Heat Pump Case Studies: Ground Source Heat Pump in 3-Bed New-Build

Property type: 3-bedroom, detached new-build bungalow in Lincolnshire

Product installed: IVT Greenline HT+ C6 ground source heat pump

Distribution system: Underfloor heating on ground floor

Installation date: Project completed February 2013

In February 2013, Lincolnshire residents Mick and Liz South completed the second of their two new build projects. Having already embraced renewable energy during their first build, the South's were adamant they would once again install a ground source heat pump from Ice Energy Technologies.

What prompted you to investigate ground source heat pumps?
"Before building our first property we had intended to install an oil boiler as we are off the main gas grid. However, as a result of our investigation of renewable energy alternatives, we opted for one of Ice Energy's ground source heat pumps.

"We were so impressed with the heat pump in our other property that for this build we only ever considered another ground source heat pump from Ice Energy."

How did you find the installation process?
"The installation process was very straightforward as we chose our builder because he had previously installed Ice Energy ground source heat pumps as well as the one in our other property.

"Work started on the 2 x 38 metre trenches which house our "Slinky" ground loop in October 2012. These trenches contain approximately 150 metres of pipework.

"We haven't boxed in the pipes around the heat pump as yet as they are a talking point for our visitors.

"As with our other property, as part of the build we also installed underfloor heating."

What has it been like living with heat pumps?
"The heat pump system runs itself and is clean, quiet and efficient.

"We are confident that based on our experience of heat pumps in our other property, we will be equally as pleased with the performance of the heat pump installed in the bungalow."

What would you say are the benefits of ground source heat pumps?
"As we see them, the benefits of ground source heat pumps are the relatively low heating bills, the low maintenance of the system and the comfortable internal room temperatures.

"The heat pump within our property provides a good supply of hot water and even with 6 adults living there, the tank can supply enough hot water for 6 continuous showers."

What impact has your heat pump had on your running costs?
"With the property only completed in February of 2013 it's clearly too early to see any cost savings at this stage. That said, our other property which runs completely on electricity costs around £91 per month (averaged across the year) so we estimate monthly costs of around £50."

Why did you choose Ice Energy as your ground source heat pump provider?
"It was simple; we were so impressed with the heat pump in our other property, we only considered a ground source heat pump from Ice Energy for this project."

What has the service been like from Ice Energy and would you recommend them to others?
"From quote to commissioning we have been happy with the good service we have received from Ice Energy with delivery of all parts received on time.

"We would definitely recommend ground source heat pumps and Ice Energy to others."
