Vancouver's mix of pre-war character homes and narrow infill lots is the main reason IBC boiler installation quotes vary so much.

Quick answer
Installing an IBC boiler in a Vancouver home generally runs $6,500 to $14,000 or more, with a full replacement at $7,500 to $15,000 or more, as a 2026 ballpark from public market data rather than a quote for your address. Vancouver's stock of pre-war character homes, Vancouver Specials, and narrow infill lots each change the job differently. CANRO's certified technicians confirm the actual figure after walking through the house.

A pre-war character home on the east side often still has its original chimney chase and a scattering of cast iron radiators fed by a boiler that predates the current owner. Getting a sealed-combustion IBC unit into that basement generally means running new vent pipe through an exterior wall rather than reusing the old masonry chimney, since condensing boilers vent through a dedicated pipe, not an open flue.
A Vancouver Special or a lot with a laneway house behind it changes the job in a different way — there's often less room to manoeuvre equipment into the basement, the vent terminal has to clear windows and property lines within a few feet, and the extra hot water draw from a laneway suite sometimes pushes the sizing conversation toward a larger unit.
| Item | Ballpark (2026) | Notes |
|---|---|---|
| IBC boiler installed, typical range | $6,500–$14,000+ | Straightforward swap with reusable venting sits at the low end |
| Full replacement incl. old unit removal | $7,500–$15,000+ | Applies when old boiler, venting, and sometimes piping all come out together |
If the current boiler is under about ten years old and the fault is a single part — a pump, a valve, a sensor — repair almost always wins on cost. Once a character home's original boiler needs a heat exchanger or a second major repair inside a year or two, the math generally tips toward replacing it with a new IBC unit instead of continuing to patch an aging system.
The City of Vancouver requires a mechanical permit and inspection for any new boiler installation, and the inspector checks vent clearances, gas line sizing, and combustion safety before signing off. A Technical Safety BC-licensed gas fitter handles the gas side of the permit; CANRO manages both as part of the job.
Safety note
If you ever smell gas, hear a hissing sound near the boiler, or a carbon monoxide alarm goes off, leave the house right away and call FortisBC's emergency line at 1-800-663-9911 from outside before doing anything else. Don't try to relight a pilot, reset a gas valve, or investigate the smell yourself.
Condensing equipment across brands is generally priced in a similar range; the bigger cost driver in Vancouver is usually the house itself — its venting, gas line, and access — rather than the brand chosen.
Usually not directly, since condensing boilers vent through a dedicated pipe rather than an open masonry flue, so most character-home installs need new sidewall or roof venting.
About a day for a straightforward swap; a full replacement with new venting or gas line work can take one to two days.
It should be itemized separately in most quotes, since the fee is set by the city rather than the contractor.
It can, if the laneway suite draws hot water or heat from the same system, which your technician accounts for when sizing the new unit.
Sometimes — gas line upsizing or new venting are the most common additions, and your technician will flag these before finalizing a quote.
