air cooled heating question

[ROBRIOS]

Hi guys
I have repaired my heating ducts on the 1600 ct camper and through winter and spring it has worked well.

The 2 cables for the heat pod flaps are seized and will be sorted after the summer but for now I can have the flaps set open for hot or closed for cold.

I was wondering where the hot air goes when the flaps are shut in the cold position ?

And is it ok to leave the flaps shut ?

Thanks Rob

If the pods are set for cold the heat just vents out the top of them and is drawn into the airflow under the van. I haven't even got pods on my van at the mo'.
