Radiant Floor Heating Cable - Measuring Guidelines

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

The heat cable should be installed at a minimum distance of:

1/2 to 1-inch from the underside of a counter, fixed furniture, steps, patio doors, baths, or shower
3-inches from all walls (i.e. a 12x12-foot area (144"x144" = 144 sq. ft.) should be calculated as 138"x138" = 132 sq. ft.)
8-10 inches from toilet wax rings.
8 inches from any other heating system on the floor.

Our worksheet may be helpful for drafting and calculating the square footage of the floor area that you want to install radiant heating. After you download the worksheet, follow these steps:

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.

Subtract the area of the permanent fixtures from the total surface area.

The resulting square footage will be the heatable area of the floor. Select the next smallest system than the calculated are of floor to be heated to allow for a buffer zone that will accommodate any excess heating cable, if necessary.
