WHAT IS A HEAT PUMP?
Heat pumps are an energy-efficient alternative to furnaces and air conditioners for all climates. A box not much bigger than a large armchair, effectively sits on the side of your property and magically transforms cold outside air to hot water that fills your radiators and underfloor heating systems.
​
Like your refrigerator, heat pumps use electricity to transfer heat from a cool space to a warm space, making the cool space cooler and the warm space warmer. A heat pump extracts heat energy from the air or ground, even when it is cold outside, and uses it to warm your home. A well-designed heat pump system transfers around three to four times more energy into a property as heat then it uses to extract it.
Air source heat pumps can be installed in a matter of just a couple of days and can go on to last up to 20 years. They require minimum maintenance, require cleaning every couple of months ,and an annual service.
​
An air source heat pump can match the entire repertoire of a traditional gas boiler but does so with minimal electricity and little damage to the environment.
​
Possibly the most mind-blowing factor about the air source heat pump is that the government will pay you back in instalments every month for up to 7 years as a part of an incentives scheme to get the UK on to renewables.
HOW DOES A HEAT PUMP WORK?
There are two key types of heat pumps – either ‘Air-to-Air’ or ‘Air-to-Water’.
​
Air to Air heat pumps operate under the same principle the air conditioners do, the only difference, and a decisive one is that the former function the other way around in comparison to the latter. The air source heat pumps extract the heat from the outside masses of air and transfer it to the pump’s indoor unit compressor. This process is entirely based on the principle of heat transfer, which is supported by the pump’s refrigerant property to lower the temperature of the air that is passed through the device. Thus, the thermal value of the incoming air is the ambient temperature level, which leads to the thermal isolation of the air heat. This refrigerant takes on heat energy from the outside ambient air temperature and turns into a gas as it warms up. This gas is then compressed back into a liquid, which increases its temperature further. The warm refrigerant then goes through a heat exchanger, which transfers the warmth to a separate body of water for circulating round the central heating system. During the final stage the liquid refrigerant goes through an expansion valve reducing the pressure and temperature and the cycle repeats.
Air-to-Water heat pumps transfer heat from the outside air to water, which heats your radiators or underfloor heating. It can also heat water stored in a hot water cylinder for your hot taps, showers, and baths. Heat from the air is absorbed into a fluid. This fluid then passes through a heat exchanger into the heat pump, which raises the temperature and then transfers that heat to water. The criteria by which heat is transferred can be simplified as follows:
​
-
An outdoor unit takes in heat from the ambient air and transfer it to a coolant
-
A compressor increases the temperature of the coolant
-
The coolant transfers the heat to a hot water reserve tank via a heat exchanger
-
Hot water is circulated to radiators and faucets
-
Cold water is transported back to the tank
-
The coolant is transferred from the tank to the outdoor unit
