Boilers are expected to last 10 to 15 years, maybe a few years more with proper care and maintenance. Knowing the signs of a boiler nearing the end of its service life can help you prepare for its eventual replacement. In this blog post, Burch Oil takes a look at four signs your boiler is approaching the end of its life span.
1. LOUD NOISES
While boilers are not exactly among the quietest heating systems, it generates a reasonable amount of noise that typically isn’t heard outside of the basement. However, there are noises that can indicate operational problems. Loud clanging and banging noises certainly merit the attention of a heating professional, and if the boiler makes the noise too often, you may be looking at replacing it soon.
2. LEAKS OR DISCOLORED WATER
Leaking or discolored water around the boiler are indicators that the system may no longer be able to effectively contain and heat the water. This could be due to a problem with seals or valves. Leaks are repairable, but just as often it can also indicate a sign that a boiler is nearing the end of its service life. Attempting to repair leaks is dangerous, especially if your radiators are heated by steam — stop using your boiler and call your heating contractor if this happens.
3. LOSS OF EFFICIENCY
Fuel-burning heating systems lose their efficiency over time. An old boiler will, therefore, deliver less heating the older it gets. If it takes noticeably longer for your home to warm up, or if you find yourself having to constantly adjust the thermostat in order to stay comfortable, it could be a sign that your boiler isn’t producing enough heat.
4. CORROSION
Most of today’s boiler systems are made to resist corrosion, however it can still happen when some components become exposed to air. If you find signs of rust or corrosion, it could be a sign that you need a new boiler, especially if the old rusted components aren’t made anymore.

My boiler started making some real loud kettle noises last night. I couldn't even sleep through it. Thank you for pointing out that calcium carbonate deposits can build up inside the boiler because of hard water deposits. Since I know nothing about boilers, I will call a boiler service company to come out and fix it so the noise is no longer there.
I've been having issues with my boiler. It makes sense that I would want to get a professional to repair my boiler for me. They would be able to ensure that it ends up fixing properly.
Thanks for explaining that limescale can build up due to excess hard water in the boiler. I'm hoping that I can call a boiler repair company to come and look at my boiler soon. I've noticed that there's limescale on it and I want to get it removed.
