Quick answer
Installing a gas tankless water heater in Lynnmour typically costs $3,500 to $7,500, plus a permit. That's a ballpark based on 2026 public market data, not a quote — CANRO's technicians confirm the exact number after assessing your gas line, venting path, and mechanical room.

Most Lynnmour tankless installs are conversions from an existing tank rather than first-time setups, and the scope of that conversion depends heavily on the home's age. Older detached homes, some dating from before Lynnmour's more recent townhouse infill, typically need a gas line resized and a new venting path cut through to an exterior wall. Newer townhouse construction sometimes has more of that infrastructure already closer to modern standard, which can keep costs toward the lower half of the range.
| Cost component | Typical range |
|---|---|
| Tankless unit + standard install | $3,500–$7,500 |
| Gas permit | $75–$200 |
Tankless suits households with steady, spread-out demand — back-to-back showers, laundry, and a dishwasher running through a busy morning. If an existing tank is under ten years old and working well, the conversion cost is a harder sell purely for efficiency; it's more often chosen for endless hot water or to reclaim mechanical closet space, especially valuable in Lynnmour's more compact newer construction.
Because gas line and venting scope vary so much between Lynnmour's older and newer homes, CANRO always assesses in person before quoting a tankless install rather than pricing sight unseen.
A common call in this neighbourhood involves an older detached Lynnmour home where the existing gas line was sized decades ago for a much lower overall household gas demand — just a furnace and a tank water heater, say — and adding a tankless unit's higher peak draw means the whole line from the meter needs reassessing, not just the run to the water heater itself. That's a bigger scope than some homeowners expect going in, which is exactly why CANRO's in-person assessment covers the full gas supply picture rather than just the water heater location.
In newer Lynnmour townhouse construction, gas demand was typically planned with more headroom from the start, which tends to keep tankless conversion costs closer to the lower end of the range.
Safety note
If you ever smell gas, hear a hissing sound near the appliance, or your carbon monoxide alarm goes off, get everyone out of the house first and call FortisBC at 1-800-663-9911 from a safe location before doing anything else. Gas boiler and water heater work in BC must be performed by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450.
Most were built with gas line and venting sized for a tank, not a tankless unit's higher peak draw, so upsizing that infrastructure is usually part of the job.
Sometimes, if the gas line and venting are already closer to modern standard, though each unit still needs individual assessment.
Most households see some reduction from eliminating standby heat loss, though the amount depends on usage and CANRO doesn't quote a specific savings figure.
Yes, through the District of North Vancouver, typically $75–$200, included as part of the job.
It's more often chosen for endless hot water or space savings than pure efficiency if the existing tank is under ten years old and working well.
Sometimes, if the location allows for proper venting to an exterior wall; if not, CANRO will discuss the best alternative location during the assessment.
CANRO's licensed technicians service tankless units generally; ask the office about specific brand experience relevant to your household's equipment.
Older homes were often sized for lower overall household gas demand, and a tankless unit's higher peak draw can mean the line from the meter, not just the water heater run, needs to be reassessed.
Generally yes — newer Lynnmour townhouse construction was typically planned with more gas capacity headroom from the start, which tends to keep conversion costs lower.
