A boiler is an important heating system in many homes. Boilers and radiant heat systems can malfunction from time to time. Some signs that your boiler is experiencing problems may include a lack of heat, water leaking, or strange noises. If you own a boiler, keep an eye out for the following problems so that you can catch them before they worsen or cause further damage.
If your boiler is having trouble producing hot water, there may be an issue with boiler pressure or a thermostat. A lack of hot water could mean a broken diaphragm, airlock, or valve. If you notice this issue, call a professional to come take a look—you’ll likely need a part replaced.
If there is an issue with your boiler, you may be hearing a rumbling noise similar to the sound a kettle makes when it is boiling. This could mean that there is limescale or sludge build-up on the boiler’s heat exchanger, causing a restriction of water flow. This will cause your boiler to work harder—potentially shortening its life and increasing your energy bills.
The small blue flame in a boiler is known as the pilot light. If this light is continuously going out, it could be due to a broken thermocouple which is stopping the gas supply. If your pilot light has gone out, before trying to reignite it, be sure there aren’t any issues going on with the gas supply—this could be very dangerous. It could also be a problem with your gas supplier.
There are many common issues with boilers that could lead to water leaking. Most commonly, a leak or drip is caused by a broken internal component. This could be the pressure valve, a pump seal, or another part. If the boiler’s pressure is too high, it could cause a problem with the pressure valve. However, if the problem is the pump seal, it is likely just worn out and needs to be replaced.
The leaking water may not be directly from your boiler—it could also come from corroded or ill-fitting pipes.
5. Low Pressure
Check the pressure of your boiler by looking at the built-in pressure gauge. If it is below one, you have low boiler pressure. This could lead to your heating system not functioning properly. Low boiler pressure can be a result of a faulty pressure relief valve, a water leak in the system, or another issue. Look for any visible leaks that could potentially be the problem.
Other common issues include the thermostat not working properly, an increase in utility bills, carbon monoxide detector going off, or an uneven distribution of heat throughout your house.
