Customer Questions & Answers
TempZone™ Cable has 86 Questions and Answers.
While WarmlyYours electric radiant floor heating systems are typically installed by your floor covering contractor, a licensed electrician is recommended for the final thermostat hook-up. With every quote, we provide an Installation Plan layout, together with an electrical plan that has all the info required for the electrician.

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
The floor heating systems are offered in both 120 volt and 240 volt for the North American market. A 208 volt breaker panel can also accommodate our 240 volt floor heating system. It is important to note that the energy consumption will be the same: a 240 volt system will not cost more to operate than a 120 volt system. You are billed in kilowatts, and the 120 volt and 240 volt systems use the same amount of kilowatts. WarmlyYours often specifies a 120 volt system in smaller projects while a 240 volt system is typically recommended for larger projects (120 square feet of electric floor heating coverage or more). The benefit of switching to a 240 volt system is the reduction in amperage. Our programmable thermostat can control a radiant floor system up to 15 amps. The 120 volt system will reach 15 amps at 120 square feet of electric floor heating coverage. However, the 240 volt system will reach 15 amps at 240 square feet of electric floor heating coverage, allowing a much larger system to be connected to the thermostat. For installations over 240 square feet, a relay contactor or power modules are needed.
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.

Best customer service ever!
Edward T., Spokane, WA on 10/24/2022
To my knowledge this is my first ever review - but WarmlyYours (WY) earned it! My wife and I (66 and 67 years ago) recently (couple months ago) completed our installation of the 847 feet 240 volt floor heating cable (Temp Zone Floor Heating Cable) for a new sunroom we had recently added (About 17' by 17'). We used the Prodeso matt under the cable and we installed 18 by 18 ceramic tiles as the flooring surface. We also purchase the n-spire programable thermostat. Our contact person at WY was Jennifer Stasica (Melus) and she was phenomenal. We went thru several (actually many) design and product options before settling in on the ceramic tile as our flooring option. I had a little trouble getting the thermostat connected but the WY tech team was Johnny on the spot and quickly helped me get the thermo connected. For full disclosure my wife and I are both pretty handy - but the instruction from start (checking cable) – to finish (connecting thermos) are spot on and easy to follow. I also took the time to contact Custom Building Products tech support for their recommendation on the bonding primer (we put down on plywood floor) and best thin sent to use in this application (bonding primer MBP and thin set ProLite Premium Large Format). We used the two-step method for installation, i.e Thinset the Prodeso, lay the cable according to the WY supplied plan, then set wire into Predeso and an finally title onto the covered Prodeso/heating cable. I will not hesitate in using WY for any future heating projects but I am thankful this large project is completed. For a bathroom etc. putting down Temp Zone cable would be an easy project. Thank you again Jennifer - and pass on my thanks to your engineering team for the many renditions we worked thru. PS another reason I waited to do this review was to see how the heated floor performed. No really cold days yet - but on the cooler evenings it is meeting my expectations.

Great product. Easy to quote, easy to order and arrives quickly. Staff is always helpful. Most important, our customer loves their new heated floor!
Elman B., Worcester, MA on 07/28/2022
The designer did not listen to my instructions. I told the salesman that the floor was highly insulated below the subfloor and that the vinyl covering had a temperature limit of 85 degrees. He specified your hottest possible arrangement for the floor size. (Three inch spacing with 3.7 watt wire and very narrow areas at the edge.) It should have had 4 or 5 inch spacing with your cooler 3.0 watt wire. ) I did not catch it until I had it for a while and was very bothered that it was too hot. Eventually I had to send it back and order a much shorter wire.
Response from WarmlyYours:
I'm sorry, we no longer stock the older-style 3 watt cable in a size that is required for your space. We apologize if there was a mixup in our discussions with you. We have historically had very good results with 3.7 watt cable spaced at 3" for enclosed porches. Enclosed porches are usually subjected to high amounts of heat loss, even if the floor is well insulated. It is better to have plenty of BTUs with some to spare than to not have enough. The thermostat that you purchased comes with a floor sensor. With the floor sensor installed in the floor, the thermostat can be set to limit the actual floor temperature to a specific temperature. This "Floor Limit" can be set to any temperature that you desire, or is required by the flooring manufacturer. The floor temperature will not exceed the value you enter, whether the wire is spaced at 3" or 4". We have found that 4" wire spacing works well in a second floor room with a heated room below, but may not have enough output for an enclosed porch. We rarely, if ever, quote 5" spacing because of "striping" of the heat which can result in cold spots in the floor. In the end, we always design a system that we believe will consistently deliver a great result. Thanks for your feedback, we appreciate it.

I was going to use a competitor's product, but every place that 'carried' it I also had to order it. Since the tile guy was coming over on a specific date I needed to make sure everything was in place, & based on experience I couldn't trust Lowe's or HD's site when it said it would come in by a Wednesday of the week needed. I called WarmlyYours, they confirmed that they had all the items in inventory & could ship the same day. I texted the bathroom plans and later that day they got back w/ the design and a quote. I ordered it that Friday afternoon, and was shocked that it showed up at my door the next day-Saturday. Everything went as stated. Very nice when facing delays w/ so many of the other items in our project.

They verified my order before I ordered the products so i got what I needed. Speedy delivery as well
Wish we did it 15 years ago
Questar W., Riverhead, NY on 04/18/2022
Adding the radiant heat to our bathroom floor was the best improvement we have done in out house in years. It changed our late night winter trips to the bathroom. The floor was always freezing and even stepping out of the shower was a shock to the senses. Now its a pleasure to feel the warmth. The customer support is very helpful and thorough which is rare today. I had a condition where the floor would not go above 83 and I assumed there was a problem with the install. I spoke with a rep for a long while about this problem. An hour later i received a call advising me to check if the thermostat was set to laminate flooring instead of tile. It was. Problem solved. I highly recommend WarmlyYours if you are considering radiant flooring.
Great product and customer service

The floor heating cable was simple to install and works great. Troy’s customer service was awesome as always and the turnaround time on his floor layout was very prompt. Delivery of the heat cable and thermostat was very fast also, only took a couple days.
