Boiler Maintenance Checklist

As the seasons change, the way you operate and use a boiler changes. This unit works extra hard during the winter. Therefore, it is important to inspect your boiler to make sure all components are working seamlessly. Annual service helps prevent explosions, fires, and carbon monoxide poisoning. There are other benefits of boiler maintenance, such as: 

 – It’s cost-effective in the long term 

– Reduce energy bills 

– Prevents winter breakdowns  

 In addition, taking care of your boiler will improve its efficiency and longevity. Note that a well-functioning unit will play a vital role in fulfilling your needs. Below is a boiler maintenance checklist: 

 Check Inhibitor Levels

 Boilers have a central heating Inhibitor that protects the unit from faults and blockages. The right level of inhibitor will make your system work efficiently and prolong its lifespan. In addition, this essential ingredient prevents corrosion and the formation of magnetite. It is extremely easy for Aquatek plumbing and heating engineers to check inhibitor levels at every annual boiler service.  

 Inspect Radiator Valves

 The main objective of a radiator valve is to regulate the heat output from the system’s radiators. It is a good idea to evaluate the efficiency of radiator valves before the winter. There is a wide range of radiator valves; therefore, changing these components require professionalism. Homeowners should invest in expert boiler engineers.  

 Boiler Ventilation

 The location of your boiler is an important aspect that you should consider when purchasing this unit. The ideal location should have no debris or other contaminants that can compromise the functionality of your system. During maintenance sessions, you should make sure the air vents of your unit are free from debris and other pollutants. In addition, compartments where boilers are situated, should not be used for storage of combustible materials. This is a safety precaution to prevent the risk of boiler explosion.  

 Radiator Bleeding

 Radiator bleeding is an essential maintenance tip, especially before the autumn and winter seasons. It involves a thorough step-by-step process of releasing trapped air from the radiators. There are various signs that a radiator needs bleeding: 

 – Mildew on the walls 

– Gurgling noises from the unit 

– The top of the radiator is cold 

– The entire radiator is cold 

The best way to identify a radiator that needs bleeding is by checking for cold patches at the top of the system. To keep your boiler healthy, you should bleed the radiators at least twice per annum.  

 Inspect the Burner Flame

 A malfunctioning burner flame will produce a yellow flame. On the contrary, a healthy boiler should produce a blue flame. Therefore, it is important to inspect the burner flame from time to time. The yellow flame comes as a result of incomplete combustion due to the presence of carbon monoxide.  

 Examine the Condensation Drain Line

 The main aim of a condensation drain in a boiler is to get rid of excess water. You should examine the drain line for blockages. A clogged drain will compromise the integrity of your boiler. For instance, a boiler with a blocked drain line will produce faint gurgling sounds.  


 The above boiler maintenance checklist will help you improve the efficiency of your unit. A well-functioning system will last long and reduce utility bills. Maintaining a boiler requires a certain level of professionalism; therefore, you should consider hiring Aquatek plumbing and heating engineers.
