Winter Heat Pump Care Guide
Keep Your Heat Pump Running Smoothly This Winter
As more UK households embrace renewable heating systems, it’s natural to ask how well air source heat pumps handle winter weather. At Eaasy Heat, we want to ensure our customers are confident in the performance of their system, even when temperatures drop.
Here’s your complete guide to caring for your air source heat pump in the winter months, with practical tips to maximise performance and reliability.
Do Heat Pumps Still Work in Winter?
Absolutely. Air source heat pumps operate in winter the same way they do year round, by extracting ambient heat from the air and transferring it into your home. Even in cold weather, the system continues to draw energy from the air, providing both heating and hot water.
In the UK, typical winter temperatures range from 2°C to 7°C. While your heat pump may use more energy during this time to meet demand, modern systems are built to handle cold conditions efficiently. It’s rare for temperatures to fall low enough to impact performance.
What If My Heat Pump Looks Frozen?
Frost or even a light coating of snow on your outdoor unit is normal. At Eaasy Heat, the systems we install are tested for performance in cold climates, including snow, rain and high winds.
The air source heat pumps we fit include automatic defrosting cycles that kick in when needed. You may see some steam or water dripping from the unit during this process, this means the system is working as it should.
Schedule an Annual Service
Regular maintenance ensures your heat pump performs at its best all year round. Our certified engineers can carry out full checks before and during winter, including:
- Visual inspection of the unit and components
- Pressure and temperature checks
- Leak detection and diagnostics
- Electrical circuit testing
- System optimisation and control setup
This service helps extend the lifespan of your heat pump, maintain efficiency, and ensure continued warranty coverage.
Insulate External Pipework
Adding insulation also known as pipe lagging, around any exposed pipes helps retain heat, improve system efficiency, and prevent freezing. It’s a quick and affordable step that keeps your system running smoothly even in colder areas.
Good pipe insulation reduces heat loss, keeps your hot water hotter for longer, and reduces strain on your heat pump during peak usage periods. Our engineers can advise on the best materials during your service.
Keep the Outdoor Unit Clear
Leaves, snow, branches and general garden debris can block airflow and reduce efficiency. Regularly check around the unit and gently clear anything that’s gathered nearby. Always switch off the system before doing any cleaning.
Avoid using hot water or sharp tools to remove frost, your unit is designed to defrost itself. If you suspect a malfunction, contact our support team.
Add a Protective Cover (If Needed)
A canopy or purpose-built heat pump cover can offer extra protection from falling debris and snow, especially if your garden is heavily exposed. If you choose to use a cover, ensure it’s designed to allow full airflow and ventilation. Ask the Eaasy Heat team about suitable options.
Consider a Snow Spacer
In areas with frequent snowfall, snow spacers can lift the unit higher off the ground, reducing the risk of snow build-up or water pooling. These are typically installed at the same time as your heat pump but can be planned ahead for replacements or new installs.
Your heat pump is built to perform all year round. With a few simple checks and some preventative care, you’ll enjoy consistent heating, even on the frostiest days.
