TGA planner difficulties, underfloor heating supply temperature + wastewater ventilation

Alternatively install the chicken ladder electrically.

What speaks against not connecting the chicken ladder to the heat pump from the outset instead of operating it electrically?

A chicken ladder with a 25-degree incline is simply useless and only introduces rust into the floor heating system!

With the TE, the flow temperature is fixed at 35 degrees, or have I missed something by now?

He is now at 36°. But at a correspondingly low temperature. It should actually be lower during the year, shouldn't it?

It is now at 36°. But only at a correspondingly low temperature. During the year it should actually be lower, right?

That is the design temperature... if it is 8 degrees outside temperature now, then the flow temperature is only 26 degrees. (Arbitrarily chosen number, should just be an example). That is then the heating curve where you can see that.

Exactly, that's how I understood it too.
