Accurate measurements are the key to a successful and easy installation.
The surface to be heated must be correctly evaluated since the cable cannot be crossed, cut, shortened or modified. Furthermore, the spacing between the cables cannot be altered other than that determined by the gage. A floor plan should be used to determine the actual surface of the area to be heated. Draw the room to be heated and calculate the total surface area. Subtract the area occupied by permanent fixtures such as the bath, counters, work island, etc., all areas that will not be heated.
