Heat Pump Case Studies: Ground Source Heat Pump Replacing Oil

Property type: 6 year old, 4-bedroom detached dormer bungalow in North Yorkshire

Product installed: C9M HT Plus ground source heat pump, 2 x 75m deep boreholes

Distribution system: Radiators

Installation date: June 2010

Cost savings: Approximately £1,500 per annum

In June 2010 North Yorkshire resident Melvyn Dorman replaced his oil boiler with a ground source heat pump from Ice Energy. Accessing stored solar heat via two boreholes, Professor Dorman's heat pump has provided significant savings compared to his previous heating system.

What prompted you to investigate heat pumps?
"We wanted to reduce / eliminate our dependency on oil (there is no gas in our village) and save expenditure in the long term.

"Having worked in Germany I was fully aware of the potential benefits of this system but we had to wait for quite some years before the government of the day decided that this technology might help it meet the EU targets which had been signed up to without much advance strategic planning."

How did you find the installation process?
"The installation process was slow and steady and we were ready to be patient about our drive being out of action. All in all the process took two months from the first drilling of the two boreholes which run to a depth of 75 metres, to completion."

"The heat from our ground source heat pump is distributed via radiators."

What has it been like living with heat pumps?
"Perfect. The heat pump performs as advertised: whatever the season our home is comfortable all year around. The external and internal thermostats produce the required temperature all year round - and we are never short of hot water.

"We are saving costs, have a level of comfort throughout the year undreamed of, peace of mind and virtually no maintenance."

What impact has the heat pump had on running costs?
"I have been saving approximately £1,500 per annum since installing my heat pump (I calculated this figure when oil was 15% lower than current prices).

Why did you choose Ice Energy as your heat pump provider?
"Our architect had helped the purchaser of one of her designs to decide on a heat pump system. We decided to investigate the feasibility of a retrofit install and then chose to contact Ice Energy who had installed his heat pump."

What has the service been like from Ice Energy and would you recommend them to others?
"The service from Ice Energy has been very good and I would recommend them to others. Within our village hall we have sung songs of praise for our extremely efficient system. As a member of the Village Hall Committee I have even circulated to interested neighbours the data I have accumulated over the past 3 years."
