Frequently Asked Questions
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
Please keep in mind that you must check your electric floor heating system with a digital ohmmeter in conjunction with a Circuit Check™. Take an initial reading as soon as you take the product out of the box to verify that it is within -5% / +10% of the values stated on the product’s label. This will give you a basis of comparison for future readings. Take a second reading once you have positioned the system to match your custom installation plan. It is also advisable to take an additional reading in the middle of the tile installation, just to make sure that the Circuit Check™ is doing its job. Then, take a final reading when you are finished with the floor installation and are ready to hook up the thermostat.
The Circuit Check™ is a tool developed by WarmlyYours to give you peace of mind and ensure trouble-free installations. Simply hook up the cold leads to the tool while you position the system to match your custom installation plan.
The Circuit Check™ will continuously monitor the continuity of the circuit during the installation of your system and during the installation of your flooring. The Circuit Check™ beeps immediately when a short in the system is detected, alerting you to a potentially damaged cable in the area you are working, before you lay the tile over the electric floor heating system. The WarmlyYours technical support team is available 24/7 to provide assistance if the alarm sounds, or if you would have any questions during your installation.
Since most Luxury Vinyl Tile (LVT) manufacturer's set a maximum temperature for radiant floor heating, the system should have little to no effect on the rubber/cork backing.
Pre-attached backing can act as an insulating layer though, meaning it can prevent the radiant heating from efficiently directing heat up through the floor. Please check with the manufacturer for the r-value of the product. Look for an assembled plank with an r-value of less than 1. The lower the r-value, the better!
The breaker and wire sizes are selected based on the total amperage of the WarmlyYours heating system connected to a single thermostat. This information is on the WarmlyYours heating system's installation plan, electrical plan, or UL label. Based on guidelines from the National Electrical Code: loads up to 16 Amps may utilize 12 gauge wire with a 20-Amp breaker, and loads up to 12 Amps - 14 gauge wire with a 15-Amp breaker. Local code and/or other factors may change these guidelines.

The order process was very good. The ability to be able to draw your space and input the known pieces where heat is not required was great.
Warmly Yours is such a great company!
Burgessdesignstudio, Davidson, NC on 09/22/2025
From the website, our initial contact with sales rep, through engineering design, purchase, delivery, technical support through installation and post installation, everything was seamless, and all staff were very professional and knowledgeable. I am 100% satisfied, thanks to all.
Great Product!

We have used their products for over 15 years and have never had a problem. We have had questions and their customer service is exceptional. I have never had a call back to repair a WarmlyYours product.

Excellent customer service from Pedro
Great product
Lbc I., Lindenhurst, IL on 08/26/2025
Easy communications and great delivery
Fabulous... and then awful
Anonymous, Granville, OH on 08/25/2025
Ordering was pretty straightforward, and then when I had a design change, Pedro was tremendous in helping me work through the shift. I had to return one roll and get a smaller one to fit the space. All was great... until I got an email saying that my return wasn't accepted, and the $800+ refund I anticipated was now $250. Apparently there was a torn label on the return and that triggers the non-re-sellable policy. If I had returned damaged goods, then sure, I understand the problem. But this is a terrible way to treat a long-time repeat customer, and it really sours me on wanting to do business with the company again. From "WarmlyYours" to "ColdlyYours."
Warm for your feet
