<p>HEAT SUMP SYSTEM FOR BUILDING STRUCTURES A heat sump system for building structures in which side walls form a space for fill material, preferably of a granular nature such as sand, and a thermal insulating material is disposed between the fill material and the earth to prevent the escape of heat generated in the fill material normally generated by an electrical heating cable. An insulating material may be disposed around the periphery of the fill material along the side walls around the building foundation. The insulating material is also preferably impervious to moisture to prevent the transfer of moisture from the earth and the side walls to the fill material. While the electrical heating cable, which may be disposed throughout a major portion of the fill material on a horizontal plane, is preferably embedded in the fill material, it may be disposed between the fill material and a concrete slab disposed thereon, or disposed in the concrete slab. 1.</p> |
