FloorHeat STEP Self-Regulating Floor Heating System

Low-Voltage Radiant Heated Floors

Warmzone's FloorHeat STEP is a unique radiant floor heating element. This technologically advanced system features an extremely low profile polyethylene heating element that is flexible and very durable. The self-regulating, semi-conductive polyethylene heating element consistently distributes heat safely and evenly. No other radiant heating element can match its characteristics. Available in rolls 9 or 12-inches in width, FloorHeat is used for in-floor radiant heat applications as well as roof deicing.


FloorHeat STEP system being installed to heat kitchen floor The radiant floor heating system can be discreetly installed under most floor coverings including carpet, hardwood, laminates, ceramic tile, and slate. The electric radiant heat element can even be nailed or stapled in roofing applications without damaging it. The FloorHeat heating element is so thin, making it ideal for heating floors because it will not affect your floor buildup, weight loads, or flooring choices. The radiant heat system's durability and versatility also makes it a popular choice for remodeling jobs and retrofit applications.


When used for heating tile floors, FloorHeat can be installed underneath the cement board so that the floor retains heat longer after the floor heating system is turned off. During installation, no additional mortar or thinset is needed to cover the heating system because it is sandwiched between the subfloor and cement board.


The FloorHeat heated floors and RoofHeat STEP systems provide innovative methods for radiant heating. Utilizing state of the art components and low-voltage electricity, these products are virtually maintenance free and are safe, energy efficient and reliable. FloorHeat has a limited 20-year manufacturer FloorHeat Heated Floors logowarranty and is engineered to provide simple and problem-free solutions. Low-voltage electric radiant heat products have been in use since 1978.

Only the single lead wire needs to be connected to the thermostat, allowing you to layout the entire cable length without having to return the end back to the thermostat.

FloorHeat can be placed closer to the surface than other radiant floor heating systems and requires no surface buildup.

FloorHeat is self-regulating, so it draws only the energy required to maintain the ideal temperature.

Adjustments can be made on the job site, simplifying installation.

FloorHeat is 100% efficient, meaning that all the electrical power is directly transferred to heat.

FloorHeat can be used for a variety of radiant heat applications ranging from snow melting and roof deicing to heating almost any type of floor, including: hardwood, tile, carpet, laminates, vinyl, and marble, etc. It is also ideal for both renovation and new construction jobs.

Particularly advantageous for hardwood floor and heated roof installations.

FloorHeat STEP Floor Heating System Details

FloorHeat is a premier radiant floor heating product. This technologically advanced system features an extremely low profile heating element that is durable and consistently distributes heat safely and evenly. No other radiant heating element can match its characteristics. FloorHeat is a self-regulating semi-conductive polyethylene heating element (available in rolls 9 or 12-inches wide), used for in-floor radiant heat applications as well as roof deicing.


Warmzone's FloorHeat STEP heating element can be installed directly under any material, ranging from hardwood floors to roofing and snow melting applications. FloorHeat is installed directly under various types of floors, and thinset in applied directly over the heating element when installing radiant floor heating under tile. No additional floor buildup is required when heating floors with FloorHeat because it is so thin. The advanced polymer heating element provides safe low-voltage heat and can be used for practically any radiant heat application. The heating element is designed so that it can be safely nailed through (such as in roofing applications), simplifying the installation process.

Heating element distributes heat quickly, evenly and efficiently.

The power unit contains the brains of the system, along with the step down transformer, which converts the line voltage (220 V) to the low voltage (60 V or less). The Transformer is a low-voltage dry type isolation transformer (120 Vac primary and 24 Vac secondary, NEMA 3R enclosure). The Terminal Board is a fused board - 24 Vac with four 5A PTC fuses, set screw lug terminals sized for #14 #4 AWG wires, terminal assignments (one primary hot, four fused secondary hot, and three neutrals).


Thickness and Width: Less than 1/8-inch thick, available in rolls 9 and 12-inches wide.


Material Construction: FloorHeat is a self-regulating semi-conductive polyethylene heating element (available in rolls 9 or 12-inches wide)


Certified Approvals: FloorHeat is one of the safest electric floor heating systems on the market. The system is ETL listed and complies to ANSI/UL-1693 and CAN/CSA-C22.2 no. 217 standards and CE marking. FloorHeat operates on low-voltage and does not require a ground fault interrupter.
