Yeah, I see that that is true... it just confuses me.
I'm thinking that their coolant is cooling down, it's just that their 2-3 gallons of coolant in their expansion tank IS enough capacity to act as a buffer for awhile.
So, I expect the 7-gallon tank IS way overkill.
I want to play around with energy storage / getting heat without running the D5 for a couple of hours at a time... so, I would not actively advocate that anybody mimic me. I expect the Rixen numbers do work out a-ok in practice.
