Common Support Questions


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.

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.

When installing electric floor heating over a concrete slab, an insulating underlayment like CeraZorb is highly recommended to ensure efficient operation, faster heating times and warmer floor temperatures.

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 120 square feet of heated space, then you may need a larger breaker plus additional controls. No matter what the size of the area you choose to heat, we recommend a dedicated circuit for your electric radiant floor heating system.

We usually recommend that you have an individual thermostat for each room. However, if it's an open floor plan and your local electrical code allows you to have one controller for the whole area, then it's definitely possible to have it all controlled from one thermostat.

Yes, in most cases, an electric floor heating system can be effective as a primary heat source. However, our TempZone™ and Environ™ systems are 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’ electric radiant 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.

The temperature of your floor can range anywhere between 75°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 should easily reach a comfortable temperature of 85 degrees Fahrenheit, if the electric floor heating system is installed correctly. 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.

Electric floor heating works by having an electric heating cable installed underneath the flooring (embedded or floating, depending on the system and floor type), which is then wired to a special thermostat (either one specifically designed for electric radiant floor heating, like a WarmlyYours’ nSpiration Series control, or a third-party thermostat). When turned on, the heating cable emits heat upward through the flooring which is then radiated throughout the room, heating all solid surfaces.

Our thermostats are indoor rated. So long as they are kept within normal indoor humidity levels, they will continue to operate optimally. These thermostats are not rated to be installed in wet areas, steam rooms, or rooms with abnormal humidity levels or poor ventilation.

Electric-resistance heating cables and systems have no polarity. This includes all current WarmlyYours heating elements.

One thermostat can control multiple heating mats/cables as long as all the elements are using less than 15 amps. For TempZone™ Flex Roll systems for example that would be maximum of 120 sq.ft. for 120V systems and 240 sq.ft. for 240V.

How to figure out the Kilowatt Load usage for your floor.

On the new touch screen thermostats, during the startup menu, users will be prompted to enter their KW load usage. A lot of our customers may not know this for a number of reasons (they did not install or order the floor, it may be a replacement and info on the install has been lost, etc.) Here is an easy way to help out and get the KW load they need for this menu step.

Kilowatt load usage can be figured by taking the square footage of the open floor space multiplied by 15 (for tile) or 12 (for carpet and laminate). This gives us the total wattage which we then divide by 1000 to get the Kilowatts.

An example. User has a 100 square foot room that is tiled. The math would look like this: 100 sq feet X 15 watts per square foot = 1500 divided by 1000 = 1.5 KW

The default is 10k.  If this is a new installation, that is the answer.  In the very rare occasion that this is replacing a 12 year old or older Energy stat (square OJ Microline from before 2010 with red and green sensor wires), choose 12k.  If this is a replacement for the other 99% of the other thermostats we sold (Honeywell TH115 and TH111 thermostats), 10 k is the value.

Always start with the default 10k and change later if needed.
