    Yes but hat still owes me $100 for betting my wife wouldn't allow me to paint all of the radiators flat black.

    I think the point has been lost in this post. I'm not saying upsizing is "BS", nor am I asking for praise. The "no love" comment was meant to be comical. I love searching the wall at the end of the day for install pics, so I was excited to post mine at the end of a long day. I repiped the existing piping to meet manufacturers specifications (and beyond), as is what I proposed for this particular project. The boiler is now piped and working correctly. There are still improvements to be made, and they will be made. Here's a 3" header on and IN6 I installed, just for you @Hatterasguy

    Doubling the pipe size is poor workmanship according to Starbucks books on steam heating. I will post the page tonight on this thread.

    Let JoeS and Dave and Ezzy know. I'm sure they will be very interested.

    BTW, "doubling" is the based upon the volume, not the diameter. But, you already knew that.
    Based on a 3" having a surface area of 7 inches and a 2" having the surface area of 3.14 inches, I'm betting he did know that.

    A 3" is double the volume of a 2".

    I am not sure. He may be saying 4" instead of 2".

    I need to teach you guys about the trombone header.

    I suppose that might make this a French Horn Header.
    That's a church organ header!

    @Paul S. The gsa 75 Will give you 19.22 fps @ 1 psi when piped with a single 2" boiler riser and 2" header.

    @Hatterasguy - That kind of approach works great on a 16 penny nail. Not so much with people. Ask me how I know that.

    Depends on the pressure. I find this helpful (they also have a mobile app.)

    Try looking at different pressures (even negative ones) and see how it affects velocity.
