FloorHeat STEP Low-voltage Floor Heating Systems

The Trusted Solution for Heating Hardwood Floors


FloorHeat STEP features a flexible, homogeneous, low-voltage polymer heating element. The plastic is electrically conductive, and the resistance in the material generates heat. The element is self-regulating which means that when the ambient temperature rises, the electrical resistance increases and the consumption of electricity decreases. For this reason, the element cannot overheat, making FloorHeat STEP an ideal choice for heating hardwood floors. The versatile system is also commonly used for roof deicing applications. The heating element can be nailed or stapled through to facilitate quick and easy installation, and is polypropylene fused during fabrication to achieve water proofing and protect it from alkaline or salt damage.


Heated hardwood floor FloorHeat STEP features a strong, thin, semi-conductive polyethylene heating element that is 3/64-inch (1.2 mm) thick. The flexible floor heating element is available in 9- and 12-inch wide rolls and can be cut to the desired length and field-wired on site. The rugged heating element can also be used to retrofit existing floors with radiant heat. If you can access the floor joists from below, simply staple the element up between the floor joists and then apply Batt insulation to direct all of the heat upwards. Using the FloorHeat STEP system there's no need to tear up existing floors to add luxurious warmth to your home.


FloorHeat is an excellent choice for installation in new construction as well as renovation projects because of the thinness of the material and its ability to be easily customized. The heating element can be cut to fit unique, odd shapes to accomodate any area in the home. Installers can also nail directly through the low-voltage heating element, facilitating the installation process. The heating elements can be cut to size and wired on site. The system is suitable for installation under a variety of surfaces and can be installed throughout the house or only in areas where extra heating is required. (This is the most common application among homeowners.)

Power Requirements

  ●  FloorHeat systems heating a 21 to 300 sq. ft. area require a 240 V. 20 amp breaker

  ●  FloorHeat systems heating a 300 to 740 sq. ft. area require a 240 V. 30 amp breaker

The formula to calculate the maximum element length per fuse (5A) in the terminal board is 24V x 5A / XX W/ft. The formula for the maximum total element length (8A) with two jumped fuses is 24V x 8A / XX W/ft.

The FloorHeat STEP System Includes:

Heated hardwood floor Heating Element - Low-voltage FloorHeat STEP systems utilize a unique semi-conductive polyethylene heating element that can be cut on site and used for a wide variety of indoor and outdoor radiant heat applications, including most flooring materials. FloorHeat is most popular under hardwood floors and carpet. Since FloorHeat is so thin and lightweight it requires very little floor buildup and won't affect your weight loads. It can work in any new construction or remodeling project without compromising your design. The self-regulating properties of the polymer heating element make FloorHeat one of the most efficient floor heating systems on the market.

FloorHeat STEP floor heating system transformer Control Unit / Transformer - Each FloorHeat transformer steps down high voltage to low voltage (60 V or less) and monitors the power and output of the heating element under the floor to ensure safe, optimal performance while controlling a specific section of the floor heating system. The advanced circuitry of the unit regulates the entire system, making the individual control boxes the source for monitoring the power and output to the heating element to ensure safe, FloorHeat STEP Touch floor heating thermostat reliable performance. This system heats your floors evenly to efficiently provide luxurious warmth for your home.

Activation Device - The advanced STEP Touch thermostat is the activation device of choice for the FloorHeat STEP low-voltage floor heating system. The thermostat is beautifully designed for simple two-control functionality for ease of operation and features a 3-digit, auto-dim LED display. The Touch sensor controls are maintenance free and the unit is perfectly suited to work seamlessly with all Warmzone radiant heat systems. The versatile unit works with snow melting, roof deicing, and floor heating systems, and is capable of interfacing with smart home systems. All settings are stored in permanent memory for instant recovery in the event of a power failure (no batteries are needed).
