Boiler Problems to Watch Out for This Season

Monday, December 5th, 2016

Utah is one state where you will see a lot of boiler systems—and for good reason. They provide reliable heat to homeowners throughout the state during what can be a few months of bone-chilling weather. One of the biggest benefits of boilers, too, is that they generally have fewer repair needs than other heating systems such as furnaces and heat pumps.

The reason for this is because boilers have a much smaller number of mechanical parts than other heating systems, meaning they have fewer components that wear down. They don’t need these components to circulate hot water throughout your home. However, no boiler is immune to problems, and you might still need to call for repair service at some point during the service life of your boiler.

Common Boiler Repairs

Friday, January 16th, 2015

Boilers are just as susceptible to breakdowns and repair needs as any other heating system. Since boilers are a bit more uncommon than things like furnaces, however, their potential problems tend to be less well-known. Let’s take a look at some of the more common boiler repairs that homeowners run into, and what should be done about them.


Kettling is when your boiler makes a deep rumbling sound, like a large kettle boiling. This is caused by long-term exposure to hard water, which is common in many areas of the United States. Hard water is characterized by a high mineral content, which can have a negative effect on the water pipes in a home. As hard water flows through the boiler’s heat exchanger, it deposits small amounts of minerals on the walls of the pipe. Over many years, those deposits build up until they restrict or completely block the flow of water through the heat exchanger. This causes water to become trapped in the heat exchanger, where it boils.

Believe it or not, most boilers are not actually designed to boil water. When water boils inside the heat exchanger, it evaporates into steam which puts tremendous pressure on the pipe. This is what causes that rumbling sound when a boiler kettles. If left untreated, this can actually cause the heat exchanger to rupture, though there are safety measures in place to shut the boiler down before that happens. Regardless, you should call a professional if you notice your boiler kettling.

Pilot Light Failing

Pilot lights have earned a pretty bad reputation for going out at the drop of a hat. Despite their propensity for blowing out easily, however, there is a difference between blowing out often and refusing to stay lit. If your pilot light is not staying lit for longer than a very short time, it’s probably due to a bad thermocouple. The thermocouple is a part that detects the heat from the pilot light and opens the gas valve to keep it going. When the pilot light blows out, the thermocouple is supposed to close the gas valve as a safety measure. A bad thermocouple is one that closes the gas valve prematurely, smothering the pilot light. The most common fix for this is simply to replace the thermocouple.
