Older Capitol Hill homes often have water heaters original to a past renovation, and CANRO explains what to check before a straightforward or upgraded replacement.

Quick answer
In Capitol Hill's older character homes, water heater replacement often surfaces questions about whether the existing tank location, gas line, and venting still make sense, especially if the homeowner is considering switching to tankless. A licensed tech checks the whole setup, not just the tank, before recommending a replacement path.

Most replacement calls in Capitol Hill come from one of two situations: a tank that is visibly failing, leaking at the base, or producing rusty water, or a homeowner planning ahead because they know their unit is well past the typical 10 to 15 year service life for a standard gas tank. Character homes here sometimes have a water heater tucked into an awkward spot from a past renovation, which is worth flagging before replacement, since the same tight spot may or may not work well for a different type of unit.
On a sloped lot, access to the mechanical space can also be a factor. If the water heater sits in a crawlspace or a lower level reached from outside, that affects how straightforward a swap is, and worth mentioning when booking the visit.
| Factor | Favours tank | Favours tankless |
|---|---|---|
| Existing space is tight or awkward | No, still needs tank clearance | Yes, compact wall mount |
| Budget is the primary concern for a like-for-like swap | Yes, generally lower upfront cost | No, higher upfront cost |
| Household added a secondary suite or laneway home | May need a second tank | Can often be sized for combined demand |
| Existing gas line is undersized | No change needed for a tank swap | Line likely needs upsizing |
We walk homeowners through this tradeoff honestly rather than defaulting to whichever option is easier for us to install that day.
A straightforward tank swap, where the gas line, venting, and location all stay the same, is usually a single-visit job. Switching types, or dealing with an awkward access location on a sloped lot, adds time and should be scoped in advance rather than discovered partway through. Ballpark cost: a tankless install typically runs $3,500 to $7,500, and if the underlying issue turns out to involve a whole boiler-based hot water system rather than a standard tank, that replacement is priced individually, always confirmed after we have actually seen the equipment.
Safety note
If you ever smell gas (a rotten-egg odour) or suspect a carbon monoxide problem, leave the home right away, do not flip switches or light anything, and call FortisBC at 1-800-663-9911 from outside before calling anyone else. Any gas connection, venting change, or pressure work on a boiler or water heater in BC must be done by a Technical Safety BC licensed gas fitter; CANRO carries gas licence LGA0043870 and boiler licence LBP0046450.
Active leaking at the tank base typically means the tank has failed internally, so yes, replacement is the appropriate response rather than a repair, and it is worth arranging fairly promptly to avoid water damage.
It depends on your gas line capacity, available space, and household hot water demand. We assess your specific home rather than recommending tankless universally, since a straightforward tank swap is the better fit for some households.
It adds time and sometimes a bit of cost to the job, but it is a normal part of many older Capitol Hill homes and not something that prevents replacement, just something to plan for.
Tankless units vent differently and need a suitable nearby exterior wall for termination, which is not always the same spot that worked for a tank. We assess this on site before recommending a switch.
Generally 10 to 15 years for a standard tank, though this varies with water quality, usage, and maintenance. We do not guarantee a specific lifespan for any individual unit.
