3 Boiler Noises in Alexandria, VA and What They Mean

Boilers are the most reliable and durable heating systems in the market. However, your boiler system in Alexandra, VA, can still have issues; they’re not immune to normal wear and tear. Read on to learn some common boiler noises and what they mean.

1. Rumbling Noises

A rumbling noise, also referred to as a kettling sound, can happen when limescale has built up inside of the boiler’s heat exchanger. This is usually caused when hard water runs through the boiler for an extended period of time, leaving behind mineral deposits.

Water leaving behind mineral deposits is normal. However, over time, those deposits can build up to the point that they block water from flowing through the heat exchanger.

When this happens, the water in the pipe evaporates, turning into steam and exerting pressure on the heat exchanger. That, in turn, causes the kettling sound. You’ll need to contact a professional to fix the issue.

2. Gurgling Noises

You might hear your pipes gurgling; since the pipes throughout your home connect to your boiler at some point, this sound might actually originate within the boiler itself rather than the pipes. Oftentimes, you’ll notice that your water is heating unevenly or not heating at all, along with the gurgling sound.

Gurgling sounds are usually caused by air bubbles in your pipes, which hinder your water flow. The best way to manage this problem is to call a qualified HVAC technician for maintenance so they can draw air from the system.

3. Humming Sounds

Humming sounds coming from your boiler could stem from a variety of issues. If you have an electric boiler, for example, its heating element may be loose.

Excessively high water pressure can also cause humming sounds. The pressurized water can cause your pipes to vibrate; it may also lead to a humming sound from the valves on your faucets.
