Heated Floor Installation
ComfortTile Electric Radiant Floor Heating
To install a
heated floor in your bathroom, follow the procedure
(For more detailed
instructions, please refer to the product installation
Measure the room and draw a
sketch to help you calculate which floor
heating package you will need. Then sketch in
the position of the ComfortTile
floor heating mat.
Mark the positioning of the
toilet before you remove it. (Use a
marker to draw around the base.) This helps you
avoid placing the toilet on top of the
floor heating mat, and allows you to position
the ComfortTile cable accordingly so you avoid
piercing it with the toilet screws.
Cut a channel approximately 10
mm (¼-½-inch) deep and about an inch
wide in the wall and about 3½ feet out into
the subfloor. (This groove runs from
the wall-mounted thermostat down to the heat
cable in the floor.)
Glue the flex pipe for the
sensor into this channel and seal the end
of the pipe with a piece of tape.
Clean the floor thoroughly,
removing all dirt and soap residue, then
lay out the self-adhesive cable mat. The floor
surface must be primed if you are not
laying the mat on existing tiles.
Clip through the flexible
netting to allow placement of the heat
cable over or around objects as needed.
Make sure that you only cut the
netting and do not cut or damage the floor
When you reach corners or
objects that require custom fitting, turn
floor heating mat (after the
netting has been cut) and use the self-adhesive
back to position it as required. The
self-adhesive backing can withstand 10-20
adjustments, so you can move the mat several
times until you are satisfied with the
Depending on the new floor
surface you are installing, after you have
positioned the ComfortTile cable mat, you can
encapsulate it using a self-leveling
screed or cover it with a thin layer of Quick
Level or thin-set (tile adhesive). Now
you are ready to install the finish
surface of your new radiant heated floor.
