What is an Air Source Heat Pump?

Air Source Heat Pumps extract heat from the outside air to heat your home and water, even when temperatures drop as low as -15°C. They work by transferring natural heat energy from the air into your heating system – a greener alternative to traditional boilers.

Why choose Air Source Heat Pumps?

Pros

Cons

Frequently Asked Questions

How much is an air source heat pump​?
The cost of an air source heat pump varies depending on the size of the system and the property, but typically ranges between £7,000 and £14,000, including installation. However, government grants like the Boiler Upgrade Scheme can provide up to £7,500 towards the cost, making it more affordable.
Are air source heat pumps noisy?
Air source heat pumps do produce some noise, but modern models are designed to be relatively quiet. The sound mainly comes from the fan and compressor, typically ranging between 40-60 decibels—similar to a refrigerator or a quiet conversation. Proper installation and placement can help minimise any noise impact.
Are air source heat pumps expensive to run​?
Air source heat pumps are generally cheaper to run than oil or electric heating but may have higher running costs than gas boilers, depending on electricity prices. They are highly efficient, generating up to 4kW of heat for every 1kW of electricity used, which helps reduce overall energy bills, especially in well-insulated homes. Government incentives can also help offset costs.
How to install air source heat pump​?
To install an air source heat pump, a qualified professional will place the outdoor unit in a well-ventilated area, connect it to your home’s heating system (radiators, underfloor heating, or hot water cylinder), and complete the necessary plumbing and electrical work. The system is then tested and adjusted for efficiency.
Can air source heat pumps cool​?
Yes, some air source heat pumps can provide cooling in addition to heating. This is achieved by reversing the flow of refrigerant, similar to how an air conditioner works. However, not all models have this cooling feature, so it's important to check the specifications before installation.
How much electricity does an air source heat pump use​?
An air source heat pump typically uses about 1kW of electricity to produce 3-4kW of heat, depending on the model and efficiency. The amount of electricity it uses will depend on factors like the size of your home, the system's performance, and the outdoor temperature. Generally, air source heat pumps are much more energy-efficient than traditional electric heating systems.
