![]() To obtain a heating effect for snow melting of 100 BTU per hour per square foot with copper tube spaced on 12-inch centers in concrete (or 9-inch centers in blacktop), a maximum of 140 feet of ½-inch tube or 280 feet of ¾-inch tube may be used. The solution temperature entering the snow melting coils should be 120☏ to 130☏. Soft tube facilitates the installation of sinuous coils because of its long lengths and ease of bending which reduce the number of joints to a minimum. ![]() Soft temper copper tube is suitable for both sinuous and grid-type coils hard temper is better for larger grid coils and for mains. Maximum economy is often realized with a combination of sinuous and grid-type coils. The lower pressure loss with a grid configuration permits the use of smaller diameter tube saving material costs. Grids are good for square and rectangular areas sinuous coils are usually preferred for irregular areas. Selection of a sinuous or a grid pattern for a snow-melting system depends largely on the shape, size and installation conditions. In general, installation of snow melting coils is similar to that of floor panel heating coils. Considerable savings can be realized at industrial plant installations where waste heat sources can be utilized. ![]() ![]() To warm the surface, a 50-50 solution of water and antifreeze is circulated through copper tube embedded in the concrete or blacktop. Snow-melting systems, installed in walks, driveways, loading platforms and other paved areas, are an efficient, economical means of snow, sleet and ice removal.
