ᐅ What installation spacing should be used for radiant floor cooling?

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

The spacing is calculated based on the room-specific heating load. In our case, values range between 15 and 7.5cm (6 and 3 inches) spacing. Just as important is the length of the circuits and whether walls are also covered.

We have the room-by-room heating load calculation, which in most rooms specifies a spacing of 15 cm (6 inches). However, I have read from one manufacturer of underfloor heating that for underfloor cooling, the pipe spacing should not exceed 10 cm (4 inches) – especially not with wooden floors. On the other hand, our manufacturer says that our spacing is not a problem at all and that they have already designed systems with 20 cm (8 inches) pipe spacing for underfloor cooling, which also worked. Therefore, we are uncertain.

Hello,
15cm (6 inches) does not sound very ambitious. What supply temperature is planned for NAT in that case?

It’s not very ambitious. Our general contractor bases everything on 35 degrees. With additional costs in the four-digit range, it’s not financially worthwhile to aim for 30 degrees.
I am specifically concerned about the cooling function and whether it could be problematic due to the 15cm (6 inches) installation spacing.

It may be necessary, but not always. It depends on the overall design. Maybe you want to show the plans?
