Frequently Asked Questions
An air source heat pump absorbs heat from the air outside into a fluid. This is fed through a compressor to increase its temperature, and transferred to the indoor heating and hot water distribution network. Essentially, air source heat pumps work like a refrigerator in reverse. The outside fan unit is usually positioned on an external wall.
Air source heat pump installations usually cost between £7,500 and £12,500, depending on the size and power of the heat pump, how much hot water storage you require and whether you want the heat pump to have additional features, such as remote web-connected control. Existing properties might need insulation upgrades to meet Ofgem RHI regulations, which would of course add to the overall cost of a project. But for the air source heat pump purchase and installation alone, the above cost estimate is usually accurate.
Heat pumps require a bit more space than a traditional wall-hung boiler system. The hot water cylinder is often located next to the system, rather than elsewhere in an airing cupboard. It’s important to plan a dedicated area (plant room) for the equipment. Possible solutions for a plant room are utility rooms, garages, basements, or possibly a detached outbuilding.
For the fan unit itself, you need adequate space on the outside of an external wall. This must be free from nearby obstacles and be located at least one metre from the property boundary (as per official planning rules). The size of the box depends on the size of the system and the manufacturer. However, most domestic air source heat pump units don’t exceed 1 x 1.5 metres, and are less than 0.5 metres in depth. Speak to one of our advisors about your options.
Running costs depend on the size of the property and system. The typical UK home requires about 12,000 kW of heat annually. An air source heat pump may create 3 kW of heat for each 1 kW of electricity it consumes. As a result, it will use 4,000 kW to fulfil the demand. As a rough example, with electricity priced at £0.14* per unit, annual running costs will be £560.
This is by no means a hard and fast rule. If you also get electricity from your own renewable source, such as a solar PV installation, the running costs can be reduced. Speak to one of our experts for more clarity about your savings from an air source heat pump.
*Electricity Prices can vary by region and by supplier and tariff. You should check with your supplier the best available tariff for you.
Yes, but radiators must be adequately-sized. Air source heat pumps work best with underfloor heating, because of the ability to deliver constant low-grade heat. Underfloor heating will work well with flow temperatures as low as 35 degrees celsius. However, if your radiators are large enough to cater for a low flow temperature, they will be suitable for your air source heat pump.
Some clients have underfloor heating on the lower floors, and large radiators on upper floors of the property. It’s about ensuring that you have the right heat distribution system in place to benefit from the efficient operation of an air source heat pump. Contact us for more information.
Air source heat pumps don’t usually need planning permission. They are considered in England, Wales, and Scotland to be a permitted development. However, this changes if the property is listed, or if the property is in a protected area. It doesn’t mean that it’s impossible, but you will need to check with the local authorities to see what can be done.
Air source heat pumps are between 200% and 400% efficient. This means they produce 2-4 times the amount of heat compared to the energy they use. This might change slightly during colder months, but the heat pump will still be able to power heating and hot water efficiently.
