Here we go. Pic one of my duct outlet ready for the back seat which you can see in pic 2. So the idea is that the air goes out of the heat exchanger up to the eyeball vent.

That can be open or closed. Especially if closed the air moves along the back of the seat cavity and then down the seat to underneath into the front duct system. Simple eh?

Pic 3 is while I’m gluing on some click bonds and later a floating nut plate to hold the heating system to the wall. I think I’ll have some pics in the next log or so.
