Is Your Boiler In Trouble?

Posted on

Boiler heating systems can be found in many residential properties across the country. A boiler utilizes steam to help generate the heated air you need to keep your home comfortable. If your property is equipped with a boiler, you need to be aware of the warning signs that the boiler is in trouble.

A boiler that isn't maintained properly can become a serious safety hazard, so be on the lookout for the following signs of trouble.


Have you ever heard the whistle of a teapot when it comes to a boil? If so, then you should be able to recognize a boiler that is kettling. Kettling is a phenomenon that occurs when the mineral buildup inside your boiler reaches dangerous levels.

Mineral buildup has the potential to restrict your boiler's ability to maintain the proper water temperature. The water can become overheated, which puts strain on the pipe fittings and connections. Contact a repair technician as soon as you hear any loud banging, whistling, or whining sounds coming from your boiler.

Pooling Water

A residential boiler system is designed as a contained system. This means that you shouldn't see any visible evidence of moisture when the boiler is working properly. Pooling water near your boiler is cause for serious concern.

The leak might be coming from the boiler tank. Most boiler tanks are made from metal, which can corrode over time. Severe corrosion eats through the walls of the tank and allows water to leak out.

Other leaks could be caused by a faulty pressure relief valve. Regardless of the source of the pooling water, a repair technician should be called in immediately to address the leak. Immediate repair is the only way to preserve the safety of a leaking boiler.

Faulty Pilot Ignition

Older boilers were equipped with an ignition system that required the manual lighting of a pilot light. Modern boilers are equipped with electronic ignition systems that can work independently. These electric ignitions have increased safety and convenience, but they have the potential to create performance problems when they short out.

The easiest way to recognize a faulty pilot ignition is to pay attention to the warmth of the air being circulated through your home. A sudden drop in air temperature can be caused by a faulty pilot ignition.

Your HVAC repair professional will need to identify the source of the problem and make any necessary boiler repairs before your boiler can effectively heat your home again.
