Air Source Heat Pump | FAQs
Is a heat pump just a replacement for a boiler?
No. An air source heat pump should not be treated as a simple like-for-like boiler replacement. To perform properly, it needs to be considered in the context of the whole property and wider heating system.
How long does an air source heat pump last?
Lifespan can vary depending on the system, the installation and how well it is maintained over time. Regular servicing helps support long-term performance.
Do air source heat pumps need servicing?
Yes, regular servicing is important to help protect performance, efficiency and long-term confidence in the system.
Will I need to change anything else in the house?
Some properties may need changes to parts of the wider heating system, such as emitters, controls or hot water arrangements. That does not apply in every case, which is why each property should be assessed on its own merits.
How long does installation take?
This depends on the property and the scope of work involved. A straightforward installation may be completed relatively quickly, while other projects may require more time depending on system changes and site conditions.
Is grant support available?
Grant support may be available for eligible properties. We have a separate page covering the Boiler Upgrade Scheme in more detail.
How much does an air source heat pump cost?
The cost depends on the property, the heating system and the work required. Some installations are more straightforward than others, which is why a proper survey is the best way to understand likely costs.
Do they work in cold weather?
Yes, modern air source heat pumps are designed to operate in low outdoor temperatures. As with any heating system, performance depends on correct system design and installation.
Are air source heat pumps noisy?
A properly selected and correctly installed system should not be intrusive in normal use. Positioning, product choice and installation quality all play a part.
Do air source heat pumps provide hot water?
Yes, air source heat pumps can provide both space heating and hot water when designed as part of the overall system.
Do heat pumps work with radiators?
They can do, but this depends on the existing system and whether the radiators are suitable for the way the heat pump will operate. This is one of the reasons why proper assessment matters.
Do air source heat pumps work in older properties?
Yes, many older properties can be suitable, but they often need a more considered review of heat loss, insulation levels, emitters and the wider heating setup before the right recommendation can be made.
Are air source heat pumps suitable for all homes?
Not every property is the same, which is why suitability should always be assessed properly. Many homes can be suitable for an air source heat pump, but the right approach depends on the property, the existing heating system and what you want to achieve.
What is an air source heat pump?
An air source heat pump is a heating system that extracts heat from the outside air and uses it to provide heating and hot water for a property.
