Why Are Weird Noises Coming Out of Your Boiler in Cape Charles, VA?

March 23, 2021

Manufacturers design boiler systems to operate smoothly and quietly. Strange noises from your boiler, including rattling, vibrating, and humming, require expert repair services. Here are four common reasons why you might be hearing unfamiliar boiler noises in your Cape Charles, VA, home.

Limescale Accumulation

Naturally occurring compounds and minerals in hard water can clog the piping system joined to the boiler. Additionally, limescale gradually builds up in the interior surface of the boiler, obstructing water flow.

Restricted flow causes hotspot formation and severe overheating in the heat exchanger. The trapped water undergoes rapid boiling, producing a kettling sound. Steam bubbles make loud banging noises as they rise in the boiler.

If your boiler produces such noises, it’s wise to call for immediate assistance from an HVAC expert. Professional descaling helps to clear excessive mineral accumulation. Scheduling routine maintenance is vital to identify and eliminate limescale buildup within the pipes and boiler.

Minimal Waterflow Rate

Undetected low water pressure overheats the boiler, resulting in hammering and rumbling sounds. A low flow rate could be due to several factors, including leaks, improper settings, and malfunctioning valves. Cold winter weather aggravates freezing pipes, hindering water flow even more.

Frequent inspection helps to identify small cracks and other faults within the boiler system. An HVAC specialist will also guide you on proper flow rate settings for your boiler.

Faulty Thermostat

Thermostat failure could be another reason why your boiler produces odd noises. Faulty thermostats are among the leading causes of overheating, which makes your boiler produce tapping noises.

It’s best to call an HVAC professional if you suspect thermostat failure. In case of severe damage, experts recommend thermostat replacement.

Air Locks in the Boiler

Air locks create a considerable pressure difference within your boiler. Usually, air penetrates to the boiler via cracks within the piping network. A valve malfunction could also contribute to air accumulation.

Make sure to contact an HVAC contractor if you hear recurrent banging and knocking coming from your boiler. The HVAC specialist will diagnose and fix air leaks to make your boiler operate properly.
