I would even go as far as to say that the maximum temperature they reach is about the same as the connected heating circuit valve.

I don’t understand how there can be a review in the main thread praising the parts for staying closed without power.

Maybe the people always have them off :-D

@Dennis89 It looks like a Logafix heating circuit distributor by Buderus. There are datasheets available online for this. However, you can clearly see that your heating technician was just “too lazy” to install or purchase the flow indicators.

I correct myself, it seems that it can actually be bought like this. But I would be very surprised if on your heating circuit distributor you don’t just need to unscrew a blanking plug to retrofit the flow indicators.

PS: Sorry for the formatting, I’m too lazy to figure out how to fix it after copy & paste 😉
Thank you! Assuming I retrofit the flow indicators, do I then adjust the flow rate at the actuators or at the flow indicators?

@OWLer why didn’t you choose fail-safe open instead?

Since building with a general contractor is not a matter of personal preference, it is well known that you have to put considerable effort into convincing others to accept an external heating load calculation.

In the world of buffer tanks and ERRs, this is quite understandable.
However, if you don’t trust this system, it doesn’t make sense.
In that case, you either don’t install these devices at all or you remove them ;-)

I find this very practical for automatically, for example, turning off the cooling in the bathroom during summer and heating the bedroom little or not at all in winter.
