Heating Your Home Sustainably:
Understanding Air and Ground Source Heat Pumps
At AS Mechanical & Electrical Ltd, we specialise in providing sustainable heating solutions using air and ground source heat pumps. These innovative technologies harness the sun’s heat as a renewable energy source, providing efficient heating and hot water for residential properties. In short, they are the solar panels which work night and day!
We often get asked how heat pump technology works, so we’ve provided you with summary below to hopefully answer some of those questions and explore the advantages and disadvantages of both. If you’d like to explore this further, then please contact us and we’ll be happy to discuss your project with you.
Types of Heat Pumps
We installed a complete turnkey heat pump solution in the New Forest
Air Source Heat Pumps
Air source heat pumps extract heat from the outside air, even in cold temperatures, and use it to warm your home and produce hot water. The process involves heat absorption from the outdoor air, compression, heat release to the internal gas to the water heat exchanger, and expansion. While efficient during milder seasons, it's important to note that the output and performance of air source heat pumps can vary depending on the outside air temperature. Depending on the chosen product, the efficiency may be reduced in freezing weather, necessitating backup heating elements.
Ground Source Heat Pumps
Ground source heat pumps, also known (generally incorrectly) as geothermal heat pumps, utilize the relatively constant temperature of the ground to extract and distribute heat. A ground loop system buried in the ground absorbs heat, which is then transferred to the internal gas-to-water heat exchanger for heating and hot water through a compression and distribution process. Ground source heat pumps offer more stable and consistent performance throughout the year and are less affected by external temperature fluctuations.
Advantages and Disadvantages of
Air Source v Ground Source Heat Pumps
Air Source Heat Pumps
Advantages:
- Easier and less expensive installation.
- Suitable for a wide range of properties, including those with limited outdoor space.
- Versatile, providing both heating and cooling.
Disadvantages:
- Reduced efficiency in extremely cold weather.
- Additional heating elements may be required in freezing conditions.
- Outdoor unit noise may be a consideration in residential areas.
Ground Source Heat Pumps
Advantages:
- Consistent performance in varying weather conditions.
- Higher efficiency in extreme cold temperatures.
- Long lifespan with minimal maintenance.
Disadvantages:
- Higher upfront installation costs.
- Requires sufficient outdoor space for ground loop installation.
- Installation complexity may be higher compared to air source heat pumps.
Financial Incentives
Installing air or ground source heat pumps in the UK offers significant financial advantages. The UK government's Boiler Upgrade Scheme provides a grant of £7500 for homeowners looking to switch to renewable heating solutions. This grant aims to incentivize the transition from traditional heating systems to eco-friendly alternatives, making sustainable heating solutions more accessible and affordable for homeowners.
Summary
Whether you opt for air-source or ground-source heat pumps, both offer sustainable and energy-efficient heating solutions. The financial incentives provided by the UK government, such as the Boiler Upgrade Scheme, make these technologies even more appealing, encouraging a shift toward eco-friendly heating solutions for a greener and more sustainable future.

Heat Pump Installation FAQ’s
-
This is a question that can only really be answered once we understand your property and circumstances. Speak to one of us and we’ll only be too happy to help you!
-
The short answer is, generally, yes. If you have a conventional boiler based system it was probably designed to work at a much higher temperature than a heat pump system would be designed at. Because the water is cooler the emitters need to be larger. Using a high-temperature heat pump design should be a last resort.
-
Provided they are installed correctly, connected to an appropriate distribution system and operated correctly, heat pumps can offer a considerable cost saving over oil, LPG and direct electrical heating. As part of the process we can model the likely running costs for you, for peace of mind.
-
Installing a heat pump begins with a thorough assessment of your property to determine the appropriate system type and size. Detailed planning follows, including selecting the ideal location and integrating the heat pump with existing heating systems, which may involve necessary alterations. Installation involves positioning the outdoor unit (for air source heat pumps) or laying ground loops (for ground source heat pumps), alongside indoor component installation. Testing ensures proper operation before handover, where you'll receive training on system use and maintenance. Ongoing support and maintenance are provided to maximise efficiency and longevity.

In the UK, rules for planning permission regarding heat pumps vary based on factors like the type of pump, property location, and extent of alterations. Permitted development rights may apply for certain installations, but limitations and conditions, such as size and location, must be adhered to. Properties in conservation areas, national parks, or listed buildings may face additional restrictions. While small-scale air source heat pumps (ASHP) may often be permitted developments, larger ASHP or ground source heat pump (GSHP) installations, involving significant alterations like excavation, are more likely to require planning permission, especially in protected areas. Considerations include noise levels, visual impact, and compliance with building regulations. For specific guidance tailored to your situation, feel free to contact us for a consultation.
