Boiler Inspections

When to Maintain a Gas Boiler?

Before the start of winter, checking the boiler helps prevent a breakdown in the middle of December and the need to purchase new parts for your system.
Among the necessary checks are all the safety-related boiler components (safety valve, heating safety valve, NTC probe, temperature sensor, thermistor, ...).
The heat exchanger, also called the heating exchanger, must be cleaned to ensure proper operation and heat distribution.
The expansion tank absorbs excess pressure and needs to be properly inflated.
You should also watch for gas leaks, which could pose a real danger to the occupants of the house.

Tools

To carry out this operation, you'll need:

• A set of wrenches
• A pair of gloves
• Safety goggles
• A protective mask
• Rags
• Sandpaper
• A brush
• Boiler cleaner
• An vacuum
• Gas leak detector
• Neutral gas for the expansion tank

How to Maintain a Gas Boiler? (text)

SAM:
For the proper functioning of your boiler, it’s important to have a heating technician come once a year. During their visit, they should check every part that could cause performance drops.
It’s essential to start with the cleaning.

THIERRY:
Only then does your technician take care of the checks and control of the elements.

SAM:

In the cleaning part, there’s of course the heat exchanger, which must be freed from any impurities.

THIERRY:
Absolutely. You then need to clean the area where the gas burns, namely the burner and the electrodes. Then the smoke extraction part, including the extractor if your boiler has one.

SAM:
Now let’s move on to the checks. The pump must operate properly, just like the other internal components of the boiler.

THIERRY:
Speaking of internal components, the boiler has many safety elements (low water safety, overheating safety, etc.) that may need to be checked.

SAM:
The technician should ensure that the heating expansion tank is well-inflated, that the temperature is appropriate, and that the water flow in the boiler is correct. Additionally, the gas flow should also be checked.

THIERRY:
And for everyone’s safety, there’s something else to check.

SAM:
Yes, tightness! Both for water and for gas! A leak would be a disaster for you and your surroundings.

THIERRY:
If gas escapes, you’ll notice it quickly!
We’ve covered the technician’s visit. All that’s left is to perform a functioning test for the heating and the hot water by relighting the boiler.
