ABSTRACT:
By providing a heat exchanging vessel which employs no moving parts and is interposed in the exit flue between the furnace and the chimney, an efficient energy recovery system is achieved which prevents hot air from escaping without any benefit. In the preferred embodiment, the energy saving system of this invention optimizes normal convection currents and air flow paths to eliminate the necessity for any moving parts or electrically driven equipment, as well as incorporating fin members to increase surface areas for heat transfer and heat radiation.
