The heat gain from external sources does not decrease when the thermostats are closed. The underfloor heating, especially in new buildings, is so slow to respond that the sun or whatever else no longer shines long before an effect triggered by closing the thermostat occurs.
In addition, there is the self-regulating effect: if the room is overheated, it may already be as warm as the underfloor heating itself. Physically, heat no longer flows from the underfloor heating into the room. The lower the supply temperature, the more pronounced this effect is. In extreme cases, the underfloor heating even absorbs heat from the room. This is only meant as an example; in practice, the self-regulating effect is hardly relevant due to the aforementioned inertia.
Excluding external heat sources: without thermostats, it only works if the hydraulic balancing is done in the first winter and the heating curve is adjusted accordingly to suit the house.
