In August 2013, David and Christine Brook installed an air source heat pump and matched Ice Energy underfloor heating system as part of a project to modernise and extend their 1960's bungalow. Read on to learn of their experiences.

What prompted you to investigate air source heat pumps?
"We were looking to modernise and extend a dilapidated bungalow which was originally built in 1967 and had not been upgraded since.

"The bungalow had previously been heated with night storage heaters and an open coal fire. It is off the gas grid and has restrictions for oil and biomass delivery so air source heat pumps seemed an obvious economical solution."

How did you find the installation process?
"The installation process from beginning to end took three weeks and was very straight forward. We had an 8.5kW Mitsubishi Ecodan air source heat pump and a matched Ice Energy underfloor heating system installed as part of our renovation and modernisation works."

What has it been like living with an air source heat pump?
"It has been 'switch on and forget' since commissioning. The heat timer is on 24 hours a day and the individual thermostats maintain the house at the desired temperature. The hot water is heated on a timed setting. The heat pump is working well - even our plumber who has never seen one in operation before declared "I have seen the future, this system is fantastic!"."

What would you say are the benefits of air source heat pumps?
"Excellent cost savings, no annual maintenance to arrange - simple is best!"

What impact has your air source heat pump had on running costs?
"The full year electricity bill for heating and hot water has reduced by £300 from 2012-2013 to the same period 2013-2014.

Have you applied to receive Renewable Heat Incentive (RHI) payments?
"I am just in the process of applying for Renewable Heat Incentive (RHI) payments and have found the process to be very straight forward and I anticipate the payments will match information so far received."

Why did you choose Ice Energy as your air source heat pump provider?
"When we set off on the path of renovating our bungalow our first choice was gas because that was what we were used to. However, I researched the systems in great detail and obtained quotations from six companies. I decided on Ice Energy having met staff at the Homebuilding & Renovating Show and was impressed by the knowledge and help they were able to provide. The price offered was also competitive."

What has the service been like from Ice Energy and would you recommend them to others?
"From initial contact with the sales team to the underfloor heating team and the after sales team at the end, everyone has been helpful and knowledgeable, guiding us through the whole process. The service has been excellent and I would have no hesitation in recommending Ice Energy.

"Well done and thank you all."
