Have you been thinking about a low carbon renewable technology to help heat your home? There are several alternative solutions to heating your home but before you decide to make the switch away from oil, LPG, electric or mains gas there are a number of considerations you should be aware to make an informed decision.

Air Source Heat Pumps are an alternative to other more traditional heating systems and there are a range of different types of Air Source Heat Pumps and different manufacturers each will have different.

Pros of installing an Air Source Heat Pump


Cheaper to run than Oil or LPG fired boiler

When installed and sized correctly an Air Source Heat Pumps are a lower cost form of heating compared to an Oil or LPG boiler.  An Air Source Heat Pump should have a seasonal coefficient of performance (SCOP) of around 3 which means that for each 1kW of electricity used to run the air source heat pump it will generate 3kW worth of heat out of it.

Low maintenance and easy to run

Air Source Heat Pump technology has been around for decades and is a tried and tested and has been proved through rigorous testing and via installs in people’s homes to be a very reliable system, requiring simply your annual service, like you would with your existing boiler.  Air Source Heat Pumps use the same technology as our fridges and freezers and these require little or no maintenance.

A low carbon heating solution

Due to the innovative technology used in the design of a heat pump them having a high efficiency, the electricity used is to produce the heat produces less Co2 emissions than alternative heating systems that use oil, LPG or gas as their main fuel source.

Heat pumps save space

A key benefit of installing an air source heat pump means you can reduce and potentially remove the requirement for fuel storage requirements.

Ideal to use with underfloor heating

Underfloor heating works best running at lower temperatures than radiators, Air Source Heat Pumps produce hot water at approx. 45c which is the ideal temperature for underfloor heating.

What considerations do you need to be aware of when installing an of Air Source Heat Pump


Air Source Heat Pumps are not suitable for all properties

An ideal property would be well insulated and draught free for an air source heat pump since an air source heat pump only produces water temperatures circa 50c whereas a traditional heating system raises water temperature to 75 – 80c.

Radiators may need to be changed

As Air Source Heat Pumps only produce water temperatures circa. 45c-50c the radiators for the house may need to be upgraded – the surveyor will be able to accurately measure the heat demand for each room and if a replacement radiator is required.

Not very attractive to look at

In the UK we’re not used to seeing Air Source Heat Pumps outside our homes – they look very similar to an air conditioning unit. It is important when looking to install a heat pump to consider where it will be situated at your house. Often they are situated on the side or at the back of the property out of sight.

Higher cost than a replacing a boiler

Whilst the running cost of an Air Source Heat Pump is lower than Oil or LPG the capital cost of the equipment is much higher and the installation more complex making it cheaper in the short term to replace an existing boiler with a newer more efficient boiler.  However, in the longer you will have a higher running cost. If you use the funded route with Orme Energy they will cover up to 99% of the cost to install the air source heat pump which means you do not need to find the money up front.
