Quick answer
Replacing a gas hot water tank in a Langley home typically runs $1,800 to $3,200 with a standard atmospheric vent, or $2,500 to $4,500 if power-venting or other venting changes are needed. That's a 2026 public market ballpark, not a quote — the CANRO office and our certified gas technicians confirm the real price after seeing your current setup and whether code has changed since it was installed.

A hot water tank replacement sounds like it should be one price, but the venting configuration makes a real difference. A standard atmospheric-vent tank replacing a like-for-like unit, where the flue and gas connection stay essentially the same, is the simpler and cheaper job. Power-vent tanks, which use a fan to push exhaust out through a wall rather than relying on natural draft up a flue, cost more to install because of the electrical connection the fan needs and the different venting path. Some Langley homes end up needing power-venting specifically because the original chimney or flue no longer meets current venting code, which turns a routine swap into a slightly bigger project.
Township of Langley acreages with older standalone flues sometimes fall into this category, where a tank that's due for replacement anyway also needs a venting update to bring the install up to current standard.
| Scenario | Typical range | Notes |
|---|---|---|
| Standard atmospheric-vent tank, like-for-like swap | $1,800–$3,200 | Most common replacement scenario |
| Power-vent tank, or venting/code changes required | $2,500–$4,500 | Includes fan-assisted venting and any related electrical work |
| Municipal gas permit | $75–$200 | Required through the Township or City of Langley |
| Diagnostic / sizing visit | $90–$150 | Confirms which scenario applies before a full quote |
A gas water heater replacement requires a municipal permit in both the Township and City of Langley, and it's an easy step to overlook when the job looks routine. The permit and inspection confirm the gas connection, venting, and pressure relief are set up correctly — worth insisting on even for a job that seems straightforward, since it's the same inspection that would catch a venting issue before it becomes a safety problem rather than after.
Replacing a tank on your own schedule, rather than after it has already failed, gives you room to compare options and book at a convenient time rather than the first available slot during a busy stretch. If your tank is already past 10 to 12 years old or showing early rust or sediment noise, it's worth getting a diagnostic visit booked now rather than waiting for the tank to force the decision on its own timeline.
Safety note
A gas hot water tank replacement involves gas line and venting connections that must be performed and permitted by a Technical Safety BC licensed gas fitter — CANRO holds gas licence LGA0043870. If you ever smell gas near the tank, leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 before doing anything else.
A power-vent tank uses a fan to push exhaust through a wall rather than relying on a natural-draft flue, which adds electrical connection work and a different venting path compared to a standard atmospheric-vent install.
Yes, a municipal gas permit is required through the Township or City of Langley for a hot water tank replacement.
It depends on your current flue setup and whether it still meets code — a technician can assess this during a diagnostic visit before quoting the replacement.
A standard like-for-like swap is usually completed in a single visit; a job requiring power-venting or code updates can take longer.
Replacing a tank showing rust, sediment noise, or age past 10 to 12 years before it actually leaks avoids the water damage and scramble that comes with an unexpected failure.
FortisBC and CleanBC programs sometimes apply to efficient gas water heater upgrades, but eligibility and terms change, so confirm current details rather than relying on a past program.
