  • STEP Residential™ is designed to provide even and comfortable warmth in a home. The system is ideal for both renovation and new construction.
 
  • STEP Residential™ can heat the whole house our just single rooms. A heat loss calculation is required when total heating is expected.
 
  • STEP Residential™ can be used under almost any flooring including, tile, stone, wood, laminate, resilient and carpet.
 
  • STEP Residential™ can also be installed under the subfloor between the joists when the existing flooring is to be maintained.
 
  • STEP Residential™ operates on 24 volts and is normally connected to a transformer but it can also be run on solar or wind power.
 
  • STEP Residential™ is self-regulating. As the material gets warmer, less electricity passes through the plastic – therefore it is extremely energy-efficient.
 
  • STEP Residential™ is strong, thin and flexible, easy to install and can be cut to size on the job site.

Did You Know?

Studies from the "Sick Building Syndrome" show a direct relation between indoor climate and symptoms such as fatigue and headaches.  Research shows that thermic indoor climate is also related to productivity.  The level of comfort with radiant heat at lower temperatures increases productivity by 20-30%.
