What Are These Noises from My Boiler?

Boilers are known for their quiet operation. Unlike forced-air heating systems, which may have loud fans and motors running at all times, boilers have far fewer moving parts, and these are usually out of the way of your living space. You might not notice that your boiler is in trouble until you move closer to the unit itself, but when you hear loud rumbling, rattling, or other noises, it can seem quite alarming.

When you notice odd sounds from your boiler unit or anywhere in your home heating system when you run the boiler, call Boehmer Heating & Cooling.

Common Noises and What They Mean

If you hear a rumbling or rattling noise from the tank of your boiler, it could mean trouble. Most likely, the source of the rumbling is sediment in the tank. Sediment builds up as hard water moves into the pipes with your water supply. Hard water is water that has a high concentration of minerals like calcium and magnesium. These can leave deposits in the tank, which can then rattle around and cause a bit of noise.

More important than the noise, however, is the effect that these minerals have on the performance of your boiler. When sediment builds up too much, the volume in the tank decreases, which means that pressure increases. Long ago, a boiler in this position could be at risk of exploding, but this is not a concern today. Safety features on the boiler should shut down the unit if the pressure becomes too high or water may leak out from a relief valve. Either way, this is not an ideal situation to be in, and you should have a technician look at the system as soon as you can.

Noises from your boiler, from the baseboard heater or radiator, or from the pipes underneath your floorboard can all indicate trouble. Often, noises from locations besides the boiler tank itself could indicate circulator pump trouble. This can lead to uneven heating or none at all.

Call us today at Boehmer Heating & Cooling. We can drain sediment from your boiler or find a suitable solution with our boiler repair service in Bethel Park. In some cases, a replacement is necessary, but we can help you to find the best system for your replacement needs quickly.
