ᐅ Cost Difference Between Ceiling Heating and Underfloor Heating

Hello everyone,

After reading quite a bit here in the forum, I finally have a question to ask.
A brief introduction:
We are building a “solid construction house in prefabricated form” – that is, aerated clay walls (Klimapor) with a general contractor. (190m² (2,045 sq ft) living space in Bavaria)
During the selection phase, we decided on a “climate ceiling” – basically a water-based ceiling heating system.
The standard building description includes an underfloor heating system.

Today, we received the price surcharge list:
Almost €16,000 (approx. $17,000) additional cost for the ground floor
Plus about €12,000 (approx. $13,000) extra for the top floor
That adds up to a total surcharge of €28,000 (approx. $30,000) for the climate ceiling compared to underfloor heating.

I have no insight into whether this amount is a realistic surcharge or excessive.
Therefore, my question to the community:
Can anyone help me assess if this price is reasonable?

Best regards and thanks in advance!

Yes, just as you imagine it. The outdoor unit on the flat roof and the necessary number of indoor units distributed throughout the house.

The ceiling is ideal for cooling. Nearly every modern office building is air-conditioned this way nowadays. When heating, you have to make sure the ceiling temperature does not exceed 35°C (95°F). Otherwise, it can cause headaches.
Is he right!!!! But for single-family homes, I personally find it uncomfortable and unnatural. It’s definitely a matter of personal preference, but I would rather advise against it: -> underfloor heating + air conditioning

At least one conventional air conditioning unit is usually needed for dehumidification anyway (otherwise the ceiling cooling system shuts off too early due to condensation). Therefore, I agree with the majority opinion here.
The underfloor heating could also be complemented with concrete core activation.

For the indoor air conditioning units, have a drainage system with a dry trap installed by the plumber from the start, so that the condensate does not have to be pumped out. And of course, plan the drilling and channels for the refrigerant lines in advance.
