I need help w/ 2 pipe steam radiator

frank_11 Member Posts: 3
I have a customer who wants a sunrad installed, they have 2pipe steam all the rads have top feeds, can I install a sunrad? if so any special way to do it or if not will cast iron baseboard work?


  • Frankie, you can top feed 2-pipe steam

    Steam is lighter than air, and the radiator steam trap is the air vent. No problem top feeding, if the radiator is rated for steam. That's the real question.

    If the radiator has pockets at the bottom that don't drain well, it may not be rated for steam. I don't know about the radiators that you want to use, this is a general rule.
