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 much noise do air source heat pumps generate?
Most modern air source heat pumps are fairly quiet. The noisy part is the air handling unit, which makes a similar level of noise as an air-conditioning unit. The heat pump itself, which is often installed inside, makes a noise too, but this is typically no more than the noise of a fridge.
How much space do I need for my air source heat pump?
This will depend on the make and model of the heat pump. The air handling unit component of the pump will need to be fitted in a location where air can circulate freely, so typically on an outside wall. Typically the air handling unit will be similar in size to a kitchen appliance, such as a washing machine or dishwasher. You will also need space inside your house for the heat pump itself.
Can I heat my swimming Pool with an air source heat pump?
Air source heat pumps are ideal for pools. Note that for existing swimming pools the current heat exchanger would need to be changed.
How many air source heat pumps would I need for a large building?
This depends on the model that you choose, however if you home is well insulated you will need fewer heat pumps to maintain the same temperature level. Your installer will be able to advise you on exactly how many you will need.
