ᐅ Does it make sense to combine a clay thermal ceiling with underfloor heating?

speerHello everyone,
from what I’ve read online and from brick manufacturers, a brick climate ceiling is considered excellent without reservations. I understand that heat radiated from above is likely more comfortable for people.
I’m interested in how much heat actually reaches the floor compared to a radiant floor heating system. Which building materials are suitable for the floor in this case? Are the supply temperatures the same as those used for radiant floor heating? Besides the floor covering, is anything else like a screed or similar applied on top of the brick ceiling? Does it make sense to combine a brick ceiling with radiant floor heating in certain rooms, for example in a bathroom (women always want warm feet )?
Lots of questions—I would appreciate hearing about any practical experiences.
Best regards

the system temperatures are generally somewhat lower than with underfloor heating at comparable pipe spacing, since the proportion of radiant heat is higher. The lack of convection means even less dust is stirred up by the heating system.
The system responds "faster"—provided it is embedded only in the plaster.
This means the heat reaches the room more quickly.
Concrete core-activated ceiling heating systems do not have an advantage in terms of response speed. After all, another component needs to be activated, such as the screed in underfloor heating.
The floor construction in the rooms remains almost unaffected.
Only the minimum screed thickness can slightly decrease because the minimum coverage of the underfloor heating pipes is no longer required.
Depending on the system, however, the ceiling may involve additional work (plastering).
In my opinion, ceilings are significantly more expensive to install compared to the relatively simple effort involved with precast concrete slab ceilings and underfloor heating as the heating system.
You have flanged fitting connections under the screed of the floor above.
That could potentially cause problems... in any case, this is not necessary with underfloor heating since it is installed continuously from the manifold into the room and back again. So this is initially a disadvantage of the ceiling heating setup...
The brick manufacturers specify the pipe system, which is relatively expensive to connect (especially fittings), and it is recommended to stay "within the system"...
The cooling function works excellently, and it is nice to have a cool house in summer.
However, one should not expect miracles, but while the neighbors’ rooms slowly but surely heat up over the summer weeks, you stay consistently at 23°C (73°F) with activated "passive" or "silent" cooling and effective shading of the windows.
In this case, underfloor heating is the wrong approach... a supply temperature of about 30°C (86°F) still feels "cold" for the spouse’s feet... so don’t confuse this with the "underfloor temperature controls" of the 1990s and earlier.
Because it "radiates only from above," the surface temperatures of the floor are naturally lower than with underfloor heating. We compensated for this at least on the highly heat-conductive tiled floors by also installing underfloor heating there (but with wider pipe spacing).
I have also read that the room air temperature can be about 1 degree lower due to the higher radiant share. However, I cannot confirm that from my own experience.

Hello karliseppel,
some time ago I contacted several chilled ceiling manufacturers to inquire about potential visits and demonstrations of their systems. However, I never received a reply. It would be great to talk to people living with these systems to hear their opinions.
Why did you choose this type of heating, and do you know of any opportunities to see installations in the Stuttgart area?
Best regards and have a nice Sunday
