6 Steps on How to Maintain a Boiler Effectively


Written by Adrian

Having a boiler at home is essential, especially during the colder months. However, the boiler needs to be maintained at all times, which is why you need to take the necessary steps to ensure that it is in good working condition. Although there are some steps that you can perform by yourself, the overall process is often best taken care of by an expert. 

Before calling professional services, here are six steps you can take to maintain your boiler effectively: 

Have the Boiled Checked Regularly 

It is excellent if you have been performing daily boiler check-ups. Yet, it must still be checked by professionals regularly – at least once a year. These experts know the ins-and-outs of a boiler, and they can identify potential issues and address them immediately to prevent severe problems in the future. At the same time, keep in mind that it’s best to have your boiler checked before winter because you will want to handle the cold weather. 


Perform Regular Lubrication

If you want your boiler to work at its best at all times, you can do this by ensuring that it is properly lubricated. Be sure to lubricate specific areas, such as your fans and pumps, as these are the parts that perform repetitive motions. 


Make the Radiator Bleed

If you feel that your radiator feels colder at the bottom compared to the top, this could mean that air is trapped in the system. This is not a desirable situation because it will make your boiler work harder than it needs to, which can cause higher energy costs.

Radiator bleeding means that air will be released from the radiator. If you don’t have experience in performing this task, a professional will turn the heating to make your radiator bleed. Water will drip from the radiator, and once it does, it can be returned to its original position. Your technician will then check the pressure valve to ensure that the radiator is running with sufficient water. 


Always Monitor the Pressure

Keep in mind that your boiler must run with the right pressure for it to work at its best. To prevent any loss of pressure, you need to check it regularly. Your manual will contain information on the recommended pressure for it, and it will show you where you can find the gauge. Checking for pressure can easily be done, and you should do this at least once a month. 


Look Out for a Blue Flame

Boiler flames must be blue, so in case you notice a change in its colour, perhaps yellow or smoky, then it is an indicator that there’s something wrong with it. Don’t put this off because it will lead to carbon monoxide production that can damage your system. 


Clean the Boiler Inside Out

Your boiler should not be placed in a cramped room because it requires sufficient ventilation and air. Make sure to keep flammable materials away as well because it can cause a fire. Clean the outsides of it and make sure the room where it is located is clean. 

You should also clean the inside of your boiler, especially the air vent, flues, and hamper. In doing so, this will prevent a build-up of dirt that can compromise its performance. 



Keeping your boiler working at its best is important because it doesn’t come cheap. It’s an investment that can provide you comfort and convenience, which is why you should know how to take care of it properly. The six steps given can help ensure your boiler is working in good condition, especially during colder months.
