Heated driveways and snow-melting mats in the Appalachian Highlands (WV, western VA/NC, western PA, eastern TN)

Snowfall normals, electricity rates and melt-capability figures for the Appalachian Highlands (WV, western VA/NC, western PA, eastern TN), computed from NOAA and EIA data.

This page is data only — the written analysis has not been through editorial review yet, so it is marked noindex until it has.

Marginal

A 5 in day clears in 2.5 h, but normal snowfall means about 42 h of running a year.

  • The melt rate is the manufacturer's claim, not a measurement. SnowWatt has not operated this product. Every portable mat on the market quotes the same 2 in/hr, which makes it a marketing constant rather than a differentiator.
  • Clear time assumes continuous running on a mat that starts clear. It is the time to melt that much accumulation, not a storm-duration model, and it does not account for drifting, refreeze, or snow arriving while the mat works.
  • The design day is a 30-year normal, not a forecast. 83.5 in a year at Elkins-Randolph Co AP, WV (NOAA GHCN-Daily, 1991-2020), the largest daily threshold crossed at least once a year. Your worst day will be worse.

  • HeatTrak does not publish a wattage for this product. The figure above is SnowWatt's own arithmetic — 120 V × 2.5 A — and it is apparent power in VA, not a measured wattage. HeatTrak states no tolerance on this figure, which is not the same as a tolerance of zero — treat the cost below as an order of magnitude, not a quote. Treat it as an upper bound on real power, and see the methodology page for why we will not print it as watts.
  • Hours come from the melt gauge above: 2.5 h to clear the design-day accumulation, and about 42 h a year to keep pace with normal snowfall. Both assume continuous running and no idling, standby or preheat — so the season figure is a floor, not a forecast.

Elkins averages 83.5 in a year across 26.3 days over an inch — snowbelt-grade frequency on cheap electricity (14.77 cents in WV), and almost no competing content. Steep driveways make the stair-and-walkway products more relevant here than driveway systems.
