The Essential Boiler Maintenance Checklist

1. Schedule Regular Servicing

Annual boiler servicing by a qualified engineer ensures all components are working correctly. It helps to detect any potential issues early and prolongs the boiler’s lifespan. Check out our detailed troubleshooting guide for common boiler issues.

2. Monitor the Pressure

Regularly check the boiler pressure. It should be between 1 and 1.5 bars when the system is cold. Low pressure can impact heating, while high pressure can damage the system. Refer to your boiler manual for specifics.

3. Check the Flue

Ensure the boiler flue is clear and not obstructed by debris or vegetation, especially if it exits through the roof or wall. Our article on installation tips for boiler with flue systems provides helpful information.

4. Bleed the Radiators

If you notice cold spots on radiators, they may need bleeding. It releases trapped air that can prevent the heating system from working efficiently.

5. Inspect for Leaks

Check for any signs of water leaks around the boiler. Leaks can cause significant issues if left unchecked.

6. Test the Controls

Ensure that the thermostat and timers are working correctly. They play a crucial role in maintaining efficient heating cycles.

7. Power Flush the System

Every few years, consider a power flush to remove sludge and debris from the system. It helps maintain efficiency and reduces the risk of breakdowns.

Considering a New Combi Boiler?
