Edgemont's larger custom homes with multiple bathrooms often outgrow a single storage tank, and CANRO sizes and installs tankless systems to match.

Quick answer
A tankless gas water heater in an Edgemont home replaces a storage tank with an on-demand unit, well suited to the neighbourhood's larger custom homes where several bathrooms can draw hot water at the same time. Vent placement needs to account for the treed, elevated lots common in Edgemont, and gas line capacity should be checked against the home's total appliance load.

Edgemont's custom-built homes tend to have more bathrooms and larger households than the Metro Vancouver average, and a fixed storage tank can struggle to keep pace when several showers or a shower and laundry run at the same time on a busy morning. A properly sized tankless system heats water continuously, which removes that ceiling on simultaneous demand.
Some of these larger homes also run several gas appliances, a boiler, a fireplace, and a range, all drawing from the same service, so confirming the home's total gas capacity before adding a tankless unit's peak draw is an important step we don't skip.
A household with a home gym, a hot tub fill line, or a mudroom sink used after outdoor activity adds fixture demand that isn't always obvious from a standard bathroom count, and we ask about those extras during the initial assessment so the unit is sized for how the home is actually used rather than a generic estimate. Skipping that step is the single most common reason a homeowner later feels an otherwise properly installed tankless unit doesn't quite keep up.
| Factor | Why It Matters in Edgemont |
|---|---|
| Simultaneous fixture count | Larger homes often run several bathrooms at once |
| Total gas appliance load | Boiler, fireplace, and range may share the same service |
| Vent wall exposure | Treed lots can affect debris accumulation at termination |
| Elevation and cold snap exposure | Incoming water temperature runs colder in winter |
Incoming water temperature matters more for tankless sizing than for a storage tank, since a tankless unit has to raise the water temperature in real time rather than drawing from a pre-heated reserve. Edgemont's colder winter conditions mean incoming water runs a bit cooler than in a milder part of the region, which we factor into the unit sizing.
Most installations in larger Edgemont homes require confirming, and often upsizing, the gas line to handle a tankless unit's peak draw alongside the home's other gas appliances. Venting is routed to an exterior wall with attention to prevailing wind and, on well-treed lots, a location less prone to leaf or needle accumulation that could restrict airflow over time.
Installation runs in a ballpark of $3,500 to $7,500, with larger homes needing gas line upsizing for multiple appliances typically landing toward the higher end. This is a ballpark, not a quote, until a technician has assessed the property's full gas load and venting options and confirmed unit selection against the home's real-world simultaneous demand.
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.
Often yes, particularly where several bathrooms can draw hot water at the same time, since a properly sized tankless unit removes the ceiling a fixed tank would otherwise hit during peak demand.
They can. If your home runs a boiler, gas fireplace, and range on the same service, we assess the total gas load before sizing the tankless unit and confirm the line can handle everyone running at once.
Yes, colder incoming water temperature in winter means the unit has to work harder to reach target temperature, which is factored into sizing rather than using a generic estimate.

They can, since leaves and needles may accumulate near an exterior vent termination over time, so we choose placement and recommend periodic checks accordingly.
