Piping - will this work?

Mark Walnicki

Okay, I did the best I could with the picture in mspaint. I hope it looks okay and most of it is self-explanatory. Here's a few other specifics: Where the H,C, & M are on the drawing is supposed to represent the three way mixing valve. The piping from the boiler to the 3-way mixing valve is 3/4" copper, about 100' total for supply & return. Radiant loop is hooked to the mix port. 280' 1/2" pex suspended tube in the radiant zone. Taco 007 circ.

Obviously things are left out for clarity, and I'm not wondering about control strategies yet, for now just wondering if things would flow as they're supposed to, if it were piped like this. Thanks.
