  • Heater using hot waste flue gases
    Patent number: 4524910
    Abstract: A method and apparatus to heat a forced-air supply utilizing hot waste gases in a flue. A flue closure housing is supported by a frame that is arranged to surround an opening in the chimney. The housing supports a heat exchanger having side walls formed of plates with a space between the plates being sealed by end walls to form a flow space for a forced-air supply. The heat exchanger is sealed to a flue closure plate forming part of the flue closure housing. The heat exchanger receives a supply of cold air from a motor-driven blower coupled to a header. Heated air from the heat exchanger is directed by a hot-air discharge header through an opening in the flue closure housing.
