ᐅ Setting the underfloor heating – desired temperature preference

nils1985Hello dear forum,
I have the following problem in my new build.
My temperature sensor is turned all the way down.
However, I can’t tolerate the temperature in the living/dining room.
It is 25 degrees Celsius (77°F) here. How can that be?
I have already lowered the desired temperature setting on my boiler, but it doesn’t help.
I have one heating circuit for the kitchen, one for the dining room, and two for the living room. All open to one room. Is it correct or possible that all heating circuits are controlled by a single temperature sensor, or did they forget to install some?
Thank you very much!

Hello,
No, this isn’t really related to the heating curve at first. If it’s set too high, you might have unnecessary costs, but the heating controller should still be able to regulate the heating properly. Checking the heating curve is generally a good idea, though...
When did you move in, and has this problem been there from the start?
What often happens is that the temperature sensors are connected to the wrong valves. For example, if you lower the temperature in the living room, the sensor might actually be controlling the valve for the utility room instead of the living room valve.
Another possibility is that the valves have a “manual override” function. This means they can be set fully open manually to keep heating working if the control system fails. Then, of course, it gets quite warm inside, and the heating system can no longer regulate properly.
Check the heating circuit manifold to see if the living room valve might be in this open position.
Regarding your question: From a non-expert perspective, I’d say you shouldn’t have just one sensor for such a large room. Otherwise, multiple control loops might work against each other. One sensor can actually control 2 to 4 heating circuits. Dividing the living room into several heating circuits is not based on wanting different temperature zones, but rather on the fact that pipe runs shouldn’t exceed certain lengths. Large rooms therefore have 2 to 3 heating circuits.
