What’s The Difference Between Air Source and Ground Source Heat Pumps?

With the cost of living rising, many households and businesses are looking at energy-efficient ways to heat their properties. One method currently proving popular is using air or ground source pumps.

But what are they, and what’s the difference between air source and ground source heat pumps? Below, we explore each and how they can benefit your home.

What are air source heat pumps?

Air source heat pumps are an energy-efficient and low carbon way to heat a property. The pump is installed outside and absorbs the air and converts it into heat. Air absorbed from the environment is transferred to a fluid and compressed, and this feeds into a central heating system, which moves the heat around your home. It doesn’t matter how cold it is outside either, as this system can still take warmth from the air, even at -25 degrees Celsius.

What about ground source heat pumps?

Similar to air source heat pumps, ground source pumps are also a low-carbon way to heat a home. This pump works using a horizontal or vertical pipe, also known as a ground loop, which absorbs the heat from the ground. This pipe is buried underground and contains a fluid which transfers the heat from the ground, which the pump converts to heat for the home.

Air vs ground source heat pumps – what’s the difference?

The main difference is how each pump absorbs the warmth in the surrounding environment. One is via the air and the other from the ground heat.

Another difference between air source and ground source heat pumps is installation costs. Ground source heat pumps require extensive installation and ground work which means a higher labour and time cost.

Which heat pump is best for you?

So, which heat pump is the best for your property? There are pros to each, as detailed below:

Benefits of an air source heat pump

Suitable for most homes

Air source heat pumps don’t take up too much space. So most properties can install them without the pump getting in the way of outdoor areas.

Low maintenance cost

Air source heat pumps require regular servicing to keep the unit in the best working order. However, annual servicing is affordable and will help you save money over its lifespan.

Access to installation grants

If you’re thinking of switching to an air source heat pump, the current Boiler Upgrade Scheme may help you access grants of up to £5,000 towards installation costs.

Benefits of a ground source heat pump

The main advantages of a ground source pump include:

• Long life span (around 25 years)
• Installation grants available
• Good efficiency all year round

However, there are a few disadvantages, such as:

• Higher installation costs
• Outside space needed for pipework
• Efficiency can be affected by soil type
• Internal space need for a sizeable fridge-sized unit
