This device is a heat capturing, recirculating economizer ventilator, which is sheet metal and is in kit form, to be assembled by the user, for being applied to standing-fireplaces, stoves, and the like. Primarily, it consists of a housing encapsulating a segmented helical configuration surrounding a vertical smooth flue pipe, which automatically forces room ambient air by virtue of a motor driven centrifugal blower, spirally downward on a double path toward and through diffusers, for the purpose of distributing heated air into a space to be heated.
