Installing Heated Wood Flooring

Installing heated hardwood flooring can be done by the homeowners themselves or by a professional installer. WarmlyYours provides free design help to create a plan to install your heated wood floors, and, in most instances, orders are shipped the same day they are received, so you'll be able to appreciate the advantages of radiant heating systems sooner than you thought possible.

When choosing a system for heated hardwood floors there are a few considerations that will help make the project a success. Selecting wood flooring that will be the most compatible with radiant heating will help ensure many years of comfortable enjoyment of your home.

Electric radiant heating can be installed quickly and easily under any hardwood floor. For hardwood floors, WarmlyYours recommends that our TempZone™ Floor Heating Cable is installed with fixing strips. The instructions for installation are straightforward, but there is also 24/7 technical support available if you need more assistance. Thin wood sleepers are laid down on the subfloor to create channels for laying out the heating cable and fixing strips, which are then embedded in self-leveling cement. The wood flooring is then nailed into the sleepers to complete the job.

How Warm Are Heated Floor Systems?

Most wood flooring manufacturers recommend that the heated wood floor temperature be maintained between 80 to 85 degrees. This provides a warmer surface than an unheated floor, even in a well-heated house, but it is not so warm that it would feel hot to the touch.

The warmth of the floor is also dependent on the characteristics of the selected wood flooring. A thinner floor will typically be a few degrees warmer than a floor with thicker boards. Some wood species offer slightly better performance for radiant heating than others. The way that the boards are sawn can also make a difference. Quarter sawn boards are more expensive, but are more stable and less prone to swelling and shrinkage due to humidity changes. It has also been noted that darker woods will be less likely to show gaps and cracks. All of these factors should be considered in choosing the hardwood floor for your home.

Radiant heat has higher levels of energy efficiency than most traditional systems.

Frequently Asked Questions

The TempZone™ Flex Rolls, Easy Mats and Shower Mats are designed to deliver 15 watts per square foot (maximum allowed by the National Electrical Code), with the heating element positioned 3” apart on a serpentine loop attached to a fiber mesh. The TempZone™ Cable yields between 8-12 watts per square foot, variable, based on the cable spacing. TempZone™ Custom Mats are made to order, so the spacing of the heating element throughout the mat varies according to each specific design. The TempZone™ Custom Mats can yield from 12 to 15 watts per square foot.

No. Never cut the heating cable. The floor heating cable is designed with a very specific resistance in order to consistently maintain heating at the chosen wattage per square foot. Trimming the heating cable would lower the resistance of the cable causing the system to overheat. Adding heating cable to the system would raise the resistance and the system would not heat properly.

Yes. The WarmlyYours TempZone™ floor heating system has withstood rigorous safety testing by the Underwriter's Laboratory and has received UL listing for the U.S. as well cUL certification for Canada. WarmlyYours offers thermostats that carry the CSA Mark and the UL listing, which certifies that the product has been tested under extreme conditions and meets applicable standards for safety and/or performance in the U.S. and Canada. All WarmlyYours thermostats contain a Ground Fault Circuit Interrupter (GFCI) which provides fail-safe protection against an electrical shock.

The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. The WarmlyYours TempZone™ Flex Roll electric floor heating system, for example, uses 15 watts per square foot. Based on a national average electricity rate of $.10/kW/hr, the approximate operating cost of an average bathroom using this system, measuring 8' x 10' would be between $.16 - $.21 cents a day. This cost is based on running your system a full 8 hours per day. Try our Operating Cost Calculator for a quick estimate.
