Yes, in most cases, the TempZone™ floor heating system can be effective as a primary heat source. However, the TempZone™ system is most commonly used as a secondary heat source, providing floor to ceiling radiant heat to any room in your home where you desire more warmth and comfort. If you are considering electric floor heating for an addition to your home, such as a sunroom where you have no other source of heat, WarmlyYours offers an innovative online tool which calculates approximate heat loss. This tool can help you to determine if a WarmlyYours floor heating system will provide your desired comfort temperature throughout the year. You can access the heat loss calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.
When WarmlyYours floor heating systems are installed on a concrete slab, we strongly recommend adding a layer of insulation prior to installing the system. While our systems provide up to 25% more heating power per square foot than many of our competitors, the slab will always act as a "heat sink." Some of the heat that would otherwise be transferred to the flooring surface will remain in the slab, causing the floor’s surface temperature to be considerably lower. This is true with any floor warming system. When installed on top of a concrete slab without insulation, it is generally accepted that a radiant floor heating system will take the chill away from the floor and provide a small amount of warmth. Adding insulation on top of the slab and beneath any floor heating system will allow a greater percentage of the heat generated to transfer to the flooring surface. This results in greater efficiency and therefore faster warm up times, higher expected surface temperatures and lower energy usage. The floor will have the capacity to warm to a comfortable temperature, and in some cases can be employed as the primary heat source for that room. The recommended types of insulation are natural cork, insulated tile backer boards and insulated underlayment, such as CeraZorb synthetic cork.
Our floor heating systems have withstood rigorous safety testing and earned the UL listing. They produce significantly less EMF than common household appliances like your TV or vacuum cleaner. For more information on the subject please see our EMF information page.

Please keep in mind that you must check your system with an Ohms meter in conjunction with the Circuit Check™. Take an initial reading as soon as you take the product out of the box and this will give you a basis of comparison for future readings. Take a second reading once you have positioned the mesh roll 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. Once you have positioned the mesh roll to match your custom installation plan, simply hook up the cold leads to the tool.
The Circuit Check™ will continuously monitor the continuity of the circuit during the actual 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 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.

TempZone™ single and twin conductor mats allow for 25% more heating capacity as compared to many of the competitive systems to provide faster floor warm-ups.

WarmlyYours SmartStat™ is equipped with an infloor sensor to precisely control the floor's temperature to comply with the wood manufacturer's temperature recommendation. For more information, please visit our floor heating under hardwood page, where you will find detailed information and industry research performed by WarmlyYours and Launstein about heated hardwood floors.
Yes. Unlike the heating cable, the cold lead wires can be trimmed or lengthened with additional lead wire which is available from WarmlyYours.
No. Never cut the heating cable; cut the mesh ONLY. The floor heating cable is designed with a very specific resistance in order to consistently maintain heating at 15 watts per square foot. Trimming the heating cable would lower the resistance of the cable causing the system to overheat. Adding heating cable to the system would raise the resistance and the system would not heat properly.
Yes. The WarmlyYours TempZone™ floor heating system has withstood rigorous safety testing by the Underwriter's Laboratory and has received UL listing for the U.S. as well cUL certification for Canada. WarmlyYours offers thermostats that carry the CSA Mark and the UL listing, which certifies that the product has been tested under extreme conditions and meets applicable standards for safety and/or performance in the U.S. and Canada. All WarmlyYours thermostats contain a Ground Fault Circuit Interrupter (GFCI) which provides fail-safe protection against an electrical shock.
TempZone™ is an electric floor heating system that operates like an electric blanket for your floors. TempZone™'s fiberglass mesh backed cable is covered in thinset and is installed over top of your subfloor and beneath your flooring. The system provides a warm, even temperature across your floor generating floor-to-ceiling radiant warmth to transform these naturally cold surfaces into warm floors. Ideal for kitchens, bathrooms or any room in your home where you would enjoy radiant warmth and comfort, the TempZone™ floor heating system is easy to install, operate and maintain.
The amount of amperage draw depends upon how large the area is that you are heating. For coverage of areas less than 30 square feet, the system will draw less than 3 or 4 amps. If you have a larger area over 150 square feet of heated space, then you may need a larger breaker. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your system.
The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. The WarmlyYours electric floor heating system uses 15 watts per square foot. Based on a national average electricity rate of $.10/kW/hr, the approximate operating cost of an average bathroom measuring 8' x 10' would be between $.16 - $.21 cents a day. This cost is based on running your system a full 8 hours per day. Try our Operating Cost Calculator for a quick estimate.
WarmlyYours 25-Year No Nonsense™ Warranty is the most comprehensive warranty in the industry. In the event of a defect, we cover not only the repair or replacement of the Tempzone™ warming roll, but ALSO any labor AND materials required to perform the repair. For all of the terms and conditions of our No Nonsense™ Warranty, visit our products section.
The temperature of your floor can range anywhere between 75&def;F to 95°F. The floor's actual temperature will depend on a number of factors including the amount of heat loss that the room experiences as well as the room’s configuration. For instance, the warmth contained in a two story entry way would likely be less than that of a smaller, more enclosed area such as a bathroom. In a bathroom that is located on the second floor of your home or over another floor in your home that is typically heated, the temperature of your heated floor will easily reach a comfortable temperature of 85 degrees Fahrenheit. For the heat loss calculation for your specific room, you can access the heat loss calculator or you can call us at (800) 875-5285 and a Customer Service Representative will make the calculation for you.

Tempzone™ floor heating system is offered in both 120 volt and 240 volt for the North American market. A 208 volt 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 generate 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 110 volt system will reach 15 amps at 120 square feet of electric floor heating coverage. However, the 220 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 is needed.

TempZone™ single conductor is comprised of a double-insulated, coaxial heating cable stitched to a fiberglass mesh. The total thickness of the system is 1/8 inch and will not noticeably affect the height of your installed flooring.

TempZone™ twin conductor is comprised of a double-insulated, coaxial heating cable that is taped to a fiberglass mesh. The total thickness of the system is 3 mm x 2 mm thick and will not noticeably affect the height of your installed flooring.

While WarmlyYours systems are typically installed by your floor covering contractor, a licensed electrician is recommended for final thermostat hook-up.
