Chromalox Roof and Gutter Heating Cable from F.N. Cuthbert Inc.

To calculate the amount of cable needed, multiply roof edge length
to be heat traced by the spacing factor.

The spacing factor (feet of cable required per foot of roof edge) is
determined by the roof overhang, heating width (A) and heating height (B):

Roof Overhang	Heating Width	Heating Height	Spacing Factor
12"	2	18"	2
24"	2	30"	3
36"	2	42"	4

Add the total gutter length and the total downspout length
to the figure calculated above.

Also add enough cable to provide a drip loop prior to going into the box,
typically 6" to 36", to get the total length of cable required.

Determine how many circuits are required. Divide the total length of cable
by the maximum circuit length.

Round that number up (for example, 2.1 to 3)to get the
total number of circuits.
