Quick answer
Replacing a gas hot water tank in Marpole typically costs $1,800 to $3,200 for a standard atmospheric-vent tank, or $2,500 to $4,500 if power-venting or venting changes are needed, plus a City of Vancouver gas permit of $75 to $200. That's a ballpark based on 2026 public market data, not a firm quote — CANRO's office books a short assessment so a certified gas technician can confirm exact pricing for your home.

Most replacement calls follow the usual signs, rust-tinged water, a puddle forming at the base of the tank, or a unit simply reaching the point in its second decade where reliability starts to drop off. In Marpole's older character homes, particularly the 1930s and 1940s stock close to the historic core, a tank replacement sometimes becomes an opportunity to update the vent path if the original setup no longer cleanly meets current code after decades of incidental changes to the home.
In the newer rental and mid-rise buildings that have gone in along Cambie and Granville, replacement is usually a more straightforward like-for-like swap once the original tank reaches the end of its service life.
| Scenario | Typical range |
|---|---|
| Standard atmospheric-vent tank | $1,800–$3,200 |
| Power-vent tank or venting changes needed | $2,500–$4,500 |
| Gas permit | $75–$200 |
A number of Marpole's oldest homes, some dating back nearly a century, have had their chimneys or venting altered over the years as heating and water heating equipment was updated piecemeal, and by the time a tank replacement comes up, the existing vent path doesn't always meet current code cleanly. That's often when a power-vent tank, which uses a small fan to push exhaust out through a wall rather than relying on a chimney, becomes the practical solution, which is part of why replacement cost in these older homes sometimes lands toward the higher end of the range.
The City of Vancouver requires a gas permit and final inspection for tank replacement, the same as for any gas appliance install.
A tank under roughly eight years old with a single isolated issue, like a failed thermocouple or T&P valve, is almost always worth repairing rather than replacing. Once a tank shows rust-coloured water, moisture at the base of the tank body itself rather than a fitting, or is simply past its typical service life and needing a second repair, replacement becomes the more sensible option, since continuing to repair an aging tank close to failing outright risks a more disruptive leak later on.
Safety note
Hot water tank replacement involves gas connection and venting work that must be performed by a Technical Safety BC licensed gas fitter. If you smell gas near the tank, leave the home immediately and call FortisBC at 1-800-663-9911 from outside.
Rust-coloured water, a leak from the tank body itself, or an age past ten to twelve years combined with a new issue are the usual signs a technician looks for when recommending replacement.
If the existing vent path or chimney no longer meets current code, particularly common in older Marpole homes with decades of incidental changes, a power-vent tank is often the practical replacement option.
Yes, a gas permit through the City of Vancouver is required, along with a final inspection once the replacement is installed.
A straightforward like-for-like swap is often completed in a few hours, while a job requiring venting changes typically takes longer.
Tank sizing depends on household size and fixture count; a technician can recommend the right capacity based on your typical hot water demand.
Usually yes, though if your household's hot water needs have changed since the original tank was installed, a technician may suggest a different capacity.
