Air source heat pumps: How it works
With an air source heat pump, no fossil fuels are burned, and the energy that’s produced is 100% renewable. The way they work is surprisingly simple:
- An outdoor unit draws in heat from the outside, even when it’s cold
- The heat is then transferred to a refrigerant, which is compressed and heated up
- The hot refrigerant is then used to heat water or air inside your home
- The refrigerant then cools down and returns to the outdoor unit, where the cycle begins again

FAQs
You must have a few questions. We’ve answered some of the most commonly-asked questions about air source heat pumps here, but please speak to the team if you have any more.
What are the disadvantages of an air source heat pump?
Like all heating options, air pumps do have a few disadvantages, including the high upfront cost, being less efficient in cold weather, and needing regular maintenance. However, their long-term financial and environmental advantages far outweigh the disadvantages, so speak to us if you’re in any doubt about their suitability for your home.
Is an air source heat pump expensive to run?
This is dependent on a number of factors, including the size of your home, the climate you live in, and the efficiency of the heat pump. However, in general, air source heat pumps are not expensive to run. The cost could potentially be driven down even further with the addition of a solar energy installation, which would allow you to become completely self-sufficient away from the National Grid.
Are air source heat pumps a good investment?
Before deciding whether to go ahead with an air pump heat installation, you’ll need to consider your budget, the cost of installation, the efficiency of the heat pump, the climate you live in, the size of your home, and the cost of your current energy bills. We highly recommend speaking to our expert team before you make a final decision. We pride ourselves on our impartiality and will only recommend a solution that will benefit you and your family.
Why is my electric bill so high with an air source heat pump?
Heat pumps are generally inexpensive to run, so if your electricity bills are high, you might want to check that the pump is the right size for your home. It could also be that it hasn’t been properly installed or maintained, the climate is too cold, or the insulation in your home is poor. We’ve specialised in installing insulation for over 50 years, so get in touch if you think we can help your air pump run more effectively.
Are air source heat pumps cheaper to run than a gas boiler?
According to the Energy Saving Trust, the running costs of an air source heat pump are typically around 20%-50% lower than the running costs of a gas boiler. This is because they are more efficient at extracting heat from the air than gas boilers.
Should I replace my gas boiler with a heat pump?
Heat pumps can be a good investment if you’re looking to save money on your energy bills, reduce your carbon footprint, and futureproof your heating source. However, they are a big investment, and other alternatives, such as A-rated gas boilers and hydrogen boilers, are available. Speak to us before making any decision, and we’ll give you an honest answer.
Do I need a boiler if I have a heat pump?
This usually depends on the climate you live in and the efficiency of your heat pump. For example, if you live in a cold climate and your heat pump is not very efficient, you may need to keep your boiler as a backup for hot water.
Are heat pumps cheaper to run than a combi boiler?
In almost all cases, air source heat pumps are cheaper to run and more energy efficient than their combi boiler counterparts. If you need a comparison for your home, give us a call or complete the callback form here
