Measuring Guidelines
Heat

Since you cannot cut any extra cable, it is important to obtain an accurate measurement of the heated areas of each room. There a are few guidelines that should be followed to determine the heated square feet of your project.

The cable should be installed at a minimum distance of:
  • 1/2"-1" from the underside of a counter, fixed furniture, steps, patio doors, baths, or shower
    Heat
  • 3" from all walls - i.e. a 12'x12' area (144"x144" = 144 sq. ft.) should be calculated as 138"x138" = 132 sq. ft.
    Heat
  • 8-10" from toilet wax rings
    Heat
  • 8" from any other heating system on the floor.

Draw to scale the room to be heated (each square equals one square foot). Calculate the total surface area. Calculate the area occupied by permanent fixtures such as counters, baths, commodes, etc.
Heat
Subtract the area of the permanent fixtures from the total surface area.
Heat
The resulting square footage will be the heatable area of the floor. Select the next smallest system than the calculated heating area to allow for a buffer zone that will accommodate any excess cable, if necessary.

If you are uncomfortable with this procedure, please fax us your drawing with accurate dimensions and desired thermostat location. We will calculate your square footage, and advise you of the correct size. This road map will assist you in the installation of your system. Please fax drawings to 801-326-5199 and include a phone number in case we have any questions. Heat
