Discovering that something is wrong with one of your home’s core operating systems is never a fun experience. Unfortunately, it’s one that needs to be dealt with immediately, regardless of the upfront cost implications.

5 Signs Something Is Wrong With Your Boiler

If your boiler is on the fritz, leaving the issue unaddressed will cost more than scheduling a repair visit or replacement. Boiler issues can also pose health and safety concerns. Here are five signs that something is wrong with your boiler.

Leaking Fluid

A bit of condensation or “sweat” on the boiler is normal, as long as it isn’t impacting the pilot light. Condensation indicates a temperature difference between the room and the boiler. To be safe, however, it’s worth taking a look to ensure everything is working properly. A proper leak is when liquid is pooling or dripping around the base of the boiler. Fluid leaking is what leads many customers to call Paul The Plumber for boiler repair in Hampstead, New Hampshire. According to Paul, this liquid could be a number of things, depending on the type of boiler you have. If you notice a spatter pattern, it could be caused by leaking hydronic fluid. This fluid is also called transfer fluid and aids in transferring heat throughout the entire system. Your boiler could also leak water or oil; you can determine which by the odor and color. Regardless of what fluid is leaking, it’s a sign to call for an inspection and repair as soon as possible.

Strange Odors or Soot

Strange smells coming from your boiler are a sign that you should turn off the system, leave the property and call for assistance. If you detect a burning odor, it indicates that something is overheating in the system. While the danger might not be imminent, it’s a significant cause for concern. If you smell fuel or sulfur (similar to rotten eggs), there’s likely a gas leak putting your home and family at risk. If you’re on natural gas, call the gas company immediately before calling a repair service.



It’s important to note that not all toxins have a smell. Carbon monoxide is a tasteless, odorless poison that could be released into the home if the fuel isn’t being adequately burned. You should always keep a carbon monoxide detector near your furnace and near the bedrooms of your home. If you find soot around the burners, this indicates an issue with fuel burning and means carbon monoxide could be present.

Signs of Corrosion

A well-maintained residential boiler should last at least 15 years, though some types last longer. If you notice signs of corrosion, it’s time for an upgrade. Corrosion takes place when air leaks from valves or the exterior are exposed to excessive heat or moisture. At this point, the boiler will start to break down. If you schedule an annual furnace tune-up, you can have the technician look at the boiler and repair any issues that could shorten its lifespan.

Increased Repair Frequency

Having a great repair person on call is a must as a homeowner. However, you shouldn’t see this person often — no matter how much you like their business. If you find yourself requiring more and more service calls for repairs, it’s time to consider replacing your boiler. Luckily, you will have a great contact to guide you through the process.

Loud Banging Noises

While the inner workings of one’s home aren’t quiet, they shouldn’t be noticeably loud. When you live somewhere for an extended time, many of the home sounds fade into the background. If you start noticing loud banging noises coming from your boiler, it indicates a leak or pressure issue. Contact a specialist immediately. If you notice any of these issues, your boiler may need a repair or a replacement. Ensure you and your family are safe, then call a specialist — this isn’t a DIY job.
