Water Level

The water level of the boiler should be checked every fortnight as boiler that run without water can be damaged beyond repair.

Excessive lime-scale in the boiler is usually the result of hard water and this can prevent the boiler from working as efficiently or as it should. The heating capabilities of the boiler will be hampered if lime-scale continues to build, so it’s important to deal with us to get the most from your boiler. If you notice a build-up of lime scale within, make sure you carry out a thorough descaling job.

Air Vents

The boiler efficiency can also be reduced by any blocked air vents and this is especially the case for gas boilers. Blockages are almost always caused by dirt that builds up in the vents. You should inspect vents and flues on a regular basis to ensure no blockages have occurred as this will improve the efficiency of your boiler. Clearing the blockage will result in free passage for air to flow through the vents once again.

Dust Build-Up

As the boiler continues to operate, dust can start to build up from within. This accumulation needs to be dealt so it’s important to check the boiler room on a regular basis for any signs of dust build-up. Dust can go as far as preventing the boiler system from working coorr4ectly as it build up in the specific parts, with the fan being one of the many parts of the boiler that attract the most dust. Optimal efficiency can be achieved by clearing dust from any parts of the boiler, including the fan.


Leaks can occur at any time so its difficult to pinpoint exactly when you should carry out a thorough assessment for leaks. You should look out for any signs of gas or fuel leaking from the valves connected to the boiler. Adjustments may well be necessary in the system itself if you spot any sign of a leak. A repair or replacement job may even be necessary if the leak is a result of damaged parts.
