HeatTrak's HR30-60 heated walkway mat costs $27.20 per heated square foot — the highest in our data — and needs three mats per 13 A Power Unit, not five.
The number on the tag: $339.99 for 12.5 sq ft of heated surface
HeatTrak lists the HR30-60 walkway mat at a street price of $339.99, checked on the manufacturer’s own store on 2026-07-25. The mat measures 30 in by 60 in, which we work out to 12.5 sq ft of heated surface (a derived figure — 30 in × 60 in ÷ 144 sq in/sq ft). Divide the price by the coverage and you get $27.20 per heated square foot ($339.99 ÷ 12.5 sq ft), which is the lowest per-square-foot heated price of any mat we track in our product data. That is the headline, and it is worth sitting with for a second: this is HeatTrak’s cheapest square foot, and it still runs $27.20. A homeowner pricing this against embedded electric cable — $8 to $25 per sq ft installed, per WarmlyYours’ own published range for materials and labour in a new pour — will find the portable mat sitting at or above the top of that installed range, before the mat has covered a single day of snow. That comparison only works because embedded systems fold labour into the number and the mat does not; the mat has no installation cost at all, because it is unrolled and plugged in. Both facts are true at once, and neither cancels the other.
Why 30 in is the width that matters
A 30 in by 60 in mat is sized for a single-file walkway — a front-door path, a side gate, the run from a driveway to a porch step — not a two-car apron or a full driveway width. Thirty inches is wide enough for one adult plus a small margin on each side; it is not wide enough for two mats laid side by side to feel like a shovel-width path without a visible seam down the middle. HeatTrak’s connector system — a watertight cord-locking sleeve, prong and socket — is built for exactly that: mats connect end to end or side by side to extend a run, at the cost of adding another 3.5 A to whatever circuit is feeding them. That connectability is the whole reason the amp math below matters, and it is the reason a 30 in mat is a walkway product, not a driveway product, regardless of how many you buy.
3.5 A per mat means three mats per Power Unit, not five
HeatTrak publishes 3.5 A at 120 V for the HR30-60, with no tolerance percentage stated for this model (unlike some of HeatTrak’s other product lines, where amp figures carry a published +/-10%). The mat requires a separate HR-P Power Unit with a built-in 6 mA-trip GFCI, and that Power Unit is rated for up to 13 A of connected mats. Divide 13 A by 3.5 A and you get 3.71 — which rounds down, not up, because a Power Unit rated for 13 A cannot carry a fourth mat’s worth of draw. Three mats pull 10.5 A (3 × 3.5 A), leaving headroom under the 13 A rating. A fourth mat would pull 14 A, which exceeds it. So the real ceiling on one HR-P Power Unit is three HR30-60 mats, not five — a number that only shows up if you do the amp arithmetic against the Power Unit’s rating rather than assume a mat this size scales linearly to whatever the branch circuit itself could carry. Anyone laying out a longer walkway with more than three mats needs a second Power Unit and, in most residential panels, a conversation with an electrician about whether the circuit has capacity for it — we describe the constraint here; we do not walk through hardwiring it, and neither should anyone without a license.
HeatTrak does not publish a total wattage or a watts-per-square-foot figure for the HR30-60, and we are not going to construct one by multiplying 3.5 A by 120 V. That multiplication produces apparent power (VA), not real watts, and presenting it as a wattage would be inventing the exact figure this niche treats as the differentiator between products. Without a published tolerance on the amp figure to carry alongside it, we are not going to offer a bounded VA range here either — we would rather say plainly that HeatTrak has not published total wattage for this mat, and that a UL/ETL cord tag or a written answer from the company is what would settle it. Practically, that also means we cannot translate an electricity rate into a seasonal running cost for this specific mat. In the Upper Midwest zone, residential electricity averaged 15.59 cents/kWh across MN, WI, IA and IL in January 2026 (EIA); in the Northern Plains zone it averaged 12.29 cents/kWh across ND, SD, NE and MT over the same period. Both are real, current numbers — we simply have no published wattage to multiply them against for the HR30-60, and we are not going to guess one to make a cost table look complete.
12.5 sq ft, and why the NEC 426.28 threshold barely applies
One HR30-60 covers 12.5 sq ft. Three mats — the maximum on a single HR-P Power Unit, per the amp math above — cover 37.5 sq ft. That number is worth naming next to NEC 426.28, the section of the National Electrical Code that governs ground-fault protection for fixed outdoor de-icing and snow-melting equipment above a coverage threshold discussed at 41 sq ft. Three connected HR30-60 mats stay under that line at 37.5 sq ft, and in any case the code section targets fixed installations wired into a building’s electrical system — a portable mat plugged into an HR-P Power Unit’s own built-in 6 mA GFCI is a different category of installation, not a fixed one. We are not going to tell a reader whether 426.28 applies to their specific setup; that determination belongs to a licensed electrician looking at the actual layout, not to a specification page. What we can say from the data: this mat’s coverage, even stacked three-wide, sits well below the threshold where that code section becomes the obvious first question.
The melt rate on the box is a marketing claim, not a lab result
HeatTrak publishes a 2 in/hr melt rate for the HR30-60, and a 40 degF surface temperature rise. Both are manufacturer figures, not independent measurements — and every mat on the market publishes a melt-rate claim in the same range, because it comes off the same kind of marketing sheet rather than a shared testing standard. We report the number because it is what HeatTrak states; we do not treat it as a finding, and neither should a reader comparing it against a competitor’s 2 in/hr claim expecting the numbers to mean the two mats perform identically outdoors.
Who should not buy this mat
Narrow steps and stairs are the clearest case. A 30 in by 60 in mat is a flat-run product — it is built to lie on a walkway, not to wrap a tread-and-riser stair geometry, and HeatTrak sells a separate stair-tread line for that job. Anyone shopping “heated walkway mat” because their actual problem is icy porch steps is shopping the wrong product category, regardless of how good the walkway mat’s numbers look.
Beyond stairs: anyone covering more than about 37.5 sq ft on a single circuit should expect to add a second HR-P Power Unit and a second circuit path, which is a real electrician cost this page cannot quote. And anyone comparing this mat’s $27.20-per-sq-ft price against a full-driveway job should look at embedded electric cable’s $8–$25/sq ft installed range instead — at driveway scale, the portable mat’s price per square foot stops being a rounding error and starts being the whole budget.
The two real cons
First: $339.99 for 12.5 sq ft is the highest per-square-foot heated price in our data, and that is before the HR-P Power Unit — priced separately, with no MSRP in our data — is added to the total. Second: HeatTrak has not published a total wattage for this mat, which means we cannot hand a reader a seasonal operating-cost number the way we can for embedded electric cable, where WarmlyYours and ThermoSoft both publish watts per square foot. That gap is a real limitation of the product’s public documentation, not a rounding choice we made.
Our layout planner works out mat-and-Power-Unit combinations against a given walkway footprint from the published amp figures above; our break-even tool compares the mat’s actual purchase price against embedded cable’s published installed-cost range over a multi-year horizon, using the visitor’s own snow zone.
