    At a glance

    Regular servicing, keeping filters clean, and ensuring unobstructed airflow help maintain optimal performance.

    Yes. Well-insulated walls, floors, and roofs reduce heat loss and allow your ASHP to work more efficiently.

    Low-temperature systems such as underfloor heating or larger radiators improve ASHP efficiency and comfort.

    Yes. Using programmable or smart thermostats to control heating schedules prevents unnecessary energy use.

    While colder air reduces efficiency slightly, modern ASHPs are designed to work effectively even in UK winters.

    Air source heat pumps (ASHPs) are an energy-efficient, eco-friendly way to heat your home. However, like all heating systems, their performance can be optimised with the right practices. Here are practical tips for getting the most from your ASHP:

    1. Ensure Proper Installation

    Efficiency starts with installation. A professional installer will size your system correctly, position the outdoor unit with enough airflow, and ensure the refrigerant and controls are optimised.

    2. Regular Maintenance

    Schedule an annual service to check the compressor, fan, and refrigerant levels. Clean filters, remove debris around the outdoor unit, and inspect for leaks to keep your ASHP running efficiently.

    3. Upgrade Your Heating System

    Low-temperature heating works best with ASHPs. Consider larger radiators or underfloor heating to improve heat transfer and comfort.

    4. Improve Home Insulation

    Walls, lofts, floors, and double glazing minimise heat loss, reducing the workload on your ASHP and keeping your energy bills lower.

    5. Use Smart Controls

    Smart or programmable thermostats allow you to schedule heating efficiently, ensuring your home is warm when needed and reducing wasted energy.

    6. Mind the Outdoor Unit

    Keep the outdoor unit clear of plants, debris, snow, or ice. Good airflow is essential for the system to extract heat efficiently.

    7. Monitor Performance

    Some ASHPs come with monitoring apps. Track energy use, temperature, and performance to identify inefficiencies early.

    By following these tips, you can enjoy lower energy bills, a warmer home, and a system that lasts longer, all while reducing your environmental impact.
