Air Source Heat Pumps

At approximately 40% more efficient than a gas condensing boiler an air source heat pump is a great for the environment and saves money on your energy bills, especially if your upgrading from oil or LPG. For every 1KW of electricity energy consumed by the air source heat pump you could get at least 3KW of heating energy out.

The thinking that this technology is un suitable for the British weather is un true,  air source heat pumps can produce water temperatures of up to 60°C when the outside ambient temperatures as low as -25°C. 

Furthermore, by installing an air source heat pump you will be eligible for the RHI Renewable Heat Incentive scheme. This is a government incentive to reduce carbon emissions and reward you to move away from fossil fuels to heat their homes. Working in a similar way to the Feed-in-Tariff for solar photovoltaic (solar PV) systems, owners of heat pumps will be paid according to the total heat load of the property in kilowatt hours, for seven years tax-free.

An Air source Heat Pump work by transferring heat absorbed from the outside air to an indoor space to heat radiators and provide hot water. These systems are far more efficient than a modern gas boiler which makes them an ideal solution for those looking reduces running costs and carbon emissions. Approved Heat Pumps may also qualify for Renewable Heat Payments (RHI) which can help fund the majority of the installation.

With the electrical grid becoming greener every year, heat pumps produce 75% less CO2 than a modern gas boiler.


The Benefits:

  • Less CO2 produced than a Gas or Oil boiler, which will only become greener as the Electrical grid decarbonises.

  • Potential income through the UK government’s Renewable Heat Incentive (RHI).

  • No fuel deliveries needed.

  • Can heat your home as well as your water.

  • Minimal maintenance required.

  • Can be easier to install than a ground source heat pump.

  • Can benefit from solar PV or battery storage systems.

Is an air source heat pump suitable for me?

To tell if an air source heat pump is right for you, there are a few key questions to consider:

  • Do you have somewhere to put it? You'll need a place outside your home where a unit can be fitted to a wall or placed on the ground. It will need plenty of space around it to get a good flow of air. A sunny wall is ideal.

  • Is your home well insulated? Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it's essential that your home is well insulated and draught-proofed for the heating system to be most efficient.

  • What fuel will you be replacing? The system will pay for itself much more quickly if it's replacing an electricity or coal heating system. Heat pumps may not be the best option for homes using mains gas.

  • What type of heating system will you use? Air source heat pumps can perform better with underfloor heating systems or warm air heating than with radiator-based systems because of the lower water temperatures required.

  • Is the system intended for a new development? Combining the installation with other building work can reduce the cost of installing the system.
