What it costs to install a new gas storage water heater in a Shaughnessy home, and the venting considerations unique to older properties.
Tell us what you need—we’ll call you back fast.
Quick answer
A new gas water heater installation in Shaughnessy typically costs $1,800-$3,200 for a standard vented tank, or $2,500-$4,500 if power venting is required — a ballpark based on 2026 public market data, not a quote, that CANRO's certified technicians confirm on site. Homes where the tank previously shared a chimney with an older boiler often need venting reworked as part of the install.

Many Shaughnessy properties were built before direct-vent equipment existed, so their original venting was designed around a chimney serving multiple gas appliances at once. Installing a new water heater in that kind of system means confirming the chimney is still correctly sized and drafting properly for whatever else is venting through it — a detail that's less of a factor in a newer home where each appliance typically has its own dedicated vent.
Larger Shaughnessy homes with more bathrooms sometimes benefit from stepping up tank size at replacement time, which a technician can discuss based on actual household hot-water use rather than just matching what was there before.
| Item | Typical range (CAD) |
|---|---|
| Standard atmospheric-vent tank, installed | $1,800-$3,200 |
| Power-vent tank or venting changes required | $2,500-$4,500 |
| Municipal gas/plumbing permit | $75-$200 |
The City of Vancouver requires a permit for water heater installation, and CANRO manages pulling and passing that inspection, which on an older home often includes confirming venting meets current code rather than just being grandfathered from decades ago.
Think of a larger Shaughnessy household with four bathrooms whose aging, smaller-capacity tank can no longer keep up with morning demand. During the assessment, the technician discusses stepping up to a larger tank size, confirms the existing chimney venting — shared with no other appliance in this case — can support the change, and completes the installation along with the City of Vancouver permit inspection. The homeowner ends up with noticeably better hot water availability during peak-use hours without having to convert to a fundamentally different system.
Tank sizing for a larger Shaughnessy household and venting compatibility with the home's existing chimney or exterior wall routing are both things a technician needs to see in person before quoting confidently. CANRO's assessment walks through both before giving you a firm figure for your specific project.
Safety note
If you ever smell gas, hear a hissing sound near the meter or a gas appliance, or a carbon-monoxide alarm sounds, leave the home immediately, do not flip switches or light anything, and call FortisBC's emergency line at 1-800-663-9911 from outside before calling anyone else.
If the chimney also serves another appliance, its sizing and draft have to work correctly for both, which a technician verifies rather than assuming the old configuration is still appropriate.
It's worth discussing with a technician based on actual usage — more bathrooms and higher simultaneous demand can justify a larger tank, but it's assessed rather than assumed.
Yes, the City of Vancouver requires a permit for gas water heater installation.
A straightforward swap is usually a half-day; venting changes on an older system can extend that.
Yes, and a technician can walk through the options and what each means for venting requirements during the assessment.
Yes, removal and disposal of the old unit is part of a standard installation.
It depends on bathroom count and household size rather than the home's overall square footage; a technician calculates recommended capacity based on actual usage patterns, not just how big the house is.
It can factor into fitting selection and whether any pressure-related components are recommended alongside the new tank, which a technician checks during the assessment.
Timing depends on current scheduling demand; a straightforward replacement can often be booked within a week or two outside of peak fall season.
Yes, once the City of Vancouver permit inspection passes, the technician walks you through the completed installation and how to identify normal operation versus anything worth calling about.
