How is the size of a heat pump determined?

Heat pumps are an increasingly popular choice, but how much space do they take up and how big do they need to be?
The main factors that influence the size of a heat pump are the type, size and characteristics of the property and the type of heat pump.

Property factors

It is pretty easy to calculate the size of heat pump that is needed for new-build houses, as new-builds have to comply with certain regulations covering insulation and airtightness. The heat loss level in newer properties is accurate and readily available, as it is calculated at the design stage.

Calculating the levels of heat loss in older properties is more complex. This is because insulation and construction type need to be considered, together with the age and type of the windows and doors, ventilation rates, and the type and size of rooms. The geographical location (altitude and temperatures) also affects heat loss rates, so this needs to be factored in.

Types of heat pumps and sizes

The size of the heat pump differs slightly depending on which type it is. The two most common are air source heat pumps and ground source heat pumps. Ground source heat pumps tend to be slightly bigger and are installed underground.

Typically, homes in the UK will require pumps that are between 4kW and 12kW. As a general rule, the larger the property, the larger the heat pump required.
