Just like hot air, the hottest water in the storage tank rises to the top.
As the hot water rises, cooler water is pushed downward into the tank.
When hot water is used out in the system, the hot water is drawn off the
top of the tank, where the water is always the hottest.
As water is drawn off the top of the tank an
equal amount of cold water is added to the
bottom of the tank.
Hot water from boiler is re-circulated back to the tank and restarts the heating cycle.
A tank temperature sensor/control installed
at the top of the bottom 1/3 of the tank,
determines when additional heat is
required to maintain set point temperature
and controls both the system pump and the boiler.
When heat is required, warm/ mixed water is pumped from the bottom of the tank through the boiler and heated.
