Use the following tips to calculate the square footage of the heated area:


  • The heated area of the room should exclude areas beneath counters, fixed furniture, or any other areas where Nuheat cannot be installed under.

Tips to calculate square footage:

  • Square footage is calculated by multiplying the length (in feet) by the width (in feet) of an area.
  • Triangles are squares/rectangles split diagonally in half. To calculate the square footage of a triangle, multiply the length (in feet) by the width (in feet) of the triangle and divide by two.
  • If needed, break up the heated area into smaller squares, rectangles, and/or triangles to help calculate the square footage of the entire area. Calculate the square footage of each individual area and add the square footages together.
Calculate Square Footage

Area A = 3′ x 4′= 12 sq ft
Area B = 4′ x 5′= 20 sq ft
Area C = 2′ x 2′ ÷ 2=  2 sq ft
Total 34 sq ft
