As winter nears, it’s important to make sure your heat pump is ready to handle the colder weather and keep your home warm. Ground and air source heat pumps are highly efficient heating systems, but like any appliance, they require regular care and maintenance for optimal performance, especially in the winter months when they are under more strain.
Book a service well in advance to ensure your heat pump operates effectively throughout winter. Clean the external heat pump unit, adjust thermostat settings, and check air filters regularly to maximise energy efficiency during the cold weather ahead.
A proactive approach not only helps keep your home warm but also ensures more energy-efficient operation, which is good for both your wallet and the environment.

Importance of heat pump maintenance in time for winter
Nobody wants problems with their central heating and hot water in the depths of winter. So it’s so important to take care of your air source heat pump system and keep it regularly maintained. Neglecting your heat pump can lead to poor performance, reduced heat output, higher energy costs, and system breakdowns.
Heat pumps work by absorbing heat energy from the outside air or ground, even in colder temperatures. They transfer heat to an underfloor heating or central heating system to provide warmth and hot water.
However, heat pump efficiency naturally dips in winter as the air and ground temperature lowers, leading to higher energy consumption. Maintenance and proper care are essential to ensure your heat pump is working its best and to avoid higher energy bills.
Regular servicing and care will also help prolong the lifespan of your heat pump and protect your investment.
Do air source heat pumps need protection in the winter months?
The outdoor unit is particularly vulnerable to cold weather conditions, which can damage it and lead to reduced performance or even complete failure.
To protect your heat pump system, keep the external unit clear of snow, ice, and debris such as leaves. Snow accumulation can block the airflow around the unit, forcing the system to work harder to extract heat from the outside air. This can lead to increased energy consumption and a decrease in overall efficiency. Also, ice build-up on the heat pump unit can damage the coils and other components, leading to expensive repairs.
Many modern heat pumps are equipped with a defrost cycle to handle minor ice build-up, but it’s still important to keep an eye on the unit during harsh weather conditions. A canopy or specially designed cover can also help prevent issues by protecting the unit from direct snow and rainfall.
Ways to prepare your heat pump for winter
Here’s Cinergi’s guide to getting your heat pump winter-ready.
Check for system alerts
Some newer heat pumps have diagnostic systems that send alerts if something isn’t working properly. Make sure you check for alerts regularly to catch any issues early.
Clean your heat pump regularly
Keeping your heat pump clean is essential for maintaining efficiency. Dust, dirt, and debris can accumulate on the outdoor heat pump unit, restricting airflow and reducing performance.
Before winter sets in, clean the outdoor unit and the surrounding area to remove any leaves and other debris that has gathered during the autumn.
Inside, clean the air filters regularly. Clogged filters restrict airflow, forcing the system to work harder to maintain a consistent temperature. We recommend replacing or cleaning filters every one to three months.
Before cleaning any part of your heat pump, turn the power off first and wear gloves.
Schedule servicing and maintenance
Having your heat pump serviced before winter is one of the best ways to ensure it works properly. Book an MCS-accredited engineer to perform a thorough inspection of both the heat pump’s indoor and outdoor elements, checking for any potential issues.
A professional heat pump service includes examining the heat exchanger, heat pump controls, refrigerant levels, and the defrost cycle to ensure everything is working properly.
Regular maintenance not only helps to identify and fix potential problems before they escalate but also ensures that your heat pump operates at peak efficiency, reducing energy consumption and helping to keep your heating bills in check.

Check the air vents and filters
Checking the air vents and filters is another crucial job in preparing your heat pump for winter. Dirty vents can block airflow, reducing the efficiency of your heating system. Make sure the vents are clean and unblocked, and check the filters regularly to ensure they are not clogged with dust and debris.
Adjust your thermostat settings
As the temperature drops, adjusting your thermostat settings is essential to ensure your heat pump operates efficiently. Heat pumps are designed to provide energy-efficient heating, but they work best when the temperature is set at a consistent level.
Avoid drastic changes in temperature settings, as this can cause the heat pump to work less efficiently. Instead, set your thermostat to the desired temperature and maintain that setting throughout the day. Some heat pumps have specific winter settings to optimise performance during colder weather. Ask your installer if you’re unsure about your thermostat settings.
Proper insulation
To get the most out of heat pumps, a property must be well insulated. Before the chill sets in, check your loft insulation, fit double-glazed windows to older properties, seal draughts, and consider cavity wall insulation.
Do heat pumps need to be covered in winter?
Covering your heat pump during the winter is generally not recommended. While it might seem logical to protect it from snow and ice, covering the unit can restrict airflow and trap moisture inside, leading to corrosion and damage.
Most heat pumps are designed to withstand winter conditions, so long as they are kept free of excessive snow and ice, they shouldn’t need a cover.
That said, if you live in an area prone to heavy snowfall or extreme winter conditions, you can consider installing a specially designed heat pump cover. These covers allow for proper airflow while protecting the unit from snow. Another option is to build a shelter or awning over the unit to protect it from direct snowfall without restricting airflow.
How to prepare a ground source heat pump for winter
Start by checking the antifreeze levels in the system to prevent the ground loop from freezing, as this could lead to system failure. Inspect the heat pump’s filters and clean or replace them to maintain good airflow and efficiency.
It’s vital to book a professional maintenance check to ensure the system is in good working order.
Other top tips for reliable heating this winter
In addition to keeping your air source heat pump in good condition, there are a few other essential jobs to ensure reliable heating and hot water this winter.
- Before it gets too cold, switch your central heating on to test it.
- If you have a gas boiler in addition to a heat pump, make sure it’s serviced in good time.
- If you have a traditional central heating system, be sure to bleed your radiators thoroughly.
- Wrap external pipes to stop them from freezing and potentially bursting.
- Check your hot water cylinder for leaks and make sure it has proper insulation.
- Check your home’s insulation and upgrade it if necessary.
- If your home is poorly ventilated, consider replacing old vents, perhaps with a Mechanical Ventilation Heat Recovery (MVHR) system.
Conclusion
Properly caring for and maintaining your heat pump is essential to ensure your central heating system or underfloor heating is reliable all winter. By following the steps outlined above – cleaning your heat pump regularly, scheduling maintenance, checking air vents and filters, and adjusting thermostat settings – you can ensure optimal performance and keep your energy bills in check.
