Hi everyone!

I am making a building model in DesignBuilder with underfloor heating system with boiler as the heat source for the hot water. I have set the plant loop volume to "Autocalculate," but the Performance Summary indicates that the "plant loop volume" is too small (0.020103 m³)

What variables or inputs should I check in EnergyPlus or DesignBuilder to identify the reason for the small plant loop volume?

@fransmich what simulation tool are you using? Please mention it in the title or body of your post, as well as add a tag so that others can provide better help.

Thank you for reminding, Aaron. I made the model using DesignBuilder and possibly to modify the inputs using EnergyPlus Editor
