Heating and hot water troubleshooting

Sealed system or combination boilers

This type of boiler does not have a water tank.

Water leaks can cause the system pressure to drop. This can stop the system working properly.

Check the pressure gauge. It should be set at 1 bar. A red indicator needle often shows where the pressure should be.

Check your user manual to see if you can re-pressurise the boiler yourself.

If your boiler panel needs tools to remove it, do not touch it and report the repair to book an engineer.
