    Abstract: A thermally enhanced heating system and a method for thermally enhancing a HVAC system are provided. The thermally enhanced heating system preferably includes an outdoor HVAC unit and an indoor HVAC unit. The indoor HVAC unit includes a first heat exchanger for transferring heat from a refrigerant, a second heat exchanger for transferring heat from a fuel source, and a third heat exchanger for transferring heat to the refrigerant. The outdoor HVAC unit includes an outdoor heat exchanger for transferring heat from an outdoor air to the refrigerant, a pump configured to circulate the refrigerant, and an ejector configured to combine the refrigerant from the outdoor heat exchanger and the third heat exchanger. Preferably the outdoor HVAC unit is operated to circulate the refrigerant through a first refrigerant circuit and a second refrigerant circuit, and combine refrigerant in the first refrigerant circuit and the second refrigerant circuit.
