A heat pump is a system that can heat your home in the winter and cool it in the summer by moving heat from one place to another. Instead of burning fuel to create heat, it transfers warmth from the air, ground or water outside into your home. This makes it energy-efficient and often more eco-friendly than traditional heating methods, such as boilers.
Below are the different types of heat pumps:
An air source heat pump takes heat from the outside air, even when it feels cold outside, and transfers it into your home. In the summer, some models can work in reverse, moving heat out of your home to keep you cool. They’re one of the most common types in the UK because they’re easier to install and usually cost less than other options.
What do air source heat pumps do? Air source heat pumps extract heat from the outside air and transfer it into your home to provide heating and sometimes hot water, even when it's cold outside.
A water source heat pump uses water from a nearby lake, river, pond or even a well as its heat source. Since water stays at a more stable temperature compared to air, these systems can be very efficient. However, they’re only practical if you have access to a suitable water source close to your property.
What do water source heat pumps do? Water source heat pumps extract heat from a nearby water source, like a lake or river, to heat your home and provide hot water efficiently.
A ground source heat pump collects heat from the ground outside your home using pipes buried in the soil. The ground keeps a steady temperature all year round which makes this type of pump very reliable and efficient. While they can be more expensive and disruptive to install, they often deliver excellent long-term savings.
What do ground source heat pumps do? Ground source heat pumps take heat from the ground and use it to warm your home and provide hot water efficiently.

Heat pumps are known for their high efficiency because they move heat rather than generate it by burning fuel. This means you get more heat energy out for every unit of electricity you use. They work well in mild to cold climates and some models can keep your home comfortable year-round while using less energy than many traditional heating systems.
