More Boiler Problems
“Kettling” is a term that describes when hot water cannot escape your boiler. This happens when there is a blockage throughout the boiler and radiator system, which will keep the heated water from circulating as it should. This is a serious issue, since it can make your boiler dangerous, and the boiler may continue to run, since the thermostat will still indicate that your home or building is too cool. If you notice that your boiler is kettling (which will be indicated by a whistling noise from the boiler), then you should turn off your boiler at the thermostat, and contact a boiler technician to take a look.
Your boiler should be relatively quiet as it operates. While you will hear a whooshing sound while your boiler is on (thanks to the flame of your boiler), and you may hear small crackling and popping noises throughout your radiators as they heat up, there are other sounds that should be concerning. Be mindful that a whistling boiler is a sign of kettling — as we just mentioned. Also, be wary of bubbling, clunks, and other odd noises which may be a sign that a component is loose in your boiler, or you have a blockage somewhere throughout the system. You can describe the boiler noises that you’re hearing to us, and we’ll assess the issue at hand.
Your thermostat is responsible for measuring the temperature of your home in order to turn on your boiler at a set temperature. If you have a thermostat that is uncalibrated, or simply not working altogether, then you may have poor heat in your home, or your boiler may not turn on at all. If you suspect that your thermostat is the source of an issue, we can take a look. We may be able to recalibrate your thermostat, we may recommend moving the unit, or we may have to replace the unit with a more current model.
