The True Blue Mechanical Difference
HVAC Excellence With Personalized Care
Why Is Your Boiler Whistling?
Whistling sounds from your boiler, often called "kettling," can occur for various reasons, but it’s usually a sign of an underlying issue that needs attention. One common cause is a buildup of limescale or sludge inside the boiler's heat exchanger. Over time, this buildup can block the flow of water, which causes it to overheat and produce steam, resulting in that distinctive whistling sound. Areas like Newark with hard water are particularly prone to this problem, as our water supply tends to have higher levels of minerals contributing to limescale formation.
