Abstract:
1. A combined gas-fired forced air furnace and electrical backup power source therefore, said combined gas-fired forced air furnace and electrical backup power source comprising: a gas-fired forced air furnace having a central burner area emitting heat; a gas line adapted to supply a source of fuel to said central burner area; a thermal power chip array including a plurality of thermal power chips that produce electric power directly from heat created from said central burner area; a quantity of pre-conditioned air; an air intake receiving said pre-conditioned air; a variable speed blower receiving said pre-conditioned air and thereafter transmitting a pressurized air output; a heat exchanger receiving and heating said pressurized air output to a desired temperature level; an air output receiving said heated pressurized air output from said heat exchanger and thereafter discharging heated ambient air; a flue gas stack routing waste combustion air therethrough; an alternating current (AC) power source and a direct current (DC) power converter electrically connected to said AC power source; a disconnect switch; and, a transfer relay electrically coupled to said disconnect switch; wherein said transfer relay routes external electrical power to said variable speed blower when said disconnect switch is closed; wherein said transfer relay routes internal electrical power to said variable speed blower when said disconnect switch is open; a voltage regulator electrically coupled to said thermal power chip array; a charge controller receiving voltage from said voltage regulator; a rechargeable battery receiving power from said charge controller; a controller electrically coupled to said transfer relay and thereby controlling operation of said transfer relay; and, an inverter electrically coupled to said rechargeable battery, said rechargeable battery generating a direct voltage input that is routed through said inverter, said inverter producing a 120-volt AC from said direct voltage input from said rechargeable battery, said 120-volt AC being applied to said transfer relay to operate said gas-fired forced air furnace; wherein said thermal power chips produce and direct said voltage to said voltage regulator that conditions and levels an output of said thermal power chips based upon different heat differentials; and, wherein said output from said thermal power chips is routed through said voltage regulator and then to said charge controller and then to said rechargeable battery whereat a stable DC bus level is formed.
