In last month’s article, we looked deep into the pipes of an old two-pipe gravity circulation system. We will now continue looking at the history and advances of these wonderful mechanical systems.
Piping methodologies for distribution systems — Pt. 2
I came across a single-pipe gravity system that had its piping pitched upward from the gravity heat source, just like the two-pipe system These systems do not like the application of a circulator Even though many of these systems are still functional in delivering excellent comfort to the end users, their overall efficiencies are much less than today’s standards
