Frequently Asked Questions

You trust your fridge right? An air source heat pump is very similar. It splits the ambient temperature air into cold air and hot air, expelling the cold air and using the hot air to warm the liquid circulating your radiators/underfloor heating, just like a conventional gas or oil system would.

Technically speaking, the outside air is blown over a network of tubes filled with a refrigerant. This warms up the refrigerant and it turns from a liquid into a gas. The refrigerant transfers its heat to water, making it warm. This warm water is sent around your radiators or underfloor heating.

Comparable with a boiler replacement thanks to the Boiler Upgrade Scheme. Every installation we do is bespoke and tailored to your home, making there no one price. That said, installations start from £1,500. For a typical UK 3 bedroom house built in the last 60 years, the cost of the heat pump ranges from £1,500 to £3,000. Installation costs can vary depending on accessibility, the size of the house, the existing plumbing and your location. It’s best to get in touch with our heat pump architects to discuss pricing in more detail.

Air source heat pumps normally have a life span of 20 years or more if they’re well looked after and serviced regularly, making the heat pump an excellent choice for a long term heating option for the home. As they’re designed to process air rather than a physical substance such as fuel or water, a heat pump can be more reliable than boilers and oil heaters.

Once installed, an air source heat pump is very easy to maintain, however, it will need attention on a regular basis, just like your boiler did. Annual services are a requirement of most manufacturers to maintain their warranty. Checks between 2 to 4 months are recommended in order to prolong the life of the heat pump, services are recommended annually to get ahead of any issue and maintain the heating efficiency of the unit.

We will be able to advise in minutes if your home is eligible for the Boiler Upgrade Scheme, giving you a £7,500 discount. There’s also 0% VAT to pay right now. It’s rare to find a home that can’t become eligible, if they aren’t already. Qualification isn’t based on income or your status, it’s the home.

Air conditioning units and air-to-air heat pumps may seem similar, but they serve different primary functions. Air conditioning units are designed specifically for cooling only. On the other hand, air-to-air heat pumps are more versatile as they can provide both cooling and heating. In the summer months, they work like traditional air conditioners, in cooler months they extract heat from the outside air and transferring it inside to warm the house.

This dual functionality makes air-to-air heat pumps a more comprehensive solution, likely why they’re the more popular of the two. Air to air heat pumps are often more energy-efficient than traditional air conditioning systems

Got a 5kw solar and 8kwh battery system installed by Cahill and had a great experience from start to finish. Would 100% recommend them. Customer service was top notch and the installation was quick and straightforward. They made it easy and while it’s still early days, it’s good to see how much you’re generating and saving with the metrics in the app. 5 star!

Cahill Renewables installed my solar and battery solution November 2023. They have been incredibly professional and prompt at every stage from initial enquiry, installation and after care service. They were so efficient with the paperwork, which enabled me to be exporting back to the grid within 4 weeks. I am really enjoying being a solar power user.

We chose Cahill Renewables to fit our Heat Exchanger as of all the people we talked to, they were by far the most professional in their attitude, explaining exactly what we would need. The team who came to fit it were there on time and got straight to work. They made a very neat job under quite difficult circumstances as we have a small bungalow with not much room to move anything about. Apart from providing coffee and tea we didn’t have to lift a finger, for which, now getting on in years, we were very grateful. They made an extremely neat job running the pipes under the house, so, no ugly fittings running along skirting boards, although of course this made the job harder for them it was their idea and we were extremely grateful. The whole service from beginning to end was extremely professional. We wouldn’t hesitate to recommend Cahill Renewables in the future.

Having decided to have solar panels installed Cahill Renewables were one of five companies we approached for a quote. Right from the start we were impressed with their response, their efficiency and willingness to listen to what we wanted and to answer all the questions we had. The quote we received was competitive and having agreed a date and timescale for the work it all went ahead as planned. All of the guys who came on site were polite, considerate, careful and professional. They worked extremely well as a team to ensure the job was completed in a timely manner and kept the site clean and tidy. We enquired about having some additional electrical work done linked to the solar installation and this was scheduled to fit in with the existing work whilst they were on site. We have no hesitation in recommending Cahill Renewables to others. A great team in all respects.

Cahill Renewables have been absolutely great installing our home solar system. They have been incredibly helpful from the initial quote, interpreting our needs to provide the final quote, installing all the panels and battery and then patiently explaining how the Tesla battery system works. A very helpful and competent team which we throughly recommend.

Ended up not going ahead due to technicalities and planning permission requirements on my specific situation, but cahill renewables were the ones to go with if I did go ahead. Josh was polite and knowledgeable, got a very fair quote from them for a ASHP install and the quoting process was very pleasant and non pushy.
