Climate change and the need to reduce our impact on the worsening environment has seen the human race turn more and more to renewable methods of heating and lighting our homes. The solutions become ever more innovative and now include extracting heat from the sun, the ground and now even the air.
A brief introduction
An air source heat pump sounds like something that could only be used in hot countries, but in fact warmth from the air can be used to heat your home even if the outside temperature is below 10 degrees Celsius. The system works by extracting heat from the outside in the same way that a refrigerator extracts heat from inside. The heat gathered is transferred to where it is needed, either to heat your home via air convection or underfloor systems, or to heat water in the hot water tank.
Although the heat provided by an air source heat pump is from a renewable source (the air), just as with a refrigerator, the extraction and transferral process requires electricity to work. However, the system requires far less energy and produces much lower carbon emissions than a conventional heating system, so one of the advantages of using heat from the air is lower heating costs.
You may also be eligible for payments from the Renewable Heating Incentive (RHI) scheme run by the UK government, which rewards homes that employ renewable sources of heat and power. Other benefits include safety and versatility. Once you have installed the system, it does not require much maintenance.
Typical installation costs for an air source heat pump range between £7,000 to £11,000. The exact cost will depend on various factors such as the size and layout of your home, your current heating system, the insulation level in your building and the temperature you want to achieve in your rooms.
There are various set-ups whereby the heat extracted from the air is put to different uses, either to heat air or to heat water. When it comes to running costs for an air-to-air heat pump, costs per kW of peak heat output vary from up to £1,150 for a smaller system (5-10kw) to below £600 for a larger system (10-20kw). For an air-to-water heat pump, costs per Kw of peak heat output range from up to £1,200 for a smaller system (5-10kw) to as low as £550 for a larger system (10-20kw).
Considerations for installing an Air Source Heat Pump
Before installing an air source heat pump, you should consider whether you have space to place the system. Although the pump itself does not take much room, it is important to have enough free air space around to get a good flow of air. An air source system is most effective with an underfloor or warm air heating system because the temperatures required for these systems are lower than those needed for traditional radiator systems. As mentioned above, it is imperative that your home is well insulated to prevent loss of heat and draughts.
