Maybe this will untangle your mental knot: The heating system supplies ALL your rooms with the same warm water. Your room thermostats can switch the flow through the heating coils in a room on/off. The lower you set the number, the earlier "off". 6 means "always open".

It logically follows that you should set your heating system as suggested by Mycraft in #10. Everywhere set to 6, after warming up measure the temperature everywhere. Ideally, 6 gives you the comfort temperature in the warmest room (bathroom?). Then adjust the rest using the room thermostats.

If following this procedure the bathroom is too warm or too cold at 6, the heating system must be readjusted.

Does that help?

Yes, that is now explained very well and I think I have understood it now. That's how I will proceed! Thank you very much! :-)

Yes, that's true, because it often makes no sense with low-temperature heating systems like underfloor heating.



Not really, the temperatures are similar but a difference of 3-4 degrees is possible and most need nothing else.

And how do you want to manage the difference if everywhere everything runs for the same length of time?

When planning the underfloor heating by the spacing of the heating loops. Tighter in the bathroom, wider in the bedroom. This results in a warmer bathroom and a cooler bedroom with full flow in both rooms without any thermostats.

If not planned this way, then with thermostats. But design it so that as many thermostats as possible are set to "permanently open" (in your case 6) (making them effectively superfluous).

The laying distance can no longer be changed now, and we have to assume that it is OK. What still needs to be changed is the flow rate.

You still seem not to have dealt with the hydraulic balancing. This changes the flow for each heating circuit or room. The heating system sends water of the same temperature into each room, but with different flow rates, so the bathroom receives more equally warm water than the bedrooms. As a result, ideally, you have all the thermostats constantly set to "heat" and still different room temperatures.

Finding this ideal setting is very difficult and a lengthy process. With the emergency brake function of the room thermostats, you can more easily achieve the desired temperatures, but this is not the most efficient way.
