Install Steps

Step 1:

Plan your layout and determine the cable direction. Measure

about 3" in. inches from the wall, and place strap parallel to

the wall. Under toe kick spaces, install the strap 1.5"in. inches

to 2" in. inches away from the vanity.


Step 2:

Cut the strap to length for each side of area

to be heated. 




Step 3:

Secure the strap to the subfloor using double-sided

tape, glue, or fasteners.





Step 4:

Fill in each section back and forth with cable,

spacing the wire 2.5" or 3" in. inches

apart. For additional areas, cut and attach the

straps accordingly and begin weaving the 

wire into that area.




If cables are running greater than 3' or 4'ft. feet across a room, be sure to add another

strap to thread through in the center of the area to be heated.

Why Helps

WarmWire = Zero EMF

Electromagnetic fields (EMF) are generated by all electrical devices, and the possible dangers of exposure to EMF are still the subject of debate and scientific research. Out of concern for their customers' safety, SunTouch created the first EMF-canceling electric radiant floor heating system in 1993, and to this day they only manufacture and sell floor heating systems that use their patented EMF-canceling design. We provide this EMF information because it is important to some people, not to frighten you or exaggerate any risk like others do. We simply aim to inform you and leave the choice up to you after explaining what we know. Read More Here.
