housing, said: “Renewable heating schemes such as this are a fantastic addition to any new housing development. It means reduced costs for customers moving forward with their energy bills and it’s also much more environmentally friendly so it’s really a win-win.”

By having a ground source heat pump connected to the shared network, each home at Quintrell Rise will experience reliable heating with low running costs. Homes with ground source heat pumps also produce around 80% less CO2 than if they were supplied by gas.

Key development stats:

• Estimated annual cost for each home to power their heat pump is between £211 - £388 per year, depending on property size - significantly lower than if the properties were heated by electric panel heaters

• 140 Kensa Shoebox heat pumps to be installed

• 58 boreholes across the development

This latest development follows other energy-saving projects completed by the Cornish company, including the ground-breaking Heat the Streets project in Stithians, the retrofit of 273 high-rise flats in Thurrock and the installation at Trelissick House, an 18th-century National Trust property in Truro.

With the Future Homes Standard set to effectively ban installations of gas boilers in new build homes from 2025, ground source heat pumps are expected to be an essential solution for the Government to meet its target of 600,000 heat pump installations a year by 2028.
