What are Air Source Heat Pumps?

Air Source Heat Pumps are a renewable alternative to heat your home and hot water.   Powered by 75% air and 25% electricity (based on the Daikin Altherma low temperature air-to-water heat pump), an Air Source Heat Pump may help you to save money on your energy bills. 

An Air Source Heat Pump can work with new or existing radiators or underfloor heating systems.  A modern, low carbon footprint approach to replace an existing boiler, or as part of a renovation, or new build.

Not only could an Air Source Heat Pump help you avoid the rising cost of energy, you can also earn money to help pay the cost of installing one.  The Government have a ‘Renewable Heat Incentive’ in place, which pays you a regular cash amount every quarter for 7 years.  The amount varies and is based on the heat demand of your property.  This is typically around £1,000+ per year, but we can advise on this as part of a detailed assessment and quotation. 

How does an Air Source Heat Pump Work?

Heat from the air is absorbed at low temperature into a fluid. This fluid then passes through a compressor where its temperature is increased, and transfers its higher temperature heat to the heating and hot water circuits of the house. 

Different from a ground source heat pump, an Air Source Heat Pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside, and it can get heat from the air even when the temperature is as low as -15° C!

Air Source Heat pumps can be much cheaper than most other fuels, and have less impact on the environment, as the heat that they extract from the air is constantly being renewed naturally.  Of course, it does need electricity to run, but is more environmentally friendly than conventional heating systems.

Would an Air Source Heat Pump be suitable for your property?

  • 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 preferable 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 may pay for itself much more quickly if it’s replacing an oil, LPG or coal heating system.

  • Is the system intended for a new development?

Combining the installation with other building work can reduce the cost of installing the system, and you can benefit from the Renewal Heating Incentive (RHI).

The Renewable Heat Incentive (RHI)

The amount that you will be paid varies depending on your property and heating demands.  Contact us for more information, or to book a free quotation and full assessment of your heating needs.
