I have often read here that the thermostats are more for decoration than actually used. We currently have underfloor heating as well, but our apartment building is over 20 years old, so I assume the insulation isn’t as effective as it is today. That means we adjust the heating a bit more frequently. However, I can imagine that once it’s properly set up, the heating just runs throughout the winter. But without the thermostats, how does the house determine the current temperature? And how is the underfloor heating controlled at all? Just by the control valves on the heating system? I hope someone can shed some light on this 🙂

So, if I can manage with 20 degrees in the bedroom, do I just reduce the flow there a bit? It’s not quite that simple (trial and error helps), because if 1,000 liters per hour are pumped through the house and 150 liters go through the bedroom, the remaining 850 liters (just right for the desired room temperature in the other rooms) go to the rest of the house.
But if only 100 liters flow through the bedroom—meaning less heat input from the underfloor heating—then 900 liters go through the rest of the house, which may make those rooms somewhat warmer.

fach1werk18 Jan 2022 17:03I occasionally visit someone who controls the heating solely by adjusting the flow rate. During the heating season, I now refuse to sleep there because I freeze my backside off, as the room is otherwise unused. The owner no longer likes to adjust the flow control because it requires very precise tuning, and afterwards, he can’t get it back to the way it was before. If you like that...

This clearly indicates either incorrect operation or simply wrong settings. Or the person might just prefer it cold. I know people like that; they always need a maximum of 16°C (61°F) in the bedroom to feel comfortable. Other factors such as a generally too low heating curve and/or improper hydraulic system setup can also be the cause.

But that doesn’t affect the other controlled values, right?
