What is a heat pump

A heat pump is an energy-efficient device that can save energy in the home by using a small amount of electrical energy to move heat from one place to another. Unlike a boiler, which creates heat by burning fuel, an air source heat pump simply transfers heat from the air outside the home to the inside of the home.

During the winter, a heat pump extracts heat from the outdoor air or ground and transfers it to the inside of the home, warming it up. During the summer, it can work in reverse, removing heat from inside the home and transferring it outside, cooling the home down.

The efficiency of a heat pump is measured by its coefficient of performance (COP), which is the ratio of the heat output to the electrical energy input. Heat pumps have a higher COP than traditional heating systems, meaning they require less energy to generate the same amount of heat.

By using a heat pump to heat and cool your home, you can save energy and money on your energy bills. Additionally, many heat pumps use environmentally friendly refrigerants and produce fewer emissions than traditional heating systems, making them a more sustainable choice for your home.

The UK heating market faces several challenges, including:

Energy efficiency

The heating market is under pressure to become more energy-efficient due to the UK's commitment to reducing carbon emissions. There is a need for more efficient heating systems and renewable energy sources such as heat pumps.

Aging infrastructure

Much of the UK's heating infrastructure is old and outdated. This makes it difficult to upgrade to more efficient systems, and can also lead to reliability issues.

Fuel poverty

Many households in the UK struggle to pay their heating bills, leading to fuel poverty. This is a significant problem, particularly for vulnerable households such as the elderly and those on low incomes.

Lack of innovation

There is a perception that the UK heating market has been slow to innovate, with a lack of investment in new technologies and approaches.


The heating market is subject to a complex web of regulations, which can make it difficult for new entrants to enter the market and for existing players to adapt to changing market conditions.

Skills shortage

There is a shortage of skilled workers in the heating industry, particularly in areas such as installation and maintenance. This can make it difficult to deliver high-quality services and to implement new technologies.

Did you know that a heat pump can cool the house in summer?

Most heat pumps have both a heating and a cooling function, this is seldom used in the UK as the summers are relatively short. But as the summers are starting to warm due to climate change, we have seen an increased demand for the cooling feature to be accessed, this can be delivered in many ways in your home, either by underfloor heating system, MVRH (mechanical ventilation heat recovery) or fan assisted radiators (fan coils).

A heat pump is a device that can extract heat from one location and transfer it to another. It operates on the principle of refrigeration, using a refrigerant to absorb and release heat as it circulates through the system.

Here’s a basic overview of how a heat pump works:

The heat pump has two sets of coils, one inside and one outside. The coils are filled with a refrigerant, such as R32, which is used to transfer heat.

The outdoor coil contains a compressor that compresses the refrigerant, which concentrates the energy in that volume and causes it to the temperature to rise. This hot gas then flows into the indoor heat exchanger, where heat is extracted for heating and hot water.

The now-warm refrigerant then flows back outside, where it is compressed and the cycle starts over again.

So, in heating mode, the heat pump extracts heat from the outside air (even when it’s cold outside) and transfers it inside to warm the space. In cooling mode, the process is reversed, and the heat pump extracts heat from the indoor air and transfers it outside to cool the space.

Overall, a heat pump is an efficient way to heat and cool your home, because it moves heat from one location to another, rather than creating heat (like a furnace) or removing heat (like an air conditioner).
