Abstract
Abstract A system for using solar heat to supplement the heat supplied by a conventional furnace in a house. Solar energy collector panels include conduits for the flow of water, the conduits heating water in a cistern. Heated water from the cistern is pumped through a heat exchanger located in an auxiliary duct communicating with the duct system in the house, the duct system also being connected with the conventional furnace. An air valve is movable between positions closing communication between the auxiliary duct and the duct system, while leaving open the communication between the furnace and the duct system, and opening communication between the auxiliary duct and the duct system, while closing communication between the furnace and the duct, to thereby heat air in the duct system from the furnace or the solar-heated water, respectively.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
151 words
A system for providing solar heat to supplement a conventional furnace hot air building heating system comprising: (a) solar heat collector means for heating a liquid by solar radiation, (b) a furnace for heating air, (c) a supply duct system connected to the furnace to receive heated air therefrom, (d) auxiliary duct means connected to said supply duct system, (e) heat exchange means in said auxiliary duct means, (f) means connecting said heat exchanger means to said solar heat collector means for transfer of heat energy to said heat exchange means from said solar heat collector, and (g) means for alternately closing communication between said auxiliary duct means and said supply duct system and leaving open the communication between said furnace and said supply duct system, and closing communication between said furnace and said supply duct system and leaving open communication between said auxiliary duct means and said supply duct system.
Claim 2
Independent Claim
151 words
A system for providing solar heat to supplement a conventional furnace hot air building heating system comprising: (a) solar heat collector means for heating a liquid by solar radiation, (b) a furnace for heating air, (c) a supply duct system connected to the furnace to receive heated air therefrom, (d) auxiliary duct means connected to said supply duct system, (e) heat exchange means in said auxiliary duct means, (f) means connecting said heat exchanger means to said solar heat collector means for transfer of heat energy to said heat exchange means from said solar heat collector, and (g) means for alternately closing communication between said auxiliary duct means and said supply duct system and leaving open the communication between said furnace and said supply duct system, and closing communication between said furnace and said supply duct system and leaving open communication between said auxiliary duct means and said supply duct system.
Claim 3
Dependent Claim
45 words
The system of claim 1, wherein said last mentioned means comprises gate means alternately movable between a first position closing communication between said supply duct system and said furnace and a second position closing communication between said supply duct system and said auxiliary duct means.
Claim 4
Dependent Claim
48 words
The system of claim 2, wherein said auxiliary duct means is connected in angular relation to a portion of the supply duct means, and pivot support means for said gate means located at the juncture of said auxiliary duct means and said portion of said supply duct means.
Claim 5
Independent Claim
235 words
A system for providing solar heat to supplement a conventional furnace hot air building heating system comprising: (a) solar heat collector means for heating a liquid by solar radiation, (b) a furnace for heating air, (c) a supply duct system connected to the furnace to receive heated air therefrom, (d) auxiliary duct means comprising a pair of ducts on opposite sides of, and connected in angular relation to, a portion of said supply duct means, (e) heat exchange means in said auxiliary duct means, (f) means connecting said heat exchange means to said solar heat collector means for transfer of heat energy to said heat exchange means from said solar heat collector, and (g) a pair of gates, each gate having a size and shape alternately to close off the auxiliary duct means and a portion of said supply duct means at its connection to the furnace, each gate further having pivot support means located at the juncture of said auxiliary duct means and said portion of said supply duct means, said gates being alternately movable between a first position for closing communication between said auxiliary duct means and said supply duct system and leaving open the communication between said furnace and said supply duct system, and a second position for closing communication between said furnace and said supply duct system and leaving open communication between said auxiliary duct means and said supply duct system.
