Is It Worth Replacing an Old Boiler?

Replacing a boiler over 15 years old is usually worth it. Older non-condensing boilers run at 70–80% efficiency, while modern condensing models reach 90%+ — meaningfully lowering your gas bills. Add fewer breakdowns, available rebates, and improved reliability, and replacement often pays for itself over time.

The Efficiency Argument

An older boiler that operates at 75% efficiency wastes a quarter of the gas you pay for. A high-efficiency condensing boiler captures heat that older units send up the flue, reaching 90% or higher. Over a Greater Vancouver heating season, that efficiency gain translates into real savings on your FortisBC gas bill.

When Replacement Clearly Wins

Replacement makes the most sense when your boiler is over 15 years old, breaks down repeatedly, needs an expensive repair, or struggles to heat your home. If the repair cost approaches half the price of a new boiler, putting that money toward a new high-efficiency unit is the better long-term decision.
