Nicholls Boreholes: Ground Source Heat Pump in Buckinghamshire

Nicholls Boreholes: Ground Source Heat Pump in Buckinghamshire


Ground Source Heat Pump

South East


Mr & Mrs Mackenzie had always been very eco-conscious, but when their first grandchild was born a few years ago, reducing their carbon footprint became a priority. Knowing what a big polluter their old combi oil boiler was, the Mackenszies decided to replace it with a renewable energy alternative, a Ground Source Heat Pump.

About the project

The Mackenzies took on a key part of the project management and enlisted their own builder and electrician to support on various tasks. Nicholls dug three vertical 100 metre boreholes spaced evenly apart in the garden.

A separate groundwork team then dug two one metre deep by one metre wide trenches for pipework which would connect the borehole heads to the plant room and then from the plant room to the house.

Nicholls then installed and tested the pipework connecting the boreholes to the plant room. The Nicholls plumbers and electricians installed the heat pump, exchange equipment and water tanks in the plant room. A plumber removed the oil boiler and then connected the equipment to the existing.

The Heat Pump Experience

“Our ground source heat pump is running smoothly and is providing perfect heating and hot water all year round. We’re so glad we made the move to not only reduce our carbon footprint, but this technology will also give us the opportunity to save up to 70% on our fuel bill, in comparison to our old oil boiler.”

“We were very impressed by the hard work and professionalism of the several Nicholls teams who worked on our system. It is clearly not an easy operation to carry through successfully, particularly when it is not possible to be certain in advance as to the geology that the borers will meet. We were filled with admiration at watching each of the teams tackle its particular aspect of the project: first the borers, then the headerwork team, followed by the guys installing the pump and tanks. We look forward to many years of quiet reliable heat and hot water without the guilt of burning oil.”
