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

What type of flooring can I install along with an electric floor heating system?

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 electric radiant floor heating products that we offer.

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.

The company was great

Jeff G., New Windsor, NY on 11/06/2016

The company was great. After drawing up a floor plan it went unnoticed that the dimensions of the room were wrong resulting in a cable that was way to long. This was realized once the cable arrived to be installed. Calling up for support they tried to reconfigure the layout to no avail. They kind folks at WarmlyYours re-drew the room to the correct dimensions, took back the too long cable, and shipped the correct length in addition to giving me a price adjustment based on the shorter length. The install went well and now I am enjoying nice warm tile floors in my office. Diane was involved throughout the whole process, being very understanding and supportive.

Instructions were very thorough

George W., Erie, PA on 09/10/2016

Everything has gone real well so far. Installation went good and initial start-up went without a hitch. The instructions were very thorough making installation easy. The cable checking throughout installation gave me piece of mind there are no problems under tile. Haven't needed to use yet but that will change in the next month or two.

We love the heated floor!

Tony S., Farmville, VA on 04/18/2016

We love the heated floor! My wife was skeptical until the first cool night; now we never want to go back to cold tile.

Far surpassed our expectations

Robin R., Lake Zurich, IL on 04/16/2016

I love my heated floor! It far surpassed our expectations and has even heated the room which is on a north wall. The pipes froze the previous year and that hasn't happened since the heated floor went in.

No increase in electrical bill

Steve M., GOSHEN, IN on 04/16/2016

We love it! No more cold feet on the tile! Easy to program on/off times and seen no increase in electrical bill.

Works well.

Joe M., White Bear Lake, MN on 04/16/2016

Works well. Wiring connections to the second conductor (sheathing) is difficult.

WarmlyYours was very attentive

Chris D., Spearman, TX on 04/16/2016

Everything needed to install our new floor heating system was delivered as promised. I was able to install the support structure and heating cable with no problems. The customer support team at WarmlyYours was very attentive and provide all the installation guidance that I needed. It has been 6 months since we moved in and the heated floor is one of the best parts about our new house. I would recommend your product to anyone!
