Air source heat pumps (ASHPs) can be an efficient and eco-friendly option for home heating. However, to maximise their benefits, homeowners should be aware of common mistakes and how to avoid them.
1. Installing in Areas Requiring High Heat Output
ASHPs are most effective in homes with lower heating demands. They are ideally suited for smaller homes or spaces with minimal heating requirements. If your home is large or houses many people, an ASHP might struggle to provide sufficient heat. In such cases, alternative heating systems like gas or oil boilers may be more effective, though they lack the renewable energy benefits of ASHPs.
2. Neglecting Home Insulation
For an ASHP to function efficiently, proper insulation is crucial. These systems typically work best with underfloor heating in well-insulated homes. Without adequate insulation, much of the generated heat can escape, making the system work harder and less efficiently. When budgeting for an ASHP, include the cost of any necessary insulation upgrades to ensure optimal performance.

3. Expecting High Performance in Very Cold Climates
ASHPs can operate in temperatures as low as -20°C, but their efficiency decreases significantly as temperatures approach 0°C. In extremely cold climates, ASHPs may struggle to provide adequate heat. Ground-source heat pumps, which extract heat from the ground rather than the air, can be a better option in these environments due to their consistent performance regardless of outside air temperature.
4. DIY Installation
Professional installation of an ASHP is essential. Incorrect installation can lead to poor energy efficiency, inconsistent heating, and potential stability issues. Furthermore, improper installation might void the manufacturer’s warranty. Always hire a certified professional to install your ASHP to ensure it is correctly integrated with your home’s existing systems and performs efficiently.
Conclusion
ASHPs offer a cost-effective and environmentally friendly heating solution, but they come with specific requirements and limitations. Proper insulation, appropriate installation, and realistic expectations regarding their heating capacity and performance in cold climates are key to maximizing their benefits. By avoiding these common mistakes, homeowners can ensure their ASHP operates efficiently and effectively, providing reliable and sustainable heating.
