Primary and secondary circuit: how the two circulators work together

In a system with hydraulic separation, there are usually two circulators: one on the generation side and one on the consumption side.

Primary circulator

Ensures the required flow through the heat pump.

Secondary circulator

Adjusts the flow to the needs of the zones and terminals.

Important

The two flow rates do not always have to be the same, but their difference affects the temperatures inside the separator.
