Most accumulator tanks don't seem to have the connections required to tap into the full output of a higher capacity furnace. 

Here is what I would like my ideal tank to have:

Why not build one?

I may have to.   :(

Who would you suggest using for the coil exchangers?

I would not have any idea, how about speaking with a local supply house and see what is available, I would bet that a good solar thermal supplier could help, we have a heavily subsidized company in Maine called Efficiency Maine that sells Marathon tanks for their solar thermal installs, perhaps you could start there.

Something with that many coils will have to be made and open storage in EPDM liner. There are pics of one on hearth. Most I'm aware of commercially available have 3 coils. Look at the http://varmebaronen.com/aqualux-teknik-accumulators/ (http://varmebaronen.com/aqualux-teknik-accumulators/)  if you haven't already. Coils get expensive fast and proper sizing if fabricating yourself.

Man Europe seems to be so much more ahead of the game than the US.  This sucks.   :-\

Yes they are, in several countries it's illegal to idle wood boilers. And why the big top brands like Viessmann , Kob, Effecta and others are designed for batch burning then shut down. No idle ing, as this is where they are the most inefficient and emit particulate. Everything uses storage, fire it once a day or two and done. Some will calculate how much wood to put in to top off storage, or as in chip or pellet boilers it's all automatic.
