What are 4 Common Boiler Repairs?

A boiler is a complex mechanical device. Despite this, it is a model that requires little heating system maintenance. One of the best things about a boiler is how long it lasts and how little maintenance it requires. That’s why it’s understandable if you’re astonished when your boiler breaks down, but it’s going to happen at some point.

Consider some of the issues you can face if you possess a boiler rather than a forced-air heating system like a furnace. (Apart from their ignition mechanisms, these are two entirely different systems.) It’s vital to know what to expect, but it’s even better to understand that performing regular maintenance work on your home is a good idea.  


Kettling is a typical issue with hot water boilers. If you’re unfamiliar with the phrase, you may be familiar with the sound it makes: a loud pounding or rumbling from the heating unit. If this applies to your heater, but you haven’t had a specialist look at it yet, now is the time. Unfortunately, this issue has the potential to grow into a far more significant problem than it is today.  

The problem is due to an excess of minerals in the water supply. Hard water is normal in our location. However, the mineral deposits in the tank modify the pressure levels with time. As a result, a kettling boiler is more likely to leak or have unsafe amounts of carbon monoxide, putting your household at risk. 

Leaking and Dripping

When a boiler begins to leak, another typical boiler repair issue often comes to us as an emergency call. If the leak is coming directly from the boiler tank, you’re dealing with a significant problem. The boiler has most likely rusted through and will need replacement. A pressure relief valve or a pump, on the other hand, might cause a leak, which we can fix. We’ve even found that sometimes a suspected leak was a condensation! 

Pilot Troubles

The pilot light isn’t as bright as it formerly was. Previously, you had to start the pilot light and leave it running all day and night to ensure that heat was always available. Some boilers still use this technology today, while others rely on electrical ignition to heat water only when required. You’ll need heating professionals to assess pilot and ignition system difficulties if you can’t ignite a pilot light on your own. 

No Heat

When we get a call about a boiler that isn’t working, we never know what we’ll find. While the issue may be related to ignition, there are other possibilities to explore. For example, it’s possible that a safety switch prevents the boiler from remaining lit, that a pump is malfunctioning, or that you have a defective thermostat.  

There’s no need to try to figure out what’s wrong on your own. For repairs, contact a trained specialist for boiler repair service. To minimize costly repairs, have your local experts do maintenance once a year.
