Warm Floors, Built-In Safety: The 100 sq ft GFCI Radiant Heat Kit

Bring radiant warmth to cold tile floors with this complete 120V electric radiant floor heating kit. It pairs 400ft of ultra-thin (1/8") HeatTech heating cable with a Honeywell 7-day programmable thermostat featuring a built-in 5mA GFCI — the safety standard required for bathrooms, kitchens, and other moisture-prone rooms.

The loose-cable design gives you flexible layout options for rooms of any shape or size: 65 sq ft of coverage at tight 2" spacing, 100 sq ft at the recommended 3" spacing, or up to 135 sq ft at 4" spacing. At 1,200 watts of peak power and zero EMF, it delivers even, efficient warmth without electromagnetic interference.

What's Included:

• 400ft HeatTech electric floor heating cable (120V, 10A, 1200W)
• Honeywell TH115-AF-GA GFCI thermostat, 7-day programmable
• Floor sensor with 15ft leads
• Two 25ft rolls of cable installation guides
• Continuity monitor ("Screamer") — alerts you immediately if the cable is damaged during installation, before you lay flooring over it
• Full installation manual

Whether you're renovating a bathroom, warming a kitchen floor, or heating an entryway, this kit combines coverage flexibility with built-in ground-fault protection and pre-install damage detection.
