Nofoss...,

I continue to look at your design and was wondering about the location of the pump for the loads. Why not put the pump in the return side?

Also, why have a small expansion tank on the sources when you have one on the storage?

Thanks for the help

The pump could just as well be on the return side - makes no difference. I like to have multiple expansion tanks in case one or more components (such as storage) have to be isolated. It's not a requirement., but I think of subsystems that are self-contained.
 
For the reasons stated by Nofossil I actually have three expansion tanks. I have two to accomodate my storage tanks and one small one mounted on my primary loop. I have my system plumbed in such a way that I can run without the storage if I wanted to. In this case my storage expansion tanks are essentially cut-off from the system and my small tank is there to take care of the boiler and primary loop. Seems to work pretty well...
