The heat pump COP on November 12th was approximately 21% lower than that on November 13th, which confirms that heat pump COP decrease as the DHW tank heat storage operation increases. The heat pump condenser generates a higher temperature than that of the HST heat storage for the DHW tank heat storage.

The main difference between cases 1 and 2 is that in Case 1, the extra heat from the heat pump is stored in the storage tank and directly heats the inlet fluid into the heat pump. While in Case 2, the excess heat generated by the heat pump is injected into the ground and partly dissipates into the ground rather than being used to increase the
