Air Source Heat Pumps - How do they work?
In brief, an Air Source Heat Pump (ASHP) uses the heat energy from the air and draws it in to convert it to energy that can heat your home.
Also known as "air-to-water" pumps, the heat captured is used to warm the water that passes round your heating system (normally radiators).
Depending on your property and pre-existing heating type, you can save up to £1000 per year on your fuel bills that's over £19 per week!
Heat pumps have a better efficiency than other heating systems because the amount of heat produced by them outweighs the amount of electricity they use. The heat produced for every unit of electricity used is referred to as the Coefficient of Performance (CoP). So, a heat pump with a CoP of 3.0 will give out three heat units for every electricity unit consumed.
A standard air-to-water heat pump requires hot water to be stored for when you need it. The size of the hot water cylinder needed is dependent on the volume of hot water that you require, but it usually fits inside a cupboard measuring 800x800mm. This allows the ASHP to gradually heat the water, with the cylinder storing the hot water for when you need it.
If you're short on space for a hot water cylinder, there are other options. Some hybrid systems are designed so that the heat pump provides space heating, while the boiler provides hot water instead.

From EST ASHP In Depth Guide:
Everything around us contains thermal energy – or heat. Heat naturally flows from a warmer place to a colder place. To provide the heat energy in a home when outdoor temperatures are colder, we need heat to flow in the other direction – from a colder place to a warmer place. But how does it do it?
When the pressure of a gas increases, the temperature also increases. When the pressure decreases, the temperature decreases. This relationship between pressure and temperature is the key to how a heat pump works.
The gas is called a ‘refrigerant’ and a heat pump uses electricity to compress this refrigerant, increasing the pressure and therefore the temperature.
As the refrigerant’s heat is transferred to your home through the heat exchanger, it cools down a little. The refrigerant is then allowed to expand so that it cools even further. It’s now cold enough to absorb more heat from outside and begin the process again.
The heat delivered to the heat exchanger can then be used to heat your home. This would normally be done using a central heating system – but it could also be done using warm air in either an air-to-air heat pump or an exhaust air heat pump.
With an air source heat pump (ASHP), the cold refrigerant starts its journey in the outside unit (called an evaporator). It absorbs heat energy from air blown across a heat exchanger, using fans. Although the air is cool in the winter, there is plenty of energy available because of the large volume of air that passes over the heat exchanger.

The Benefits of an Air Source Heat Pump
Super Efficient
Up to 300% efficiency means an air source heat pump will greatly outperform almost every other heating system.
Low Operation Temp
The ability to operate in temperatures down to -20C means that even the coldest of Scottish mornings won't phase them!
Renewable Energy
As a producer of your own energy, you'll be less dependent on the National Grid and fossil fuels.
