Abstract

A heat transfer system including a thermally insulated tank defining a chamber therein which contains eutetic salt material for retaining high volumes of heat, the chamber inside of the tank is airtight with respect to the atmosphere, a conduit such as a pipe passes through the walls of the tank at two locations to provide a winding within the chamber such that as heated fluid is passed through the conduit, heat is retained by the eutetic salt material within the chamber, a portion of the walls of the tank having protruding sections which extend inward into the eutetic salt solution, the system including a heat sink adapted to be placed in thermal communication with the walls of the protrusions to withdraw heat selectively from the eutetic salt solution, a pump and sump system for recirculating the heated fluid from the conduit through a solar panel for heating and a blower and plenum area for passing air over the heat sink to provide a source of heated air.
