The HeatTrak 20 x 60-inch walkway mat bundled with its GFCI Power Unit is the best starting point for most Canadian homes. Use the HR10-30 stair tread plus the required Power Unit for individual steps, and the 30 x 48-inch stand-alone entrance mat for one broad front-door landing.
Best Heated Snow-Melting Mats in Canada at a Glance
| Configuration | Best for | Current |
|---|---|---|
| HeatTrak 20x60″ with Power Unit | Best overall starter | 2.5A |
| HeatTrak HR10-30 stair mat | Individual steps | 0.7A |
| HeatTrak 30x48″ entrance mat | Stand-alone doorway | 3.2A |
| HeatTrak 30x60″ with Power Unit | Wide walkway | 3.5A |
| HeatTrak 20x30″ with Power Unit | Small landing | 1.3A |
Approximate input power equals current × 120V — roughly 300W, 84W, 384W, 420W and 156W respectively.
The Cold-Weather Limit
HeatTrak states the mat surface reaches about 40°F above ambient and works well down to approximately -22°C, melting up to 2 inches (5cm) of snow per hour. Treat both as manufacturer claims under unspecified conditions. At -30°C ambient, a 22°C rise still leaves the surface below freezing. Use heated mats before or near the beginning of snowfall — not to thaw thick hard ice after an extreme-cold event.
1. HeatTrak 20 x 60-Inch Walkway Mat with Power Unit — Best Overall
Creates a human-width path over a five-foot section. Published 2.5A draw (~300W). Includes the required HR-P GFCI Power Unit — the older mat-only listing looks cheaper but will not operate without it. TUV certified to UL Standard 499 and CSA 22.2 requirements.
Best fit: a front path or route between a door and driveway. Check price on Amazon.ca
2. HeatTrak HR10-30 Stair Mat — Best for Individual Steps
10 x 30 inches, 0.7A per tread. Requires the separate HR-P Power Unit, and all connected mats on that unit must stay within HeatTrak's 13A limit.
Best fit: outdoor steps that repeatedly accumulate snow and ice. Mat: Check price on Amazon.ca · Power Unit: Check price on Amazon.ca
3. HeatTrak 30 x 48-Inch Entrance Mat — Best Stand-Alone Doorway Mat
Stand-alone 120V mat with its own power source, 3.2A draw (~384W), covering 10 square feet. Does not connect into the modular stair-and-walkway chain.
Best fit: a broad, single front-door landing. Check price on Amazon.ca
4. HeatTrak 30 x 60-Inch Walkway Mat with Power Unit — Best Wide Path
50% more width than the 20-inch mat. 3.5A (~420W) — three mats total 10.5A; a fourth exceeds the 13A per-unit limit.
Best fit: a busy entrance route or wider walking aid. Check price on Amazon.ca
5. HeatTrak 20 x 30-Inch Walkway Mat with Power Unit — Best Small Landing
1.3A (~156W), 4.17 square feet. Includes the HR-P Power Unit, establishing the connection point for a future modular chain.
Best fit: a compact landing or the first piece of a planned layout. Check price on Amazon.ca
How to Calculate the Electrical Load
Total current = sum of the current for every connected mat. Keep the total at or below HeatTrak's published 13A maximum per HR-P Power Unit. Never assume a second outdoor receptacle is a separate circuit — a garage heater or holiday lighting on the same breaker can consume most of its capacity. See our garage heater guide for related circuit-planning context.
What Happens During a Power Outage?
The mats stop heating immediately, and meltwater can refreeze. A 720W stair-and-walkway example consumes 0.72kWh per hour — enough to drain a 1kWh-class portable power station quickly. Use our power-station sizing guide before considering battery-powered runtime.
Frequently Asked Questions
Do HeatTrak stair and walkway mats need a separate power unit?
Yes, unless the bundle explicitly says "Mat With Power Unit." The stand-alone entrance mat includes its own power arrangement.
Will a heated snow mat work at -30°C?
Do not assume so. Performance claims apply down to about -22°C, and wind and accumulated ice can make performance worse.
Can I use a heated snow mat on a wooden or composite deck?
Current instructions specifically warn against composite decking — confirm the exact surface in the delivered manual.
Bottom Line
Choose the HeatTrak 20 x 60-inch bundle for the strongest general-purpose starter system, HR10-30 stair mats plus the HR-P Power Unit for individual steps, and the 30 x 48-inch entrance mat for one broad doorway landing. Verify the bundled ASIN, Canadian certification, 13A system limit and drainage path before installation.
