Expected floor temperature
Heating performance is never guaranteed. The floor temperature attainable is dependent on
how well the floor is insulated, the temperature of the floor before start up, and the overall
thermal drain of the floor mass. Insulation is required for best performance. Refer to Phase 4
for important design considerations.
Important Safety Information
This is a safety-alert symbol. The safety alert symbol is shown alone or used with
a signal word (DANGER, WARNING, or CAUTION), a pictorial and/or a safety
message to identify hazards.
When you see this symbol alone or with a signal word on your equipment or in
this Manual, be alert to the potential for death or serious personal injury.
This pictorial alerts you to electricity, electrocution, and shock hazards.
This symbol identifies hazards which, if not avoided, could result in death
or serious injury.
This symbol identifies hazards which, if not avoided, could result in minor
or moderate injury.
This symbol identifies practices, actions, or failure to act which could result
in property damage or damage to the equipment.

These are the three most common installa tions:
1. Wood framing:
With the mat installed on a well-insulated wood subfloor, and thin-set mortar
and tile on top, most floors can be heated up to 20°F warmer than they would otherwise be.
2. Insulated concrete slab:
With the mat installed on an insulated concrete slab, and thin-set
mortar and tile on top, most floors can be heated up to perhaps 15°F warmer than they
would otherwise be.
3. Uninsulated concrete slab:
With the mat installed on an uninsulated concrete slab, and
thin-set mortar and tile on top, most floors can be heated up to perhaps 10°–15°F warmer
than they would otherwise be.
Please consult a designer or the factory if questions remain about the surface tempera ture
that can be expected from the cables in any particular construction.
