What tankless water heater installation involves in Uptown New Westminster's mix of early-1900s homes and newer condos.
Tell us what you need—we’ll call you back fast.
Quick answer
Installing a tankless water heater in Uptown New Westminster means confirming the gas line can handle the unit's higher demand, routing new sidewall venting through an exterior wall, and finding a workable mounting location — which in this neighbourhood's older homes often means a compact basement mechanical room that wasn't originally designed around modern appliance clearances. Newer condo and townhome construction in the area typically has more straightforward mechanical spaces to work with.

A meaningful share of homes in Uptown date from the early 1900s through the postwar decades, and basements from that era were built for a coal-fired or early gas furnace, not for the clearance and venting a modern tankless unit needs. That doesn't rule out tankless — it just means an installer needs to plan the mounting location and venting route carefully within an older foundation's layout rather than assuming a standard modern basement configuration.
Newer condo and townhome construction elsewhere in the neighbourhood tends to have simpler, more accessible mechanical closets built to current code from the start, which generally makes tankless installation more straightforward in those units.
| Home type | Sizing note |
|---|---|
| Older character home, 1–2 bathrooms | Standard tankless unit usually sufficient once gas line is confirmed |
| Renovated home with added bathrooms or a suite | Size for combined fixture count or consider a second dedicated unit |
| Newer condo or townhome | Simpler mechanical space; sizing based on unit's fixture count |
As with sizing anywhere in Metro Vancouver, winter incoming water temperature is colder than summer and should be the basis for sizing rather than warm-weather performance, so the household doesn't notice a drop in output during the coldest months.
The work requires a permit through the City of New Westminster and must be carried out by a Technical Safety BC licensed gas fitter. CANRO holds gas licence LGA0043870. In an older home where the gas line needs upsizing from the meter, the permit and inspection process covers that upgrade as well as the appliance connection itself.
Ballpark, not a quote: a tankless installation requiring new venting and gas line work typically falls in the $3,500–$7,500 range, with the higher end more likely in an older home needing a gas line upgrade. A written quote after an in-home assessment is the only reliable figure for your specific property.
If your basement is also part of a renovation, whether that's finishing an unfinished space or adding a secondary suite, it's worth having the tankless installation planned alongside that broader project rather than treated as a separate later step. Coordinating the gas line, venting, and mounting location with the rest of the renovation avoids the extra cost and disruption of opening finished walls a second time to accommodate the water heater after the fact.
Safety note
If you smell gas or suspect a carbon monoxide problem, leave the home immediately and call FortisBC at 1-800-663-9911 from outside before doing anything else. Never try to relight a pilot or reset a gas appliance yourself if you smell gas.
Often yes, since a wall-mounted tankless unit takes up far less floor space than a storage tank, though an installer needs to plan the venting path carefully within an older foundation's window and wall layout.
It's fairly common in older homes, since original gas lines were often sized for a single furnace and tank together. A licensed installer checks this before quoting the job.
Yes, many homeowners here choose tankless during a renovation specifically because it can be sized to cover added fixtures without needing a second bulky storage tank.
Newer construction typically has a purpose-built mechanical closet that's more straightforward to work with, while older homes need more careful planning around existing basement layout and gas line capacity.
Yes, a permit is required for the gas and venting work, and the installation must be completed by a licensed gas fitter so it can be properly inspected.
