120V vs 240V TempZone Ruler Cable: The Professional's Complete Selection & Superiority Guide

The industry's first ruler-marked heating cable with game-changing features that set new professional standards

What's the Difference Between 120V and 240V Floor Heating Cable?

Frequently Asked Questions

Q: Can I use 120V cable on a 240V circuit?

A: No. Always match cable voltage to circuit voltage. Using incorrect voltage will damage the cable and void warranty.

Q: Which voltage is more energy efficient?

A: 240V is more efficient for larger areas due to lower amperage draw and reduced line losses.

Q: Do I need a separate GFCI with TempZone Ruler Cable?

A: No. All WarmlyYours controls have built-in GFCI protection, saving installation time and cost.

Q: What makes the ruler markings so important?

A: Precise spacing is critical for even heat distribution. Ruler markings eliminate measuring errors and ensure perfect 3", 4", or 5" spacing every time.

Q: Can homeowners buy TempZone Ruler Cable directly?

A: No. TempZone Ruler Cable is exclusively available to trade professionals, contractors, and installers. It's not sold on Amazon, big box stores, or directly to homeowners, ensuring professional control and protected margins.

Q: Can I achieve 5" spacing on concrete slabs?

A: No. 5" spacing (8.9W/sq. ft.) is only for comfort heating on wood subfloors in warmer climates. Concrete slabs require 3" or 4" spacing due to thermal mass.
