Air source heat pumps explained


An air source heat pump (ASHP) is usually placed outside at the side or back of a property, and takes heat from the air and boosts it to a higher temperature using a heat pump. This heat is then used to heat radiators, underfloor heating systems or even warm air convectors and hot water in your home.


Air source heat pump costs and savings


ASHPs are cheaper than ground source heat pumps. The Energy Saving Trust (EST) estimates that the cost of installing a typical ASHP system ranges between £7,000 and £14,000.

The payback period (the time it takes for the cost of the system to be recouped in energy savings) depends on how efficiently your system works, the type of system you're replacing, whether you can get money with the RHI and how you'll be using the heat generated from the pump.

The EST says that an average performing air source heat pump in an average four-bedroom detached home could save:


•  Between £545 to £880 a year if replacing oil

•  Between £550 and £1,060 a year if replacing electric heating.

It also estimated that he RHI would pay an extra £805 to £1,280 a year.


Here are some general rules of thumb to bear in mind:

•  Like ground source heat pumps, air-to-water ASHPs work better with underfloor heating systems. If underfloor heating is not possible, you should consider using our DIMPLEX SMART RADS. This is because the heat generated by the heat pump is not as high as that produced by a conventional boiler, so a larger surface area or fan convector radiator is needed to achieve similar temperatures in your home.

•  Air-to-water heat pumps could be extra efficient when installed to properties that have had or are considering having SOLAR PV installed as the ASHP requires electricity.

•  Heat pumps can save you more on your heating bills if you're replacing an electric, oil, LPG or coal system, rather than gas.

•  A well-Insulated house is essential to best optimise the heat generated by your ASHP - otherwise the heat the pump is generating escapes more easily.

•  Once in place, the heat pump should require little maintenance.

•  Heat pumps qualify for the Renewable Heat Incentive (RHI).


Pros of air source heat pumps

•  Air source heat pumps can generate less CO2 than conventional heating systems.

•  ASHPs can provide heating and hot water.

•  They require very little maintenance.

•  They can be used for air conditioning in the summer.

•  You need to use electricity to power the pump which circulates the liquid in the outside loop, but for every unit of electricity used by the pump, you get between two and three units of heat – making this an efficient way to heat a building.

•  Cheaper Economy 7 electricity tariffs can be used to lower the cost of electricity to power the heat pump and special heat pump tariffs may be available from some electricity suppliers – alternatively consider solar panels (hyper link to pv page) for a greener source of electricity.
