How To Install ThermoFloor Heating Mats
This overview does not substitute for a full reading of the Installation Manual.
The below steps will take you from beginning to end simply, but please refer to the full Installation Manual or call us to go over a more detailed installation plan.
Before beginning your installation:
- Ensure that you have a structurally sound subfloor.
- If flooring over an existing vinyl, the existing vinyl must be adhered securely to the subfloor and must be clean.
- Use a 6 mil vapor barrier film if installing on a slab on grade.
1Make sure you have the right amount of material.

- The mats should cover the entire floor space.
- Follow heating mats spacing from walls according to the manual.
- Heating elements should be in areas where you can walk, stand, or want to heat. See your manual for areas to avoid heating.
- Contact support if you have any questions prior to your installation.
2Prepare conduits and electrical boxes for thermostat installation later.

- Complete electrical rough-in.
- This step may be done after cable is laid but is more difficult to do later as location of thermostat may change location of heating system.
3Position and lay out mat, heating element facing up.

- Duct tape ends to each other to remain in place side by side.
- Stickers should be facing towards the ceiling.
4Add underlayment in unheated area to level the floor.

- Underlayment should be laid just like mats and will line up in thickness.
5Position sensors

- Highly recommended to install a backup sensor.
- Position sensor evenly between 2 heating cables.
- Cut out a notch in the bottom of a flooring plank to house sensor, insuring floor stays level.
6Install floating floor on top.

- Consult your flooring manufacturer's instruction manual for details
Note: If you are using a glued down wood floor, consider WarmStep. If you have a specific reason that you are gluing over pad, ThermoFloor is compatible with a glued down wood floor, but in most cases WarmStep is a better option for glued down wood floor.
