Quick answer
A tankless gas water heater in an Edmonds home replaces a storage tank with an on-demand unit, and since so many original tanks in this post-war neighbourhood are reaching end of life around the same time, tankless is a common upgrade path homeowners consider at replacement. Older Edmonds homes typically need the gas line checked and often upsized to handle a tankless unit's higher peak draw.

Edmonds' post-war housing stock means a large number of original or first-replacement storage tanks are now reaching the end of their service life within a similar window, and when a homeowner faces a water heater replacement anyway, tankless is a natural option to evaluate rather than simply installing another tank of the same type. The appeal is usually continuous hot water and freeing up floor space in an older, often compact mechanical room or crawlspace.
CANRO's Burnaby base is close to Edmonds, which is useful both for the initial assessment visit and for any follow-up service after installation.
Homeowners planning a basement renovation are also a common source of tankless inquiries in Edmonds, since reclaiming the floor space a storage tank occupies fits naturally into a project that's already reworking the layout of that level, and coordinating the water heater swap with the broader renovation timeline avoids opening up finished walls twice.
| Factor | Why It Matters |
|---|---|
| Simultaneous fixture count | Determines the flow rate the unit must sustain |
| Existing gas line size | Older post-war homes often have undersized original piping |
| Venting distance to exterior wall | Affects vent sizing and routing |
| Water hardness | Metro Vancouver's soft reservoir water limits scale buildup |
Older Edmonds homes frequently have gas piping sized decades ago for a single furnace and water heater, and a tankless unit's higher peak draw usually means that line needs to be checked and, in many cases, upsized as part of the installation.
We check total household gas demand rather than looking at the water heater line in isolation, since a home that has added a gas range or a fireplace insert since original construction may already be closer to its service capacity than the homeowner realizes.
A typical Edmonds tankless installation includes gas line assessment and any needed upsizing, running new venting to an exterior wall with proper clearances, and commissioning the unit with a combustion test and a gas pressure check under full flow. On a compact original mechanical room, we also confirm there's adequate clearance for the wall-mounted unit and any required air intake.
Installation runs in a ballpark of $3,500 to $7,500, with older homes needing gas line upsizing typically landing toward the higher end of that range. This is a ballpark, not a quote, until a technician has assessed your specific home's existing gas and venting setup.
Safety note
If you ever smell gas, hear a hissing sound near a gas line or appliance, or notice soot, a persistent headache, or a yellow or flickering burner flame near your boiler or water heater, leave the house immediately and call FortisBC at 1-800-663-9911 from somewhere safe. Gas piping, venting, and combustion appliances must only be installed or serviced by a Technical Safety BC licensed gas fitter.
It's worth considering, since you're already facing a replacement. Tankless offers continuous hot water and frees up space in an often compact original mechanical room, though it costs more up front than a conventional tank.
Often yes, since these homes typically have gas piping sized decades ago for a single furnace and water heater. We assess the existing line during the initial visit and include any upsizing in the quote.

The region's soft reservoir water causes less mineral scale than harder water elsewhere, though we still recommend an annual descaling flush to protect the heat exchanger long term.
