This is because the circuit in the living room is relatively long or the pipe layout is unreasonable, resulting in greater resistance, so the hot water goes directly through other circuits. After closing half of the valve, it is equivalent to limiting the flow of other circuits, and under the condition that the total flow rate remains unchanged, the flow rate of the living room circuit is directly increased, so it is all hot.

The water circulation is not very good, it is better to put the water and put the cool water out.
To confirm that all the indoor heating valves are open, you need to open the heating venting valves and deflect them one by one to prevent air from inside the heating and causing air resistance.
