A heat storage heat pump heater (HSHPH) incorporated into a heating, ventilation, and air conditioning (HVAC) system that provides heat to maintain the temperature in a compartment (e.g., a cabin of an electric vehicle) during both a heating cycle and defrosting cycle. This HSHPH contains a heat exchanger having an inlet and an outlet located in one or more manifolds and a core that includes one or more refrigerant tubes through which a refrigerant flows and a plurality of fins that extend between the tubes, the one or more refrigerant tubes being in fluid communication with the inlet and the outlet; and a phase change material (PCM) configured to store heat transferred from the refrigerant during a heating cycle and to transfer heat to the refrigerant during a defrosting cycle. The PCM changes phase at a temperature that is greater than or equal to 24° C.
