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 spacing of the heating elements is dictated by how the cable is installed and WarmlyYours offers two different installation methods: with Fixing Strips or with our Prodeso Membrane.
Fixing Strips
An economical option, requires more work than the membrane.
Ideal spacing for installing TempZone 3.7-watt Cable:
- 3" (14.8-watts per sq. ft.)
Other spacing options:
- 4" (11.1-watts per sq. ft.)
- 5" (8.88-watts per sq. ft.)
Prodeso Membrane
Costlier than strips, speeds up installation and provides uncoupling benefits
Ideal spacing for installing TempZone 3.7-watt Cable:
- 3.75" (11.84-watts per sq. ft.)
Other spacing options:
- 5" (8.88-watts per sq. ft.)

Description
The TempZone Floor Heating Ruler Cable is the first electric radiant heating cable to feature easy-to-read hash marks at every half-inch, inch, and foot increment. This innovative design, along with a free SmartPlan installation plan from WarmlyYours, ensures the installer is using the proper amount of cable while they’re laying it out along with making sure the heating elements are in the proper location. This will help guarantee a smooth installation of the floor heating system and even heating coverage for the end user.
The TempZone Floor Heating Ruler Cable is meant to be embedded in thinset or self-leveling compound beneath a wide range of floor coverings like tile, marble, stone, LVT, and more. The cable provides 3.7 watts per linear foot (9-15 watts per sq. ft. depending on spacing).
This cable is also very safe with a UL listing for use in both the US and Canada and ultra-low EMF levels due to a 100% Mylar shield around the ground wire in the cable. The TempZone Floor Heating Ruler Cable is also more durable than many other comparable cables due to its crush resistant ETFE (fluoropolymer) core insulation and high-temperature PVC jacket. Additionally, the elements of the cable are constructed in such a way that the cable has exceptional flexibility in nearly all directions.
The TempZone Floor Heating Ruler Cable can be installed in two different ways: with fixing strips or with an uncoupling membrane. The fixing strips are complimentary and are the most economical but also labor intensive option for installation. Using an uncoupling membrane is more costly but also provides other benefits like speed of installation, crack isolation, and the possibility of waterproofing the installation with accessories.
The TempZone Floor Heating Ruler Cable is covered by our industry-leading 25-year No Nonsense™ Warranty.
