House Pictures Chat Corner - Show off your house pictures!

Since I built my old house back then with radiators and am currently only active as a silent observer during the renovation, I am interested in your perspective or standpoint on the topic of underfloor heating, as we will have one in the new house. I would be glad to read a few, but important key points about it. Since I don’t want to hijack the thread, could you maybe send it to me via private message?

If our heating or electricity consumption is complete rubbish in the end, I will definitely report honestly here and say "you were right". The idea that I should check something myself on the construction site regarding pipe tightness makes no sense to me. We already have enough people in this country with half-knowledge acting like professionals.

As long as the screed is not laid, you can still change something. Otherwise, you will always reach room temperature; the flow temperature will just be set to 40 degrees if it doesn’t fit. But that also means that you quickly end up with double the electricity costs compared to a good design.

It is meant kindly and I am also grateful for the input, but I have already mentioned several times before that it is not a standard design with 35° flow temperature. I’ve also attached the relevant contract documents.
Aside from that, in the worst case, we will die an efficiency death, not a cold death, since our system can also manage higher flow temperatures. However, I could criticize that if it didn’t get warm enough for us with 35° flow, as we pay people to specifically design it for that.

I don’t see anything special about the underfloor heating. That it is calculated separately for every construction project is also nothing special. Every system manufacturer offers that to their heating installer.
My comment on your system.
A flow temperature of 35° as the design temperature for a new building is not very ambitious.
Instead of 16x2, a 17x2 pipe would be nicer; you have a lower total resistance and save electricity for the heating circuit pump.
But maybe your system is well planned and runs cost-effectively, that can’t be judged from here.
At the latest, when the heating runs and you have few compressor starts per day, you will know if everything was done correctly.

what went wrong with the kitchen salesman?

6 months after our order, our kitchen still hadn’t been ordered... we were still busy with the new construction, so I wrote him an email and put the manufacturer in CC... 2 weeks later I got a call from the managing director of the furniture manufacturer: Mr. Xyz, unfortunately I have something to tell you... I interrupted him immediately and said; let me guess, the kitchen salesman filed for insolvency... he: exactly, it’s heading in that direction, he collected several deposits in a large sum and did not order any kitchens...

I quickly ended the call and went to his home (around 11:00 PM)

Let’s just say, I didn’t take the legal route... knows about it. I didn’t care about this guy anymore, anyone who cheats elderly people has to expect an upcoming penalty...

The kitchen is now almost fully assembled, the baseboards (waiting for the electrician) and a glass panel are missing, he wanted his money yesterday, but he’ll have to wait a few days, the question I ask myself is, if he filed for insolvency, whether he is allowed to collect payments from customers, I have to quickly find out.

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

As long as the screed is not laid yet, you can still change something. Otherwise, you will always reach the room temperature by setting the flow temperature to 40 degrees if it doesn't fit. But that also means you can quickly end up with double the electricity costs compared to a good design.

A wild "Estrich" appeared. It's super effective!
Basically, the discussion before was already pointless, we only had a short time one afternoon to go look at the floor snakes. The planning was that the screed would come directly after the underfloor heating was completed, so one day later. We had hoped to still meet the underfloor heating company and also to be able to take a look upstairs, but unfortunately our timing was bad, they were already finished when we arrived.
At first, our timing was better, right now for the third time in a row, on the day we drove there, we didn’t find anyone. Something always happens. It’s as if little elves were at work.
When I posted the photos of the floor snakes, the screed was probably already poured or being poured.

So we will see, the first winter will show. I remain optimistic anyway. I still have enough time to get upset about botched work if there really is any. If I do that beforehand, it’s always bad for my blood pressure.

I'm keeping my fingers crossed that everything works out
