Air Source Heat Pumps

Heat pumps are riding an increasing wave of popularity because of their high efficiency and low running costs. Compared to a gas boiler that can be over 90% efficient, heat pumps can achieve 400% meaning a huge reduction in running costs. Unlike fossil fuel boilers, air source heat pumps can generate hot water and heating 24/7 by compensating for changing weather conditions. Using weather compensation, ASHP's can also maintain a stable comfort level all year round automatically, whatever the weather.

The biggest feedback we get from clients who have installed air source heat pumps, is the comfort level and ease of use that they provide. With the installation of our first heat pump in 2003 we are very proud of our status as a leading installer of heat pumps in Yorkshire.

What are Air Source Heat Pumps

Your air source heat pump will draw in air and pass it over a series of refrigerant filled tubes. This raises the temperature and turns the refrigerant into a gas before sending it on to a compressor. Within the compressor of your heat pump, this is converted back into a liquid which raises the temperature further. This heat is then transferred to water through a heat exchanger which is the final step before the newly heated water circulates throughout your home.

The only cost you'll incur once the system is installed is the electricity needed to run the compressor and pump system, but the heat generated is up to 300% more than the electricity used - for each kWh of electricity used, you'll received up to 4kWh in heat. Some steps in this process might sound overly complicated, yet a similar (but reverse) system has been extracting heat and keeping your fridges cold for decades!

What other people think

5 Stars

I have used Warmaway for a number of jobs (installing boilers, underfloor heating, refitting a bathroom and various maintenance items) over a few years and they are always professional, reliable and very committed to completing to a high standard - highly recommended

5 Stars

New boiler installed and removal of old one and Mains 7 water heater. Work was completed in less than 2 days, the engineers were really friendly, courteous and clean. They explained what they were doing as they went along and installed a new Nest thermostat. They helped me install the app onto my phone and then paired it to the thermostat for me. I would definitely recommend them and use again. Excellent service.

5 Stars

Warmaway installed an Air Source Heat Pump and several new radiators for us in February 2021. Everything about the process was professional courteous and efficient. The quote was clear and competitive and everything was explained about the system and the installation. We were kept informed at every stage and knew when to expect the team to come and work. All the team on site were extremely polite, tidy and hardworking. We had a courtesy follow-up visit just to check we were happy with the system and tweak any settings. I recommend Warmaway to anyone who enquires about our new ASHP.

5 Stars

A fantastic service from start to finish. No nonsense advice, turned up when they said they would, cleaned up after themselves and were thoroughly nice people. We had a ground-source heat pump installed with some extra radiators inside. Any snags were fixed very quickly and cheerfully. Ongoing advice by phone or email is never too much trouble. I can't reccommend them highly enough and have encouraged several of my friends to use them - which they have with great results. Please can we have more companies like Warmaway in the world?
