Quick answer
A gas water heater in a Fairview home should be replaced once it's leaking from the tank body, showing rust-coloured water consistently, or approaching the end of its typical working life, and the choice between a new storage tank or a tankless unit depends on available space, venting path, and household hot water demand. A licensed technician assesses the existing venting, gas line, and mechanical room before recommending either option.

The clearest sign is water pooling at the base of the tank itself, which usually means the tank has corroded through and needs replacement rather than repair. Rust-coloured hot water that doesn't clear after running the tap for a minute, a popping or rumbling sound from sediment buildup, or a pilot light that won't stay lit are all signs worth having checked before the unit fails outright, often during a cold snap when you need it most.
Fairview's mix of housing ages means we see both very old original tanks in unrenovated character homes and newer units in recently built infill that fail early due to a manufacturing defect or installation issue, so age alone isn't always the deciding factor.
| Home Type | Typical Constraint | Common Choice |
|---|---|---|
| Character house, unrenovated basement | Low ceiling height, limited floor space | Tankless or compact tank |
| Character house with basement suite | Two households sharing hot water demand | Larger tank or properly sized tankless |
| Newer infill or rowhouse | Small dedicated mechanical closet | Tankless, space-driven |
A storage tank remains the simpler, lower-upfront-cost option and is often the right call for a straightforward like-for-like swap, while tankless suits homes where floor space is tight or where a basement suite adds enough demand that a tank would need frequent reheating cycles.
Every replacement starts with confirming the gas line size and venting still meet current code, since older Fairview homes sometimes have venting configurations that predate current standards and need updating as part of the swap. We also check the seismic strapping on the old tank, since many older character homes never had this added, and it's required on new installations.
A tankless replacement in Fairview typically runs in a ballpark of $3,500 to $7,500, while a storage tank replacement varies by size, venting, and access, and is quoted after a short in-home assessment rather than over the phone. These figures are ballparks, not quotes, and every Fairview home's mechanical room layout affects the final number.
Before calling for service, it's worth glancing at the base of the tank for any standing water and checking whether the pilot light or status indicator is lit, since that quick look can help a technician arrive prepared with the right parts. It's not worth attempting to relight a pilot repeatedly if it keeps going out, since that pattern usually points to a failing thermocouple or a venting issue that needs a proper inspection rather than a quick fix.
Safety note
If you ever smell gas, hear hissing near the boiler or water heater, notice a yellow or flickering burner flame, soot around a draft hood, or a stale, headachy feeling near the mechanical room, leave the house immediately and call FortisBC at 1-800-663-9911 from somewhere safe. Gas piping, venting, and combustion appliances in BC must only be installed or serviced by a Technical Safety BC licensed gas fitter.
Most gas storage tanks provide roughly a decade or more of reliable service, though actual lifespan depends on water quality, usage, and maintenance rather than a fixed number.
It depends on your space and venting situation; a technician can walk through both options during the same visit rather than defaulting to a like-for-like swap.
It should be addressed quickly to prevent water damage, and the gas supply should be shut off at the appliance valve if you're comfortable doing so, but it's not a gas safety emergency unless you smell gas.
Yes, gas water heater replacement requires a permit pulled by the licensed gas fitter doing the work, which CANRO handles as part of the installation.
It can, provided the unit is sized for combined peak demand from both households; undersizing is the most common complaint we hear about shared setups.
