Quick answer
Installing a gas water heater in Marpole typically costs $1,800 to $3,200 for a standard atmospheric-vent tank, or $2,500 to $4,500 when power-venting or venting changes are needed, plus a City of Vancouver gas permit of $75 to $200. That's a ballpark based on 2026 public market data, not a fixed quote — CANRO's office sets up a short in-home assessment so a certified gas technician can confirm the real cost for your install.

A meaningful share of installation calls in Marpole come from homeowners adding a secondary suite, whether a basement rental unit or a laneway house, both common additions across the neighbourhood given its mix of larger older lots and Vancouver's ongoing push for more secondary housing. Adding a second water heater to serve that new unit independently, rather than stretching one tank across two households, is often the better long-term choice, and it counts as a genuinely new installation with its own gas line, water line, and venting run.
Elsewhere in the neighbourhood, installation calls come from the usual renovation scenarios, finishing a basement or relocating mechanical equipment during a larger remodel of an older home.
| Scenario | Typical range |
|---|---|
| Standard atmospheric-vent tank, installed | $1,800–$3,200 |
| Power-vent tank or venting changes needed | $2,500–$4,500 |
| Gas permit | $75–$200 |
When a Marpole homeowner is adding a basement suite or laneway house, running a genuinely separate hot water system for that unit, rather than tying it into the main house's existing tank, generally avoids the recovery and capacity problems that come from doubling demand on equipment sized for one household. That does mean a second full installation, including its own gas line, water connection, and venting, which is why these projects often land toward the higher end of the cost range compared to a straight single-tank replacement.
The City of Vancouver requires a gas permit and inspection for each installation, and adding a second gas appliance to the property sometimes prompts a closer look at the home's overall gas service capacity.
A tank sized only for the main house, then quietly shared with a new suite, tends to run out of hot water at exactly the wrong moments. A technician planning a genuinely new installation asks about how each unit will actually be used, how many people, how many bathrooms, before recommending a tank size, rather than defaulting to whatever capacity happened to be standard for the property before it was subdivided into more than one living space.
It's worth having this conversation before construction on a new suite or laneway house is too far along, since the gas line, water connection, and venting route for the new tank need to be planned alongside the rest of the mechanical work rather than squeezed in after walls and finishes are already in place.
Safety note
Gas water heater installation involves gas line, water line, and venting work that must be performed by a Technical Safety BC licensed gas fitter. If you smell gas, leave the home immediately and call FortisBC at 1-800-663-9911 from outside.
In most cases yes, a dedicated tank avoids the recovery and demand problems that come from sharing a single tank across two separate households.
A straightforward install into an existing mechanical space typically takes a few hours, while a full new installation for a secondary suite, including gas and venting, takes longer.
Yes, a gas permit through the City of Vancouver is required, along with a final inspection once the installation is complete.
Sometimes; a technician checks the property's total gas capacity when adding a second appliance to confirm the existing service can support both.
It depends on expected occupancy and fixture count, but laneway houses often need a smaller-capacity tank than the main house given typically fewer bathrooms.
Usually a dedicated second tank is the more practical long-term option, since upsizing a shared tank doesn't resolve the underlying issue of two households drawing from one appliance at once.
