How to add base-board heaters to hot water loop in OpenStudio [closed]

edit

Hi,

I'm trying to model baseboard heating and am have having trouble adding the heaters to the hot water loop in my HVAC Systems tab. In the Thermal Zones tab I've added "Zone HVAC Baseboard Rad Conv Water" to the zone equipment in each zone, but when I go to the HVAC Systems tab, I can't find the corresponding element anywhere under "my model" or "library" to drag into the loop. What am I missing?

Thanks
