A heat pump is a sustainable, energy efficient solution to a boiler. These technologies extract heat from the air to heat your home, which is more cost-effective and efficient than gas or oil. This uses renewable technologies and is a low carbon heat source which can be installed in a wide range of homes.

Benefits of Air Source Heat Pumps
Grants for Homeowners
Many homeowners can receive support to install heat pumps from grants including Green Home Grant and RHI which helps pay for tradesmen and installing the unit.
Green Homes Grant
The government has also introduced a new grant that can be claimed from the end of September 2020 until March 2021. The Green Homes Grant offers vouchers to help reduce the upfront cost of low carbon and energy-efficient home improvements.
There are a number of home improvements for which vouchers can be used, including the installation of air-source heat pumps, ground-source heat pumps, and solar thermal.
The Green Homes Grant and the RHI scheme can be used together, with the voucher value being deducted from the RHI payments.
The Renewable Heat Incentive
The Government recognises that air source heat pumps play an important role in reducing carbon emissions from the UK’s homes. This is why air source heat pump grants have been included in the Renewable Heat Incentive (RHI).
To help offset the cost of installation, the RHI air source heat pump grant is set at a tariff rate of 7.3p/kWh. The exact ASHP grant amount over seven years depends on how much energy the household uses.
A typical home using around 20,000kWh per annum of heating requirement could receive around £7000 in payments over a seven-year period – a considerable sum to go alongside the savings on energy bills. Visit Ofgem to find out more about air source heat pump grants.
These renewable energy solutions can use as much as 70% natural energy which is absorbed from the outside air and the other 25% comes from electricity.
How does it work?
The air source heat pumps extract heat from the air absorbing this into a refrigerant fluid. This fluid is processed through a compressor which can increase the temperature of the fluid. These pumps can be effective all year round up to lows of -20c.
- Heat is extracted from the outside air and pulled through an evaporator
- A refrigerant liquid is passed through the system
- A compressor raises the temperature of the refrigerant and converts it into a gas
- The Gas refrigerant is then carried through a condenser and the heat is used to heat water.
- Once the heat is extracted the gas returned to a liquid and is reused by the system.
How do Air Source Heat Pumps reduce costs?
An air-source heat pump is possibly the most energy-efficient heat source for your home, extracting free heat from the air or ground to generate heating and hot water, and reducing your energy bills and carbon footprint.
In a well-insulated property, every kilowatt-hour (kWh) of electricity used to power the heat pump can provide around three kWh of ‘free’ thermal energy.
This means heat pumps can be up to 4x more efficient than boilers. The longer you use it, the more you can save on heating costs. Aside from their eco-credentials, an ASHP is also inexpensive to run and cost-effective in most projects, especially when you factor in the potential payback through the Renewable Heat Incentive.
