When Is It Time to Replace Your Boiler?

Boilers are pretty unique heating systems, especially when one considers how long they can last when properly maintained. There are boilers still in use today that are over a century old, with many more that are approaching 30 or 40 years of operation. Boilers last much longer, on average, than many other heating systems. Nothing lasts forever, though, and even boilers must be replaced at some point. Let’s take a look at the signs that it’s time to replace your boiler.

Heating Bills Go Up

Heating bills fluctuate from month to month, but there is a difference between a slight shift and a consistent rise in cost. When your heating bills start going up consistently, it’s a sign that your boiler is losing efficiency. This is often caused by excessive wear and tear from years of use. It’s a subtle sign, but a pretty reliable indicator of whether or not you should replace your boiler.

More Frequent Breakdowns

All heating systems are going to break down at some point. That’s just the way it goes. However, if your system is breaking down more frequently than in previous years it may be time to look at replacing it. As the wear and tear builds up on different parts, they all begin to fail in rapid succession towards the end of a boiler’s life. This is what causes the frequent breakdowns experienced by older boilers. You could try to keep replacing the parts as they fail, but the cost of doing so will very quickly eclipse the cost of simply replacing the entire boiler. If it seems like your boiler keeps breaking down every couple of months, you should seriously consider replacing it.


Age is another reliable indicator of when it’s time to replace a heating system. Though boilers occasionally buck this trend, the rule of thumb is that if your boiler is older than 15 years, it’s time to replace it. Now, if your boiler is older and doesn’t have any other issues, feel free to keep using it. Keep in mind, however, that a newer boiler would likely be much more efficient than keeping the old one.
