Air Source Heat Pump Grants England

Although Air Source Heat Pump Grants England may be available from the Affordable Warmth Scheme from 1st January 2020, the main financial incentive for installing air source heat pumps is the Domestic Renewable Heat Incentive.

The Domestic Renewable Heat Incentive pays tariffs every three months for seven years if you install an air source heat pump and comply with the regulations.

The current RHI tariff for air source heat pumps is 10.71 pence per kilowatt hour (kWh) and is based on the Heat Demand figure from your Energy Performance Certificate (EPC). You can view your EPC HERE.

How are Air Source Heat Pump RHI Tariffs Calculated?

The Heat Demand figure from your EPC is multiplied by the current RHI tariff, expressed in pence. If your Heat Demand is 15,000 kWh, your gross RHI tariff would be £1,606.50, although this is adjusted for the Seasonal Performance Factor (SPF) for your particular air source heat pump.

(Please see ASHP FAQs for more information about how the SPF affects your RHI tariff receipts).

However, the maximum annual heat demand limit for air source heat pumps is set at 20,000 kWh so the maximum gross annual RHI tariff you can claim is £2,142.

How do Air Source Heat Pumps Work?

Air Source Heat Pumps extract heat from the outside air and use it to heat your home. This heat is transferred inside to keep your central heating radiators warm and to provide hot water for your taps and showers. Air Source Heat Pumps will even work when the temperature outside is below zero.

There are several components inside an air source heat pump which enable them to extract heat from air and use it to heat your home.

  • Fan – An electrically operated fan sucks air from outside, into the air source heat pump.
  • Evaporator – This transfers heat from the air to a refrigerant liquid in a sealed network of pipes similar to a refrigerator. The heat causes the refrigerant liquid to evaporate, which turns it into a gas.
  • Compressor – The gas is then compressed, causing its temperature to increase substantially.
  • Condenser – The heated gas is now transferred to a condenser where it is cooled, causing it to turn back into a liquid. The act of cooling hot gas releases heat which is used to heat water, some of which is within the network of pipes and radiators and, separately, some of which is available at your taps.
  • Expansion Valve – Now that the hot gas has been converted back to a cool refrigerant liquid, an expansion valve releases it and the whole process starts again. In essence the process is continuous and never stops.

Air source heat pumps use far less electrical energy that the heat energy they create. This makes them more than 100% efficient. Typically, for every unit of electrical energy used by an air source heat pump, it generates over 3 units of heat energy. This means that air source heat pumps are more than 300% efficient, compared an A rated gas boiler which is around 95% efficient.

By using less energy to heat your home and provide hot water you are able to cut both your heating bills and your carbon emissions.

Benefits of Air Source Heat Pumps

Air source heat pumps require very little maintenance. An annual check of the main components, cleaning the filters and a safety check is all that is needed.

Air source heat pumps are easily controllable and they maintain a stable temperature inside your home.

No more deliveries of oil, LPG or coal are required.

Air source heat pumps will reduce your home heating bills.

The component parts of air source heat pumps last a long time and long warranties are available.

Switching to an air source heat pump will reduce carbon emissions from your home.

Domestic Renewable Heat Incentive incentives are available for 7 years after installation.

Air Source Heat Pumps FAQs

How much space is required for an air source heat pump?

The NIBE™ F2040 air source heat pump is 895 mm high, 1,035 mm wide, 422 mm deep and weighs 90kg.

You will need a space outside where the air source heat pump can be installed, usually against an outside wall and space around it to allow air flow.

Will I cut my heating bills with an air source heat pump?

Yes.

Most air source heat pumps are more than 300% efficient at converting electrical energy into heat energy. This means that you will need no more than one third of the energy you currently use to heat your home and provide hot water.

Using less energy means that you cut your heating bills and your carbon emissions.

Can I get a grant to help install an air source heat pump?

Grants may be available from the Affordable Warmth Scheme from 1st January 2020 but you should consider the Domestic Renewable Heat Incentive (DRHI) as well.

It is doubtful that you will be able to apply for both schemes.

Instead of an upfront grant to help with the installation cost of an air source heat pump, the DRHI pays a quarterly tariff for seven years based on the annual heat demand for your home. This can be found on your Energy Performance Certificate (EPC).

Householders in Scotland can see their EPC HERE.

How much will I receive in DRHI tariff payments to install an air source heat pump?

The DRHI tariff is calculated based on the annual heat demand for your home which can be found on your Energy Performance Certificate. Householders in Scotland can see their EPC HERE.

The current DRHI tariff for air source heat pumps is 10.71 pence per kilowatt hour. Therefore, if the annual heat demand for your home is 18,000 kWh, your gross annual DRHI tariff will be £1,927.80 (18,000 x 10.71p).

However, because your air source heat pump uses electricity and the Renewable Heat Incentive Scheme will not pay a tariff for the electricity it uses, the gross tariff amount is reduced by the Seasonal Performance Factor (SPF) for your particular air source heat pump.

The adjusted annual RHI tariff payable is calculated as follows:

Domestic Renewable Heat Incentive ASHP tariff calculation adjusted for SPF

In the example above, if the SPF for your air source heat pump was 3.0 (i.e. 300% efficient) the gross annual DRHI tariff of £1,927.80 would be reduced to an actual payment of £1,291.63 per year.

18,000 x 0.67 x 0.1071 = 1,291.62 or £322.91 per quarter.

You can an estimate of your DRHI tariff amount by using the Government’s RHI calculator HERE.

How important is the insulation in my home to the effectiveness of an air source heat pump?

Air source heat pumps provide heat at a lower temperature than a traditional central heating boiler, although they do deliver it all of the time.

Consequently, your home will need to be very well insulated. Indeed, part of the application process for the Domestic Renewable Heat Incentive Scheme involves an assessment to ensure that insulation in your home is adequate.
