Air source heat pumps (ASHPs) are installed across Warwickshire, Leicestershire and the West Midlands as a clean, efficient way to heat homes and businesses. However,…

    Why you can trust our content

    We know that the solar industry is full of misinformation, but we only use reliable sources, including:

    • Trusted solar specialists delivering tailored, careful installations
    • Our proprietary database of solar, ashp and battery system designs
    • Authoritative bodies like MCS and the UK government

    At a glance

    Today’s heat pumps can efficiently extract heat from the air even when it’s below 0°C. They are widely used in colder climates like Scandinavia and Canada, proving they are more than capable in UK winters.

    Air source heat pumps work well in older homes too, especially with good insulation. A professional installer can assess and recommend any upgrades needed to maximise efficiency.

    Most ASHPs operate at around 40–50 decibels, similar to a standard refrigerator. Advanced noise-reduction technology ensures they run quietly, without disturbing you or your neighbours.

    While the initial investment can be high, ASHPs are up to 400% efficient – meaning you get 4 units of heat for every 1 unit of electricity. This leads to lower bills, and government grants can help offset installation costs.

    A professional survey ensures your system is correctly sized for your property. With the right setup, an ASHP can heat the entire house comfortably, even on cold days.

    Air source heat pumps (ASHPs) are installed across Warwickshire, Leicestershire and the West Midlands as a clean, efficient way to heat homes and businesses. However, as with any new technology, myths start to circulate making people unsure about available products and what they can do. Let’s tackle some of the most common questions about air source heat pumps and provide solid answers to help you decide if the technology is right for you..

    Do Air Source Heat Pumps Work in The UK?

    One of the most widespread myths about air source heat pumps is that they are not effective in cold weather. While it’s true that ASHPs extract heat from outdoor air, modern pumps are designed to operate efficiently even when temperatures drop below freezing. In fact, air source heat pumps have been installed successfully in many colder countries, including parts of Scandinavia and Canada, proving that they can handle the demands of British winter weather.

    Are Air Source Heat Pumps Only Useful for New-Build Homes?

    A common misconception is that air source heat pumps are only suitable for brand-new homes. While ASHPs are a great addition to modern, well-insulated properties, they can also be successfully installed in older buildings. In some cases, minor insulation upgrades may be recommended to enhance efficiency, but with the right planning, an air source heat pump can provide cost-effective heating to a variety of building types.

    How Noisy Are Air Source Heat Pumps?

    If you’re worried that installing an air source heat pump will lead to constant background noise, put your mind at ease. The latest heat pumps have been designed with noise reduction technology. Most pumps produce a level of sound that is comparable to a refrigerator, and units are quiet enough to be installed discreetly without disturbing the homeowner or surrounding neighbourhood.

    How Expensive Are Heat Pumps to Run?

    The idea that air source heat pumps are expensive to run is a common concern. While it’s true that installing a heat pump has upfront costs, the long-term energy efficiency they offer can lead to significant savings on energy bills. By transferring rather than generating heat, ASHPs can achieve efficiencies of up to 400%, meaning they use far less energy than conventional heating systems. Over time, the reduction in energy bills offsets the initial cost, making ASHPs an economical choice in the long run. And with Government grants available to help with the cost of installation, heat pumps are home investments well worth making.

    Do They Provide Enough Heating for the Whole House?

    With the correct system size and set up, an ASHP can heat an average property comfortably. As part of the consultation, measurements of the home are taken to ensure the right heat pump is fitted to provide adequate heating for the property.

    How Disruptive is Installation?

    While installing an air source heat pump does require some adjustments, the process is usually straightforward and completed within a few days. Compared to other heating systems, fitting an air source heat pump is often less invasive, as it doesn’t involve extensive changes to your existing infrastructure. Working with an experienced installer ensures the process is efficient and minimally disruptive.

    Can ASHPs Work with Radiators?

    It is often assumed that air source heat pumps only work with underfloor heating systems. While underfloor heating is a great match for an ASHP, the pumps can also be used with radiators, provided they’re the right size for the lower temperatures produced by the pump. In many cases, your current radiators may still work, or they may need minor adjustments to achieve the best efficiency with the heat pump. 

    How Long Will It Last?

    On average, a gas boiler lasts 12 to 15 years, whereas a properly-maintained air source heat pump should work well for 20 years or more. 

    To Sum Things Up

    Air source heat pumps are a reliable, efficient and environmentally friendly way to heat a home.
