Boilers can provide hot water quickly, but they may experience technical issues from time to time. If your boiler is malfunctioning or nonfunctional, professional repair should be sought immediately.
Based on your technical skills, some issues could be repaired without professional intervention – potentially saving money on costly repair bills.
Working on boiler systems can be very risky, so if you need a professional for your plumbing concerns, feel free to contact the team at PlumbTech.
The pilot light isn’t working
The pilot light is key in keeping your boiler operating safely, and if it fails, your entire heating system could stop functioning as intended. If the pilot light goes out, your entire home heating system could stop functioning, with possible disastrous repercussions if this step fails to function as intended.
If your pilot light keeps flickering out, this could be caused by several different issues. One possibility could be with the thermocouple; this safety device detects when a flame ignites and will shut off if it doesn’t see that the pilot flame is burning.
If your thermocouple is misaligning or dirty, gently bend it back to correct it if worn-out thermocouples require replacement by professionals.
The thermostat isn’t working
An ineffective boiler can often be fixed by setting the thermostat to “heat.” Additionally, make sure the temperature setting exceeds room temperature.
Low-pressure boilers present a serious safety hazard. While it may be possible to repressurize the system using instructions in its owner’s manual, professional training and knowledge should always be sought in order to do this properly.
Another common boiler issue is producing lukewarm water, often due to a malfunctioning diverter valve or other causes. Consult the boiler manual for troubleshooting steps; if necessary, consider replacing it and/or checking fuse boxes and circuit breakers for any potential tripping or blowing outs.
The pilot light keeps going out
If the pilot light on your boiler continually going out, a problem with its thermocouple could be to blame. This safety feature shuts off the gas valve when the pilot light fails; to remedy the situation, use a dry cloth or sandpaper to clean off and/or replace the thermocouple as soon as possible.
Air may have made its way into your gas line, preventing the pilot light from lighting properly. To alleviate this situation, contact a professional immediately to expel it and clear your system of any obstructions to lighting.
Pilot lights may go out due to problems with either the thermostat or fuse box, requiring you to change or reset them as appropriate. Verify that they’re set correctly (heat mode above room temperature, for instance). A diverter valve that’s no longer functioning could also stop hot water flowing to taps and showers, rendering the pilot light useless.
The thermostat keeps turning off
If your boiler keeps shutting off despite you double-checking that all switches and wiring are undamaged and no power outages have reset its temperature, the thermostat could be to blame. It could have been set too low or reset by an outage; to fix this issue, you’ll need to adjust it by several degrees and increase the heating output again.
Your boiler may keep turning off due to leaky pressure relief valve. To check this isn’t happening, release water manually from the valve and look for sediment build-up around its openings.
If your boiler keeps turning off or you experience any of the other symptoms listed here, it may be time to contact a Gas Safe registered engineer for professional assistance. Working on boiler systems can be extremely hazardous; only those trained can undertake such work safely.
The pilot light keeps turning on
A pilot light on a gas boiler provides constant warmth to its system. When this flame goes out, the system won’t function correctly due to either low pressure or restricted water flow through your pipes due to deposits or corrosion that reduce water circulation.
Your pilot might also keep going out due to issues with your thermocouple. If its probe gets knocked out of position, it won’t detect flame, and your gas valve will shut off automatically.
To rectify this situation, gently attempt to bend back the probe back into place or clean your thermocouple if it becomes dirty so that it better detects flame – both methods should help restore proper functioning – professional boiler heating repair service providers may be necessary in some instances.
