Quick answer
As a 2026 ballpark based on public market data, not a firm quote, gas-boiler-fed radiant floor heating in Burnaby generally runs $7 to $17 per square foot for the PEX loop and installation, with a full whole-house system including the boiler landing between $12,000 and $43,000. The wide spread reflects whether this is new construction with open subfloor access or a retrofit into an existing finished home, and how many zones the layout requires. CANRO's certified technicians scope your specific floor plan and heating load before quoting an exact price.

The single biggest factor in radiant floor pricing is whether the PEX tubing goes into an open subfloor during new construction or a major renovation, or has to be retrofitted into an existing finished home. New construction and full renovations, common in Burnaby's newer infill builds near Brentwood and Metrotown, let the tubing be laid directly into the subfloor or a thin-slab pour before flooring goes down, which keeps per-square-foot costs toward the lower end of the range. Retrofitting radiant heat into an existing character home near Capitol Hill or Burnaby Heights, where floors and finishes are already in place, usually means either a low-profile panel system installed above the existing subfloor or opening up ceilings below to run tubing from underneath, both of which add labour and push costs higher.
The boiler sizing itself also depends on total floor area and how well the home is insulated. A well-insulated newer build needs less boiler output per square foot of radiant floor than an older, leakier character home, which is one more reason a walkthrough matters more than a square-footage calculator alone.
| Scope | Ballpark range | Notes |
|---|---|---|
| Radiant floor loop, typical range per sq ft | $7–$17/sq ft | New construction with open subfloor access sits lower; a retrofit into finished space sits higher |
| Whole-house system including gas boiler | $12,000–$43,000 | Depends on home size, zones and boiler output |
| Boiler portion alone, if sized for radiant load | $6,500–$14,000+ | Same boiler install ballpark as a standard boiler |
Radiant floor heat pairs naturally with Burnaby's damp coastal climate, since it keeps floors consistently warm rather than cycling forced air, which some homeowners find more comfortable through a long, wet winter. It's also a common addition in below-grade suites and laneway homes, increasingly popular across Burnaby, where floor-level comfort matters more than in an upper-floor room. The soft reservoir water supply doesn't directly affect the radiant loop itself since it's a closed system, but it does mean less scale buildup in the boiler feeding that loop over the system's lifespan.
PEX tubing embedded in a slab or subfloor is built to last decades and rarely needs full replacement; most issues trace back to the boiler, circulator pump, manifold valves or a zone control rather than the tubing itself, and those are repaired individually rather than tearing up flooring. A full system replacement is really only on the table if the original tubing was damaged during a later renovation or if you're doing major structural work anyway and it makes sense to redesign the zone layout at the same time.
Safety note
Radiant floor systems fed by a gas boiler involve combustion, venting and pressurized piping, and installation must be done by a Technical Safety BC licensed gas fitter; CANRO holds gas licence LGA0043870 and boiler licence LBP0046450. If you ever smell gas near the boiler, leave the home and call FortisBC at 1-800-663-9911 from a safe distance.
As a 2026 ballpark, $7 to $17 per square foot depending on whether it's new construction with open subfloor access or a retrofit into a finished home.
Typically $12,000 to $43,000 as a ballpark, depending on home size, number of zones and the boiler output required.
Yes, retrofitting into a home with finished floors and ceilings generally costs more per square foot than laying tubing during new construction or a major renovation.
Yes, a single-room or single-zone retrofit is common and less costly than a whole-house system, though it still needs a boiler with enough capacity.
Rarely, since PEX tubing embedded in a slab or subfloor typically lasts decades; most radiant system issues trace back to the boiler, pump or valves instead.
Often yes, since it suits smaller footprints well and keeps floor-level spaces comfortable, which matters in a compact laneway or basement suite layout.
