Boiler Maintenance Tips

1. Check Leaks

One of the first tips for boiler maintenance is to check for leaks. Make it a necessary part of your routine boiler checkup. It is always better to know if the boiler has any leakage before time, otherwise, it may cause a lot of problems in the future.

During the inspection, make sure all pipes are tight and all valve connections are perfect. Corroded pipes are one of the most obvious reasons that can allow leakage in the boiler. A leak can also happen if the water pressure is too high. Therefore, it is advised to monitor the water pressure through a pressure gauge and use non-corroded pipes in your heating system.

As time passes by, air can get trapped in the radiators. If air is trapped in your hot water system, it will make the boiler produce less heat and reduce the efficiency of your radiators. Your boiler will not work at its full capacity. Moreover, your boiler will be forced to work hard and in doing so, it will consume more fuel.

To make your boiler healthy for the winter season, take a walk through your home and open the air bleed on each radiator. In this way, the trapped air will be released. Also, remember to place a bucket or a container under the valve to catch the water that will come out when the air is released. You can do this all yourself, but if you are confused, we’ll advise you to call a certified gas-safe engineer that will bleed your radiators and help you with boiler maintenance.
