Quick answer
A tankless water heater repair in Deep Cove typically totals $250 to $900, with the $90–$150 diagnostic visit credited toward that number if you proceed with the fix. These are 2026 ballpark figures based on public market data, not a quote — the exact cost is confirmed once a certified technician has read the unit's fault history in person.

Calls on tankless units in Deep Cove tend to cluster around two issues — a fault code that shuts the unit down outright, or inconsistent water temperature that comes and goes depending on how many fixtures are running. Both start with the same first step: pulling the fault history off the unit's control board and checking gas supply and venting before anything gets replaced.
Ignition faults tend to be quicker, lower-cost fixes than control board issues. Flow or temperature inconsistency often traces back to scale inside the heat exchanger, particularly on a unit that hasn't had a descaling service in a few years — the North Shore's soft mountain water slows this process compared to harder water sources, but it doesn't stop it entirely.
A tankless unit still under warranty with one isolated fault is almost always worth repairing outright — the fix is a small fraction of a new install's cost. That calculation shifts on an older, out-of-warranty unit that's showing a second unrelated failure within a short window, particularly on hillside properties where the unit has had years of North Shore rainfall exposure affecting its exterior vent components. At that stage, your technician will lay out the honest comparison between continuing repairs and putting that spend toward a new install.
If your household has grown since the tankless unit was first installed — an addition, a secondary suite, more people showering back to back — recurring performance complaints may actually be a sizing issue rather than a mechanical fault, which is worth mentioning to your technician before assuming a part needs replacing.
A lot of the repeat repair calls CANRO sees on tankless units trace back to a descaling service that simply never happened. Manufacturers generally recommend descaling on a schedule based on water hardness and usage, and while the North Shore's mountain-reservoir water is comparatively gentle on these units, a household with heavy hot water use can still benefit from staying on that schedule rather than waiting for symptoms to show up. Asking your technician to set a reminder or add it to an annual visit is usually simpler than trying to track it yourself.
If your unit has already thrown the same fault code more than once, mention that history when you call — it can point the diagnosis toward the actual root cause faster than starting from scratch each time.
A CANRO technician connects to the unit's diagnostics, checks gas pressure and venting condition, and explains the actual fault in plain terms before quoting the repair. All gas-side work is completed by a Technical Safety BC licensed gas fitter. Most repairs finish in the same visit; parts for a less common brand occasionally require a short lead time to arrive.
Safety note
Diagnosing or repairing the gas or venting components of a tankless water heater must be done by a Technical Safety BC licensed gas fitter — do not attempt this yourself. If the unit smells like gas, is sooting, or a carbon monoxide alarm sounds, leave the home and call FortisBC at 1-800-663-9911 from a safe location.
No — CANRO credits the $90–$150 diagnostic visit toward the repair if you proceed with the work, so it's not charged twice.
That's often related to scale inside the heat exchanger on a unit that's overdue for descaling, though a technician confirms this against the unit's actual fault history rather than assuming.
A single fault under warranty is almost always worth repairing; an out-of-warranty unit with repeated unrelated failures is where your technician will walk through the honest repair-versus-replace comparison.
Yes — an addition or extra household members can push demand past what the unit was originally sized for, which shows up as performance complaints rather than an outright fault.
Exterior vent components take more weathering from the North Shore's heavy rainfall over the years, which is a factor a technician checks on any repair call at an older install.
