Hi, I have modelled a unit apartment with 190 units in Openstudio which don't have any central HVAC systems. I need to model simple fan (20-60w usual electric desk fan) for summer as well as fan-heater (1500-2400w usual electric fan-heaters) for winters for each unit. I have used "CV unit heater elec" as the heater but as you know it's a fan coil and I am not sure if it can properly simulate fan heaters.

@Graphus 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.

Also, what makes a fan-heater different from a unit heater?

@aaron Thanks for the reply. Well, I thought CV unit heaters are water-based fan coils and the efficiency and energy consumption might be different to a simple fan heater? But I would proceed if they are the same, only I couldn't find a reference for the air flow rate and air pressure of a simple fan heater. Any help? Also, can you please let me know if summer fan can also be modelled in OS and if you can address Airflow and Airpressure for them as well? I need to check Fan impact on thermal comfort.
