Customer Questions & 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.
Sunrooms can be very cold during the winter months. While a furnace may push some warm air into the room, the large number of windows, exterior walls, and other causes of heat loss in a sunroom will typically keep it from having a comfortable temperature level. Floor heating and radiant panels will add radiant heat, which the human body absorbs faster than other forms of heat, to the room so that it feels warm even at lower temperatures.

Brad S., Des Peres, MO on 07/11/2022
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.

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.

I recently purchased a floor heating system and was not surprised one bit. The consistency in quality of WarmlyYours products and customer service is unmatched. I have been purchasing their products and working with Tech support for 14+ years and could not be happier. The best!!!
Customer loves it
Craig C., Richmond Hill, ON on 02/19/2022
When I renovated the first bathroom I installed a heated floor. Loved it so much she wanted the second bathroom to have the heated floor. One day I will have it in mine!
Was easy to install but hard to activate properly
David S., Edmonton, AB on 02/06/2022
The installation was straight forward. The instructions were to place the heat sensor 2" from the heating cables. However, we used the standard 3" configuration so it was only possible to achieve a 1.5" separation. I'm thinking this may be the reason we can't achieve a comfortable heat setting for the system. Will still try to modify the settings to get it to work properly.
Brian B., Lakewood, CO on 02/05/2022
This was easy to install and works great. My floor is at a constant 77 degrees. The customer support was very friendly and helpful. I would certainly buy this again.
