Wall-mounted boilers are a great way to heat your home and provide hot water on demand. However， like all appliances， they require regular maintenance to ensure that they continue to run smoothly. Here are some common wall-mounted boiler maintenance tips to keep in mind:

1. Check for leaks: The first thing you want to do is check for any leaks around the boiler. Look for signs of water damage， such as discoloration or swelling of walls， floors or ceilings. If you do find a leak， turn off the water supply and call a professional plumber.

2. Clean the boiler: It is important to clean your boiler at least once a year to ensure that it continues to function properly. Use a soft brush to remove any dust or loose debris from the boiler's exterior. Make sure to also clean the internal components of the boiler with a soft brush or vacuum cleaner.

3. Test the pressure: Check the pressure gauge on the boiler to ensure that it is at the appropriate level. If the pressure is too low， you may need to add more water. If it is too high， you will need to release some pressure by bleeding the radiators.

4. Check the pilot light: Make sure that the pilot light on the boiler is burning constantly. If it goes out， relight it immediately. If the pilot light keeps going out， there may be a problem with the gas supply or the thermocouple.

5. Bleed the radiators: Finally， bleed the radiators in your home to ensure that they are working properly. This involves releasing any air that has accumulated in the system， which can cause your radiators to make noises or not heat up properly.

By following these simple maintenance tips， you can keep your wall-mounted boiler in good working condition and extend its lifespan. If you have any doubts or concerns about the safety or operation of your boiler， call a professional plumber for assistance.
