Is electric floor heating safe and what about EMF?

Our electric radiant floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce much less EMF than common household appliances like your TV or vacuum cleaner. The EPRI (Electric Power Research Institute) tests all electrical devices and publishes the data. Many common household appliances are tested at a distance of 6 inches. The test results indicate that on average, the EMF emitted for the following appliances, measured in Milligauss (mG) units, is:

Vacuum Cleaner: 300 mG

Microwave: 200 mG

Portable Heater: 100 mG

Dishwasher: 20 mG

Washing Machine: 20 mG

WarmlyYours TempZone™ (Twin): 1.8 mG

What type of flooring can I install along with an electric floor heating system?

WarmlyYours’ TempZone™ product is most commonly installed under tile, stone, and marble flooring, but can also be installed under many other popular floor covering options such as hardwood, vinyl and linoleum. We also have our Environ system, which is an electric floor heating product as well and is specially designed for installation under carpet (in the U.S. only), laminate and floating wood. WarmlyYours can accommodate any flooring type with either of the electric radiant floor heating products that we offer. If your flooring type isn't listed here, just give us a call at (800) 875-5285 and we will be happy to discuss it with you.

If I have extra cold lead wire, can I trim off what I don't need for my installation?

Yes. Unlike the heating cable for electric floor heating, the cold lead wires can be trimmed.

Perimeter heat

Anthony P., Lingle, WY on 10/06/2023

I used these cables to keep a slab next to a freezer from getting condensate on the surface. They work great.

Easy Peasy!

Erin S., Santa Barbara, CA on 06/05/2023

I was able to make an educated guess about which product to choose from just the website, the WarmlyYours team was able to dial it in and turn around recommended layout drawings in just a week, pick up comments in a few days. Jessica S. followed up regularly with me and was able to get everything to the GC as soon as they needed it. A great process so far.

Order was correct and great quality merchandise
