ᐅ Underfloor heating with a brick ceiling?

Hello everyone,
is it possible to operate underfloor heating with a brick slab ceiling without a concrete topping? I have searched a lot online but couldn't find any useful information.
Maybe someone here knows more about this or has experience with it in practice.

Good luck

If the underfloor heating is properly sized, there should be no problems.

Best regards

Hello €uro,
are there potentially any issues with floor heating and furniture like cabinets, and do these need to be pre-dimensioned in advance? Some brick manufacturers also offer a climate ceiling. In that case, you would basically be free in terms of surface area.
It would be interesting to know the advantages and disadvantages of each heating method.

Does this topic also fall within the scope of a certified energy consultant?

Good luck

With a properly sized heating surface, there are generally no problems. Permanently inactive heating areas are accounted for in the overall balance. Temporarily inactive heating zones are piped but their reduced contribution to heating capacity is taken into account accordingly. Additionally, adjustments can be made by selecting appropriate operating parameters.

Climate ceilings are less suitable for heating purposes but better for cooling. For underfloor heating, it is the other way around.

Probably not, unless they are also a building services engineer.

Best regards.

My sister has underfloor heating, and it’s very pleasant to walk barefoot there. The children also enjoy playing on the heated tiles.

That’s what I meant

The concept of “radiation” is a bit tricky. Often, it’s just a marketing term that’s been misused. Every object emits radiation, even if it feels very cold to humans (Stefan-Boltzmann law)! In this sense, radiation from climate ceilings is very relative. Comfort depends greatly on the intensity of radiation, which increases with surface temperature. For efficiency reasons, modern heating systems operate at low system temperatures, and consequently, surface temperatures are also low.
In other words, you don’t really feel anything radiating from these surfaces. It’s quite different with a traditional tiled stove Grandma might have.

Best regards

On the other hand, proponents and designers of clay tile radiant ceilings, such as those used in the Rötzer brick element house, claim that the radiant heat from above mimics what we experience in nature (sunshine = radiation from above). They find this type of heat significantly more comfortable than radiant heat from below (such as underfloor heating). This method is also said to save energy, as a lower room temperature is perceived as warmer compared to conventional heating systems. Whether this is true, however, is for those who have installed a clay tile ceiling heating (and cooling) system in their homes to judge...
