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.
