SunTouch UnderFloor is a safe and efficient radiant electric floor heating system retrofitting an existing cold floor with heat without disturbing the existing floor covering.
UnderFloor is for interior applications only and is intended only for installation under an existing wood subfloor (accessed from underneath via crawl space, basement, or garage ceiling) in residential and light commercial installations.
Insulation is essential after mats are installed into joist spaces.
We recommend SunTouch UnderFloor Mats be installed in all areas where floor warming is desired; the floor is only warm directly over an installed mat.
If UnderFloor is being installed to heat the space, first perform a heat loss calculation to determine the amount of BTUs required to heat the space.
UnderFloor = Zero EMFAn 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. |
