Thermostats out and only flow control?

Hello everyone,

We bought a house (built in 1996) with underfloor heating – in every room except the bathrooms, the bulky thermostats are located directly behind the door. This logically leads to the doors banging against the thermostat and potentially being pried off. Existing damages unfortunately speak for themselves... not to mention that I don’t find those things particularly nice.

Now, we also have the flow control for each floor. As far as I understand the principle, it ensures that each room gets the right amount of water so that everything fits.

Can’t I just remove the thermostats and replace them with something that is permanently open? Then control the amount only with the flow control? We normally set the heating once and that’s it for the winter. I haven’t really found flat thermostats, and even those with external temperature sensors are still quite bulky.

My thermostats are no bigger than a light switch.



If you have a smart heating system, you can control it via the flow rate. However, it is more effort if you want to change something.

There are doorstoppers that prevent anything from hitting the thermostat.

But that is only the sensor and not the controller itself?

In the room there are heads like the Giacomini R470 - directly behind the door, meaning the opening angle is maybe 60 degrees before it hits. Additionally, I have flow regulators per floor and room.

My idea would now be to dismantle the heads in the room. That means all the pins are out, full flow. And then control via the rotary controllers per floor - if smart, one could also centrally control the whole house. The question is whether this could lead to problems somewhere or if I have a flaw in my thinking. There must be some reason why I have two controllers per room. As far as I understand, to ensure that all rooms get the same amount of hot water. But you could test by opening all room controllers fully and then fine-tuning via the floor controller.

That is exactly what people always preach nowadays about heat lamps. You just have to see how the actuators respond. Fail-safe open or closed.

Can’t I just remove the thermostats and replace them with something that is always open?

If you remove it, it stays open continuously. At least that is how it is with me (oventrop).

That is exactly what is always preached today about Wärmelampen.

It should surely mean heat pumps.

But I suspect autocorrect.
