Mary Hill homeowners looking at a tankless gas water heater usually want to know why it costs more than a standard tank before deciding if it's worth it.

Quick answer
A tankless gas water heater installed in a Mary Hill home typically runs $3,500 to $7,500, plus a $75-$200 gas permit. Treat that as a starting ballpark pulled from current public market data, because a certified CANRO technician still needs to walk through the mechanical room before the price is locked in. The higher cost versus a storage tank reflects the unit itself, venting requirements, and often gas line upsizing.

A tankless unit heats water on demand instead of storing a tankful, which means endless hot water but also a higher upfront cost than a standard storage tank. In Mary Hill, tankless units are a common upgrade when a homeowner is renovating a mechanical room or wants to free up crawlspace or closet floor space that a tank used to occupy.
| Item | Typical cost |
|---|---|
| Tankless unit, fully installed | $3,500-$7,500 |
| Gas permit | $75-$200 |
| Storage tank installation, for comparison | $1,800-$3,200 (standard) |
These are 2026 Metro Vancouver market ranges as a planning ballpark. CANRO confirms the exact installed price after a certified gas technician assesses your gas line capacity, venting, and hot water demand.
Gas line sizing is the biggest factor — tankless units need significantly more gas flow at peak than a storage tank, and many older Mary Hill homes need the gas line upsized to support one. Venting is another factor, since tankless units typically use different vent material than a standard tank and often route differently.
Tankless makes the most sense for households that want continuous hot water, especially with multiple bathrooms in regular simultaneous use, or where reclaiming a tank's floor space matters — common in Mary Hill's tighter crawlspaces and older mechanical closets. For a smaller household with modest hot water needs, a standard storage tank at a lower installed cost can be the more economical choice. A technician can walk through your household's actual usage to help make that call.
Because tankless units draw more gas at peak firing than a storage tank, a technician always checks the existing gas line size and the meter's total capacity before quoting — this is one of the most common reasons a Mary Hill tankless quote comes in at the higher end of the range. On the water side, Metro Vancouver's soft reservoir water is a genuine advantage for tankless units, since scale build-up inside the small heat exchanger is one of the main things that shortens a tankless unit's service life in hard-water regions.
CANRO's tankless installation includes the unit, gas line work as needed, venting, gas connection and pressure testing, removal of any old tank, the permit, and inspection, all in a written quote after an in-home assessment.
Safety note
If you ever smell gas, hear an unusual popping or whistling from the boiler or tank, or see scorch marks near the burner, leave the house and call FortisBC's emergency line at 1-800-663-9911 from outside before doing anything else. Only a Technical Safety BC licensed gas fitter should open a gas line, relight a pilot, or reconnect venting.
Typically $3,500-$7,500 installed, higher than a storage tank because of the unit cost, venting, and often gas line upsizing.
It fires at a much higher peak rate than a storage tank to heat water instantly, so many older homes need their gas line upsized to supply that demand.
Not always — for modest hot water use, a standard storage tank at lower cost can be the more economical choice; a technician can help weigh the trade-off.
Yes, less mineral scale forms in the compact heat exchanger compared to hard-water regions, which is one of the main things that shortens a tankless unit's life elsewhere.
Yes, generally $75-$200 through the City of Port Coquitlam, included in CANRO's project.
Often yes, though venting usually needs to change since tankless units use different vent material and routing than a standard tank.
