Is Your Boiler Making Weird Noises? Horsham. January 07, 2025 Is Your Boiler Making Weird Noises? Here's What They Could Mean.Has your boiler started making some seriously strange noises? Maybe it's a banging, a whistling, or even a gurgling sound. Noises like that can be unsettling, plus they make you wonder if something's wrong. Let's break down some of the most common boiler noises and what they might mean. Banging or Knocking: This is probably the most common one, and usually, it's a sign that your boiler's expansion vessel needs some attention. That vessel's job is to deal with pressure changes, so if it's not doing its job, you'll hear that banging noise.Whistling: Whistling usually points to low water pressure, which can cause all sorts of problems. You might need to refill your heating system.Gurgling: Gurgling noises happen when there's trapped air in your system. It's kinda like having a burping tummy, but way less fun. You can try bleeding your radiators to get rid of that air. Here's the thing, though: If you're hearing noises that worry you, don't ignore them. Give Andrew a call.
