Boiler Maintenance Tips

A boiler.

Boiler maintenance is a must if you hope to have your boiler efficient at all times. Boilers give a vital service in hot water supply and household warming. They add to the comfort level of the home. Too often, repairs become necessary when the boiler malfunctions.

Regular maintenance can help avert ceaseless repairs. This will help you save on overall costs. Maintenance is advised to avert accidents and boost household safety. Maintenance will also boost the efficiency of your boiler and extend its life span. Below are some maintenance tips.

Air Vents and Flues

Blocked air vents hamper the boiler from working efficiently. This particularly applies to gas boilers. Dirt may accumulate in vents or flues and cause a blockage. It is a good idea to inspect vents and flues regularly. If any blockage has occurred, clear it to allow free passage of air.

Water Level

It is vital that you check the boiler water level every fortnight or so. Should the boiler operate without water, this can easily damage it beyond repair. It can also cause an accident and endanger the lives of family members. Be sure that the pilot light is on as you check the water level. If the water level is below the minimum, you need to check the plumbing and correct any faults. Sometimes, all that is required is a few minor adjustments in the set-up.


These may occur during normal usage of the boiler. Gas or fuel may leak through the valves. This usually indicates some adjustments are necessary to the system. If you detect damaged or worn out parts, this calls for repair or replacement.


Hard water usually gives rise to excessive lime-scale in the boiler. This prevents the boiler from working as it should. If left to accumulate, lime-scale will hamper the heating capacity of the boiler. You will need to de-scale your boiler should you notice too much lime-scale within.


Regular lubrication is essential for the smooth operation of most mechanical systems. Your boiler will benefit from routine lubrication, as this will support its working capacity. Be sure to lubricate boiler parts that are frequently in motion such as the fan and pumps.

Clear Dust

Dust easily accumulates in the boiler room because of the boiler operations. Check the boiler room regularly and clear any dust in sight. Pay particular attention to the boiler parts as dust accumulation will affect the system from working well. The fan often develops much dust build-up. Be sure to clear all dust to enable optimal efficiency.


It is a good idea to clear all the water from the boiler a couple of times in a year. It is best to do so after the winter when the boiler works at full capacity. Dirt, grit, and lime-scale tend to accumulate in the boiler. Flush out all water from the boiler and clean the interior thoroughly. Place in some new gaskets before you refill the boiler.

Annual Check

It's a good practice to have your boiler checked at least once a year by a registered engineer. This will ensure safety and efficiency. Any emerging problems can be noted and dealt with accordingly. A safety certificate is usually issued after inspection.
