Getting Started

  • Custom Design Layout (provided no charge with quote)
  • Digital Ohm Meter
  • Scissors

Please call WarmlyYours (800) 875-5285 for 24/7 installation and technical support if needed.


Step 1 - Dry Fitting / Cutting and Turning

The first step in your DIY heated floor project is checking that the dimensions on the installation plan match the actual dimensions of the area you'll be working in. If dimensions do not match, call (800) 875-5285 before opening the roll. If the dimensions do match, the next step is to prepare the subfloor so it is clean and free of debris. Perform and record the first ohm test (instructions are included in the detailed installation guide). Use the custom design or Flex Roll sheet to plot your path. Begin closest to the thermostat location and utilize a wire down/mesh up configuration as much as possible. Following the design plan, cut the fiberglass mesh with scissors to create "panels". Position the panels around fixtures using cuts and turns to accommodate the system design layout and proper room coverage. NEVER cut the floor heating system's wires - cut the mesh only.


Step 2 - Floor Heating System Installation

Staple, hot glue, or tape the radiant flooring mat panels and cold leads to the sub floor. Using tape, install the floor sensor six inches into the mat, directly centered between the heating wires. NEVER staple the heating wires or floor sensor wire. Apply a 1/8" layer of acrylic or latex modified thinset mortar or self-leveling cement over top of the mesh. Perform and record the second ohm test following the instructions in your installation guide.


Step 3 - Tile Installation

Allow the first layer of mortar or self-leveling cement to cure before installing the tile. To install the tile, apply a second layer of thinset with a 1/4" square notched trowel. Perform and record the third ohm test.

TIP: Experienced installers may wish to combine steps 2 and 3 by covering the mesh and installing the tile with thinset in one step. A 3/8" square notched trowel is recommended for a one-step installation.

TIP: Clean thinset from between grout joints with a wet rag while installing tile, when thinset is wet, in preparation for the grout installation. NEVER use a utility knife to remove cured thinset from grout joints.


Step 4 - Electrical Connections

The final step in installing your DIY heated floor is wiring it to your home's electrical system. A licensed, certified electrician should wire the system to your home as well as to the thermostat. It can be installed in a double-gang wall box with a single mud ring. Allow proper thinset cure time as recommended by the manufacturer (typically 7-10 days) before powering up the WarmlyYours radiant floor heating system.


With WarmlyYours DIY floor heating systems, you can add a luxurious warmth to your home. Radiant flooring is no longer out of reach; with TempZone™ floor heating systems, you can forget about feeling the chill. If you're not comfortable installing the systems yourself, fear not-contractors and electricians can get the job done for you.
