GG, I'm installing a loading unit to manage storage temp and the big pump to get hot water from near the top of the storage tanks in the boiler barn. Just like the schematics found on the Tarm site. The only thing I've never read was for a forced air system do folks turn the demand pump on and off with the blower. It wasn't intuitive to me if that made sense or the common practice. It apparently is one of those things so painfully obvious it's never discussed.
To all the other kind posters helping me on this topic. Alaska and others mentioned the Grundfos Mega for my high flow and head application. Well you mentioned it was a little pricy..... I fingered maybe $600 or so...... NOT $1900!! Holy moly. Next week I'll start researching
