Hi everyone,

I wonder if any IES user can share what system they are using to model simple electric baseboard heaters?

I tried to add the pre-made "unfanned room heater" provided by IES but the unmet heating load hours are huge (over 2000 hours per year), which makes me think that this may not be the best system to reflect elec bbs in IES, possibly because the system doesn't have a recirculation fan built-in, so I think the heated air is not being properly distributed in the zone which makes the unmet load hours to skyrocket.

Any thoughts on a better system or adjustments I should be aware of?

Thanks, Kaue

Add a direct acting heater to the room units. It can be added to any HVAC system's principal space (small green box).

Thanks! In the direct-acting heater, would the "flux" input in kW be similar to what the electric coil capacity in the baseboards is?

Yup, that is going to be the device output.
