From an energy point of view, to increase the TES tank volume provided energy benefits in all cases. The ability of MPC to run the heat pump during high-performance hours made the heating system more efficient, since the COP increased, while the on-time consumption supplied by the heat pump was reduced.

If the tank is too small, its storage capacity is small and it will be unable to accumulate all the plant surplus solar energy (Q ‾ C / Q ‾ excess less than one). By contrast, if it is overdimensioned, it will store this energy ( Q ‾ C / Q ‾ excess close to one), but it will not be using all its height, since there is not enough energy to charge it completely.
