Gas boilers are reliable, but like any mechanical system, they can develop issues. As a heating engineer servicing Surrey and South West London, I’ve compiled a list of common gas boiler problems and how to troubleshoot them. Remember, while some issues can be resolved with simple checks, others will require professional assistance.
No Heat or Hot Water
This could be caused by several issues, such as a broken diaphragm, airlocks, or issues with the thermostat. First, check if the thermostat is set correctly and working. If it seems to be a mechanical issue, it’s best to call a professional.
Leaking and Dripping
Leaks can come from various components. The location of the drip can often indicate the problem, whether it’s a pressure valve issue or a pump seal failure. If you notice leaking, it’s advisable to contact a professional as soon as possible to prevent further damage.
Strange Noises
Banging, whistling, or gurgling noises can be alarming. These sounds can indicate air in the system, low water pressure, or limescale buildup in the heat exchanger. While you can check the pressure and bleed radiators yourself, dealing with limescale or airlocks might require a professional.
Pilot Light Goes Out
If your boiler’s pilot light keeps going out, check for drafts or issues with the gas supply. It could also be a worn-out thermocouple that’s cutting off the gas supply. Replacing a thermocouple is a job for a professional.
Thermostat Issues
If the thermostat is losing accuracy or turning the heating on/off at inappropriate times, it may need to be recalibrated or replaced. Consider upgrading to a smart thermostat for better efficiency.
Pressure Loss
If your boiler frequently loses pressure, it could be due to a water leak in the system or a failing pressure relief valve. Check for visible leaks and repressurize the system if necessary.
