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

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.

It's not every day you have a solar PV system put in, so you want it doing right, from the word 'go.' Cahill's did that, and kept on giving outstanding service long after the work was done, the bill was paid, and the kit was powering our whole house. Cahill's went to great lengths to make sure we didn't just get what we wanted but also what we needed, including arranging the DNO authorisations for feed-in. They were open about what the system could and couldn't (and wouldn't) do, and about what it would (and does) provide. Their staff are no-nonsense, human, and straight-talking; technicians courteous and effective; contractors knowledgeable and efficient. Couldn't ask for more.
