Experience the ultimate in radiant floor heating with the WarmlyYours TempZone™ Floor Heating Kit. This all-in-one solution combines the flexibility of our TempZone™ Floor Heating Cable, the reliability of GripStrips Fixing Strips, and the ease of control from the nTrust 2.0 Nonprogrammable Thermostat to deliver consistent, energy-efficient warmth to any space.
Unmatched Comfort and Flexibility
At the heart of this kit is the TempZone™ Floor Heating Cable, designed to bring customizable comfort to your floors. This ultra-low EMF twin-conductor cable features a 15' cold lead and is available in both 120V and 240Voptions, with various lengths to fit any project. With 9-15 watts per square foot of heating power, it provides efficient and even warmth while allowing complete installation flexibility—perfect for irregularly shaped rooms.
Secure, Hassle-Free Installation
For a smooth and secure installation, this kit includes GripStrips Fixing Strips. These plastic strips firmly hold the heating cable in place with precision spacing, ensuring optimal heat distribution. Unlike metal fixing strips, GripStrips offer a safer, more durable alternative, and their interlocking design allows for easy lengthwise snapping for a seamless fit. Whether anchored to the subfloor or adhered using a separate adhesive, these strips keep your heating cable tensioned and secure throughout the installation process.
Reliable, Effortless Control
Enjoy effortless temperature control with the nTrust 2.0 Nonprogrammable Thermostat. Designed for simplicity and dependability, this thermostat features a sleek LED display with capacitive touch controls. With a built-in self-testing GFCI for added safety and dual-voltage compatibility (120V/240V), it ensures efficient operation for any heating system. The included 10k ohm floor sensor provides accurate temperature readings, keeping your space at the perfect warmth without constant adjustments.
Added Peace of Mind
To ensure a smooth installation process, the kit also includes the Circuit Check testing device.

Customer Questions & Answers
TempZone Cable Kits with Fixing Strips and nTrust 2.0 LED Touch 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
29 people found this helpful. Did you find this helpful? Yes NoIf I have extra cold lead wire, can I trim off what I don't need for my installation?
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

Great to deal with! Made everything super easy and transparent and easy to understand.
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.
Great
Anonymous, Chateauguay, QC on 05/11/2025
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!
Best customer service!
Anonymous, Towson, MD on 04/07/2025

What really sets WarmlyYours apart is their outstanding customer service. They will help you select the right product and are extremely friendly and knowledgeable. 5 stars!
Great customer service
Dennis K., Joseph, OR on 04/05/2025
I needed a new thermostat for my heated floors in the kitchen. They helped me pick out the one I needed and even gave me a discounted price. Shipping was not real fast, but once I received it, the installation was a breeze and my floors are warm again. Customer service also followed up on the order a couple of times to make sure I was satisfied, which was impressive.

Lucy S., Hampton, NJ on 03/24/2025

Warm Support—Even Beyond New Jersey
Anonymous, Hampton, NJ on 03/24/2025
Thank you for all your help with my thermostats and my orders. Letting you know I won’t be in New Jersey anymore. I’m moving to a warmer climate with my daughter and her children. Thanks again for all your help.
Great Product
Mark A., Ottawa, ON on 03/23/2025
The company was easy to deal with, had great and responsive customer service. Just powered up the floor today. It sits under self levelling cement and floor tile and took a couple of hours to warm from 19C to 28C.
