Air source heat pumps explained

What is an Air Source Heat Pump?

An air source heat pump is a heating and hot water system that draws warmth from the outside air and transfers it into your home. It's an energy-efficient alternative to a gas boiler or electric heating and it works even when it's cold outside.

How does it work?

A refrigerant in the heat pump absorbs heat from the outside air. A compressor raises that heat to a higher temperature, and a heat exchanger transfers it to your home's heating system and hot water cylinder. Because it moves existing heat rather than burning fuel, it delivers far more energy than it consumes.

How is it installed?

The heat pump unit sits outside your home in a suitable spot and connects to your hot water cylinder and, where needed, a buffer tank. From there it feeds your radiators or underfloor heating. Our engineers handle the full installation and talk you through how to get the best from your system.

FAQs about the Air Heat Pump & Boiler Upgrade Scheme

A heat pump transfers heat from outside sources (air, water, or ground) into your home, providing energy-efficient heating and cooling. Unlike conventional boilers, heat pumps don’t burn fuel; they use electricity to move heat, making them more eco-friendly.
  • Air source heat pump: £7,500 towards installation.
  • Ground source heat pump (including water source): £7,500 towards installation.
  • Biomass boiler: £5,000 towards installation.

A temporary uplift to £9,000 is available from 21 July 2026 for eligible off-gas-grid homes that rely on heating oil or LPG. Most gas-heated homes remain on the £7,500 grant. Installations also qualify for 0% VAT.

How efficient are heat pumps? Very. Heat pumps typically reach 300–400% efficiency (a COP of 3–4), meaning they produce three to four units of heat for every unit of electricity used.

What are the benefits of a heat pump? Lower energy bills compared with fossil-fuel heating, reduced carbon emissions, and a long service life — typically 15–20 years with proper maintenance.

The Boiler Upgrade Scheme (BUS) is a UK government initiative providing grants to homeowners to support the installation of energy-efficient heating systems, like heat pumps and biomass boilers, in homes and non-domestic properties.
Air Source Heat Pumps (ASHP): £7,500 towards installation. Ground Source Heat Pumps (GSHP): £7,500 towards installation, including water source heat pumps. Biomass Boilers: £5,000 towards installation.
Heat pumps are highly efficient, often reaching 300-400% efficiency (COP rating of 3-4). This means they produce three to four units of heat for every unit of electricity consumed.
Energy Savings: Heat pumps reduce energy bills compared to fossil-fuel heating systems. Eco-friendly: Reduced CO₂ emissions contribute to a greener footprint. Long Lifespan: Heat pumps last 15-20 years on average with proper maintenance
Yes, in the UK, the Boiler Upgrade Scheme (BUS) offers grants of up to £7,500 for installing heat pumps. Other countries also have incentives; check with local energy authorities for available programs.

Eligible applicants include:

  • Property owners in England and Wales.
  • Properties with existing fossil fuel systems like oil, gas, or LPG.
  • Homes or buildings replacing an old system with a new heat pump or biomass boiler.
  • Non-new-build properties (excluding properties still under construction by developers).
  • Some self-build properties with owner-built or commissioned constructions.
  • Choose a certified installer: The installer applies for the scheme on your behalf.
  • The installer handles most of the paperwork, liaising with Ofgem to approve the application.
  • After installation, the grant amount is deducted from your final bill.
  • New builds still under developer ownership aren’t eligible.
  • Finished new builds with existing fossil fuel systems may qualify for heat pump upgrades.

Note

    • A typical customer can save £164 per year versus the current single-rate price cap tariff. This is based on the following; Savings are based on a customer using Ofgem’s typical domestic consumption of 2700 kWh electricity and with heating provided by an ASHP with COP of 3.1 providing equivalent heat to that from a 94% gas boiler using 11,500 kWh of gas.
    • We’re giving customers who install an Ideal heat pump free electricity for the whole of December 2025 which amounts to £200. This saving is based on a heat pump usage of 541 kWh, 23% off-peak consumption, 2,700 kWh Ofgem average annual electricity usage, average December usage 10.1% and based on Standard Variable tariff rates that apply from 1 October 2024 to 31 December 2024.
    • As of October 2024, Ideal Heating is offering seven years of free service, maintenance and warranty, which is worth £1,150.  This is made up of the market value of 4 services (4 x £225 = £900) plus the market value of the extended warranty (£250).£1,150 + £164 + 200 = £1,514
  1. We’re giving customers who install an Ideal heat pump free electricity for the whole of December 2025, saving you approximately £200 (usage and savings may vary). This saving is based on a heat pump usage of 541 kWh, 23% off-peak consumption, 2,700 kWh Ofgem average annual electricity usage, average December usage 10.1% and based on Standard Variable tariff rates that apply from 1 October 2024 to 31 December 2024.

  2. This includes 4 in-person services and 3 remote services. If a remote survey flags anything concerning, Ideal Heating will perform an in-person service free of charge.

    As of October 2024:

    Market value of in-person services = 4 x £225 = £900

    Market value of extended warranty = £250

    Total value = £1,150

  3. A typical customer can save £164 per year versus the current single-rate price cap tariff. This is based on the following; Savings are based on a customer using Ofgem’s typical domestic consumption of 2700 kWh electricity and with heating provided by an ASHP with COP of 3.1 providing equivalent heat to that from a 94% gas boiler using 11,500 kWh of gas.

  5. Air source heat pump carbon savings

    6 tonnes x 2.36 residents = 14.16 tonnes per household

    1.8 tonnes / 14.16 tonnes = 0.134

    = 13.4% reduction in CO2 emissions

    • The 1.9-tonne reduction in carbon footprint is based on switching from an A-rated gas boiler to a standard air source heat pump in an average, three-bedroom semi-detached home in England, Scotland, or Wales, with radiator upgrades. Source: Energy Saving Trust 
    • According to ONS reports, average CO2 emissions are 6 tonnes per head,and the average household size is 2.36 residents. Therefore, an average household has a carbon footprint of 14.16 tonnes per year.
    • This equates to a 13.4% reduction in CO2 emissions if you upgrade your old gas boiler with an air source heat pump.
    • According to the BA carbon calculator, a British Airways return flight in economy class from London Heathrow Airport to Perth International Airport (Australia) emits around 1.826 tonnes of CO2 over 29,016km.
