Air source heat pumps do make a bit of noise. However, it’s the external unit that makes the noise, minimising disruption in your home. And while it’s a good idea to ensure your external unit isn’t located directly under your bedroom window or very close to a neighbour’s property, it won’t be louder than 40-60 decibels. In many cases, this is actually quieter than a fossil fuel-powered boiler.
Average Air source heat pump cost
How much it will cost you to install an air source heat pump on your property depends on the type of building you have, how powerful your heat pump needs to be, and your location. However, the common price for an air source heat pump installation is about £13,141 your area.

Advantages for Air source heat pump
- They are energy efficient and an air source heat pumps can generate less CO2 than conventional heating systems such as a boiler
- By installed you can qualify for the Renewabl Heat Incentive (RHI). This is a financial incentive that pays you for generating your own heat through owning a heat pump
- Are quite easy to install - definitely easier than a ground source heat pumps, particularly for retrofit (no digging up your garden)
- In some cases you can reuse your existing radiators (if retro fitting) but are ideal for use with underfloor heating
- Low running costs, meaning lower energy bills
Disadvantages for Air source heat pump
- It uses electricity to drive the pump so an air source heat pump is not completely zero-carbon
- They can be a bit noisy - the external unit can be noisy and also blows out colder air to the immediate environment
- You will require enough space in your garden for the external unit (it looks similar to an air-conditioning unit)
- Lower maximum tap water temperature than with traditional heating systems

Air source heat pump FAQs
If you’re planning to install an air source heat pump in your home or property, one of the first questions you’d probably want to ask is, how long does it last? In this post, we aim to provide an answer to this question and more. Let’s take a look!
Generally, heat pumps are considered to be very durable and long lasting. In the previous years, their average life expectancy was at 15 years, however with the advancement in modern technology, the newest units are able to last for about 20 to 25 years before they become due for replacement. The longevity and durability of air source heat pumps is as a result of their design as you won’t find many things that can go wrong and even more so with their latest models. As you would have expected, their lifespan normally varies with the manufacturer as well as model. However, while having them regularly maintained can help to extend their life expectancy and efficiency, they’re not considered to be a necessity.
When compared to other types of heating sources, heat pump comes out on top when it comes to longevity. The significance of this is immense due to the fact that the nature of the RHI scheme is to recoup sufficient funds so that after 7 years, the system will ultimately have costed nothing beyond that of a new boiler depending on the performance. Other heating sources such as oil, gas and electric boilers will only have to work for about 10 to 12 years before their parts will need to be replaced and times the manufacturer may have well stopped producing such parts.
If you look after your air source heat pump, it can last for over 20 years. Make sure you check it every year and get a registered or qualified installer to check it every 3-5 years to prolong its life. If in doubt, check the manufacturer’s maintenance instructions.
Air source heat pumps work by absorbing heat from the outside air and transferring it inside to heat up your property.
An air source heat pump has an outdoor unit containing a refrigerant. This absorbs heat from the air and passes into a compressor, where the temperature is increased. The heat then transfers either into water, which feeds into your wet heating system, or into air, which is dispersed around your property.
Air source heat pumps need electricity to run, but this is to power the compressor rather than directly generate heat.
Are you interested in installing an air source heat pump in your home or property? If yes, then you’d probably want to know just how much this is going to cost. Well, so are many other potential investors in the unit and we aim to answer this question once and for all. In this post, you’re going to discover the price range at which your new air source heat pump will fall in.
As simple as it seems, the cost of an air source heat pump can’t be accurate and straightforward as there are a number of factors that greatly influences the price. These influencing factors include the size of the heat pump, the system’s complexity, your personal preference - whether simple or advanced controls, and lots more. However, according to Energy Saving Trust, an air-to-water heat pump should fall within the range of £7000 to about £11000. What’s more? You’ll also need to put into consideration the cost of upgrading your radiators or fitting underfloor heating which can also cost you thousands of pounds.
In general, the main cost of a heat pump is the upfront cost of making a purchase as well as installing it. The heat pump will consume a little amount of electricity and the running costs are also relatively low. The amount your air source heat pump will cost largely depends on your home’s size, the temperature you want your home or property to be as well as how properly insulated your home is.
The period of time it’ll take to recoup your investment in the system in energy savings will also depend on a wide range of factors including the price you pay for electricity, how efficiently the system works, how you use the heat generated and more.
Whether installing an air source heat pump will help you save money depends on your property, how long you expect to live there, and the type of heat pump you get.
Air source heat pumps are initially quite expensive to install. However, if you get an air-to-water air source heat pump, you’re eligible for money from the Renewable Heat Incentive [https://www.energysavingtrust.org.uk/scotland/grants-loans/renewables/renewable-heat-incentive] (RHI). This is a UK government scheme that gives you quarterly cash payments over seven years if you install an eligible renewable heating technology (air-to-air air source heat pumps aren’t included).
All this means that if you have long-term plans to stay in your property, then an air-to-water air source heat pump can be a great way to save money on your heating bills. However, if you’re planning on moving out of your property relatively soon, or are a considering an air-to-air air source heat pump, it may not be the best financial option for you.
It’s important to remember that air source heat pumps are at their most efficient when installed in very well insulated properties. If your property’s not very energy efficient, you may find that a heat pump won’t help you save money.
No, air source heat pumps aren’t particularly noisy. Most models make about the same amount of noise as a boiler or fridge. And don't forget, the unit itself is fitted to the outside of your property so you won't hear a thing when you're indoors or at nightime!
Air source heat pumps work by taking heat from the air and using it to heat your home. They absorb heat from the air into a fluid, which then goes to a compressor where it gets hotter. This heat is then used to warm up water or air, which is distributed around your home.
First and foremost, you should know that heat pump is simply a device whose primary function is the transmission of thermal energy from one spot to the other. A good example can be found in the refrigerators whereby the evaporation as well as cooling of a liquid is incorporated to lower the storage compartment’s temperature. In recent times, this whole technology is utilized to draw the potential thermal energy present in the air outside and transmit it directly to the home or property where it’s going to be compressed and the heat transferred with the help of a number of coils. This is exactly what an air source heat pump does as it absorbs heat from the air and convert it into a higher temperature using a compressor. How the air source heat pump works is really simple, it’s just like a refrigerator but in reverse. Let’s take a look!
- The air source heat pump extracts heat present in the outside air into a liquid refrigerant at a reduced temperature.
- The pump then compresses the liquid to increase its temperature with the help of electricity. Once done, it then compresses it back to liquid so as to free the heat stored.
- The heat released is then directed to the radiators or under floor heating, while the ones left would be stored in the hot water cylinder.
- The hot water that’s stored can be used for showers, baths as well as taps.
Overall, the air source heat pump is an efficient way to make your home warm. It makes use of electricity to function, but it should consume lower electrical energy than the heat it generates.
