STEP Residential™ - Heating bathroom floors, homes and kitchens

STEP Residential™ 12" (30cm) wide radiant heating element is designed to provide healthy, even and comfortable warmth in a home. This element is ideal for both new construction and renovation.

The Residential heating system can be used to floor warming or as the primary heat source and can be installed under most floor coverings, including tile, stone, hardwood, engineered wood, laminate and carpet. Heating bathroom floors or larger areas will not only increase the comfort, but will also reduce the heating bills. The self regulating properties of the flat 12" wide heating mat makes the heating solution extremly energy efficient compared to any other heating source.  For total heating a heat loss calculation is required.

Take away the chill of cold floors and experience the comfort of heated floors in the bathroom, kitchen or whole house. For even heat distribution, maintain spacing between element strips at 2-3 inches (5-7.5 cm).
