What is an Air Source Heat Pump?

Air Source Heat Pumps are a small unit (much like a modern air-conditioning unit in size and shape), usually placed outside at the side or rear of a property. Air source heat pumps absorb heat from the air outside, like a fridge working in reverse. This heat can then be used to heat underfloor heating systems, radiators or warm air connectors and hot water in your home The heat pump runs on electricity, but the idea is that it uses less electrical energy than the heat it produces. This can make it much more economical to run than standard electric heating.

What are the benefits of air source heat pumps?

  • The Energy Saving Trust say that a ‘typical’ air source heat pump could save you up to £380 a year (replacing electric heating)
  • Air Source Heat Pumps can provide both heating and hot water.
  • Air Source Heat Pumps require minimum maintenance.
  • Whilst you need to use electricity to power the Air Source Heat pump, you get between two and three units of heat for every unit of electricity used, – a very efficient way to heat a building.
  • Is an air source heat pump suitable for my property?

  • As Air source Heat pumps work better with under floor heating systems, they could be better suited to new Build Properties.
  • Is your home well insulated? A well-insulated house is essential to gain benefits from Air Source Heat Pump technology – otherwise the heat the pump is generating escapes more easily.
  • Which fuel source would you be replacing? An Air Source Heat Pump will pay for itself much quicker, if it’s replacing an electricity, LPG or Oil heating system. Air Source Heat pumps may not be the best option for homes using mains gas.
  • How much money will I save on my heating bills with an Air Source Heat Pump?

    How much money you’ll save on your heating bills with an Air Source Heat Pump will depend on what system you use now, as well as what you are replacing it with.

    Your savings will be affected by:

  • Your heat distribution method;
  • Because the water doesn’t need to be as hot, underfloor heating can be more efficient than radiators. If underfloor heating isn’t possible, use the largest radiators you can. Eco-Exmoor Ltd can advise you on this.

  • Your energy running costs;
  • You will still have to pay energy bills with an Air Source heat pump, as it is powered by electricity. However if the fuel you are replacing is expensive you are more likely to make a saving.

  • Your old heating system;
  • If your old heating system not efficient, you are more likely to see lower running costs with a new Air Source heat pump. The outside Temperature Air Source Heat Pumps are generally more efficient at temperatures above 5 degrees Celsius. This makes them particularly suited to the milder winters of Somerset and the South West.

  • How you use it;
  • Learn how to control the system so you can get the maximum benefit. You will probably need to set the heating to come on for longer but set the thermostat lower. Eco-Exmoor will explain to you how to control the system to gain maximum benefit and efficiency.
