Under Stone Heating

STEP Warmfloor heating elements can be used under stone flooring.

Granite, marble, slate, sandstone, and other natural stones conduct heat extremely well which makes them ideal flooring choices for radiant heating. When you picture a dark granite filled room, warmth probably isn’t the first thing to come to mind but with radiant heating you can make your floors feel as beautiful as they look.

Stone Underfloor Heating Installation

STEP Warmfloor under stone allows for unmatched versatility compared to any other radiant heat. STEP Heating elements can be installed directly on top of the subfloor underneath the finished floor or with cement backer board. When using a cement backer board, the STEP Heating elements can be placed either above or below, to best accommodate your conditions or requirements. The most common tile installation methods used with STEP Warmfloor are with cement backer boards, self-leveling compounds or placing the STEP heating elements in double mortar beds. Whether you use a backer board or install the elements directly between the subfloor and the tile, their orientation does not matter. When installing the elements underneath the backer board, make sure to mark the location of the bus braids and the extension wires with a chalk line to be able to see where you can screw.

Due to the high thermal conductivity of tile, the STEP Warmfloor heating elements should be installed with a maximum 3-inch spacing between the elements. Tile conducts the heat vertically from the elements so fast that the heat does not transfer very far laterally within the floor. An element spacing that is larger than 3-inches will have a cold stripe down the center of that spacing. A spacing tighter than 3-inches, even down to 1-inch, is used to provide a very even floor surface temperature and to increase the floor response time to temperature changes in the room.
