How Do Heat Pumps Work?

If you are looking for ways to make your heating system more efficient and eco-friendly, you may have come across heat pumps…

This technology has helped people all over the country get closer to net zero. But what are heat pumps? And how do they work? In this blog post, we will discuss some of the important information you might need to know about heat pumps should you consider buying one for your home.

What Does a Heat Pump Do?

In short, heat pumps use electricity to extract heat from the outside air and transfer it into your home, where it is used to warm water for your central heating system, radiators, or underfloor heating – which is especially useful during the colder months.

They offer a more energy-efficient and eco-friendly way to heat your home compared to traditional gas boilers or electric heaters.

These systems also provide reliable year-round performance, making them a practical and sustainable alternative for modern home heating.

How Does a Heat Pump Work?

Heat pumps use the same technology as air conditioners but in reverse. While an air conditioner pulls cool air from outside and brings it inside, a heat pump does the same for hot air.

Both heat pumps and air conditioners contain a component called a refrigerant, which allows them to do this. The only difference between the two is that a heat pump has a reversing valve, allowing it to heat your home.

How Do They Work – Step-By-Step

•  - The process begins by absorbing heat from either the ground or the outside air.
•  - Absorbed heat causes the refrigerant liquid to evaporate into a gas.
•  - The gas is compressed, raising its temperature.
•  - Heated gas passes through an internal heat exchanger, transferring heat to the home's interior.
•  - Heat can be circulated directly or used to warm water.
•  - As heat is transferred, the gas cools and condenses back into a liquid; the cycle repeats.

Do Heat Pumps Work in Cold Weather?

Yes! Heat pumps do work in cold weather - in fact, they have to by design. One of the more common questions asked about heat pumps is how they pull in hot air if it's cold outside, and the answer is fairly simple.

Even on cold days, there is still a small amount of heat in the air. Heat pumps are just very effective at pulling in the smallest amount of heat to make sure your home is warm. This does, however, require you to have efficient insulation to keep all the heat inside.

What Types of Heat Pumps Are There?

There are two main types of heat pumps, air source and ground source heat pumps. But how are they different? Read more below.

Air Source Heat Pumps

Air source heat pumps are the typical type of heat pump that most people think about. These units will take heat from the air outside and use it to heat your home. At Liverpool Heating, we specialise in air-to-water heat pump installations. Contact us today for a quote.

Ground Source Heat Pumps

Alternatively, ground source heat pumps use the heat from the ground pumping liquid through pipes. Then the pump will increase the temperature to provide heating and hot water to your home.

These heat pumps work similarly to boilers which also use heat from the ground to distribute hot water and heating. The main difference being that heat pumps are much more environmentally friendly and will produce no carbon emissions.

How Much Do Heat Pumps Cost?

The cost of a heat pump will depend largely on the type you choose. Air source heat pumps generally cost around £12,400 to £25,000, while ground source heat pumps are roughly £10,500 - £37,000.

If you would like to learn more about the costs of air source heat pumps specifically, you can read our guide where we talk in more detail about the different factors that will affect the costs of air source heat pumps.
