You still need to add an oil boiler interrupt Aqua stat and I think I would go with 1 1/4 main loop, come on up and see what I have, I'll be back Tuesday eve.

Just got back on here. Haven't finished this yet, I have the primary loop already laid out in 1". With my total flow under 7 gpm will it really make a big difference to switch to 1 1/4"? I know the flow would be higher, but I'm barely needing 2gpm on my longest zone and I only have 3 zones. I figure I could always redo it if it was a major issue. It's already gong to be tons better then my old piping from the previous owner of the house. I have some pictures and a couple questions.
I know it's not ideal to have the spiro-vent after the zones as the temperature is lower, but are there any issues that I'll run into because of that? I'm pretty tight on space, and it makes the most sense where it is, right before the primary loop pump seems like a bigger deal than water that is a few degrees higher.
Also in the last picture I have a long leg of copper coming down from the spiro-vent, am I going to have problems putting the expansion tank on the bottom of it with the cold water feed in the top of the tee? I'll have the tank properly supported, but I wasn't sure if there were any fluid dynamics that I needed to consider in the placement of it.
The oil boiler loop and the dhw are set the way they are going as well as the owb hx. I did change it to a vertical arrangement from horizontal as it seems there's less chance of air getting stuck in it this way.

Finally got most of this taken care of. The DHW isn't plumbed in yet and the oil boiler isn't setup except for the loop into the primary loop. I still need to run the oil feed line, venting, and tune the burner as well as wire that in. I've got what I need to have the OWB provide heat and I will have the DHW ready by the time I fire up for the year hopefully. I can take my time on the oil boiler, not really a need for it, just nice to have the backup option if I need to.
