Low-carbon air source heat pumps

Typically save £1,597 over 10 years(1) and produce 64% less carbon emissions(2) for a gas heated home

An air source heat pump can save £1,597 over 10 years(1)

With the RHI scheme subsidising installing an air source heat pump, there's never been a better time to get one

Support with your heat pump

Daikin air source heat pumps are up to three and a half times more efficient than an equivalent gas boiler(3), so you can heat your home and water for a similar cost to gas

Thanks to the Renewable Heat Incentive, you could claim £7,574 in subsidies for an average 3 bed home(4) depending on your energy usage

Longer life & easier maintenance than a boiler

According to Energy Saving Trust, you can expect your heat pump to last 20 years or more(5) compared to 10 to 15 years for a gas boiler

We recommend a simple annual check by a qualified person

Better for the environment

An air source heat pump produces up to 64% less CO₂ than a gas boiler(2), so for a 3 bed home you can save the equivalent of 5 return flights from London to Madrid over a year(2)

Heat pumps heat your home and hot water even when temperatures outside are as low as -20ºC(6)

What is an air source heat pump?

An energy-efficient air source heat pump (ASHP) works like a fridge but in reverse. It absorbs heat from the outside air and circulates it through your heating system.

The pump uses electricity to run and can use one unit of electricity to generate up to three and a half times more heat(3).

For an air source heat pump to be effective, and to claim on the Renewable Heat Incentive, you will need at least 150mm loft insulation to prevent heat escaping through the walls or roof.

Air source heat pumps you can trust

For our equipment, we've partnered with Daikin, the biggest manufacturer of air source heat pumps in Europe with products sold in over 150 countries.

And for added peace of mind, we're working with a network of highly trained Daikin installers who are all accredited by the Microgeneration Certification Scheme (MCS) and TrustMark certified, the Government Endorsed Quality Scheme, so you know they're thoroughly vetted and commited to good customer service, technical competence and trading practices.

Funding your air source heat pump

If you join the RHI scheme – and stick to the rules – you’ll get paid for the amount of renewable heat your system produces. The payments will be made four times a year over seven years.

The payments you receive will also be determined by the type of renewable system you have.
You can use one of the government's Renewable Heat Incentive Calculators to find out how much money you could get through the Renewable Heat Incentive.
There is a RHI calculator for England and Wales, and one for the Renewable Heat Incentive Scotland.

What air source heat pump customers say

We love the Air Source Heat Pump, it provides a constant ambient comfortable temperature throughout the house. Now it’s always warm.

Anna Edwards, Bridgwater, Somerset

I am delighted with the efficiency and relatively quietness of the Air Source Heat Pump itself. It is an environmental and engineering marvel.

Peter Corkill, Canterbury, Kent

Is an air source heat pump right for your home?

Gas homes

If you have an old boiler and reasonably insulated home, then you can switch to an energy-efficient air source heat pump. Our trusted installers will recommend the right heat pump based on your needs and house type.

Oil or LPG homes

A hybrid heat pump could be the best option for you if your heating runs on Oil or LPG. A Hybrid upgrade simply adds a smaller heat pump to your home so you use less oil or LPG without overhauling your entire system.

Have you thought about insulation?

Any heating system is only effective if the heat it's creating doesn't escape through a poorly insulated roof or walls. Prevent heat loss and save up to £530 on your energy bills(7) by adding insulation to your home.

Get an exclusive zero carbon tariff

EDF is Britain's largest generator of zero carbon electricity(8). We've partnered with Daikin to offer an exclusive low-cost zero carbon tariff for our heat pump customers.

Once your new system is installed, Daikin or the installer will provide you with details on how to access the exclusive tariff.

Notes

Calculation is based on:
- Heat pump on offer is a package of 7KW air source heat pump with designed efficiency (SCOP) of 3.48, radiator upgrades, hot water tank and installation.
- Typical upfront price of £8,999 is for a 3 bedroom property in the South of the UK with annual heat demand of 13,903 kWh consumption for heating and hot water, at least 150mm insulation and built between 1960-1980.
- Our expert installer will provide a more accurate assessment of heat pump cost & savings based on your individual needs and house type
- Boiler cost of £3,324 from recent govt study where we assume a non-combi boiler of 24KW and boiler efficiency of 93%
- It does not differentiate between bedroom sizes so its an average across all property types: https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/913508/cost-of-installing-heating-measures-in-domestic-properties.pdf
- Heat pump lifetime is usually 15-20 years compared to boiler of 10 years
- Energy & carbon price assumptions from https://energysavingtrust.org.uk/about-us/our-calculations
- RHI subsidy of £7,574 (based on 10.92p/kWh)
Heathrow to Madrid, Spain is 1243 km one way.
BEIS - UK Government GHG Conversion Factors for Company Reporting 2020 - Air Travel with RF factor included states 0.378394 tonnes of CO₂ per economy passenger for a return flight.
The carbon difference between a heat pump and boiler is calculated as:
A - 13,903 kWh of energy demand for heating and hot water
B - 3.48 heat pump designed efficiency
C - new boiler efficiency of 93%
D - Gas fuel emissions of 208 gCO₂/kWh
E - Electricity fuel emissions of 277 gCO₂/kWh
Gas CO₂ = (A/C*D) = 3.11 tonnes
Electricity CO₂ = (A/B*E) = 1.11 tonnes
1-(1.11)/(3.11) = 64%
Three and a half times more efficient is based on a heat pump efficiency of 3.48 vs a gas boiler of 93% or 0.93. 3.5 x 0.93 = 3.25, which is less than 3.48.
Based on a 13,903 kWh heat demand and an assumed maximum efficiency of 3.48 (SCOP) will be eligible for RHI subsidy of £7,574 (based on 10.92p/kWh)

UK Fuel Mix disclosure information, published by Government Department BEIS, recognises electricity from wind, solar and nuclear fuel produces zero carbon dioxide emissions at the point of generation.

The zero-carbon electricity purchased is supplied into the National Grid. Customers receive electricity via the National Grid, not directly from zero-carbon generators.

The below table summarises zero-carbon generation by company demonstrating EDF generating 29.4%. The data supporting the table below and the % values is sourced from a mixture of industry settlement data and the UK government renewable obligation database.
