Hello everyone,
We have finally been living in our newly built house for two weeks now. We have underfloor heating throughout the entire house and a digital thermostat in every room. All thermostats are set to 21 degrees Celsius (70°F) throughout the house, and everything works fine overall. As soon as the thermostats reach 22 degrees Celsius (72°F), they switch off—except in the children’s room. There, we have noticed that the temperature easily rises to 23 degrees Celsius (73°F) overnight, and the floor remains constantly warm compared to the other rooms.
I have already contacted the company that installed everything for us, but it will probably take some time before I receive a response. As a curious person, I would really like to understand what could be causing this or what the reason might be.
Best regards

40 or 35° is too high. In the worst case, you should need a 35° supply temperature when it is really cold. The underfloor heating circuits require flow for this: keep the thermostats permanently open. Lower the heating curve until it is no longer too warm, then adjust the circuits. Take your time and don’t change too much at once. Notes help. I can’t contribute anything regarding the settings for Vaillant.
Example of a heating curve in a new build: 24° supply temperature at 10° outside temperature, 30° supply temperature at -14°. According to your statement, the heating curve should be set to 0.2.

You will need to work on that to find what suits your situation.

Yes, it can be that low. I already explained to you what you need to do. Why don’t you just do it? Because I currently live in the house with my wife and a 2-year-old child, and I don’t want to just start adjusting the heating system. With your method, the temperature could easily reach 25°C (77°F) at night, which is probably not ideal for sleeping.
That’s why I’m gathering all the information and carefully looking at what exactly each adjustment does. I prefer to be well informed before I change anything.
What I’m still wondering is whether it makes sense to limit the temperature to a maximum of 35°C (95°F)?
