I don't know if this is potential rambling, I'll try the question.

In terms of user experience, when the buffer is "cold" (lower than the heating temperature), is it not interesting to send the sensors directly to the heated floor (without going through buffer) ?

Quite unpleasant this reaction...Faced with the question of a new member who is not going to understand the history of the forum, I summarize what is written in several different threads;
Is there anything wrong with what I wrote?

He didn't say that, he thanks you somewhere. I can understand that in his place, repeating is tiring.
And so thank you for taking the time to answer me.

No, it's pretty fair...

It's not a new member, just a new nickname... in short... you answered quite correctly, so that's very good!

That, except for language tics, I can't guess.
Ars, Mr. Which one, who were you previously?

Message for Christophe:
Looking back at this photo of your flooded exchangers, I asked myself a question:
Wouldn't this drop in level be voluntary rather than a lack of maintenance?
To make them work in steam condensation mode rather than in water/water mode?
With some advantages:
-no, or at least less clogging of the tubes, the steam is normally "clean"
-a drop, at least on average, in the partial steam pressure in the tank's head, thus limiting the leaks that you have since sealed
-a certainly improved exchange (to be verified, I'm not sure)
What do you think?

I think you are thinking too much...and badly on this one, this would be valid with "high" temperatures but at 30, 40 or even 50°C of water, there is not much in the way of energy in the steam ...and above all the majority would condense on the walls and the slab, therefore enormous losses...

(in short the decline, these are simply losses by evaporation which I have since estimated at 5cm per year...)

What do you think?
