Wiring configurations
Before installing the heaters, refer to the sizing guide on page 18 of this booklet to ensure
you have the proper number and size of heaters for the area you wish to heat. The sizing
guide will also give you the perimeter and heating wire spacing required for your particular
room size.
While the installation instructions only make provision for the wiring to be installed in a set
configuration, there are many instances where departure from this configuration may be
desirable. Below are a few drawings illustrating the versatility of the Warmup® Undertile™
Heating System.
In each of the examples, the floor space is heated using different wire configurations to suit
the particular layout of the room. It should be noted that while the sizing chart provided in
this booklet is a useful guide to heater layout, it may be necessary to slightly alter the heating
wire spacing to suit your particular installation. However, at no time should the spacing between
the wires be less than 2” or greater than 4”.
