Slab Heating Cable 120V, 252 ft., 12.5A
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.
