How to select WarmWire for your room

When selecting the WarmWire electric radiant floor heating wire for your room, remember the following guidelines:

• The floor heat from WarmWire will extend 1.5 inches from the edge of the wire.
• Leave an unheated perimeter of 3 to 6 inches from walls.
• Keep WarmWire 4 to 6 inches from toilet wax rings.
• Heat right into the toekick of cabinets, so you have warm heels and toes.
• Do not place WarmWire in areas that will be covered by fixed cabinets or built-ins.
• WarmWire CANNOT be used in the shower (But SunTouch Mats can!).
• Keep this in mind when deciding on WarmWire Spacing;  Closer Spacing (e.g. 2 Inch Spacing) generates more heat in a shorter time, and requires more wire, while wider spacing (e.g. 3 Inch Spacing) generates less heat and should only be used for very low heat loss areas. We recommend 2 or 2.5 inch spacing.
• You can combine more than one spool on a Thermostat, but total load CANNOT exceed 15 amps on each SunTouch Thermostat Control. Each Spool begins at the thermostat and originates at the Thermostat. Please note that WarmWire Spools do not connect together.
• Buy 3M 90 Spray Adhesive to attach the WarmWire Strap to a concrete sub floor (screws on concrete board or plywood).

Don’t forget to order a WarmWire Strap, Thermostat and other materials to complete your installation. We offer the complete line of WarmWire tools and accessories to make your installation easier.
