A look at what makes replacing an IBC SFT Superflow tankless unit in a White Rock home different from an inland Metro Vancouver install.

Quick answer
Replacement makes sense once an IBC SFT Superflow's heat exchanger has failed, corrosion has compromised the vent terminal beyond a simple fix, or repairs are becoming frequent on an aging unit. In White Rock, the coastal salt exposure and the city's own permitting process (separate from Surrey) are both worth planning for before the job starts.

On a replacement job in White Rock, particularly for homes within a few blocks of the waterfront, we pay close attention to how the new vent terminal is positioned and sealed, since salt-laden air off the water accelerates corrosion on exterior metal fittings faster than it would on an equivalent inland install. This doesn't change the SFT Superflow unit itself, but it does affect material choices and sealing practices at the exterior penetration, and it's worth discussing with your technician if your old unit's vent terminal showed corrosion before failing.
White Rock's older housing stock - a lot of bungalows and modest 1970s-80s homes on lots that slope toward the water - also means mechanical rooms were often built for a tank-style heater originally, so a tankless replacement sometimes needs a closer look at existing venting routes and gas line sizing than a newer build would.
White Rock issues its own gas permits separately from Surrey, even though the two are adjacent - a detail that matters for scheduling but not for the actual technical work, which follows the same Technical Safety BC licensing requirements everywhere in the province. The crew isolates and removes the old unit, inspects the wall penetration and existing vent run, sets the new unit, reconnects gas, water, vent, and condensate, then pressure-tests and commissions it before confirming hot water delivery throughout the house.
Where the vent terminal exits an exterior wall facing the water, proper sealing and terminal placement matter more here than they would inland, since even a well-installed unit will see faster wear on exposed exterior hardware in a salt-air environment. This is a conversation to have with your technician at install time, not something to address after the fact once corrosion has already started.
Tankless install runs $3,500 to $7,500 as a 2026 public-market ballpark, not a quote. Where a White Rock job lands in that range depends on how much of the existing venting and gas piping is reusable, whether the mechanical room needs any modification, and whether corrosion has affected more than just the unit itself. CANRO's certified technicians confirm your actual number after assessing the property in person.
Safety note
If you smell gas, see rust staining or scorching near the vent terminal, or suspect carbon monoxide, leave the home immediately and call FortisBC's emergency line at 1-800-663-9911 before doing anything else.
Not necessarily - proper sealing and material choices at install time can meaningfully slow the corrosion process compared to an older install, though coastal exposure will always be a factor here.
Yes, White Rock is its own municipality with its own permitting process, distinct from Surrey even though they border each other.
Sometimes, depending on the home's layout and existing gas and water line routing - worth raising with your technician during the assessment.
Yes, replacement is a natural point to reassess capacity if your original unit was undersized or your hot water demand has increased since it was installed.
Removal and responsible disposal of the old unit and any replaced venting is handled as part of the job.
A technician can recommend an inspection interval suited to your specific proximity to the water rather than a one-size-fits-all schedule.
