ᐅ Heat Pump Design Software for BLW NEO by Brötje

Hello everyone,

I am considering installing a BLW NEO from Brötje.

Does anyone here perhaps have access to the BLW NEO sizing software from Brötje?

Required house demand excluding domestic hot water (heated separately):

-7°C (19°F) outdoor temperature = 12.5 kW
-10°C (14°F) outdoor temperature = 14 kW

Maybe someone can use the software to calculate the recommended heat pump size for me. Whether a BLW12 would be sufficient or if a BLW18 would be better.

Thanks

House from the 1960s, partially renovated..... How exactly do you expect to calculate anything there? You could take a core sample from each wall and then have the U-value tested in a lab.

I used the statistical heating load calculation method according to Jagnow/Wolff and recorded the averaged values throughout the day.
--> Measuring is still more reliable than calculating.

But I’m not looking to argue with you now. I just wanted the result from the design tool, nothing more.

Building documents and information on how the renovation was carried out are standard procedure.

Alright then...

No problem. However, only the manufacturer, designer, or seller can provide you with the tool and its results.
