2015-12-28 · When thermostatic valves in heating systems close, the volume flow drops. This results in slight pipe resistance. The declining flow rate means that the circulation pump requires a lower pressure head. This is identified by the automatic control of the circulation pump. It automatically adjusts to the system and reduces its performance.

When this path is open, the hot water heater in tandem with the hot water recirculation pump push actual hot water through the pipes. When the actual hot water reaches the valve, the metal expands again causing the path to close. Then the path/valve stays closed until the water cools down too much again, at which point the cycle repeats itself. .
