Electric radiant floor heat, also
known as electric under floor
heating, can be installed
throughout the home or
zoned to heat a single room.
The heat source is a specially
designed, insulated copper
cable that reaches an internal
temperature of 115 degrees.
The cable is sold either on
rolls for free form installation,
or woven into mats of varying
widths and lengths for under
floor or under carpet
installation.

Electric Radiant Floor Heat
Free form cables are used under tile or hardwood floors and
are no thicker than the layer of tile adhesive or scree
applied to the sub floor adding only 1/16" to 1/8" to the
floor height.
Insulated cables use anywhere from 8 to 15 watts of
electricity per square foot of floor area depending on how
close the wire loops are spaced.
Mesh mats are also used for underfloor tile and hardwood
heating. The mesh can be cut between the cables to the far
seam and rotated 180 degrees for the return run or to fit an
irregular floor plan.
The loops use approximately 12 watts per square foot and
are spaced closer together than free form cables.
Heated underfloor pads are installed under laminate,
floating wood or engineered wood floors. They also work
with interlocking tile systems.
The 1/8" thick pads are rolled out over the sub-floor (no
cement required), and seamed together with duct tape.
Under carpet electric heating mats are available in rolls for
installation under wall to wall carpeting, or in panels sized
to fit under area rugs and runners.

No matter what type of heating system you're investigating, your first consideration
should always be cost and availability of fuel. In the case of electricity, it's readily
available just about anywhere, but the cost per kWh (kilowatt hour) varies widely
from region to region.
Here's an easy way to estimate the cost of heating with electric mats where you live.
Multiply the square footage of the room you plan to heat x .012 (the average number
of kilowatts an electric mat consumes per sq. ft.) x cost per kWh (check your bill) =
your cost per hour to heat the room.
For example, this how the formula would look for a homeowner paying $0.10 kWh to
heat 150 square feet: 150 x .012 x .10 = .18, or 18 cents per hour.
Manufacturers of electric radiant heating systems are introducing new and innovative
products on a regular basis. Many, like the examples on this page, can be installed by
anyone with average dyi skills up to the point where a licensed electrician is required
to make the final connection.
