If your home feels colder than it used to… if your gas bill keeps climbing… or if you're constantly resetting the boiler — your system might be trying to tell you something.
At Project Heating and Plumbing, we get this question all the time from homeowners across Okotoks, the Foothills, and Calgary:
“How do I know when it’s time to replace my boiler?”
Here’s a professional breakdown of the warning signs — and what to do about them.
Modern high-efficiency boilers are built to last around 15–20 years with proper maintenance. Beyond that, even well-installed units start to lose reliability and efficiency.
Red Flags:
Pro Tip: If your system is approaching the 20-year mark, it may still “work” — but it’s not working efficiently or safely.
Older boilers — especially non-condensing models — can lose a significant amount of energy to flue gases, standby losses, and short cycling.
Signs of Inefficiency:
Modern condensing boilers are up to 96% efficient, compared to ~60–70% for many legacy systems.
If you’ve memorized your boiler’s error codes, it might be time to move on.
Common issues in failing boilers:
Every repair adds up — and you’re still stuck with an outdated, underperforming system.
If certain rooms in your home are always cold, or your in-floor zones barely get warm, it could be a system design issue — or the boiler just isn’t keeping up anymore.
Watch for:
A proper upgrade includes system rebalancing — not just replacing the boiler, but correcting piping, zoning, and flow issues too.
Planning an addition, new garage, or full home reno? Your existing boiler may be undersized or incompatible with your future layout.
