Getting Started

Did You Know?

Indoor Air Quality is directly correlated with respiratory illness.  The last thing you want your mechanical system to do is to distribute dust, mold spores, pollen, and other particulates throughout the structure. Because radiant heat does not blow allergens, it helps those with allergies and asthma find dramatic improvement to their symptoms.
 

Attention Customers

Beware of inferior products imitating our patented heating elements.  STEP Warmfloor™ elements bear special markings and are solely manufactured in the USA.  Unlisted heating elements imitating our patented technology may be a potential fire hazard.  Our certified distributors will stock only genuine STEP Warmfloor™ heating elements.
