Hello, Vitaliy!

In your case, it is better to connect the underfloor heating circuits to a separate collector equipped with its own centrifugal pump. Do not forget to install a coarse filter and a check valve in front of it (in the direction of the coolant).

To adjust the temperature of the liquid, the system is equipped with a mixing unit or a temperature regulator that controls the operation of the pump. If it is necessary to adjust the temperature of the heated floor in all rooms, then each circuit is equipped with a separate mixing system using a two-way valve.
