Are air source heat pumps worth it?

Yes, air source heat pumps are worth it for most UK homeowners and businesses. They offer long-term savings, work efficiently even in colder weather, and are supported by government grants like the Boiler Upgrade Scheme. While the upfront cost can be higher than a new boiler, the ongoing savings on your energy bills and reduced carbon emissions make them a smart investment.

How do air source heat pumps work?

Air source heat pumps work by extracting heat from the outside air and using it to warm your home – even when it’s cold outside.

Here’s how they work:

  • A fan extracts air from outside your home.
  • The air passes over a refrigerant that absorbs the heat.
  • The refrigerant is compressed to increase the temperature.
  • That heat is transferred into your home’s radiators, underfloor heating or hot water cylinder.

It’s a clean, low-carbon process – and because it moves heat rather than generates it, it’s much more energy efficient than a gas boiler.

What’s involved in an air source heat pump installation?

Here’s what’s typically involved in an air source heat pump installation:

1. Survey by a certified ASHP installer

Your air source heat pump installer checks your home’s layout, current heating system, insulation, and heating needs to recommend the best setup.

2. Fitting the outdoor unit

This unit is slightly larger than a standard washing machine. It draws in air and is usually placed at ground level with good ventilation space.

3. Connecting to your heating system

Your local air source heat pump installer will connect the unit to your radiators, hot water tank, or underfloor system.

4. Setting up wiring and smart controls

The system is connected to your electricity supply and set up with any smart heating controls you’ve chosen.

5. Testing and final checks

Your air source heat pump installer will test everything to make sure it’s working properly before explaining how it works and handing the system over.

Heat Pump Installation Process

How much does an air source heat pump installation cost?

FAQs

You must have a few questions. We’ve answered some of the most commonly-asked questions about air source heat pumps here, but please speak to the team if you have any more.

Are air source heat pumps cheaper to run than a gas boiler?

Yes, air source heat pumps are typically cheaper to run than gas boilers over time. While electricity is more expensive than gas per unit, heat pumps are much more efficient – producing up to 3 units of heat for every 1 unit of electricity used. This means lower energy bills, especially in well-insulated homes.

Are there any government incentives or rebates for installing air source heat pumps?

Yes, homeowners in the UK can apply for government incentives like the Boiler Upgrade Scheme, which offers grants of up to £7,500 towards installation. Some may also qualify for support through the ECO4 scheme or local authority funding, though eligibility criteria for this is far stricter.

What is the installation process for an air source heat pump?

Installing an air source heat pump involves a home survey, fitting the outdoor unit, connecting it to your heating and hot water system, and electrical setup. Once installed, the system is tested and handed over. The process is usually completed within 3 to 5 days by certified air source heat pump installers.

What maintenance is needed for an air source heat pump?

Air source heat pumps need very little maintenance. It’s recommended to:

  • Check the outdoor unit for leaves or debris
  • Clean filters if needed
  • Book an annual service with a qualified engineer

Most systems last 15–20 years with regular checks.

How long does it take to install an air source heat pump?

An air source heat pump typically takes 3 to 5 days to install, depending on the size of the property and whether any upgrades to your radiators or hot water system are needed.

Which houses are suitable for air source heat pumps?

Most UK homes can use an air source heat pump, including detached, semi-detached, and terraced properties. Homes with good insulation will see the biggest benefits. Older homes may need upgrades like better insulation or larger radiators for the most efficiency.

How much space will an air source heat pump take up?

The outdoor unit is roughly the same size as a regular washing machine and is usually placed at ground level outside. You may also need space indoors for a hot water cylinder and any additional equipment, depending on the system type.

Do air source heat pumps work in winter?

Yes, air source heat pumps work efficiently in winter – even in temperatures as low as -15°C. They extract heat from the outside air and use it to warm your home no matter the weather, though proper insulation helps maintain the system’s efficiency.

Are air source heat pumps noisy?

No, modern air source heat pumps are quiet, typically producing around 40–60 decibels – similar to a standard fridge. The outdoor unit is designed to run with minimal noise, and indoor components are usually near-silent.

Do air source heat pumps work well in older homes?

Yes, but older homes may need upgrades like improved insulation or larger radiators to get the most from an air source heat pump. With the right setup, they can work just as effectively in period properties as they do in new builds.
