ABSTRACT:
A heat-saving attachment in the nature of a jacket surrounding the smoke pipe of a furnace located in a basement or other relatively unheated space. Air is drawn from the unheated space or other area into the annular space between the jacket and smoke pipe, absorbing heat from the exterior of the pipe as it is directed through laterally disposed baffle means within the annular space from whence it is directed through a warm air duct to a space to be heated. Electrical controls may be provided to establish predetermined time delays between turning on and off of the furnace burner and respective on and off controls of an intake fan for drawing air from the unheated space into the jacket.
