When a straight chimney vent isn't an option, a power-vent tank pushes exhaust sideways instead — here's what that costs in West Vancouver.

Quick answer
A power-vent gas water heater in West Vancouver typically costs $2,500 to $4,500 installed, above the $1,800 to $3,200 range for a standard atmospheric-vent tank, because of the added blower, electrical work, and sidewall vent installation. That's a 2026 public-market ballpark, not a quote — CANRO's certified gas technicians confirm the real number after assessing your mechanical room and venting options.

A power-vent tank adds a small electric blower to the top of an otherwise standard gas water heater, pushing exhaust sideways through a wall under mechanical force rather than relying on natural draft up a chimney. The added cost covers that blower, the dedicated electrical outlet it needs nearby, and the sidewall vent kit and wall penetration, sealed and flashed through whatever exterior material the home has.
| Scenario | Typical installed range |
|---|---|
| Standard atmospheric-vent tank, existing chimney reused | $1,800 – $3,200 |
| Power-vent tank or new sidewall vent install | $2,500 – $4,500 |
| Municipal gas/plumbing permit | $75 – $200 |
West Vancouver's split-level and hillside homes frequently place the mechanical room on a lower floor facing the slope, well away from any chimney and sometimes with no straight vertical path to a roofline at all, which makes sidewall power venting the practical, and sometimes the only workable, option. Renovated and rebuilt homes in the area also often decommission an original shared chimney once the furnace is upgraded to a sealed-combustion model, leaving the water heater without a usable flue and needing its own power vent.
Longer, more complex vent runs common in these larger hillside properties are also part of why power-vent installs here sometimes land toward the upper end of the range, especially where the run has to navigate around framing or plumbing to reach a suitable exterior wall.
When a power-vent tank stops firing, the blower motor or the pressure switch confirming it's running are the most likely culprits, not the tank itself. On a tank under roughly ten years old, repairing those components is usually the right call; past that age, or with any sign of tank corrosion, replacement is the more sensible path rather than adding new venting parts to an aging tank.
Because hillside layouts vary so much, CANRO prices power-vent installs after seeing the mechanical room and the proposed exterior termination in person. Let the technician know whether the existing chimney is still active or has already been decommissioned, since that detail alone often determines which end of the range applies.
If your home has undergone a furnace replacement in recent years, mention roughly when that happened — it's one of the fastest ways to confirm whether the water heater's old vent path is still usable or whether power venting is now the only realistic option.
Day to day, a power-vent tank behaves the same as any other gas water heater — the blower runs briefly before and during firing and isn't something most households notice after the first few days. Keeping the exterior termination clear of landscaping, snow, or debris is the one piece of upkeep worth checking periodically, since a blocked termination is one of the more common, and easily preventable, causes of a service call.
Safety note
Power venting moves combustion exhaust and carbon monoxide under mechanical force, and installation or repair must be performed by a Technical Safety BC licensed gas fitter. If you ever smell gas or suspect a venting fault, leave the home immediately and call FortisBC at 1-800-663-9911 from outside.
The added cost comes from the blower assembly, the dedicated electrical outlet it needs, and cutting and sealing a sidewall vent through the exterior wall.
Mechanical rooms on a lower level facing a slope frequently have no straight path to a chimney or roofline, making a sidewall power vent the practical option.
Yes — if the furnace that shared the chimney is replaced with a sealed-combustion model, the water heater often loses a safe, adequately drafting flue and needs its own power vent.
A District of West Vancouver gas and plumbing permit is required, typically $75 to $200.
Usually yes, especially on a tank under about ten years old — the blower and pressure switch are the most common points of failure and are repairable independent of the tank.
Yes, the $90 to $150 service call is credited toward whichever work you approve.
