Heat exchanger and vaporizer for a stove flue

摘要

A heat exchanger and vaporizer adapted for mounting on an existing flue for utilizing heat which is otherwise lost and for providing moisture for space heating and conditioning. The heat exchanger and vaporizer includes a central stack for unimpeded transport of flue gases; a casing, with air inlet and outlet, enveloping the stack; a vaporizor contained within the casing for efficient heat transfer and for room conditioning; and a motor-fan unit for producing an airflow through the casing. The vaporizer is in the form of non-corrosive heat conductive helical tubing for maximizing heat transfer in a given volume, for maintenance free use and for convenience in assembly. The vaporizer is provided with a plurality of vapor vents on its upper surface and a pour spout located externally of the casing.
