What is a Heat Pump?

Many People describe heat pumps as being “fridges in reverse !”, which to all intense purposes is exactly what they are, they even look like fridges. The only difference is that heat pumps take the heat from the environment and pump it into the house instead of a fridge, which takes the heat out of the fridge and dissipates it into its surroundings.

The basic principle is quite simple and the beauty of a Heat Pump, is that provided it is one of the more efficient models, it requires very little energy to run, which means that customers will save massively on their heating and hot water costs. Indeed, if a heat pump system is combined with other forms of renewable energy, and provided that the property is properly insulated, the cost of heating and providing hot water for the home can be minimal if Feed in tariffs and Renewable Heat Incentives (RHI’s) are included in the equation. The only real issue is that the initial outlay for any kind of low energy home with renewable sources is higher than that of a more conventional heating system, gas for example. The long term reward however, far outweighs the initial costing and the overall return makes for the most prudent household investment available in today’s increasingly expensive energy market.

So how do heat pumps Work ?

All particles of matter contain energy down to a temperature of -273 degrees Celsius (known as absolute zero), where the vibrational levels of the subatomic particles literally freeze or stop.

Heat is basically energy that is being dissipated from a source of energy.

So to heat our homes we need to take the energy from a source and by certain means (eg: combustion, or changing a gas into a liquid and visa versa) dissipate that energy around the property in the form of HEAT.

A Heat Pump will use a refrigerant liquid to circulate in the outside environment, pick up energy from the outside environment and dump that energy into our homes before being pumped back outside to gather more energy. It can do this by the intervention of a small compressor which changes the state of the refrigerant from gas to liquid and back again in a continual cycle. And it does this at an incredibly high rate of efficiency. In the ideal case the heat pumps can work with a coefficient of performance of between 3 and 4. This means that for every unit of energy put into the Heat Pump, You could potentially get three to four times that amount out. This depends on a number of factors, such as outside temperatures, humidity, wind speeds, and time of year.

The cost of running Heat Pumps can be made even more attractive when combined with a Solar PV System which will actually supply some of  the electricity needed to run the heat pump!
