4 Common Boiler Repairs

Modern high-efficiency boilers are a model of reliability and durability. That’s the good news. The bad news is that they are so reliable and durable people tend to forget about boiler maintenance. They are still a complicated piece of equipment and can require repairs if they don’t receive seasonal maintenance from the pros at Builder’s Heating & Air Conditioning.

Kettling

This is a major problem for hot water boilers at the heart of your radiant heating system. You may not recognize the word, but you might recognize the sound it makes. Kettling is when the boiler makes a loud banging or rumbling sound. Don’t procrastinate on this one. If you don’t have a technician investigate, it can become a much larger problem.

Many times, the kettling is caused by mineral deposits in the boiler. Over time the deposits change the pressure levels in the tank. A boiler that is kettling is more likely to spring a leak. In extreme cases, the increased pressure could pose a danger in your Denver, CO home.

Drips & leaks

This is another common boiler repair. We often get emergency calls from homeowners when they see evidence of a boiler that is leaking. If the leak is coming directly from the boiler tank in the heating system, then replacement is generally the only option because the boiler has started to corrode. Sometimes the leak can come from a relief valve or pump which can generally be repaired.

Pilot light problems

Technically, it may be more accurate to say ignition problems. Many modern boilers have electronic igniters, but there are still a lot of heating systems with the older gas pilot lights. Either way, your boiler isn’t going to work if there’s a problem with the ignition system. In most cases, the only choice when an electronic igniter stops working is to replace it. Please be cautious if you are having trouble lighting the old-fashioned pilot light. We don’t want to see natural gas or propane leaking into your home. If you are uncomfortable with the process of lighting the pilot light, it might be better to call in a technician to take care of it.

A boiler that doesn’t boil

When there is no heat coming from a boiler there are a number of factors to consider. First, we will make sure the ignition system we just talked about is working properly. Other possible causes include:

  • A malfunctioning safety switch
  • A broken pump
  • Thermostat not working properly
