Construction of a 144 sqm bungalow in Fichtenwalde (near Potsdam)

Just like with us. ;)

Is it any good? What experiences have you had with it?

Any other relevant points?

The supply and the target room temperature

hm... I wouldn't do it. For me, the kitchen unit and the kitchen island were excluded from the FB HZ, or rather, no loops were laid there.

And why should it be better? Because your company implemented it that way? Warm kitchen cabinets are fighting against mold behind the kitchen cabinets. I would know what I would rather choose or which method seems more reliable!

"Warm" kitchen cabinets are fighting against mold behind the kitchen cabinets. I know which one I would rather choose, or which method seems more confident!

Because a couch in front of a wall radiator, for example, is also really crappy.
It’s the same principle.
I also consciously did not install loops under my kitchen block and my L-shaped kitchen.
With 40-50% humidity in winter, there is no significant dew point shift that could lead to mold. That is impossible in a new building with current insulation standards.

The efficiency loss is minimal, and with a VLT of 28° at -15° outside temperature it is also not suitable as a plate warmer, but why should one senselessly install loops there.

Much more important is the design of the even pipe length to the radiator valve, ideally max 80m.
which screed are you getting? Cement or anhydrite?
Anhydrite, i.e. flowing screed, has better thermal conductivity coefficients, but other disadvantages.

Because a couch in front of a wall heater, for example, is also really awful.

Aha! The apples and oranges theory. So you don’t have any heating under your bedroom bed either? 10 kitchen cabinets cover less area than a double bed… The phenomenon of mold behind kitchen cabinets is not uncommon. And honestly: which plumber calculates the saved heating loops?

Thanks for the comparison. I actually do have heating loops under the bed, I think in the end it’s a matter of belief.
The €50 for 50m less pipe and the extra planning effort will be a zero-sum game.

I just wanted to say that basically it doesn’t matter :D
In terms of efficiency, leaving out the kitchen would be slightly better.
Probably saves around €2.5-3 per year ;)

Regarding the bedroom: I would space the heating loops further apart there. Unless you want the same temperature in the bedroom as in the living room.
In the bathroom, install them a bit closer together, but that only has minimal impact (0.5-1°).
It’s important that the shower area also gets underfloor heating.
