Costs for the heating & sanitary trade

Do I understand correctly that he does the rough installation when the interior plaster is already finished on the wall? So he knocks the walls open again? And somehow smears them closed again? Does he have a side job as a plasterer? Wattndattn??? That’s nonsense and afterwards you have poorly plastered walls.

What I found interesting about it was that he does the planning beforehand, but only goes in once the interior plaster is done. Then he installs everything, connects everything, and closes up the walls again. That sounded to us, who build through individual contracts, like coordination with as few interfaces as possible.

Hi,
I imagine that to be interesting with underfloor heating...
Best regards, Olli

Oh, I have already experienced construction projects where the underfloor heating was later milled in the new building. So there is actually nothing that doesn’t exist.

In my eyes, the approach is completely pointless, but the client decides, since he is the one who pays.

So update from me: I received an offer from a system provider with intermediary activity: about 49,000 EUR for air-water heat pump + ventilation from Wolf, underfloor heating and rough installation including assembly and planning excluding sanitary ceramics. A bit at the upper end for me, but with the option of doing some work myself. However, I still need the list of which partial works should cost how much. Actually, I only trust myself to lay the insulation and heating coils, which probably won't be much cheaper...

Schuppdiwupp, here it is already. 2300 EUR for installing underfloor heating including edge insulation strips and insulation and just under 2500 EUR for the sub-insulation. So a total of just under 5 TEUR. That could definitely be worthwhile. The question is, how difficult is something like this and what are the consequences of mistakes?

I personally would stay away from it. However, the cost framework seems quite OK when you look at the values of the [BAFA-Förderung].

Maybe you can try to renegotiate the position underfloor heating from the heating circuit distributor + the insulation very intensively, with the risk that the subsidized part of the heating system becomes more expensive?

Maybe it can be resolved with the keyword "[Bafa]" then?
