Heating elements are thin (3/64” thick) and flexible, yet rugged and durable. Material is cut to length from rolls and can be nailed, stapled, or taped to the subfloor.


Twenty Year Warranty

All heating elements are covered by a 20-year limited warranty to assure years of trouble-free operation.


How we generate and distribute power for use in our homes, buildings and other properties is undergoing an accelerated new age transformation. Driven by the pursuit of clean energy alternatives and net zero design initiatives, more direct and efficient integration of DC current sources such as solar, wind and other forms of alternative energy are becoming readily available. STEP HEAT is specifically engineered to take advantage of current and future forms of alternative energy

Multiple Powering Options For Any Application

Whether AC or DC current, line or low voltage, STEP HEAT's design flexibility provides multiple powering options depending upon source availability, application, and total load requirements. Sources include alternative energy power such as wind, solar, and hydro as well as storage batteries, generators, and various grid provided line voltages

AC Power Format

Popular for standard grid power, solar/wind net metering and stand-by generator applications, STEP HEAT’s AC transformer power supplies efficiently convert the incoming line voltage (240VAC, 208VAC, or 120VAC) down to 24VAC to power the heating elements.

DC Power Format

Popular for alternative energy applications using a direct DC current source generated by solar, wind, and storage batteries systems, STEP HEAT DC controllers are used to efficiently operate the system.

Powering For A Green Future

The manufacturer of STEP HEAT products, Electro Plastics Inc., is a participating member of the Emerge Alliance (, an open industry association. Made up of industry leading companies, liaisons, and professionals, the Emerge Alliance works toward establishing DC power micro grids and AC/DC integration with renewable energy sources.

LEED Certified Green

STEP HEAT is certified by Greener Product who confirms the product complies with the LEED (Leadership in Energy and Environmental Design), LEED for Homes, and National Association of Home Builder (NAHB) standards. LEED is an internationally recognized green building certification system. Developed by the U.S. Green Building Council (USGBC), LEED provides building owners and operators with a framework for identifying and implementing practical and measurable green building design, construction, operations, and maintenance solutions.

STEP HEAT qualifies for credits in the following LEED categories:

      • Materials and Resources (MR)
      • Location and Transportation (LT)
      • Indoor Environmental Quality (EQ)
      • Integrative Process (IP)

Sustainable Manufacturing

The STEP HEAT element is made of a homogeneous, semi-conductive polymer and consists of up to 80% recycled material with a scrap rate of less than 1% during manufacturing. All materials used in the STEP HEAT system are ecologically safe. Polyethylene is an environmentally friendly product; it does not produce hazardous gases and is biodegradable in



STEP HEAT Installation Overview:

STEP HEAT products are easy to install by laying out the radiant heating elements over the subfloor according to a pre-designed layout and connecting to a low voltage electrical power supply. It was designed with simplicity and the installer in mind. The elements are cut and connected on site to fit the application and area size. STEP HEAT elements can be installed on any stable, clean and non-conductive surface. For even heat distribution, maintain spacing between element strips at 2-3 inches (5-7.5 cm).

STEP HEAT radiant heating systems use a thin (3/64”), flexible flat heating element, which operates on low voltage. These durable, lightweight heating elements can be stapled or nailed to the subfloor and can be cut to length on the job site. The installation requires almost no floor buildup, making it an excellent choice for remodeling and retrofit applications, in addition to new construction.

Once installed, the floor heating system provides a lifetime of comfort. There are no high temperatures, stress, or wear on the material. There is no need for a mechanical room with a boiler, pumps, and valves to maintain. There is no dangerous storage of fuel and gas or risk of electrical shock.


Create a layout that shows where the elements will be placed. Elements should be placed in open areas away from conductive materials, plumbing and fixed fittings. Installation should conform to local building codes, ordinances, and trade practices.


Proper thermal insulation is required for any floor warming or radiant heat system. Without insulation, you will encounter cold patches on the finished floor surface. You will need to have more R-value below the heating elements than above them.


Once a layout has been determined, simply cut the element to the appropriate length, make the electrical connections, and run the extension wires to the power supply and/or optional terminal block. Secure the elements to the subfloor (with approved adhesive, staples, or pegs) and cover according to trade practices.


Design Flexibility and Superior Comfort for Your Clients

STEP HEAT is unlike any other radiant heating system on the market today. The entire 12" wide, self-regulating, semiconductive core allows the entire element to conduct heat, instead of the traditional "heat mat" that relies on small wires or hydronic systems that utilizes tubes of heated water. This creates a more efficient system that requires no maintenance. 

STEP HEAT is easy to design around. Our thin (1.2 mm) element requires minimal floor build up. We eliminate the need for boilers and ductwork as well as unsightly radiators and baseboards. The STEP element can also be used under any flooring type, including hardwood. The use of STEP HEAT can contribute points towards the LEED Credits.
