Hello forum members...
I'm reaching out here because we are somewhat desperate.
We purchased a new build at a fixed price with a detailed scope of work.
Our plot requires that the local utility company supplies the heating system, which we have to rent from them, etc. It’s inconvenient, but that’s how it is. This means that in the purchase contract, the heating system was excluded. So far, so good.
The part concerning the underfloor heating remains and will be installed. Unfortunately, in the section about the heating system that was removed, there is a crucial sentence that the builder’s installer is now referring to. It says, "The heating system will be connected with supply and return lines to the heating circuit manifolds. After the installation of the heating system and connection to the heating circuit manifolds, the underfloor heating will be filled."
The utility company does not do this. The installer now says that this is no longer covered by the house purchase and is sending us an additional cost offer.
This amount now totals 4,160€ (roughly $4,400). I just can’t believe this and am looking for expert opinions to tell me if this is a problem we have to accept and if the prices are realistic or not...
Thank you very much in advance...!
1 unit Flushing and initial filling of the heating system according to VDI 2035 – 340€
1 unit Drainage connections for floor drain and funnel trap – 187.33€
1 unit Additional heating for screed drying – 992.00€
1 unit Additional expansion vessel according to DIN EN 13831 – 154.00€
1 unit Connection of underfloor heating made of corrosion-resistant material including diffusion-tight insulation – 931.35€
1 unit Heating circuit pump group for supply of the underfloor heating and connection to the existing buffer tank – 891.47€

The question is why the hot box is necessary. In theory, heating could also be done via the district heating system. And nearly 1000 euros rental fee is quite a lot.The price is reasonable; the device needs to be connected to the underfloor heating system, have water refilled, electricity connected, and then everything has to be taken apart again.
Why... depends on the planned heating system. Possibly it is not yet installed for screed drying, which would be the simplest reason.

The price is fine. The unit needs to be connected to the underfloor heating system, refilled with water, connected to electricity, and then everything needs to be restored afterward.Connecting a device like this Hotboy isn’t rocket science and can easily be done within an hour. It’s understandable that the heating technician doesn’t just set it up for free. And they don’t have to.
If you calculate carefully and assume the installer charges €200 for setup and takedown, you still have nearly €800 left for the rental fee.
Malle Zwabber4 May 2023 21:04I understand that already;)
But usually, during the construction phase when the drying process is running, a temporary power distribution box is still on site.

Malle Zwabber4 May 2023 21:12You don’t seriously believe that the heating engineer included the costs for the electrician in the calculation. The guys can’t even reliably estimate a heat pump ready for operation. 😉

They don’t even manage to properly calculate a heat pump ready for operation. 😉The original poster is generally corresponding with a general contractor and is now directly in contact with the heating installer. They should probably ask if there will be additional costs for the connection, yes.
