Warm Tiles is a network of cables placed in the mortar
just below your tile, marble or slate floors to remove the
The Warm Tiles system is designed for 120V or 240V
applications in North America. The current draw of the
largest size cable is 10.7 amps. The system can be installed
to dissipate either 12 Watts per square foot (when using the
Standard 3" spacing) or 16 Watts per square foot (when using
the Alternating 3"/1.5") spacing.
There is a fifteen (15) year limited warranty on our Warm
Tiles cables. Warranty details are provided in the

Warm Tiles Warranty
Warm Tiles is designed for marble, ceramic, concrete,
tile, slate, paver (brick, stone, etc.),laminate and
engineered wood* type floors. It is NOT designed for wood,
carpet, linoleum, or vinyl tile floors. Warm Tiles cable
MUST be embedded in "cementitious material" (e.g., mortar).
*For use under engineered, floating wood floors only. Not
approved for nail down installations.
From the time the cables are turned ON it usually takes
about half an hour to 2 hours to warm the floor, depending
upon floor material and thickness.
The surface temperature of the floor depends upon several
variables: the spacing between adjacent runs of cable, the
depth from the cable to the tiles' surface, the total
thermal mass of the floor, and the temperatures of the room
and area beneath the floor. For this reason, the temperature
range will vary from installation to installation.
Generally, Warm Tiles cables will warm a floor to a maximum
of about 90 degrees F.
Warm Tiles is not designed as a primary heat source for
We recommend that the heating cable be the ONLY load on
the electric circuit supplying power to the cable. Always
check with your local electrical inspection agency prior to
installing Warm Tiles.
Warm Tiles is simple to install. Any skilled
Do-It-Yourselfer with adequate knowledge of flooring and
electrical wiring can install your own floor warming system.
Just read the comprehensive installation instructions found
in your floor warming kit and follow the steps.
You will need to measure the area of the floor that you
intend to warm in square feet. When figuring square footage,
do not include areas under toilets, vanities, plumbing
fixtures, or inaccessible areas. Allow at least 1 inch from
toilets or other fixtures. Measurements should be as
accurate as possible. Once you have determined the square
footage to be warmed, you can select the appropriate size
Warm Tiles cable system.
Note: If you are considering installing
Warm Tiles under a shower area, check local electrical codes
to see if this is allowed.
Yes. A resistance reading can be taken with an ohmmeter.
Insulation resistance can be verified with a megger. Do Not
energize the cables prior to installation.
Complete, detailed installation instructions are provided
with every cable. Plastic strapping, provided with the
cable, is stapled to the floor. The cable easily snaps into
the strapping and is "laced" over the floor area to be
heated. A cementitious mortar is then applied over the
The length of heated cable CANNOT be altered. Cold leads,
however, can be cut to desired length.
Placing insulation under your floor is not imperative;
however, it will increase the operating efficiency of your
Warm Tiles system by minimizing heat loss.
No. The electrical codes (NEC in the US and CEC in
Canada) do not allow heating cables to be installed behind
A thermostat is recommended for all Warm Tiles
installations. Easy Heat offers both 120V and 240V
thermostats in two distinct models. The FTS Series
thermostats offer comfort level programming options as well
as a simple off position selector switch. The ET Series
thermostat offers a simple on/off switch along with a
temperature adjustment toggle and accept button. All Warm
Tiles Thermostats have integral ground fault protection.*Per
U.S. National Electrical code - installation in a bathroom
requires that this device be installed on a circuit
protected by a separate Ground Fault Circuit Interrupter (GFCI).
The thermostat can be set to various levels to maintain a
constant floor temperature. You will quickly become familiar
with your own comfort zone and its corresponding setting on
Generally, Warm Tiles cables can be installed in tiled
shower areas by installing the cables in a scratch coat
using the standard method noted in the installation
instructions. Then, a waterproofing membrane is installed
over the cables to ensure that all water from the shower is
directed to the drain and does not come in contact with the
If the cable is cut or penetrated, the flow of current
will be directed to the grounding braid surrounding the
cable, thereby causing the ground fault protection to trip,
which removes power from the cable. Depending on the type
and severity of the damage, there is a possibility that a
repair may be necessary.
Warm Tiles systems are very cost effective to operate.
When used in conjunction with a setback thermostat,
operating costs are about 1 cent per square foot of heated
area per day. Note that the heat from a warm floor will
disperse throughout the home and thereby offset home heating
Well, it's thought that the early Greeks were the first
to develop such a system but it was the Romans who put it to
practical use with their hypocaust system. In many Roman
buildings, mosaic tile floors were supported by columns
below, which created air spaces, or ducts. At a site central
to all the rooms to be heated, charcoal, brushwood and in
Britain, coal were burned and the hot gases traveled beneath
the floors, warming them in the process. The hypocaust
system disappeared with the decline of the Roman Empire and
"central heating" was not reintroduced until some 1,500
years later. The Romans were not alone in their development
however, the ancient Koreans had their own system of floor
heating. With temperatures in winter dropping to as far as
20 degrees below zero there was obviously a great deal to be
gained by developing a system to keep warm. Since the 5th
century they have built their homes with an "ondol" (which
translates as "warm stone") floor. While similar to the
Roman hypocaust system the ondol relies on warm water. This
system is used in Korea to this day!
Yes, but the Warm Tiles cable must not be more than 3/4"
from the surface of the floor.
The cable MUST NOT touch, cross, or overlap itself at any
point. This would cause the cable to overheat and require
