Mobile home antifreezing system

摘要

An antifreezing system for an exterior water pipe servicing a mobile home wherein the mobile home includes a furnace having a forced hot air passage and a cold air return. The system utilizes a hot air closed circuit, thermally insulated, conduit system surrounding the exterior water pipe wherein one end of the conduit system communicates with the hot air passage, while the other end of the conduit system communicates with the cold air return. In this manner a flow of warm air through the conduit system is produced during furnace operation preventing freezing of the exterior pipes and conserving the energy required for antifreezing purposes.
