Fan accessory for heater

Apparatus for heating occupied space such as a room within a building and comprising:

• heater means for generating heat, and
• a fan accessory for recovering heated air generated by said heater means, said fan accessory comprising:
• housing means for directing air flow and having an upper wall, a rear wall defining an ambient air inlet, a lower wall defining a heated air inlet, and a front portion defining an air outlet for ambient air and heated air,
• divider wall means extending within said housing means and cooperating therewith so as to define respective upper and lower juxtaposed ambient and heated air passageways isolated from each other for separate flow of heated air and ambient air through said housing means and out of said air outlet,
• said divider wall means being so arranged with said upper wall of said housing that the ambient air passageway is convergingly arranged in the direction of air flow to accelerate the movement of the ambient air passing through said air outlet, and said divider wall means being so arranged relative to said lower wall of said housing means that the heated air passageway is divergingly arranged in the direction of air flow so as to facilitate movement of heated air passing through said air outlet,
• fan means cooperating with said ambient air passageway for inducing ambient air to enter said ambient air inlet and flow through said ambient air passageway and out of said air outlet,
• said divider wall means being so arranged relative to said housing means that the flow of ambient air out of the ambient air passageway causes an aspirating effect on the flow of heated air out of said air outlet by inducing the heated air to more rapidly move through said heated air passageway and to project further away from said housing means to thereby permit blending of the ambient and heated air to take place over a greater distance from said housing means to provide a more efficient operation of the heater means, and
• heater engaging means on said housing means for positioning said housing means on said heater means to receive through said heated air inlet, heated air generated by said heater means.
