Ground source heat pumps, supplied by Sheffield-based Danfoss Heat Pumps UK, are helping to provide green energy for a £5 million social housing development near Pontefract.
Danfoss secured the contract after main contractor Mansell recommended the Sheffield firm, after working with it on a recent social housing project in Rotherham.
We were impressed by the technical support we have received when we worked before with Danfoss Heat Pumps UK. The installation was very successful there, so we were confident about recommending their heat pumps on this project too,” said Mansell senior quantity surveyor Steve Seedhouse.”
The heat pumps extract heat from the ground and will maintain a continuous supply of domestic hot water, as well as supplying an underfloor heating system on the ground floor and radiators on the first floor.
Heat absorbed from the ground is transferred to a liquid refrigerant, which circulates in a 90 metre loop of piping, buried in a vertical borehole in the back garden of the homes.
The liquid evaporates to form a gas, which is then compressed, causing its temperature to rise, before passing into a condenser where it starts to change back to a liquid as heat is transferred into the building.
Danfoss director Chris Dale said: “An increasing number of social housing providers are investing in heat pumps both to reduce carbon emissions and to provide their tenants with a means of low cost heating. This is preventing them from falling into fuel poverty due to the impact of rising energy prices.”
Ged Walsh, from Yorkshire Housing, added: “We are always looking for reliable and sustainable products that will have a real cost benefit for our tenants.”
