Signs That You Have a Boiler Problem

Boilers are known for being remarkably hardy systems. Compared to furnaces or heat pumps, they last quite a long time and with a smaller number of problems. This is largely because they have fewer moving parts, which means there are not as many ways for them to break down. They are not invincible devices, however. Your boiler can still develop some nasty problems, several of which can cause a complete system breakdowns. It’s important that you be able to identify when your boiler is malfunctioning, so that you can call for repairs as soon as possible. With that in mind, let’s take a look at some signs that your boiler has a problem.


A deep rumbling noise coming from your boiler is a sign that it is kettling. Kettling occurs when the flow of water through the heat exchanger is obstructed, causing steam to build up in the pipe and threatening to rupture it. If that happens, it will cause widespread water damage and you’re going to need to replace the heat exchanger. Turn off the boiler and call for repairs as soon as you can.

Uneven Heating

If part of your house doesn’t seem to be getting any heat while the boiler is currently running, it could mean a number of different things. The boiler might have a problem with the circulation pump, or there may be a blockage in the pipe network that is preventing hot water from reaching that part of the house. You may even have a leak in the pipe somewhere, which will need to be dealt with immediately. You will need to have a professional examine the system to know for certain.
