The technology has significantly improved over time and many of current generation heat pumps are designed to operate in extremely cold weather and at temperatures as low as – 25C.
Find your rates
Many energy suppliers are offering electricity tariffs that are tailored for heat pumps, significantly cheaper during off peak times and hence make operation of heat pump cheaper than a typical gas boiler.
Air Source Heat Pump Sourcing Guide
What is an Air Source Heat Pump?
An air source heat pump is a heating and cooling system that draws heat from the outside air and transfers it indoors for warmth and comfort. It serves as an energy-efficient alternative to conventional heating systems such as boilers or electric heaters.
How Does an Air Source Heat Pump Work?
Utilizing the reverse Carnot cycle, the refrigerant in the evaporator absorbs significant energy from the air. This energy is then compressed into a high-temperature, high-pressure gas by the compressor, and heat is exchanged through the heat exchanger to provide heating and hot water for the home.
Air Source Heat Pump Installation System
Essentially, the air source heat pump is installed outdoors in a central location and connected to the water tank, heat pump kit, and buffer tank, which are linked to multiple fan coils.

FAQs about the Air Heat Pump & Boiler Upgrade Scheme
What is a heat pump, and how does it work?
What types of heat pumps are available?
Air Source Heat Pumps (ASHP): Extract heat from the outside air, effective even in low temperatures.
Ground Source Heat Pumps (GSHP): Use underground heat, often with a ground loop installed, and are efficient in all seasons.
Water Source Heat Pumps: Suitable for properties near a water source, these pumps draw heat from water bodies.
What is the Boiler Upgrade Scheme?
What types of heating systems qualify for grants under the scheme?
How energy-efficient are heat pumps?
What are the benefits of installing a heat pump?
Are there government incentives for heat pump installations?
Who is eligible for the Boiler Upgrade Scheme?
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.
How do I apply for the scheme?
- 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.
Can new-build properties apply?
- 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
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.
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

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.
