Quick answer
In 2026, replacing a natural gas boiler in Vancouver is a ballpark of $7,500 to $15,000+. That is a ballpark, not a quote, and the CANRO office confirms the figure after a short assessment. The main things that move it are the type of boiler, venting changes, the gas line, the condition of the existing pipework and radiators, and access in older Vancouver homes.

A full boiler replacement in Vancouver is a ballpark of $7,500 to $15,000+. A new boiler install, where there is no existing unit to remove, is a ballpark of $6,500 to $14,000+, and a combi boiler that heats the house and supplies hot water is a ballpark of $9,000 to $16,000. All of these are ballparks, not quotes.
What moves the number is rarely the boiler alone. Venting, the condition of the existing system, access and the amount of tidy-up pipework often decide whether a job lands near the bottom or the top. The CANRO office confirms the figure after a short assessment, and you receive a written quote before work begins.
CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. A gas permit is a typical ballpark of $75 to $200 on its own and is part of the overall figure.
Vancouver's older character houses, post-war bungalows and Vancouver Specials are where most hydronic replacements happen. The old boiler is often an atmospheric unit with a masonry chimney, and a modern condensing boiler cannot share that flue. Venting through an outside wall brings its own considerations: clearances to windows, doors and property lines, and the noise or plume of the termination near a neighbour's wall in a narrow lot.
Mechanical rooms in basements and crawlspaces can be tight, and getting a heavy old cast-iron boiler out is real labour. In some older houses the insulation on old pipes is of a type that needs to be identified before it is disturbed, which can add steps. Suites and laneway units add zones, and an extra loop means extra controls and pipework.
| Factor | Effect on price | Why it matters in Vancouver |
|---|---|---|
| Boiler type (standard or combi) | Combi sits at the higher ballpark | Combi replaces a separate hot-water tank |
| Venting change | Raises the price | Old chimneys often unsuitable for a condensing unit |
| Gas line capacity | May add work | Older homes sometimes need a larger or re-routed gas line |
| Condition of pipework and radiators | Can raise or lower it | Cast-iron systems are durable but may need cleaning |
| Access to the mechanical room | Adds labour in tight spaces | Basement stairs and crawlspaces are common |
| Number of zones | More zones, more controls | Suites and add-on loops |
| Permits and inspection | Included in the quote | Gas permit ballpark is $75 to $200 |
Most boiler repairs are modest. A repair is typically a ballpark of $250 to $1,800, with most between $400 and $900. A control board is a ballpark of $570 to $1,040, a circulator pump $300 to $1,100, and a heat exchanger $840 to $2,180. The heat exchanger is the one that often tips a decision toward replacement, since it is the heart of the boiler.
Replacement also deserves attention when repairs are becoming frequent, parts are hard to find, the boiler is an old atmospheric model with a failing flue, or the system struggles to heat the house. Cost per year is a better yardstick than the number on any one invoice, and a technician should walk you through the reasoning.
If your boiler is failing and the weather is turning, October is better than January for scheduling. Summer is when replacement work is easiest to plan, but a failing boiler cannot always wait. Rebate programs through FortisBC, CleanBC and the federal government change, so confirm current eligibility before you sign; the Greener Homes Grant is closed, and any loan or provincial program should be checked directly.
Safety note
If you smell gas, leave the home straight away, do not use switches, and call FortisBC at 1-800-663-9911 from outside. If a carbon monoxide alarm sounds, everyone goes outside and you call 911. Boiler replacement involves gas and venting and must be done by a Technical Safety BC licensed gas fitter with the correct permit.
Because the boiler is only part of the job. Venting, access, pipework, the number of zones and whether you want a combi all change the work, which is why a short assessment comes before a quote.
No. It is a ballpark, not a quote. The CANRO office confirms the figure after a short assessment and a written quote follows before any work is done.
In many cases yes. Cast iron is long-lived, and the new boiler is sized to work with it. The technician checks the loop and pipework condition before recommending anything.
Gas boiler replacement requires a gas permit and inspection. The contractor arranges it, and the permit cost is typically a ballpark of $75 to $200.
Scope decides it. A like-for-like swap in an accessible room is quicker than a job with new venting and pipe changes. The office can give an expected duration after the assessment.
Warranty terms are set by each manufacturer, so verify your certificate. We do not promise terms, and a quote should explain what is covered by the manufacturer and what by the installer.
