Costs, savings and maintenance

The costs for fitting a typical domestic system range from £6,000 to £10,000 including installation. Running costs vary depending the size of your home and how well insulated it is. Currently you can get a one off payment of £850 from the government through the RHPP scheme to contribute to your installation costs.

Costs & Maintenance

Heat pumps typically come with a 10 year warranty and should be expected to run for at least 20 years. You should check your system every year and arrange to have a professional installer inspect it every 3-5 years.

Heat pumps need electricity to run the fan and pump, but the heat they extract from the air is more than the energy that they use to capture it.

You should leave your heat pump on all the time during the winter as this will make it much more efficient at capturing heat.

Savings

In the right home the savings can be considerable. The Energy Saving Trust estimates that when replacing an existing electric heating system in a 3 bed semi detached home you could save up to £610 per year, even before any contribution from the Renewable Heat Incentive.

FAQs

How long do air source heat pumps last?
Air source heat pumps are typically designed to operate for at least 20 years.
Do air source heat pumps require any maintenance?
Typically no annual maintenance is required, but there may some makes and models that do require some checks to be carried out.
Do air source heat pumps come with a warranty?
Most air source heat pump installations include warranties for parts and labour. You should check your quote or the pump's product details to find out how long that model's warranty is.
Where in my house should an air source heat pump be installed?
The bulkiest component of an air source heat pump is the air handling unit, which must be fitted outside. The unit can be fitted on an outside wall, but some designs allow this to be fitted some way away from the home, as far as 20-30 meters. The heat pump needs to be in or on the house and typically this is where the essential components are housed.
