Heat Pump Maintenance Tips for SW1 High-Value Properties
If you’re using a heat pump in your Belgravia home, you’re already taking an efficient approach to heating. Compared to many other properties in SW1, your system produces fewer emissions and generally needs less upkeep than traditional heating systems.
That said, like any appliance, your heat pump still needs regular checks and servicing to keep it running efficiently and extend its lifespan. Here at WPJ Heating, we can work with you to keep your heat pump in good condition all year. Read on as we share heat pump maintenance tips for your home.
Long-term care
Heat pumps are generally low-maintenance, but they still need occasional attention to keep performing efficiently. A well-maintained heat pump can be up to 25% more energy efficient than one that’s been neglected. Keep these long-term care tips in mind to get the most out of your system:
Clean or replace the filters
Clogged and dirty filters can drastically minimise the airflow of heat pumps, so be sure to keep them clean and replace them when necessary.
Spot-check the heat pump
Regular spot checks will help keep the heat pump in optimum condition. Pay attention to the drain tray and make sure it doesn’t accumulate too much condensate. Otherwise, it could overflow, freeze, and become mouldy.
Refill the antifreeze as needed especially before winter, and keep an eye on your system’s water pressure. For most homes, it should stay between 0.7 and 1.2 bar. Get in touch with us if it falls outside that range.
Look for obstructions
An air-source heat pump uses outdoor air as a heat source. Make sure there’s nothing blocking the unit. Trim nearby grass and remove leaves or debris that could interfere with performance.
Servicing requirements
Regular maintenance will ensure that your heat pump works efficiently and safely. Plus, it helps prevent unnecessary and disruptive breakdowns and repairs. Most high-quality heat pumps will last an average of 20 years, but regular maintenance might extend that for decades.
Pre-season prep
We recommend calling us for heat pump maintenance and checks in the summer months. This will ensure that your system is running safely and effectively in time for the colder months. Our team will also remove any debris and dirt from the fan blades, coils, and other components.

Professional maintenance
Annual servicing gives your heat pump a full check-up to ensure everything’s working as it should. We recommend calling us during the summer or early autumn to make sure your appliance is ready for the heating season. Regular servicing helps catch potential issues early and gives you peace of mind, knowing everything is running efficiently before winter sets in.

Take control
Modern heat pumps often come with digital remotes, mobile apps, or smart home integrations that make them easy to manage.

If there are any issues, contact our Gas Safe heating engineer. We’ll identify the problem and fix it promptly. We’ll also check that the hot water controls are working as scheduled so your system runs exactly the way it should.
