ABSTRACT:
Air heating and circulating apparatus adapted to be positioned on the floor of a fireplace to produce heat pumping action without requiring a blower includes a base pipe defining a primary heating chamber and an inlet leg for supplying air thereto, a hot air discharge pipe defining a secondary heating chamber disposed above the primary heating chamber and an outlet leg for discharging heated air into a room, and a plurality of support pipes mounting the hot air discharge pipe above the base pipe and establishing communication between the primary and secondary heating chambers. The hot air discharge pipe is upwardly inclined from the secondary heating chamber to the outlet leg and the support pipes are arranged at an angle to the vertical such that air heated in the primary heating chamber rises in the apparatus to be provided with a horizontal velocity component for discharge through the outlet leg. An electrically operated blower can be used with the apparatus to force air through the inlet leg from the apparatus and increase hot air discharge.
