Hello dear experts,

I have a question:
We are currently building our single-family home. The house is being constructed to KFW 55 standard and under the Bavarian 10,000 houses program (variant 1.6). The building has a calculated value of "maximum heating demand of 10 kWh/m²".

Included in the requirements is:

Underfloor heating with at least 60 mm (2.4 inches) screed

I passed this information on to my screed contractor... They said this is not practical because the heating-up times increase significantly and the energy demand would be higher compared to a thinner screed... Basically the opposite of the intended energy storage benefit.

What do you think about this???

Thanks for your answers.

Best regards and happy holidays!
Christian

I am simply interested in the topic and I am not satisfied until I have at least a basic understanding of it.
