Slab Heating Cable 240V, 402 ft., 10.0A
How Much Cable Will I Need?
The amount of cable you'll need depends on the heat output and amount of heating coverage you want, both of which are impacted by the spacing of the heating cable.
The recommended spacing for Slab Heating Cables is 3", which will provide a heat output of over 20-watts per sq. ft.
You can use our quote tool to get a rough estimate of the amount of cable you'll need for a project.

Our electric radiant floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce much less EMF than common household appliances like your TV or vacuum cleaner. The EPRI (Electric Power Research Institute) tests all electrical devices and publishes the data. Many common household appliances are tested at a distance of 6 inches. The test results indicate that on average, the EMF emitted for the following appliances, measured in Milligauss (mG) units, is:
Vacuum Cleaner: 300 mG
Microwave: 200 mG
Portable Heater: 100 mG
Dishwasher: 20 mG
Washing Machine: 20 mG
WarmlyYours TempZone™ (Twin): 1.8 mG
WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the electric radiant floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.
