Air Source Water Heating - How Does it Work?

05
Sep
Air Source Heat Pumps make a very efficient alternative heating system for water heating.
 
The pumps work on the principle of absorbing heat from the outside air which is then used to heat radiators, underfloor heating systems or warm air convectors and heat water in your home.
 
The pumps continue to work well and absorb heat even when the temperature is low - although they are inevitably more efficient in mild climates that have temperatures above 4.4°C. Whilst they consume additional electricity, the total usage is not high.
 
How do they work? A thermodynamic system can be located in an airing cupboard, loft or utility room. It then absorbs heat from the air which is used to heat a liquid refrigerant. Electricity is used to compress the liquid to gas. This compressed gas then condenses back to liquid to release heat. The heat is then transferred to the water through a heat exchanger taking the water as high as 62°C.
 
The system activates automatically when the stored hot water cools by 3-5°C. This essentially means that you will never run out of hot water. You also have an option to set a timer so it only operates during the daytime when air temperatures may be higher. If you have solar PV installed then electricity you produce can power the system - further reducing cost. 
 
The system can continue to work even while you are running a bath which ensures that you will have continuous hot water without a drop in the temperature.
 
You can have cylinders up to 260 litres with various size options. The noise levels are minimal as the unit is very quiet and will be no louder than a freezer when it operates in cooling mode.
