ᐅ The underfloor heating in one room is not turning on.

Hello everyone,

The underfloor heating in the children's room does not turn on when we switch it on. However, it has turned on by itself two or three times. We have no idea why.

In the bedroom, the heating is usually running at full power and only very rarely turns off – here, too, we don’t know why.

Do you have any idea what might be causing this? The rooms do not seem to be mixed up. We have a Vaillant gas boiler. Could the issue be related more to the plumbing side, or could it be something with the electrical system connected to the heating manifold?

Best regards!

Thank you, we will then address that for the living room!

How many heating circuits should there be in the living room? 1 or 2?

Or properly carry out the hydraulic balancing...

That would be my approach as well. Compare the set flow rates with those specified in the documentation. Maybe only half the volume is currently set.

I have a question: how do you (or someone else) notice that an underfloor heating system is not starting or “powering up”? Since it is quite slow to respond, I probably wouldn’t notice it running or not starting at all. For example, in our case, the underfloor heating is inactive in one or two rooms because those rooms have reached the set temperature or are heated indirectly from other rooms.

New floor heating systems need to be run in. So, turn on the heating manifold. Set all thermostats to 30°C (86°F). Wait and observe to ensure all heating circuit valves open. If they do, everything is fine. Now adjust the thermostats to the desired settings—no one seriously wants 30°C (86°F)—and the valves will close a bit again. If they do, everything is working properly. If one does not, call a technician. K.
