My Commercial Boiler Makes Banging Sounds

What do you know about kettling? Is it:

A. The process of sweetening popcorn

B. A new sport played on the ice with brooms and tea kettles

C. A sign your boiler needs attention

If you chose C, you know boilers.

Kettling is the reason you hear a banging noise coming from your commercial boiler. The kettling process starts with a very hot heat exchanger. Water that touches the overheated component boils, turns to steam, and expands, creating the banging noise.

Imagine listening to boiler sounds while trying to conduct business in Warman or Martensville. Why interrupt your work with ongoing and annoying noises?

Unusual boiler sounds may cause customers to feel uncomfortable. Employees may be unable to focus on their work.

AquaTemp can stop the kettling and banging. Our commercial services team offers practical solutions to keep your heating, ventilation, and air conditioning (HVAC) system in top condition. We want to help you get the best value out of your equipment.

Don’t ignore the banging sound your boiler makes. It won’t go away on its own. If your boiler is kettling, call us for an inspection, tune-up, and repair.

What Causes an Overheated Heat Exchanger?

A corrosion that results from calcium carbonate deposits in water called limescale may be at the root of your commercial boiler’s kettling. 

Limescale can build up on the heat exchanger and make it harder for the component to heat the water around it. As a result, the boiler’s burners work harder, and the heat exchanger ends up becoming too hot.

Boilers are not designed to boil water. The system heats water to below the boiling point before sending it through pipes to heat your Saskatchewan building.

A malfunctioning boiler thermostat also could cause the burners to remain on longer than necessary, causing the heat exchanger to overheat.

Low water pressure, a water temperature setting that is too high, and a leaky system also may contribute boiler noise. 

Our AquaTemp professionals can pinpoint the cause and recommend the best course of action for your needs. 

Avoid Kettling Through Maintenance

Maintaining your commercial heating system is key to extending its service life and improving its performance. Regular preventative maintenance should at least include an inspection of the pressure tank, tests of the pressure-relief valve and the high-limit control, and thorough heat exchanger cleaning.

Our trained professionals also inspect for leaks, lubricate moving parts, replace filters, and check gas connections. We ensure your HVAC system is reliable and running at peak efficiency when heating your Martensville or Warman facility. 

If your boiler is more than 15 years old, you may want to consider replacing it with a high-efficiency model that supports smart technology.

Increasing energy bills, frequent repairs, and lack of replacement parts are indicators your aging boiler is nearing the end of its useful service life.
