Some Specific Problems That Can Affect a Boiler

As you start to think about heating your home this coming winter, you’ll want to consider your heating system and the work it may require. If you use a boiler to warm your home, then you won’t have to worry often about scheduling repairs for it: boilers need fewer repairs than systems with more mechanical parts, such as furnaces. As long as you stay current with annual maintenance for your boiler (and right now is a great time to schedule maintenance), you’ll rarely need to call us for boiler repair in Colorado Springs, CO.

Of course, no boiler is indestructible. In this post, we want to look at several specific boiler malfunctions you may encounter during the winters. As soon as you recognize that there’s something wrong with your boiler, call our technicians. We offer 24-hour emergency service to ensure you get the repairs you need and have your heating restored.


Any system that uses water is in danger of developing leaks—and leaks are always a problem. Not only do leaks cause water damage, they often indicate something else wrong within the boiler. A boiler circulates water in a closed loop, so loss of water affects the boiler’s capacity to deliver heat to the house. A leak can warn that the boiler is starting to corrode (often at connection points) or is overheating. We’ll locate all the leaks and find out what other work the boiler requires.


This noise is a popping, whistling, and banging sound named after the noises heard from an overheated kettle. There are several possible causes for kettling. One of the most common is a layer of sediment in the boiler tank that traps water over where the heat exchanger is heating the water. The water under the layer will boil up through the sediment layer and create the kettling sound. Kettling can also come from limescale build-up or a broken pump.

Ignition failure

You might discover that your boiler isn’t providing heat because the gas burners aren’t igniting. For older boilers, this may be due to the pilot light going out. Most newer boilers don’t use a pilot light, but instead ignite the gas from the burners using an electronic ignition system. An ignition system can fail and need to be replaced, and you’ll want to have professionals handle the task. The professionals can also check on gas flow and the condition of the burners to see if there’s another reason for the burners’ failing to ignite.

Frozen condensate pipe

This often happens in our cold winters in Colorado. The condensate pipe removes the condensate moisture from the heat exchanger to the outside. Freezing temperatures can cause the moisture to freeze the pipe and block the exhaust, eventually causing the boiler to shut down. You can rely on our team to handle unthawing the pipe as well as find methods to help prevent this in the future.
