Boilers are dependable heating systems, and because they have fewer moving parts than furnaces or heat pumps, they are less prone to wear and tear and last longer in general. But there are times when boiler repairs are necessary to prevent more significant problems further down the line. These are some indications that you need to schedule boiler repairs.
Rumbling and rattling sounds
Your boiler won’t explode, but when you hear a rumbling and rattling sound from the boiler, it’s generally a clear sign that something is wrong.
One source of the noise may be that the circulating pump is malfunctioning and shuddering inside its casing. As one of the few mechanical parts of the boiler, the pump needs to be monitored closely. If the sound is coming from inside the boiler tank, there is likely a build-up on the bottom of the tank, causing overheating and reducing your boiler’s efficiency. A technician will be able to diagnose the problem and take care of the boiler repairs.
The boiler is designed as a closed-loop system, and water should never escape from it. If you notice water puddling around the boiler tank, it is a clear indication that it’s necessary to book for boiler repairs. Call an expert to seal up the leaks, replace lost water, and ensure your boiler continue to work safely and effectively.
Delays in heating
If you’ve had your boiler for a few years, you have a good idea of how long it takes on average for a room to start to heat up once the boiler’s turned on. If it’s taking much longer than before, there may be a circulation issue with the boiler. Depending on the age of your boiler, you may need to replace it. If your boiler is newer than 15 years, a technician can diagnose the problem and repair it.
Unusual smells near the boiler are always a bad sign. If it smells like burning plastic or metal, there is likely some trouble with the circuits. If it smells like rotten eggs, it could possibly be a gas leak – a serious problem. Shut off the gas to the boiler, call the experts, and leave the house.
Something as simple as an increase in your energy bill during times the boiler should be hard at work could indicate that boiler repairs may be necessary.
