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.)
