Customer Questions & Answers
How much does it cost to run an electric floor heating system?
The answer to this question will depend on a whole host of variables, including, but not limited to, the run time (for supplemental heating, we usually recommend between 4-8 hours per day), the heating system you're using, the total square footage, and your local electrical cost. Typically, the cost is just a few cents a day.
To figure out how much a floor heating system might cost to run for you, make sure to use our interactive Operating Cost Calculator.
How does electric floor heating compare to central or forced air heating?
Typically, electric floor heating is used as a supplemental heat source but in some cases, it can be used as a primary heat source. Electric floor heating is more energy efficient, less prone to spreading dust and allergens, and easier to control from room to room. Air-based heating systems can be used for both heating and cooling and can be a good way to control air quality in the home with regular maintenance.
For a more in-depth answer to this question, check out this blog.
Do I have to replace my floor to install a radiant heating system?
Yes. While there are some systems that can be installed beneath floor joists, most radiant heating systems will need to be installed beneath the floor itself. This is why the best time to install floor heating is during a remodel or as a part of a new construction, when a floor is being installed anyways.
If you're interested in alternative radiant heating methods, check out our Radiant Panels, which are wall-mounted and use infrared technology to provide supplemental heating.
What’s the difference between hydronic (heated water tubing) and electric floor heating?
Hydronic systems operate by using heated water pumped through tubing beneath the floor. Electric underfloor heating works with heated cables beneath the floor. Typically, hydronic systems are a good choice for new construction projects and electric systems are better for remodels or single rooms. This is because the high installation costs of hydronic systems (boilers, pumps, etc.) makes them cost-prohibitive for projects like a bathroom or kitchen.
For a more complete answer to this question, check out this blogpost.
How does electric in-floor heating work?
These systems work 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 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.
Do I need insulation when installing a floor heating system over a concrete slab?
When WarmlyYours floor heating systems are being installed on a concrete slab, we strongly recommend adding a layer of insulation over the slab 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.
What voltage does WarmlyYours floor heating systems utilize?
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.
How do I work with my electrician to install WarmlyYours electric floor heating?
While WarmlyYours 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.
What type of flooring can I install along with an electric floor heating system?
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 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.
What temperature will my heated floor reach?
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 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.
What is the total power/amperage that the floor heating system draws? Does this system need a dedicated circuit?
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 system.
I have extra cold lead wire. Can I trim off what I don't need for my installation?
Yes. Unlike the heating cable, the cold lead wires can be trimmed or lengthened with additional lead wire which can be purchased from WarmlyYours.
How will radiant floor heating affect my wood floor?
WarmlyYours nSpiration controls are equipped with an in-floor sensor to precisely control the floor's temperature to comply with the wood manufacturer's temperature recommendation.
How do I know if I am installing my floor heating system properly?
Please keep in mind that you must check your system with a Digital Ohms meter 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 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.
Is WarmlyYours Safe? What About EMF?
Our 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 can I determine what I need for my floor heating project? How can I find out what my floor heating system will cost?
You can use the Instant Quote Tool, which gives you many options for your floor heating coverage. Use this interactive tool to design your room online and receive an instant quotation with product recommendations, rough-in and installation kits, cost of your control, etc. Planning your floor heating project is made easy when using our Instant Quote Tool.
Send us your floor plan or fax it to (800) 408-1100 and we will send you a quote, product recommendation and a free custom installation plan for your project.
Can I use a floor heating system as a primary heat source?
Yes, in most cases, a 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’ 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.

Great Replacement For My Old Thermostat
Peter G., Dayton, OH on 02/09/2019
My old WarmlyYours thermostat bit the dust after 10 years. I was able to order the nSpire Touch Wifi directly from WarmlyYours. This is a vast improvement over the old one and it's nice having a simple UI for setting up the schedule as well as the other settings on the device. I use the Wifi setting from time to time when I need to adjust the temperature prior to going upstairs. Yes, having the Wifi interface is a little "geeky" given that once you set the schedule, I rarely adjust the temps/time, but every so often I use it. The manuals are clear and the setup was easy.
Great product, easy to install and user friendly.
Jason D., EDMONTON, AB on 06/20/2018
Great product, easy to install and user friendly. 24 hour tech support was very helpful as was the sales staff.
Smartest Decision I Made
Kent M., CHESAPEAKE, VA on 01/19/2018
Great product. Highly recommend. Looks great, UI is very nice and easy to use. Love having the weather and time displayed. Plenty of scheduling options. Love that it learns how long it takes to heat the floor and adjusts start time to meet the time at temp. Putting in this heated floor system was the smartest decision I made when doing the bathroom remodel, and having this thermostat (that I can also run from my phone) is the icing on the cake.
The nSpire Touch WiFi Thermostat is Amazing
Clint L., MANITOU SPRINGS, CO on 05/02/2017
The nSpire Touch WiFi thermostat is amazing. It is easy to program and control from either a web page or from a smart phone. It does a great job of sensing when to start a heating cycle to bring the room to temperature at the set time and seems to use the weather forecast, the room temperature sensor, and floor mat heat sensor in a very intelligent manner. Glad I went for that fairly expensive thermostat but expect it will pay for itself fairly quickly due to the level of control and intelligence it seems to have. Highly recommended.
Ron B., WATERLOO, IA on 04/20/2017
Works well. The app offers a very basic interface. That's no different than the unit interface. It works...
Easiest to Use Thermostat That I Have Ever Used.
Lisa D., OKEMOS, MI on 01/20/2017
