Garage-installed tanks are common on Heritage Mountain, and that placement is one of the bigger factors in whether a replacement lands at the low or high end.

Quick answer
Replacing a gas hot water tank in Heritage Mountain generally runs $1,800–$3,200 for a standard atmospheric-vent unit, or $2,500–$4,500 if power-venting or code changes are needed, plus a City of Port Moody permit around $75–$200. Numbers like these are useful for budgeting, but they're a 2026 market-data ballpark, not a quote; CANRO's certified gas technicians confirm exact pricing once they've assessed the specific install or repair.

These are sloped lots with attached garages and finished lower levels, and on a fair number of Heritage Mountain properties the water heater or the boiler sits in the garage rather than an interior mechanical room, which is a layout common across 1980s-and-90s Tri-Cities construction.
A like-for-like swap with existing atmospheric venting still usable runs $1,800–$3,200. If the existing venting doesn't meet current code, or a power-vent model is needed because of how the garage or utility space is laid out, that moves to $2,500–$4,500. A City of Port Moody permit, typically $75–$200, applies regardless.
| Scenario | Typical installed cost |
|---|---|
| Standard atmospheric-vent swap | $1,800–$3,200 |
| Power-vent or venting/code changes needed | $2,500–$4,500 |
| City of Port Moody gas permit | $75–$200 |
A tank leaking from the tank body itself always means replacement. Short of that, age drives the decision: gas tanks generally run 8–12 years, and Heritage Mountain's original-era tanks that are still in service are typically well past that point, which usually tips the scale toward replacing rather than repairing whatever's currently failing.
Because a garage isn't insulated the way an interior room is, equipment placed there is exposed to real cold during a hard winter snap — pipes and fittings near an exterior wall or garage door can get close to freezing, which is a factor CANRO's techs specifically check on service calls out here that inland Vancouver properties rarely raise.
General rebate and financing programs through FortisBC and CleanBC sometimes apply to qualifying gas water heater replacements, though eligibility and terms change, so it's worth confirming current details with the CANRO office rather than assuming a past program still applies. Financing options can also help spread a garage tank replacement over time rather than requiring the full amount upfront, which is worth asking about especially if the replacement is happening sooner than planned due to an unexpected failure.
Safety note
Natural gas equipment work in BC must be done by a Technical Safety BC licensed gas fitter. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you ever smell gas, hear a hissing sound near a gas line, or suspect a carbon monoxide problem, leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 from outside — do not try to diagnose it yourself.
Sometimes, mainly if freeze protection or venting updates are needed — the base swap cost itself is similar either way.
Yes, for gas water heater replacement regardless of location within the home.
Code requirements around clearances and vent sizing have evolved since these homes were built in the 1980s and 90s, so a straight swap sometimes needs updating to comply.
A straightforward swap is a few hours; venting or code-driven changes can extend the job to a full day.
Usually yes, within the mechanical space and gas line capacity — CANRO checks both before recommending a size.
Roughly 8 to 12 years, similar to elsewhere in Metro Vancouver, though garage exposure to temperature swings can affect wear over time.
