Installation On A Concrete Slab
When installing on a concrete slab we recommend using some type of insulation such as Cerazorb to avoid heat loss through the concrete. Another option is to space the wires at 2" apart rather than 3". Please keep in mind that if you installed your floor warming system on a concrete slab without using insulation it will take longer for the floor to warm up since the concrete needs to be warmed up first. Leave the system on longer and increase the temperature on the thermostat.
