| Why Helps | WarmWire = Zero EMFElectromagnetic fields (EMF) are generated by all electrical devices, and the possible dangers of exposure to EMF are still the subject of debate and scientific research. Out of concern for their customers' safety, SunTouch created the first EMF-canceling electric radiant floor heating system in 1993, and to this day they only manufacture and sell floor heating systems that use their patented EMF-canceling design. We provide this EMF information because it is important to some people, not to frighten you or exaggerate any risk like others do. We simply aim to inform you and leave the choice up to you after explaining what we know. |
