If our heating or electricity consumption turns out to be completely inefficient in the end, I will definitely report honestly here and say, “you were right.”
The objection from the external inspector is legitimate. Actually, the issue isn’t really about the €4000 (about $4,300), as there are very mixed opinions on whether that makes sense or not.
The idea that I should check something myself on site regarding pipe tightness doesn’t make sense to me. We already have enough people in this country with limited knowledge acting like professionals.

@face26
Since I built my old house with radiators and have only been a passive observer during the renovation, I am interested in your perspective or opinion on the topic of underfloor heating, as we will have one in our new house. I would appreciate reading a few key points about it. Since I don’t want to take over the thread, could you maybe send me a private message?

As long as the screed hasn’t been poured, you can still make changes.
Otherwise, you will always reach room temperature; the supply temperature is simply set to 40°C (104°F) if it doesn’t fit.
However, this also means that your electricity costs can quickly double compared to a well-designed system.

That’s meant kindly, and I appreciate the input, but I have already mentioned several times that this is not a standard design with 35°C (95°F) supply temperature. I also attached the relevant contract documents for reference.
Apart from that, in the worst case, we will suffer from efficiency loss, not from insufficient heating, since our system can operate at higher supply temperatures. I could only criticize it if it wasn’t warm enough at 35°C (95°F) supply, since we pay our team to specifically design it that way.

I don’t see anything unusual about the underfloor heating. It’s normal for it to be calculated separately for each building project. Every system manufacturer offers this service to their heating installers.
My comment regarding your system:
A design supply temperature of 35°C (95°F) for new construction is not very ambitious.
Instead of 16x2 mm (5/8 x 1/8 inch) piping, 17x2 mm (11/16 x 1/8 inch) would be better, as it results in lower overall resistance and saves electricity for the circulation pump.
But maybe your system is well planned and runs cost-effectively; it’s hard to judge from here.
You will know for certain once the heating is running and you observe only a few compressor starts per day, whether everything was done correctly.

What went wrong with the kitchen salesman?

Six months after placing our order, our kitchen still hadn’t been ordered... We were still busy with the new build, so I sent him an email and copied the manufacturer. Two weeks later, I received a call from the managing director of the furniture manufacturer: “Mr. Xyz, I’m afraid I have something to tell you...” I immediately interrupted and said, “Let me guess, the kitchen salesman has filed for bankruptcy?” He replied, “Exactly, it’s along those lines. He collected several down payments totaling a large sum but didn’t order any kitchens...”

I quickly ended the call and went to his home around 11:00 p.m.

Let’s just say I didn’t take the legal route... @HilfeHilfe knows about it. I stopped caring about that guy—anyone who scams elderly people should expect some consequences...

The kitchen is now almost fully assembled; the baseboards (waiting for the electrician) and a glass panel are still missing. He wanted his money yesterday, but he will have to wait a few days. The question I have is whether someone who has filed for bankruptcy is even allowed to collect payments from customers. I need to find that out quickly.

The world is already dirty enough; it doesn’t need any more dirt...

A wild “screed” appeared. It’s super effective!
Basically, the previous discussion was already pointless; we only had a short afternoon to go and check the floor heating loops. The plan was to pour the screed directly after completing the underfloor heating, so the day after. We hoped to meet the underfloor heating company and have a look upstairs, but unfortunately, our timing was off—they had already finished when we arrived.
At first, our timing was better. At the moment, for the third time in a row, we’ve arrived and found no one there. Something always happens. It’s as if elves are at work.
When I posted the photos of the floor heating loops, the screed was probably already poured or in the process of being poured.

So we’ll see—the first winter will tell. I remain optimistic. I still have plenty of time to get upset about any poor workmanship if it really turns out to be bad. Complaining beforehand is always bad for the blood pressure.
