Cold weather can really put your boiler to the test. While boilers typically need fewer repairs than furnaces or heat pumps, they are still a complex piece of machinery that can hit a snag every once in a while.
Since boiler problems are so few and far between, it’s important that you’re able to spot them and get them fixed right away by a plumbing professional. Read on to learn more about the most common boiler repairs and the issues that cause them.
This is one of the more challenging plumbing issues to diagnose. If a boiler is not producing heat, it may be a problem with the system diaphragm, a faulty motorized valve, or low pressure. It could even be something as simple as a broken thermostat.
The only way to know for sure is to call in an expert for a thorough inspection. Keep in mind that, although boilers can last a long time, all machinery breaks down eventually. A professional will be able to tell you if your boiler can be repaired or if your system needs replacing.
Kettling is just like it sounds – your boiler may make a strange squealing or rumbling noises like a tea kettle heating up. This happens as a result of deposit build-up in your unit’s heat exchanger. This debris build-up is part of normal water usage, but it can clog the flow and lead to overheating.
The most common remedy for kettling is to remove the heat exchanger and give it a good scrubbing. If the build-up is limescale, it may need more deep cleaning or even a full replacement.
Leaking or Dripping
Boilers that leak or drip is another common issue that we often encounter. Leaking water is typically an issue caused by an internal component, like a pressure valve or pump seal. Sometimes, it can even be something as simple as loose-fitting!
A leak coming from your pressure valve can mean that the unit’s pressure is too high. If it’s coming from the pump seal, it is most likely worn out and will need to be replaced.
Pilot Light Issues
While newer boilers use electronic ignition, others still rely on a pilot light. Your boiler’s pilot light is a flame located underneath the system that keeps it up and running. When the pilot light continuously shuts off, it typically means the thermocouple is faulty.
There are many different reasons your pilot light may be having trouble, including a blocked burner, faulty gas valve, or even trapped air. A plumbing professional will be able to quickly diagnose the problem and make the necessary repairs.
