Heat pump design software for BLW NEO by Brötje

House from the 60s, partially renovated..... How exactly do you want to calculate anything there? You could make a core drill in each wall and then have the U-value examined in a lab.

I applied the statistical heating load determination according to Jagnow/Wolff and recorded the averaged values over the day.
--> Measuring is still better than calculating.

But I don’t want to argue with you about that now. I actually just wanted the result from the sizing tool, nothing more.

Construction documents + information on how it was renovated. This is routine work.

Well then...

All good. But only the manufacturer / planner / seller will be able to give you the tool and its result.
