Part 4/9:
Contrary to its 40-gallon capacity, this water heater boasts a 53-gallon rated capacity, a design that optimally manages incoming and outgoing water. Cold water is introduced at the bottom of the tank—the dip tube facilitates this—pushing heated water out from the top where it is most needed. This clever design proves beneficial, keeping hot and cold water from mixing until necessary, thanks to the principles of thermal stratification. Hot water, being less dense, rises to the top, maintaining a temperature difference along the tank's vertical column.
