Our electric floor warming cables and prefabricated warming mats have been keeping stone, ceramic and engineered wood flooring comfortable for over 40 years. The cables are easily installed over plywood, concrete or cement backerboard subflooring, and can be embedded in thinset or self-leveling underlayment. EGS Electrical Group offers a mat system that can be embedded directly in concrete floors to provide thermal storage for comfort and potential energy savings in garages, barns, workshops and basements.
