Abstract
The disclosed technology includes an integrated system including a space conditioning system, a liquid heating system, and a controller. The space conditioning system can include a refrigerant circuit fluidly connecting a compressor, a first heat exchanger, a second heat exchanger, a third heat exchanger, an expansion valve, and a reversing valve such that refrigerant can flow through the circuit. The liquid heating system can include a liquid heating device and a liquid circuit configured to direct liquid from the liquid heating device through the first heat exchanger. The controller can be in electrical communication with the space conditioning system and the liquid heating system. The controller can be configured to determine a demand of the space conditioning system and the liquid heating system, and in response, output instructions to a plurality of valves to direct the refrigerant through the refrigerant circuit and direct the liquid through the liquid circuit.
