DHW first always then the furnace. You can get a little warm air out of 120 degree water, you won’t be getting any hot water from it though. DHW is the biggest although temporary load you have, biggest load first then the next lower load which would be the furnace HX.

I would agree. You won't like fluctuating shower temps but slightly changing air temps while using hot water is no big deal.

It'll heat either way but I try to pump into the side where the air exits. This makes the hottest air. Pumping in the bottom purges the air out the easiest tho.
Which brings me to another suggestion, especially if you push down through the hot air coil, plumb in a fill valve at the water heater and use it to blast the air out of the coil and lines. Otherwise it can take a bit to purge out using the pump on the stove.

Like Eldon said, you want the air leaving to see the hottest water last( incoming water). Air shouldn’t be to much of an issue to purge out by closing the return water valve at the boiler for 2-3 seconds while the pump is running and then quickly opening it. You repeat this until you don’t hear any more air bubbling back to the boiler.

I think I think about air purging more than most. Probably because we have such rough terrain and the stove can sometimes be much lower than a high point somewhere in the piping. Then air gets "hung" in the high spot.
Anyway, just a side note.

What do you think of the Rhinoflex? I have a couple rolls of it on order but haven't seen any in person yet.
