Since topics about hydraulic balancing are coming up more frequently again (including for me), I believe I’ve found a pretty good tool that helps you get an overview of your system (also useful for forum members who want to actively assist with balancing). The required inputs are quite straightforward (I supplemented them in my case), so it might help others in the future as well. The origin of the Excel file can be seen in the JPEG (unfortunately, I couldn’t upload it as a PDF) since I’m not sure if I’m allowed to link it directly. Feedback is, of course, welcome.
P.S. The diagram isn’t 100% accurate for my situation as I only have one heating circuit manifold (because it’s a bungalow), but it couldn’t be displayed differently.
