What prompted you to investigate heat pumps?
"We had heated our old bungalow with an LPG Rayburn cooker / boiler but when we decided to knock down the property and build the new cottage we looked at heat pumps mainly due to rising energy prices."

How did you find the installation process?
"It took approximately two weeks plumbing work during the time from demolition to completion and was a painless exercise thanks to an excellent builder and plumber.

"A 'Slinky' system of pipework was buried in two diverging trenches, each 38 metres in length."

What has it been like living with heat pumps?
"Our tenants are delighted with the trouble-free performance, particularly during the coldest winter experienced for years."

What would you say are the benefits of heat pumps?
"I would say the considerable cost savings, peace of mind, comfort and less maintenance required in relation to heat pumps.

"As far as we can establish, after 9 months from completion and 6 months from letting, the annual cost of electricity will not exceed £2,000 whilst the PV panels will generate not less than £600 tax free showing a 7.5% return on the cost.

"This is my best ever investment = 12.5% before tax."

Why did you choose Ice Energy as your heat pump provider?
"Ice Energy and their heat pumps were recommended to us by Scandia-Hus and we received good advice from our builder."

What has the service been like from Ice Energy?
"The service from Ice Energy has been very helpful when I've needed it."

Would you recommend Ice Energy to others?
"Yes definitely."
