If you have a boiler that is not acting right, you may be able to repair it instead of purchasing a new boiler. To help you decide, below are two problems boilers often have, as well as how to fix each problem. After reading, you should know if you can make the repairs on your own or if you need to hire an expert.
Not Heating Well
If you notice that the inside of the property is not heating well, then the boiler is the likely culprit. If the boiler has an automatic filling system, you should check the pressure relief valve to ensure that it is on the right setting. What this setting is will depend on the type of boiler system you have. You can refer to the owner's manual or ask a contractor to determine this.
If some areas are heated but others are not, there is likely too much air in the heating pipes. In order to repair this, you can open the bleed valve to let excess air escape. Make sure you close the valve when you start to see water squirting from it.
Pilot Light Not Lit
The pilot light should be lit at all times in order for your boiler to work properly. The flame should also always be blue. If the pilot light is not lit, you can try to light it yourself to see if it lights back up. If it does, then that should fix your problem. You will find instructions in the owner's manual on how to light the pilot light. You should understand that you should never light your pilot light if you are having any problems with your gas supply. Look at the gas stopcock to ensure it is on. If the gas stopcock is on, you need to contact the gas supplier.
If the pilot light keeps going out, then there is likely a problem with the thermocouple. If there is a problem with this, the thermocouple would need to be replaced. Fortunately, this part is not expensive. There could also be a deposit built up on the pilot light, and cleaning it could fix the problem.
Contact a boiler repair company if you continue having problems with your boiler. If the boiler is old, the contractor will likely suggest that you replace it. If not, the contractor will be able to repair the boiler for you so it will start running well.
