I have used Warmly Yours floor heating mats several times over the past 5 years (in fact I picked up the first one at the original house location in Long Grove) and never considered the EMF question until I read some literature from another company that claims to have a zero EMF system. Their position is that an EMF could be possibly be harmful to a person lying on the floor for an extended period of time and could interfere with TV, mobile phone, etc. tranmissions. What is the Warmly Yours situation regarding EMF?

Bob,

Sorry about the delay on getting you an answer. EMF has become quite the topic over the last few months. Firstly, anything that has electricity flowing through it produces some EMF. The debate over whether or not electromagnetic fields are harmful has been going on for years; as of yet there is no concrete study that shows any substantial heath risks associated with EMF.

One of the interesting properties of electromagnetic fields is the rate at which the effects diminish with distance from the source. Standing directly under high-voltage power lines will expose you to quite high levels, but at a distance of 300 feet the effects have all but disappeared.

Our system has been tested to IEC standards 61000-6-1, 61000-6-4, and CISPR 11. At a distance of 1” the testing rendered an EMF result of 1.8mG. This is almost 600 times lower than the assumed safe level for EMF exposure. To put this in perspective the computer monitor you are sitting in front of right now is producing an average of 67.45 mG at a distance of 1’.

As our system is set in a layer of thinset cement and then tiled over, you are almost always farther than 1” from the system. The EMF at that distance is completely negligible.

I hope this clears up some of your questions, if anything else comes up, please don’t hesitate to contact me in the office.
