ᐅ Underfloor Heating Heat Load Calculation – Explained Simply

Good day,

I have read many posts on this topic and have so far understood that room-by-room control (RBC) is no longer necessary nowadays, as it reduces the efficiency of the heat pump.

We have a ground-source heat pump with underfloor heating in all rooms.

The goal is to perform a room-specific heating load calculation so that the temperature is properly set once and never adjusted again.

Our general contractor (GC) now argued that while this is basically correct, once people reach their 60s or older and develop different habits regarding room temperatures, it is not so easy to adjust. Therefore, their suggestion is not to optimize for the highest efficiency right now but to maintain some flexibility through RBC.

I think this argument should not be underestimated. However, I suspect that with the "modern" method of a maximally efficient heating system, this might also be possible.

How would you respond to the GC on this?

Thank you very much and best regards

Do you have a precise source for that? Is the information based on the VOB/C?

Also expressing interest in the source. Our heating engineer wanted to do the heating load calculation as well. But it was just copied from the Energy Saving Ordinance report and then entered into the Vaillant software, so using the extremely low DIN temperatures.

No, since January 1, 2018, it has been stated in the Building Code. Paragraph 650xy
