RightAir Solutions is a company that specialises in commercial air conditioning services.
Choosing between an air source heat pump and a ground source heat pump depends on several factors including your property’s layout, your budget, and long term energy efficiency goals. Air source heat pumps extract heat from the air outside to heat your home and provide hot water, while ground source heat pumps take advantage of the consistent temperature underground. Ground source systems generally deliver higher efficiencies and lower running costs but require more space and a greater upfront investment. In contrast, air source systems are quicker to install and often better suited for urban properties where space is limited.
With rising energy bills and the UK Government’s push towards achieving net zero emissions, many homeowners in London are looking for cleaner alternatives to gas boilers. Heat pumps are an effective solution because they use renewable energy, either from the air or the ground, significantly reducing carbon footprints.
Pro Tip: Always check if your current radiators are compatible with lower flow temperatures from heat pumps. Upgrading them can significantly boost your system’s efficiency and lower running costs.
Selecting the most appropriate system is important for achieving comfort, energy efficiency, and cost savings. RightAir Solutions offers expert guidance to help you make the right choice, ensuring that your installation is seamless and optimised for your property’s specific needs.
An air source heat pump absorbs heat from the outside air and boosts it to a higher temperature using a compressor and refrigerant cycle. This heat can then be used for radiators, underfloor heating systems, or domestic hot water.
Air to Air Systems: Transfer heat directly into the indoor air via fans. Suitable for homes without existing wet central heating systems.
Air to Water Systems: Transfer heat into a wet central heating system and are ideal for providing both heating and hot water.
A ground source heat pump uses a network of pipes buried underground to extract stored solar energy from the soil. This low-grade heat is then upgraded to a useful temperature for home heating and hot water.
Horizontal Ground Loops: Laid in trenches and require a significant amount of land area.
Vertical Boreholes: Drilled deep into the ground, making them suitable for smaller plots where space is limited.
RightAir Solutions helps you install high-efficiency heat pumps supported by government grants. Future-proof your home today.
Air source heat pumps are generally less efficient during colder months because colder air contains less heat energy. Ground source heat pumps maintain a more consistent efficiency year-round because underground temperatures remain relatively stable.
A ground source heat pump typically has a COP of around 3.5 to 4.5, meaning it produces 3.5 to 4.5 units of heat for every unit of electricity used. An air source heat pump usually has a COP of between 2.5 and 3.5, depending on outdoor temperatures.
It is important to note that heat pumps are more than three times more efficient than traditional gas boilers. However, because electricity is currently around four times more expensive than gas, your choice of electricity tariff and system control can have a significant impact on running costs.
Air source heat pump installation is less invasive and can usually be completed within a few days. The unit is installed outside the home and connected to the existing central heating system. Most installations are considered permitted development, meaning planning permission is generally not required, although it is worth checking with local planning departments, especially for listed buildings or conservation areas.
Ground source installations are more complex. They involve significant groundwork to install either horizontal loops or boreholes. After the groundwork, the internal heat pump unit is fitted, much like a traditional boiler.
An air source heat pump typically costs around £14,000 including installation, depending on the size of the heat pump, the property size, and whether any upgrades to radiators are needed. Ground source heat pumps remain more expensive, with total installation costs often ranging from £13,000 to £20,000.
Ground source heat pumps usually have lower running costs because of their higher efficiency. Air source units may cost more to operate during colder months. Both systems require regular servicing to maintain efficiency, although ground source systems tend to have lower maintenance needs after the initial installation.
You could save more money over time by choosing a suitable electricity tariff and ensuring that radiators and heating systems are correctly sized for optimal efficiency.
Ground source heat pumps generally produce fewer carbon emissions over their lifespan because they use a stable and more efficient energy source. Air source heat pumps also significantly reduce carbon emissions compared to traditional gas boilers, especially when powered by renewable electricity.
At RightAir Solutions, we help our customers access available grants through the UK Boiler Upgrade Scheme to make their green transition more affordable.
These units need adequate space outside the home with good airflow around the outdoor unit. They are compact and ideal for urban homes.
Horizontal loop systems require a large garden or field, while vertical boreholes require only a small footprint but involve drilling equipment.
Typically, an air source heat pump will last between 10 and 15 years, depending on how well it is maintained.
Ground source heat pumps have a longer life expectancy, often exceeding 20 years for the internal unit and more than 100 years for the underground pipework.
Air source heat pumps are noisier due to their outdoor fans and compressors. Modern models are designed to be much quieter, but their noise might still be noticeable in densely populated areas. Ground source systems are quieter because the noisy components are housed indoors.
Both air source and ground source heat pumps are eligible for grants under the Boiler Upgrade Scheme in England and Wales. RightAir Solutions can help you navigate the application process and maximise your savings.

| Feature | Air Source | Ground Source |
|---|---|---|
| Upfront Cost | Lower | Higher |
| Running Costs | Higher | Lower |
| Installation Complexity | Easier | More Complex |
| Space Requirement | Minimal | Significant |
| Lifespan | 10-15 years | 20-25 years |
| Efficiency in Winter | Reduced | Consistent |
Think about your available space, your budget, and how long you plan to stay in your home. If you have enough land and can afford a higher upfront cost, a ground source system could offer better savings and efficiency over time. If you need a quicker, less disruptive installation, an air source heat pump may be the best fit.

For smaller properties or flats, an air source heat pump is usually the best choice due to its compact size and simpler installation requirements.
Yes, ground source heat pumps maintain consistent efficiency even during very cold periods because the underground temperature stays stable compared to fluctuating air temperatures.
While the initial groundwork can be intensive, once completed, the indoor unit installation is no more disruptive than fitting a traditional boiler.
Modern air source heat pumps are quieter than older models, but ground source heat pumps offer the quietest operation since their main components are located inside the property.
Yes, both air source and ground source heat pumps can significantly lower your annual heating bills, especially when combined with government grant support schemes.
