Boilers can be remarkably sturdy machines. Some well-maintained iron boilers have lasted over a century, and still see use in homes today. Despite their hardy natures, however, even boilers have a limit to their longevity. When that limit is reached, it pays to recognize the signs so that you can replace your boiler before it fails.
Rising Maintenance and Repair Costs
The easiest way to tell if your boiler is reaching the end of its life is by monitoring the cost of maintenance and repairs. If the cost of simple maintenance is significantly higher this year than it was the year before that, and the year before that, your boiler may be reaching the end of its life. The simple fact of the matter is that wear and tear is inevitable. No matter how well you maintain your boiler system, the years and decades of use will eventually cause parts to fail. This will happen more and more often, causing an increase in repair costs. Which brings us to our next point.
Frequency of Repairs
If you find yourself calling for boiler repair more and more frequently, especially within a relatively short period of time, you may need to replace your boiler. As mentioned above, wear and tear will become more and more pronounced on a system as it gets older. Since different parts tend to experience different levels of stress during normal operation, this can cause a waterfall effect. You may have just finished getting one part replaced when another one fails, and you have to start the whole process over again. This isn’t just annoying, it’s expensive. If it starts to seem like your boiler is in a constant state of disrepair, it’s time to replace it.
If you begin to experience cold spots or other signs of uneven heating, it’s a good sign of problems with your boiler. One or two occurrences isn’t necessarily a sign of a deteriorating boiler. When the noticeable decrease in heating becomes constant, however, that is a reliable indication of a failing boiler.
