How do Air Source Heat Pumps work?
They take energy from the air using an Air Handling Unit. This box is situated outside and contains a large fan that draws air into the unit, transferring the energy in the air through large heat exchangers. From there, the process is the same as a Ground Source Heat Pump. They work like a fridge by moving energy from one place to another. For example, a bottle of wine brought from your local supermarket is at room temperature. If you put it in your fridge and wait a few hours it will be cold enough to drink. If you touch the back of your fridge during that time you will feel heat. The fridge has taken the low temperature energy out of the wine, compressed it up to a higher temperature and in effect has warmed the kitchen up slightly. By using the same process Heat Pumps remove solar energy stored in either the earth, air of water around your building, compress it to a higher temperature and transfer it into your central heating system and hot water tank.
