About EMF Emitted by Radiant Floor Heating Systems

WarmWire is the ONLY manufacturer that has undergone INDEPENDENT testing for EMF or Electro Magnetic Field emission. The results of this testing shows WarmWire Floor warming to be the SAFEST with the LOWEST emissions. See the results don't just take a website's claims as truth or believe everything you read - look To WarmWire for Safety and testing to support our statements.
EMF stands for Electro Magnetic Field and is a byproduct of alternating electric current passing through wires and appliances. Human exposure to ambient levels ofEMF is the subject of continuing scientific scrutiny and the results are a matter of public record. For those who are concerned, the Federal Government recommends minimizing exposure to EMF in the home and workplace. Elevated EMF levels can also interfere with electronic devices including computer screens and audio equipment and is usually included on lists of causes for “sick building syndrome” and sources of interference.
There is no practical technology to completely shield an electric heating element in order to minimize EMF. The only viable approach is to spiral two wires side by side so the fields cancel each other. Watts Radiant innovated this approach years ago and was granted U.S. patent number 6,303,905. The EMF generated at floor level by radiant floor heating systems that use only one wire is many times normal ambient levels. Using dual wires for EMF cancellation is more expensive, but it is the safest choice. Any single wire heating element used in radiant floor heating is a compromise and should, in our opinion, be avoided.
Safer electronic emission practices have been adopted by manufacturers of microwave ovens, video monitors and cell phones to name a few. WarmWire has already taken this important step and is another reason why it is your safest and best choice for Floor Warming.   Other Manufacturers minimize the importance of EMF…Could this be because they do NOT meet the same superior standard WarmWire meets? Is it worth the risk to you and your family? We do not think so.

    Can you splice two separate lines together to make one?

      Hi Clint,

      Since these are resistance heating cables, they cannot be spliced together or cut short. This would change the resistance of cable and cause it to heat improperly and possibly to fail.

      You can hook up to 3 mats or cables up the same thermostat though to cover a larger area as long as the combined amperage of the cables is no more than 15.

      Warm Regards,
