Hello, I just run my model where I used district heating for floors and water heating as mentioned here And while viewing the results I noticed that the heating consumption/demand is almost the same in summer (and there is actually a pick in July) as shown below: image description

Can anyone explain that to me? Does anyone have an idea about what could be wrong/ what can I do ?

I would appreciate your help,thanks :)

PS: I used the weather file for Stuttgart- Germany

what are your unmet hours like? Try the unmet hours troubleshooting measure on BCL. You need to post more information if you'd like help.

Hi @mdahlhausen sorry but I am new in modelling and simulating and specially while using OS, so I don't know how to check how my unmet hours are like ? or what kind of other information I could share ? Update: I used the unmet hours troubleshooting measure and it worked, now I have results that make sense. Thanks a lot

I am going to bet that since your DHW is also on district heating, that this is 99% DHW usage. This is somewhat reflected in your peak demand chart, which is consistent through the summer and bumps up a smidge in the winter. Look further into results to separate heating from DHW usage.
