Iron Piping near boiler on High effieciency

What is the general consensus on piping say a triangle tube solo in iron pipe.  Basically up the pumps and flow controls and then from that point on would be copper.  I haven't seen any done like this.  I like iron pipe because it is very sturdy and minimized dissimilar metals near boiler (not entirely since the exchanger on a TT solo is Stainless steel).  I also noticed that the Cascade setup is made of iron pipe (a53) I think.

Curious for others opinions and experience.

    I like it for the same reasons. Plus, I don't want the torch heat getting too close to the boiler and controls.

    Black iron or ProPress

    on the small ones.  Aquatherm on the big jobs.

    with a Vitodens, it's more work than propress that's for sure.

    Black pipe flows more than it's equivalent size in copper.

    Screw Pipe

    This is a Munchkin I did for my cousin, never installed a TT. You gotta love the screw pipe
