As the tank empties, it shows the cold water entering at the lower layers. When water is no longer being drawn from the tank, the heating element in the lower layers is able to heat the cold water. Tank (TL) This example shows how to model a hot water storage tank with temperature variations from top to bottom.
The store can either be a pressurized domestic hot water tank or it can be a non-pressurized tank with an additional separate hot water tank or heat exchanger for the domestic water placed inside or outside the non-pressurized tank.
The geometry of the inlet and outlet for the heat transfer fluid in a hot water storage tank plays a crucial role in both the charging and discharging conditions, as well as in the overall flow distribution within the tank. These factors significantly impact the tank’s thermal efficiency, energy storage capacity, and system performance.

State of the art Hot water energy storage is a mature technology used at large scale in Europe and all over the world. For example, in France one can count for more than 14 million domestic hot water (DHW) tanks running on electricity and about 10 millions on gas.
The stored energy depends on the hot water temperature and on the tank volume. The tank insulation determines the thermal losses and limits the storage period. As presented in the figure, fuel is used to generate hot water. The use of solar energy and heat pumps (HP) are more and more employed to produce hot water with a high efficiency.
