Dundarave's mix of compact waterfront homes and larger hillside rebuilds both benefit from tankless hot water, and CANRO installs and vents to suit each property.

Quick answer
A tankless gas water heater in a Dundarave home replaces a storage tank with an on-demand unit, which is useful both in compact waterfront-area houses short on mechanical room space and in larger hillside homes with multiple bathrooms drawing hot water at once. Venting placement needs particular care on hillside lots given West Vancouver's exposure to wind-driven rain off the water.

In the smaller post-war homes closer to the waterfront village, the draw toward tankless is usually space. These houses often have compact mechanical rooms or crawlspaces where a bulky storage tank eats up room that could be used for storage or a laundry upgrade, and a wall-mounted tankless unit reclaims that floor space.
Higher up the hillside, larger rebuilt homes usually go tankless for capacity, since multiple bathrooms and a larger household can draw hot water simultaneously in a way a fixed tank can't always keep pace with, particularly during a busy morning.
West Vancouver sees more sustained rainfall and wind exposure than much of Metro Vancouver, and a vent termination on the wrong wall of a hillside home can take a direct hit from weather coming off the water. We assess wall orientation and prevailing wind exposure as part of the installation plan, not just the shortest distance to an exterior wall.
| Site Type | Key Consideration |
|---|---|
| Compact waterfront home | Mechanical room space, shorter vent run |
| Hillside rebuild | Multiple bathroom demand, wind-exposed vent walls |
| Steep or narrow access lot | Equipment delivery and installer access planning |
| Any Dundarave home | Gas line sizing to handle peak tankless draw |
Sizing starts with how many fixtures could realistically run hot water at once, which tends to be higher in the larger hillside homes than the smaller waterfront-area houses. Most installations also require checking and often upsizing the existing gas line, since tankless units draw noticeably more gas at peak than a conventional storage tank, and that step is easy to miss if a homeowner or a less experienced installer only focuses on the unit itself.
Installation runs in a ballpark of $3,500 to $7,500, with hillside homes needing gas line upsizing or a longer vent run typically landing toward the higher end. That figure is a ballpark, not a quote, until a technician has walked the property and reviewed the existing gas and venting infrastructure.
Timing also matters on a hillside lot with steep or narrow access, since delivering a wall-mounted unit and the tools needed for gas and vent work is more straightforward on a dry day than during a heavy North Shore rain event. Where access is genuinely difficult, we plan the visit around forecast weather rather than rushing a job that would be easier and safer done a day or two later.
Safety note
If you ever smell gas, hear a hissing sound near a gas line or appliance, or notice soot, a persistent headache, or a yellow or flickering burner flame near your boiler or water heater, leave the house immediately and call FortisBC at 1-800-663-9911 from somewhere safe. Gas piping, venting, and combustion appliances must only be installed or serviced by a Technical Safety BC licensed gas fitter.
Yes, particularly where mechanical room or crawlspace space is limited. A wall-mounted tankless unit frees up floor space that a storage tank would otherwise occupy.
Yes, West Vancouver's wind-driven rain off the water means a vent on an exposed wall can face more weather than one on a sheltered side, so we plan termination placement carefully on hillside lots.
Often, since tankless units draw more gas at peak demand than a typical storage tank. We check your existing line size during the assessment and include any needed upsizing in the quote.
Installation runs in a ballpark of $3,500 to $7,500, with hillside homes needing gas line or venting work landing toward the higher end. This is a ballpark, not a firm quote, until assessed.
Sustained rain and wind can push debris toward an exterior vent termination, especially on treed lots, so checking that the vent is clear is worth doing after major storms.
