The heat pump requires a specific water flow to correctly transfer the produced heating or cooling power.
Too low a flow
It can cause a large temperature difference, reduced efficiency, and low-flow alarms.
Too high a flow
It increases the circulator's consumption and can create noise or balancing problems.
Fan coils and underfloor heating
Each branch must receive the required flow. The total flow is determined by the loads and the desired ΔT.
Circulator adjustment
The selection of constant or variable differential pressure mode should be made according to the system layout and valves.
