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

If I have extra cold lead wire, can I trim off what I don't need for my installation?

Yes. Unlike the heating cable for electric floor heating, the cold lead wires can be trimmed.

How do you keep a sunroom warm in the winter?

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.

Anonymous, Tahlequah, OK on 12/30/2023

I replaced my thermostat and it works much better. I hope these thermostats last longer. I am not sure what is their life. Thanks for the help.

Another successful installation!

Jeff W., Downingtown, PA on 12/21/2023

Once again we have made another customer happy with and grateful for a WarmlyYours heated floor!

I'm glad I went with WarmlyYours over Home Depot

Joshua C., Portland, ME on 12/11/2023

I purchased a radiant floor heating system from your company in November. I wanted to reach out to let you know how impressed I was with Pedro Banuelos. My wife and I are real estate investors and this is our 3rd home. It's a duplex that we've been renovating for 18 months so we've dealt with a lot of vendors. I've also served on two HOA boards so have had my fair share of interactions with vendors from those experiences as well. Pedro's customer service stood out from every company we've dealt with. From the moment I engaged with him he was professional, listened, and was extremely knowledgeable about the product line. I was also impressed by his demeanor. He was by no means pushy and truly came across as wanting to be helpful. I definitely appreciate that being in software sales myself, it's not an easy line to walk and he did a great job. At any rate, I just wanted to drop you a line and let you know how impressed I was and I'm glad I went with WY over Home Depot; and truthfully it was all b/c of Pedro! Thanks and happy holidays!

quality ,performance and advise are excellent

C/o S., St. Albert, AB on 12/10/2023

Mary is the best

Steve J., San Diego, CA on 12/02/2023

I’ve been working with Mary for a number of years. She’s been nothing but helpful patient and caring. As for the product I’ve never had a problem installed many thousands of square feet and will continue using it in the future.

Great system

Anonymous, Timnath, CO on 12/01/2023

The system works as expected and was a lot easier to install under tile than was thought.

Our bathroom is now WARM!

Peter H., Lake Zurich, IL on 11/25/2023

We took the bathroom down to the studs and subfloor and installed WarmlyYours floor coils plus two ceiling panels, plus fresh paint and floor quartz slabs. We are now sandwiched between two layers of warmth, which we really appreciate now that winter is here.

great as usual

Dellavalle L., East Stroudsburg, PA on 11/24/2023

i didn't have any source of heat in this room. i chose to install a hot air line from my furnace. it wasn't that effective. then while ordering the new floor mats for my next house remodel 3 bathroom floors. i decided to just do it in my dining room too. this meant remove the dining room table etc. remove the LVL floor. under the flooring was a hand written note from the original builder. that was a cool find. i installed the mat ran all the wiring and then poured the floor leveler on top which was the most important thing as i someday may tile this floor. but i went and installed life proof flooring on top and man. Thanksgiving was so comfy and pleasant in the dining room. the time it tommy to install was about 5 hours and the flooring took a day with all the molding's etc. The comfort you get from radiant heating is priceless in my head

My 2006 warmly yours in floor heat is back online!

Tim G., Kent, WA on 11/05/2023

My original Thermostat from 2006 suffered a short circuit internally and quit suddenly. I was grateful to find WarmlyYours still able to provide a new updated Thermostat for me. I love the new touch screen, with wifi and remote control. A very nice upgrade! Thanks WarmlyYours! Yours Warmly, Tim G.

TempZone™ Floor Heating Cable

David H., Maple Ridge, BC on 10/29/2023

We installed heating cables in a kitchen, dining room, and hallway spanning around 1000 square feet. We didn't have complete layout information from your client, but you managed to complete the installation successfully with an additional roll of heating cable. It's great to hear that Jenn, the service representative, provided excellent technical support and offered a competitive price for the project. Well done!
