The Domestic Renewable Heat Incentive (“RHI”) scheme for air source and ground source heat pumps is only open for a further 7 months!
The scheme is set to end on 31st March 2022 for new applicants - that’s just 7 months away! If you are considering a ground source heat pump or air source heat pump for your home, now is the time to act in order to benefit from this generous Government grant scheme.
What Is The Renewable Heat Incentive (RHI)?
The RHI was introduced to increase the uptake of renewable heating systems, such as heat pumps and launched in April 2014. Owners who qualify for the RHI will be paid quarterly over a 7 year period for the amount of renewable heat the heat pump produces.
The tariffs shown in the table below represent the amount you receive for each unit of renewable heat generated by your heat pump to heat your home.
| Technology | RHI Tariff [p/kWh] |
|---|---|
| Ground Source Heat Pump | 21.29 |
| Air Source Heat Pump | 10.92 |
Table showing RHI Tariffs applicable from 01/04/2020 - 30/09/2021
“A typical 4-bedroom detached house will earn over over £1,200 per annum from the RHI scheme with an air source heat pump.”
Worked Example - AIR SOURCE HEAT PUMP
For a typical 4-bedroom detached house
Annual space heating and hot water requirement - 15,000kWh
Air source heat pump system capacity - 11kW
Air source heat pump seasonal performance factor - 3.99
(assuming 45C flow temperature)
This means that for each unit of electricity consumed, the heat pump produces 3.99 units of heat. The "renewable heat" is the difference between the total heat output and the electricity input. So for this example, for every 3.99 units of heat produced, 2.99 units are classed as "renewable heat", which is 75%.
Renewable Heat = 15,000kWh x 75% = 11,241kWh @ 10.92p/kWh = £1,227 per annum
TOTAL ANNUAL DOMESTIC RHI PAYMENT = £1227 PER ANNUM
For an air source heat pump in a typical 4 bedroom house, the RHI generates more than £8,500 over 7 years
Worked Example - Ground Source Heat Pump
For a typical 5-bedroom detached house
Annual space heating and hot water requirement - 20,000kWh
Ground source heat pump capacity - 14kW
Ground source heat pump seasonal performance factor - 3.33
(assuming 40C flow temperature)
This means that for each unit of electricity consumed, the heat pump produces 3.33 units of heat. The "renewable heat" is the difference between the total heat output and the electricity input. So for this example, for every 3.33 units of heat produced, 2.33 units are classed as "renewable heat", which is 70%.
Renewable Heat = 20,000kWh x 70% = 14,000kWh @ 21.29p/kWh = £2,981 per annum
TOTAL ANNUAL DOMESTIC RHI PAYMENT = £2,981 PER ANNUM
For a ground source heat pump in a typical 5 bedroom house, the RHI generates more than £20,000 over 7 years
“For ground source heat pumps in particular, any future incentives are likely to be far less generous.”
Act Now!
The current tariffs are at the highest level they've ever been, with more paid for each unit of renewable heat created by the heat pump than ever before. Coupled with the fact that scheme is ending in 7 months time, it is really time to act now.
If you have had a quote from us in the past, then please get in touch with your account manager to receive an updated quotation.
7 months may seem like a long time but due to demand in the industry there are more delays than usual which are out of our control, so act now to avoid missing out! As we get closer and closer to the RHI deadline, there is likely to be a huge demand for getting systems completed and commissioned on time.
