Are Air to Air Heat Pumps Eligible for the Boiler Upgrade Scheme?


Yes, air to air heat pumps are eligible for the Boiler Upgrade Scheme (BUS) in the UK. The BUS provides financial assistance to homeowners, small landlords, and private landlords in England and Wales to help cover the upfront costs of installing air to air source heat pumps. See also: What Is the Boiler Upgrade Scheme?

Key eligibility criteria for the Boiler Upgrade Scheme include:

  • You are a homeowner, small landlord, or private landlord in England or Wales.
  • You possess a valid Energy Performance Certificate (EPC) with no outstanding loft or cavity wall insulation recommendations.
  • The replacement is for an existing fossil fuel heating system (e.g., oil, gas, direct electric) and not a low-carbon heating system.
  • The installation capacity of the new heating system is up to 45kWth (kilowatt thermal capacity), which is suitable for the majority of UK properties.

Homeowners with outstanding recommendations for loft or cavity wall insulation may still apply for the scheme if the installation of these types of insulation was completed during the voucher validity period, as confirmed by a newly generated EPC at the voucher redemption stage. 

This makes air to air heat pumps more accessible and affordable for homeowners, aligning with the UK’s efforts to promote energy-efficient and eco-friendly heating solutions. Additionally, until 2027, homeowners can benefit from paying 0% VAT on their air to air heat pump installation. This provides an added financial incentive to act promptly.

What Are the Efficiency Rates of Air to Air Heat Pumps?


The efficiency rates of air to air heat pumps are generally measured using a metric called the Coefficient of Performance (COP). The COP of an air source heat pump tends to be fairly stable within a specific temperature range. Here’s how it typically works:

  1. COP Range: The COP of air source heat pumps typically falls within a range of 2 to 3 when the outside temperature is between -3°C to 10°C. This means that for every unit of electricity consumed by the heat pump, it can generate 2 to 3 units of heat energy.
  2. Moderate Temperatures: During days when the outdoor temperature falls within the range of -3°C to 10°C, the heat pump operates efficiently, and its COP remains relatively constant. This makes it a cost-effective and energy-efficient option for heating your home during most of the heating season.
  3. Colder Days: On colder days when the outside temperature drops significantly, the COP may decrease. This is because the heat pump needs to work harder to extract heat from the colder air. As a result, it may become less efficient in transferring the same amount of heat.
Outdoor Temperature Range COP (Coefficient of Performance)
-3°C to 10°C Typically stable between 2 – 3
Below -3°C Lower, such as 1

The efficiency of air to air heat pumps can vary based on the specific make and model, as well as the design and insulation of your home. To maximise efficiency, it’s a good idea to choose a heat pump that matches the climate in your region and to ensure that your home is well-insulated. Additionally, regular maintenance of the heat pump system can help maintain its efficiency over time.

How do Air to Air Heat Pumps Work?


Air to air heat pumps, also known as air source heat pumps, work by using the principles of thermodynamics to extract heat from the outside air and transfer it into your home for heating or expel it outside for cooling. 

During the heating mode, the outdoor unit of the air to air heat pump contains a refrigerant that circulates through a closed-loop system. Even in cold outdoor air, this refrigerant has the ability to absorb heat energy. 

When the air source heat pump operates, a fan draws in air from the outside. This air contains heat energy, even if it’s relatively cold. The refrigerant in the outdoor unit absorbs this heat energy, causing it to evaporate and turn into a low-pressure, low-temperature gas.

The low-pressure, low-temperature gas is then compressed by a compressor in the outdoor unit. As it is compressed, the gas’s temperature increases significantly. This hot, high-pressure gas is then passed through a coil or heat exchanger in the indoor unit.

Inside your property, a separate indoor unit contains a fan or blower. The hot gas passes through the coil in this indoor unit, and as it releases its heat, it condenses back into a liquid. The heat exchanger in the indoor unit warms the air circulating within your home. This warm air is then distributed throughout your living spaces, providing heating.

Air to air heat pumps are versatile, as they can operate in reverse during the cooling mode. In this mode, the indoor and outdoor units switch roles. The indoor unit absorbs heat from your home’s interior and expels it outside, effectively cooling the indoor spaces.

The process continues in a cycle, with the refrigerant continuously circulating through the system. Whether heating or cooling, the air to air heat pump uses the same basic principles of heat exchange, but the direction of heat transfer is reversed.

Disadvantages of Air to Air Heat Pumps

Disadvantage Description
Seasonal Dependency Efficiency depends on outdoor temperature, working best between -3°C and 10°C, with increased power consumption at lower temperatures.
Dust Utilising fans for heating/cooling can disperse dust in the room.
Lower Heat Supply Provides less heat compared to oil or gas boilers, potentially requiring larger vents.
Additional Expenses In colder regions, additional elements may be needed for optimal results, but these are relatively low in cost and pay off in the long run.
