Customer Questions & Answers
TempZone Cable Kits with Fixing Strips and nJoy WiFi Thermostat has 17 Questions and Answers.
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

How do I know if I am installing my electric floor heating system properly?
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.
14 people found this helpful. Did you find this helpful? Yes NoWill the radiant heat affect the attached rubber or cork backing on Luxury Vinyl Tile? Does the attached backing have any effect on the floor heating system?
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!
What breaker and wire size do I need to use for a floor heating system?
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.

Jennifer was awesome
Mike C., Basalt, CO on 06/17/2025
Great to deal with! Made everything super easy and transparent and easy to understand.
Easy installation. Set-up a little more challenging.
Carol L., O'fallon, IL on 06/09/2025
Installation was easy. We did have some initial problems with pairing the thermostat with my iPhone, however. After talking with tech support, I was advised to attempt the pairing process multiple times. Eventually the pairing was successful. Although a bit frustrating, we were finally able to program the thermostat successfully and it is working fine.
Response from WarmlyYours:
Thank you for your review. The issue that you are referring to stemmed from a security setup quirk present on IOS devices. Now that we have learned how to configure the bluetooth settings in iPhones, this situation has been resolved and the setup can be done very quickly and easily. - Scott, Technical Support Manager.
Works well - thanks!

Works well - thanks!
Excellent Customer Service
Laura H., Santa Monica, CA on 05/22/2025
I called WarmlyYours with an issue regarding my heated floor. They quickly determined my 15-year-old thermostat was no longer working, sent one to me within a week and gave me the contact information of someone who could install it. My floor is up and running!
A responsive team, easy to work with…
Anonymous, Arlington, VA on 05/21/2025
I selected WarmlyYours from a host of competitors due to the woman-owned business and small business status. They offered better customer service throughout the installation process, from mechanicals, to setting the mesh under marble tiles. It went very smoothly and the heating system works.
Will remain a loyal customer
Kevin B., Norton Shores, MI on 05/12/2025
I bought the updated thermostat to replace the old one that was no longer working in my customer's home. Their videos helped me diagnose the problem. The install was super straight forward. Their customer service is legit. I don't have heated floors in my home, but am putting them in my bathroom later this year. I will for sure use the WarmlyYours system, no question.
Great

Fixing strips are on the cheap side but were free and did the job. Heated floors are a wonderful addition to the house.
Toasty Feet :-)
Kathie S., Scottsdale, AZ on 04/30/2025
We have just used our new shower for the first time and we are thrilled to have toasty feet when we step into this beautiful enclosure. This is the 3rd time we have installed your product and although I hope to never move again - I will be recommending your product to all my friends and family.
Love the warmth
Anonymous, Knoxville, TN on 04/10/2025
Was unsure but it was a small area and decided to proceed. No regrets what so ever. Love the warmth radiating from the tile floors! The installation was somewhat of a challenge for my inexperienced husband. But installed now….no looking back!
Great product. Great service!
