Abstract: A forced hot-air gutter thawing system includes a multiple of gutter sections which each include a multiple of molded in hot air flow passages adjacent a liquid passageway. A hot air source such as a conventional hot-air type furnace communicates hot air through a manifold which distributes hot-air through the gutter sections to prevent ice and snow from blocking the liquid passageway. The gutter sections are assembled together through heat staking or other fastening arrangement such that the gutter sections may be combined in a modular manner to provide a gutter system for various dwellings.

Abstract: A materials storage chest system stores and selectively dispenses pipe in response to a controller which selectively limits access thereto. A material dispensing opening prevents access to the chest other than through the controller. A communication system provides for communication between the controller and a remote location to simplify inventory management and alert re-supply operators such that the system will provide adequate material supply.
