Drawing Request

Danny Morrison

Does anyone have a drawing showing a perimeter heating layout for a 2-pipe low pressure steam system in a multi-story building? Basically, this particular building is a 4 story building with the boilers in the basement. The steam main goes to the attic and runs in a loop around the outer wall with downfeeds to the basement. Of course the retun lines start on the fourth floor. There is a common return line dropping vertically from the 4th floor radiator to the first floor with all radiators on this zone sharing this common return line. It's pretty typical but I didn't have a drawing of it and was wondering if there was a good resource for drawings of this type.

steam system layouts

"the lost art of steam heating" is available here and has drawings of typical layouts, along with much other useful information about steam. any professional considering work on a building heated by steam should have a copy for himself, and another for the client/owner! --nbc
