How it works
Air conditioning uses a heat pump to move unwanted heat energy from the space to be cooled. The heat energy is discharged outside.
​
Modern air conditioning heat pumps can also be used in reverse to provide energy efficient heating in the same space, during cold periods.
​
Even on a cold winter day there is a lot of surplus heat energy in the air. It is very cost effective to use electricity to move this energy from the outside into the space to be warmed.
​
Heating a space directly with electricity (know as resistance heating) produces one unit of heat energy for every one unit of electricity used.
​
​
In summer
Heat energy inside the house is collected and removed by discharging it into the outside air.
​
​
​
In winter
Heat energy from the outside air is collected and moved inside the house.
Using a heat pump to move existing heat from the outside is much more efficient. Typically, one unit of electricity can move more than 3 units of heat energy from the outside to the inside. Hence, heating a space with a heat pump is more than 3 times as efficient as using electrical heating. This makes it competitive with other efficient methods such as gas central heating. But of course, gas central heating cannot cool your house in the summer!
Another way of looking at it
-
If you need air conditioning during warm times, you also get energy efficient heating for the cooler times.
