Good afternoon, I am trying to install radiant floor on my open studio model. I have placed ''Zone HVAC Baseboard Rad Conv Water'' and I get these errors. Does anyone know if the HVAC system chosen corresponds to radiant floor and how to solve these errors?

Program Version,EnergyPlus, Version 22.2.0-aa78da9668, YMD=2023.04.14 13:07,
** Severe  ** <root>[ZoneHVAC:Baseboard:RadiantConvective:Water][Zone HVAC Baseboard Rad Conv Water] - Missing required property 'inlet_node_name'.
** Severe  ** <root>[ZoneHVAC:Baseboard:RadiantConvective:Water][Zone HVAC Baseboard Rad Conv Water] - Missing required property 'outlet_node_name'.
**  Fatal  ** Errors occurred on processing input file. Preceding condition(s) cause termination.

Sorry for my english Regards, Pablo

Each instance of a ZoneHVAC:Baseboard:RadiantConvective:Water (i.e. radiador de agua caliente?, not radiant floor heating) in an IDF must have both an inlet node (hot water in) and outlet node (tepid water out), in turn linked to a water loop (e.g. linked to a boiler). You're likely after a
- ZoneHVAC:LowTemperatureRadiant:VariableFlow or
- ZoneHVAC:LowTemperatureRadiant:ConstantFlow ... both requiring inlet and outlet nodes as well.

A few of these as OpenStudio classes:
- ZoneHVACBaseboardRadiantConvectiveWater
- ZoneHVACLowTempRadiantVarFlow
- ZoneHVACLowTempRadiantConstFlow

Thank you very much for your reply.

You are absolutely right, I put radiators instead of radiant floor.

I have placed the boiler and the input and output nodes as you have told me but I get the following errors. Could you tell me a way to solve them through open studio without going to an IDF editor?

* Severe * <root>[Branch][Plant Loop 1 Demand Branch 1][components][0] - Missing required property 'component_name'. * Severe * <root>[Branch][Plant Loop 1 Demand Branch 1][components][0] - Missing required property 'component_object_type'.

Julien Marrec recently gave some nice advice for a similar issue. He references a very handy (Ruby-scripted) OpenStudio SDK example of how to set up radiant floor heating, plant loop and heat pump. Follow the logic/sequence, and hopefully fix your issue. Of course, you would need to adapt the solution to your case.
