A vehicle heat pump system including a thermal loop, an eight-way valve, and a controller is provided. The thermal loop includes a compressor, a first portion, and a second portion. The first portion includes an outside heat exchanger. The second portion includes a cabin heat exchanger. The eight-way valve is downstream of the compressor and has a first position in which refrigerant flows within the portions in a cooling mode and a second position in which refrigerant flows within the portions in a heating mode. The controller switches the eight-way valve between the first and second positions. The outside heat exchanger operates as a condenser in the cooling mode and the eight-way valve directs refrigerant flow from the outside heat exchanger to the cabin heat exchanger.
