SunTouch UnderFloor allows you to retro-fit almost any type of floor with electric radiant heat without having to replace the existing floor covering.
UnderFloor is good for interior use only. It installs under existing wood subfloors that are accessible from underneath via crawlspace, basement or garage ceiling. The system is mainly for application in residential or light commercial areas. UnderFloor can be installed in any areas that require floor warming. The floor is heated directly by the mat installed under it.
If you need help selecting the right mat option for the room/area you want to use UnderFloor for please give us a call at (888) 594-7322 or email us your questions. We will be glad to help you get exactly what you need!
- Product Details
UnderFloor = Zero EMF
An emerging issue in the electric radiant heat industry is EMF (electromagnetic field) radiation. SunTouch pioneered and sells only ZERO EMF products constructed with active dual wire EMF-canceling technology.
All SunTouch products use a complex wire construction with two heating elements in parallel with an added and patented helical twist to eliminate EMF. Other electric radiant floor heating companies sell single-wire systems that release high levels of EMF when compared to SunTouch.
What is EMF? Electromagnetic fields (EMF) come from all electrical appliances, but studies show an average American's daily exposure is less than 1 unit (mG) of EMF. But. when you sit on an unshielded electric radiant floor, you may be exposed to 20, 40, or more times the average daily exposure. This Data comes from Independent testing. Read More Here
Is limiting exposure to EMF important? No one is certain. The World Health Organization says the data is inconclusive to date, but continues their research. We provide this EMF information because it is important to some people, not to frighten you or exaggerate any risk.
For many years customers have chosen SunTouch Zero EMF systems, but we leave the choice to you after explaining what we do know.
