I'm having difficulties implementing a gas-heated system in the HVAC system part of Open studio. I don't have any experience regarding HVAC system so I would like to ask your help.

What I want is a system consisting of a boiler, delivering heated water to a radiator/CV system in my building and the taps. I implemented the taps, but for some reason the radiator is not taking any power at all. The main consumer of energy is just the pump.

The radiator I'm using is called 'Zone HVAC Baseboard Rad Conv Water' and is connected to the demand part of the loop, just like the taps. image description

You should now be able to upload an image given that you have 10 karma points. Please do (and include a screenshot of your hot water plant loop from OS too).

Also remember in the future to always tag your question with the software you are using if that's relevant (openstudio here)

Thank you, I've added a screenshot of the system.

How confident are you in the plant loop settings? I'm not familiar with 'Zone HVAC Baseboard Rad Conv Water', but many plant operation/consumption issues can be traced back to default plant loop settings. https://unmethours.com/question/17388...

Also, many modelers recommend adding extra adiabatic piping to plant loops.

OpenStudio will add the adiabatic piping to your plant loop. If you add a demand side bypass it adds (or use to add?) an extra one too.
