How Big Is An Air-Source Heat Pump?

If you plan to install an ASHP in your home or office, you may wonder how big an air-source heat pump is.

Choosing the right size to fit your space before installing an air-source heat pump in your home will allow easy maintenance and installation.

Selecting the right size is crucial not only for efficient heating and cooling but also for maximizing savings.

If your air-source heat pump is too small, it will run longer to meet your space’s heating and cooling needs, leading to high electric bills. 

On the other hand, if it’s too big, it will have a frequent operating cycle, which reduces efficiency, damages the motor, and shortens the heat pump’s usual lifespan. 

In this article, you will learn about the typical sizes available for air-source heat pumps and how to estimate the size and capacity needed for your system.

What Is The Size Of An Air-Source Heat Pump?

Air source heat pumps are a type of heating system that can provide warmth to your home and are available in different types and sizes. 

Typically, they are about the same size as a washing machine(1-1.5 m H, 0.5-1m W) and weigh as much as an average person(60-100kg). 

Two types of air source heat pumps are monobloc and split systems.

Monobloc systems have all the parts in a single outdoor unit, while split systems separate the parts between indoor and outdoor units.

In the UK, the most common sizes of air source heat pumps are: 

  • 4kW
  • 5kW
  • 6kW
  • 8kW
  • 10kW
  • 12kW

If you live in a large or poorly insulated property, consider purchasing a larger air source heat pump, such as 12kW or 16kW. 

On the other hand, if you own a smaller home, a 5kW pump may suffice.

For example, a 17kW air-source heat pump that weighs up to 120kg is ideal for fulfilling the heating and hot water needs of a 4-8 bedroom detached or semi-detached house. 

In comparison, a smaller 5kW model weighing 58.5kg is generally sufficient for heating a flat or 100m² house.

Calculating The Right Air-Source Heat Pump Size 

Determining the appropriate size for a heat pump can be a complicated process, and it is recommended to seek the assistance of a professional. 

However, before contacting an expert, you can take some steps to prepare and estimate the size you will require. 

For instance, in winter, you can reduce the flow temperature of your boiler to see how your property handles it. If it works well, you are most likely prepared for a heat pump. 

It is also essential to insulate your property as much as possible to minimise the size of the required heat pump. If your property is poorly insulated, you will likely need a larger heat pump than a well-insulated one. 

Additionally, ensure you have enough outdoor space to accommodate the heat pump and a one-meter by one-meter space inside your home for a hot water cylinder. 

Remember that the air-source heat pump size you require for your home will ultimately depend on outdoor design temperature, desired room temperature, and flow temperature. 

Although experts suggest you need 1kW for every 10 square meters, this calculation is not limited to this since factors, such as the number of people in your home and their preferred temperature levels, can also affect the size of the heat pump you will require. 

Once again, while it is possible to estimate the size of the heat pump you will require independently, it is best to seek professional assistance to ensure you get the correct size for your home.
