Instructions / Assembly

The table below can be taken as a general guide. Actual requirements will depend on the

floor construction, type of floor coverings, insulation levels etc.

Application W/sq ft

New floors in builds with high levels of insulation 14W/sq ft

Wooden floors 11W/sq ft

Wet areas (showers, bathrooms, stream rooms etc) 14W/sq ft

The heating mat selection will depend on the application.

Note: The UL Listing for this product covers use in wet locations for CANADA only. Wet location

installation in United States shall be in accordance with the National Electric Code, NFPA 70 and

any other applicable jurisdictional code and final acceptance is to be made by the

Authority Having Jurisdiction (AHJ).

Thermal Insulation

The insulation levels of a floor will affect both the performance & running costs of the under tile

heating mat. Using the Heating Mat without thermal insulation can take up to 5 hours to heat

a room whereas a system with thermal insulation takes less than an hour.

If the Warmup heating mat is being installed onto a concrete base it is highly recommended

that a layer of insulation is used prior to installing the heating mat. The thermal insulation re-

flects the heat upwards instead of allowing heat to penetrate into the subfloor, greatly improv-

ing the warm-up times & running costs.

The Warmup insulation boards are fixed to the base using screws and tile adhesive. The

thickness of insulation required will depend on whether it is for floor renovation or a new floor.

Floor coverings

All floor finishes should be installed as per the manufacturers instructions. With radiant heating,

the floor covering is essentially part of the heating system. The most suitable floor coverings are

those with a low thermal resistance, normally referred to as the R-value.

The type and thickness of floor covering materials used with this system must not exceed a

thermal insulation “R” value of 1.
