Recent advances in technology mean that modern air source heat pumps are self-contained units and only ever require electric and/or water connections. They are low maintenance, quiet to run and can be discreetly placed inside or outside homes. They are also suitable for small retail outlets and commercial buildings.
In simple terms an air source heat pump is a system that transfers heat from outside to inside a building. They use vapor compression refrigeration, where a refrigerant system involving a compressor and a condenser absorb heat at one place and release it at another.
There are two main types of ASHP: air-to-water and air-to-air. First Choice Aircon specilise in air to air units and you can find additional information about then on our warm air heating pages .
To tell if an air source heat pump is right for you, there are a few key questions to consider:
- 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.
- What type of heating system will you use? Air source heat pumps perform particularly well with underfloor heating systems or warm air heating because they operate at low temperatures.
- Is your home or business well insulated? Since air source heat pumps work best when producing heat at a lower temperature than traditional boilers, it’s important that your home is well insulated and draught-proofed to minimise heat-loss.
- What fuel will you be replacing? The system is more likely to pay for itself if it’s replacing an expensive system like electric heating. You’re unlikely to save much on your heating bill if you’re switching from mains gas.
Additional information on both types of ASHP systems can be found on the energy saving trust website.
Air to Air Heat Pumps
Many people are unaware but most of the major air conditioning manufacturers are also producing devices capable of operating in a heating mode. These air to air heat pumps enjoy special interest here at First Choice Air Conditioning, mainly due to the ease of operation, and relatively low operational and installation costs.
How Do Air to Air Heat Pumps Work?
Air to air heat pumps operate under the same principle air conditioners do, the only difference is that one heats and the other cools. The air source heat pumps extract the heat from the outside masses of air and transfer it to the pump’s indoor unit compressor. This process is entirely based on the principle of heat transfer, which is supported by the pump’s refrigerant property to lower the temperature of the air that is passed through the device. Thus, the thermal value of the incoming air is below the ambient temperature level, which leads to the thermal isolation of the air heat.
Air to Air Heat Pump Benefits
- Capable of providing heating during the cold season and air cooling during the hot days of the summer.
- Low installation costs. There is no need to drill boreholes, install complex heat distribution systems, like radiators or underfloor heating or use expensive installation equipment.
- The ability to transfer a significant amount of heat.
- Easy to use as contain climate control thermostats that automatically monitor the pump’s functioning parameters.
- They are highly efficient. The seasonal efficiency rating (SCOP) can reach 3.0-4.0, meaning that for every 1 kW of electricity 3 to 4 kW of heat is generated.
- Low Background noise
- Environmentally friendly. The air source heat pumps do not release any harmful gases or components into the atmosphere.
