You are asking someone to work for free here. We could comment on a drawing you propose, but what you are asking for is complicated and you aren't likely to get an answer without hiring a professional.

An 11,000 square foot radiant floor isn't well suited to DIY design, or design-by-web-forum approaches. It's WAY more than a plumbing project!

Why is the radiant floor even going to be on a heat exchanger? Is this some intermittently heated warehouse or barn floor that will have glycol solution to prevent freeze damage or something?
