Interior New England is the second most expensive of the eleven US zones on this site to run a heated driveway, and the most expensive one where a portable mat is still arguably in scope. Burlington, VT averages 81.2 in of snow a year (NOAA 1991–2020 normal, station USW00014742), and the zone’s residential electricity averages 27.88 cents/kWh (EIA, January 2026, unweighted mean of VT, NH, ME and MA). Only the Sierra–Cascades zone costs more to run, and our melt computation says not to attempt a mat there at all. Here the snow is survivable and the meter is the problem.

What marginal means on a 5-inch design day

Our melt-capability verdict for this zone is marginal. The design day — the deepest daily-snowfall threshold Burlington crosses at least once a year — is 5 in, recorded on 3.6 days a year. At the 2 in/hr melt rate every portable mat on the market markets itself with, clearing that takes 2.5 hours of continuous running (5 ÷ 2, our arithmetic on the vendors’ claim, not a measurement anyone published). Across a normal winter, 81.2 in at the same claimed rate is 40.6 hours of running.

Marginal is the verdict between “the arithmetic clears comfortably” and “do not try”: 2.5 hours is past the 2-hour ceiling we set for a keeps-up verdict, and 40.6 hours a year is well inside the 60-hour ceiling that would make it overwhelmed. In practice that means the equipment can do the job on paper and has no margin left for a storm that arrives overnight, unattended, on top of what fell yesterday.

One detail the zone average hides: Concord, NH records less total snow than Burlington (61.4 in) but slightly more days at or above 5 in — 3.7 against Burlington’s 3.6. Deep days are not a function of the annual total, which is why the design day and the seasonal burden are computed separately rather than derived from one number.

Appalachia gets the same snow for a little over half the bill

The clearest way to see that electricity is the deciding variable here is to hold the snow constant. Our Appalachian Highlands zone averages 83.5 in a year at Elkins, WV — 2.8% more snow than Burlington — and computes to the same 5 in design day, the same 2.5-hour clear time, and a near-identical 41.75-hour seasonal burden. Its electricity averages 15.52 cents/kWh.

Run the same equipment through both. Embedded electric snow-melting products in our records publish 41–50.09 W/sq ft (ThermoSoft NeverFreeze at 41–48, WarmlyYours at 50–50.09), and for the 400 sq ft two-car driveway WarmlyYours uses in its own worked example that is 16.4–20.04 kW of connected load — derived by multiplying published wattage density by published area, not a manufacturer total.

Same job, more snow in West Virginia, and about 56% of the operating cost. Nothing about the equipment or the weather explains that gap; it is entirely the rate.

Inside this zone, the rate moves 34% across a state line

The 27.88-cent zone figure is an unweighted mean, and the states inside it are far apart: Vermont at 23.29 cents, New Hampshire at 26.32, Maine at 30.73 and Massachusetts at 31.16 (EIA, January 2026). Vermont to Massachusetts is a 34% spread on identical hardware.

For the same 400 sq ft system across the same 40.6-hour season, that works out to roughly $155–$189 in Vermont and $207–$253 in Massachusetts, with Maine at $205–$250. A single 5 in design-day storm runs 41–50.09 kWh, or about $11.43–$13.97 at the zone average and $12.60–$15.39 at Maine’s rate.

WarmlyYours publishes its own runtime cross-check for that 400 sq ft system — 50–120 hours a season over 10–20 storms — which at this zone’s rate would be $229–$670. That band sits above our 40.6-hour figure, and we show both rather than splitting the difference: theirs counts storms across a general market, ours divides this station’s published snowfall by the melt-rate claim. Neither is a bill. Your own rate and your own area are what our storm cost tool runs on.

Mats are priced per square foot of mat, not per square foot of driveway

A HeatTrak HR20-60 covers 8.33 sq ft and lists at $229.99 — $27.61 per square foot heated. Five of them plus the required HR-P power unit ($39.99) is $1,189.94 for 41.65 sq ft, or $28.57 per square foot heated, drawing 12.5 A of the power unit’s 13 A capacity. Our layout planner assembles those combinations from published dimensions and circuit limits.

Set that against embedded cable at $8–$25 per square foot installed, published by WarmlyYours for its own product category and dated 2026-07-02 — $3,200–$10,000 for that 400 sq ft driveway. Per square foot of heated surface, mats are the more expensive product by roughly 3x at the manufacturer’s low end, and they cover only the strip you buy. That is the trade this zone’s readers usually get backwards: mats are cheap to acquire and expensive per unit area, and embedded systems are the reverse.

The other half of the mat problem is that we cannot cost one. HeatTrak publishes 2.5 A at 120 V for the HR20-60 and states no tolerance on its residential figures — its PRO sheets carry ±10%, the residential pages carry nothing, and no stated tolerance is not the same as ±0%. Multiplying gives 300 VA of apparent power, which is not a wattage and cannot be read as one. No portable-mat manufacturer publishes total watts, so in the zone where operating cost decides the purchase, the mat branch is the one branch with no operating figure at all.

Who should not buy here, and the two blanks we will not fill

Anyone in this zone whose plan is to cover a two-car driveway with portable mats should read the paragraph above twice: the product that would need the tightest running-cost estimate is the one that publishes no wattage, and at Maine or Massachusetts rates that blank is worth real money.

Anyone whose snow problem is one or two storms a year is also in the wrong place. This zone records 22.9 days a year at or above 1 in across a 30-week season — it is a repeat-event problem, and the arithmetic on this page assumes that shape.

Two things we do not have. Portable-mat wattage, above — a written figure from HeatTrak or a UL/ETL cord tag would settle it, and until one exists we publish a bounded VA range and nothing firmer. And a seasonal plow-contract price, which is the do-nothing baseline every break-even calculation needs: the only publishers of one are lead-generation marketplaces quoting their own unaudited job data, and both were unreadable at source on 2026-07-25. Our break-even calculator therefore asks for your own plow quote rather than inventing the number that decides the answer.

One more caution about the figures above. Nothing in our cost model replaces a mat inside the comparison horizon, because no manufacturer publishes a service life — HeatTrak’s residential warranty is 2 years, which is a liability term and not a life expectancy. That assumption is the most generous reading available to mats, and it is worth knowing which way the thumb is on the scale.
