Electric floor warming system used to heat tile flooring. The system is designed to heat the designated square footage when installed in mortar under tile or masonry flooring. The heating element is spaced 6-7″ apart across the heated area. This allows for simple coverage of any shaped area. The heating element is less than 1/8″ thick, so the rise in flooring height is negligible. We offer a 20-year warranty on its product. Product Life is 50 years.
