Burnaby Heights' narrow character-home basements and older gas lines mean tankless installation usually starts with a careful look at existing infrastructure.

Quick answer
Tankless water heater installation in Burnaby Heights typically requires more upfront assessment than in a newer home, since the neighbourhood's character homes from the 1920s through 1940s often have narrower basements, tighter mechanical spaces, and gas lines that were sized decades ago for a smaller storage tank rather than a tankless unit's higher peak demand. The good news is that removing a bulky storage tank frees up meaningful floor space in these already tight basements, which is one of the more practical reasons Burnaby Heights homeowners choose tankless. A licensed technician needs to assess the existing gas line and find a viable venting path before quoting.

Character homes in Burnaby Heights were built well before tankless water heaters existed, so their gas lines were originally sized for whatever a storage tank water heater and perhaps a furnace required, and often a stove or fireplace too. A tankless unit's peak gas demand is meaningfully higher than a tank's, so the existing line from the meter needs to be checked, and in a number of these older homes it needs to be upsized as part of the tankless conversion, which is worth budgeting for.
On the upside, these basements are often on the smaller side by modern standards, and a wall-mounted tankless unit freeing up the floor space a storage tank used to occupy is a genuinely practical improvement, sometimes opening up enough room for better basement storage or workshop space.
Tankless units need venting routed to an exterior wall, and in a Burnaby Heights basement that can mean navigating around original foundation walls, older framing, or finished basement space added during a past renovation. Finding the most direct, code-compliant path sometimes means the vent run is longer than in a newer home with a more open basement layout, which is a detail your technician will map out during the assessment rather than after installation begins.
| Step | What's checked | Why it matters here |
|---|---|---|
| Gas capacity assessment | Meter size, existing line diameter, total household gas load | Older lines often undersized for tankless peak demand |
| Venting path | Distance to nearest exterior wall, obstructions | Character home basements can have longer or awkward runs |
| Mechanical space prep | Removing old tank, wall mounting location | Frees floor space in a typically tighter basement |
| Commissioning | Ignition, flow rate, temperature at fixtures | Confirms performance before job closeout |
The ballpark for tankless installation is $3,500–$7,500, not a quote, but where a Burnaby Heights job needs gas line upsizing or a longer venting run because of the home's age and layout, that puts the job toward the higher end of that range. Getting a specific on-site assessment before committing to tankless is the only way to know where your particular home falls, since two homes on the same street can differ significantly depending on past renovation history.
It's also worth checking whether asbestos-containing materials are present in older wall or ceiling assemblies before any venting penetration is cut, which your technician should flag as part of the assessment in a home from this era.
Safety note
Gas boiler and water heater work involves combustion, venting, and gas piping that must be handled by a Technical Safety BC licensed gas fitter. CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you ever smell gas near mechanical equipment, leave the home immediately and call FortisBC at 1-800-663-9911 from a safe location.
Possibly, since many character homes here have gas lines sized decades ago for a storage tank rather than tankless peak demand, which a technician assesses before quoting.
Original foundation walls, older framing, or a finished basement from a past renovation can make the path to an exterior wall longer or less direct than in a newer home.
Yes, removing a storage tank and mounting a tankless unit on the wall frees the floor footprint the tank used to occupy, which is often valuable in these smaller basements.
It's worth having your technician check for asbestos-containing materials in older wall or ceiling assemblies before any venting penetration is made.
If your home needs gas line upsizing or a longer venting run because of its age and layout, the job typically lands toward the higher end of the $3,500–$7,500 ballpark range.
