There good restaurants,bad ones and great ones. Do the the ingredients make a difference? Absolutely,but the main difference is the chef!  The choice of boiler between one triple pass and another is barely worth discussing!

Agreed

you can't go wrong with either one, unless it's improperly installed. Both are first-class units.

bypass of p/s piping

i picked the biasi boiler, its comming monday, along with circs and a aq251 controll should i do p/s or a bypass to keep the return temp up? is a bypass just a tee from the s to the r with a ball balve?

thanks
