Hello,
I am interested to know if any of you are using underfloor heating with a cooling function and have a pipe spacing greater than 10cm (5 inches).
What has your experience been like?
What pipe spacing do you typically use?
I would appreciate your comments.
Best regards

In your opinion, what are the catastrophic consequences of the planning? Apart from the higher supply temperature and thus lower efficiency? Who was this follow-up question addressed to?

@Hausbau55EE as I said, I’m aware of that. It’s miles away from Flow30. Still, investment costs must be included in the calculation. A heating system that is 10% more efficient doesn’t help me if the installation causes additional mid four-digit costs. If you have no flexibility due to your construction contract with the general contractor, that’s unfortunate. Revising the plan towards Flow 30 might cost about 250 euros. Then a larger manifold with more heating circuits and labor and materials for tighter pipe spacing can be obtained from the heating installer at a low cost. Overall, I would estimate costs of a maximum of 1000 to 1500 euros. But the general contractor turns that into 4 or 5 thousand euros.

As for question 1, I seriously wonder, with great concern, how much of the general education common in "my time" must have been lost to even come up with such a plan without realizing what kind of substances inspired those ideas *shakes head*https://www.instagram.com/11antgmxde/

SandyBlack20 Jan 2024 17:57@Hausbau55EE The revision of the planning costs around 750 euros, regardless of the general contractor. But let’s assume the total additional costs are "only" 2,000 euros. It would still take between 10 and 20 years for these extra costs to pay off. And that does not include photovoltaics or the fact that you could invest the 2,000 euros now, which would significantly delay the payback period.
@11ant You mentioned the entire planning process, which also includes heating. Your other statement doesn’t help me much. Can you specifically describe what the catastrophic consequences of the planning are? I am fully aware that the planning has a lot of room for improvement. But this potential for improvement always points toward enabling lower supply temperatures for heating and possibly a somewhat better cooling effect. If you see any other disadvantages caused by this planning, I would appreciate it if you could explain them.

RotorMotor20 Jan 2024 18:09I have seen worse calculations before. The only obvious problem here is the bathroom.
Not just the pipe spacing, but especially the circuit length. Over 100 meters (330 feet) in the bathroom is really not good.
The 150W underperformance is already noted and is probably even higher in reality.
At least split that into two circuits. It only requires one additional valve.
How does it look in the shower/toilet room downstairs? That seems catastrophically short.
