Calculators
Three calculators, no defaults we cannot source
Work out whether heating a driveway pays back, what a mat costs to run through a storm, and how many mats a circuit will carry — from your own numbers.
Each one refuses to answer where the data does not support an answer. A blank on these pages is deliberate, and hovering near it you will usually find a note saying which manufacturer or agency does not publish the number.
- Mats vs embedded break-even
- Ten-year cost for portable mats, embedded electric cable, hydronic and a plow service, from your area, your zone and your own quotes. Two of the four have no published price anywhere, so it asks you for those rather than guessing.
- Storm cost calculator
- What one storm and one season cost to melt for a specific mat in a specific place. Where a manufacturer publishes no wattage — which is nearly all of them — it shows a bounded range and says whose arithmetic it is.
- Layout and circuit planner
- How many mats cover your walkway or driveway, what they draw, how many circuits that needs, and the 41 sq ft line where the wiring stops being a plug-in job.
