In 1976, while attending an American Legion Convention at the Bellevue Stratford Hotel, 211 people became ill and 34 of them died from what was thought to be a previously unknown type of bacterial pneumonia.
Some hydronic system designers cling to certain system piping configurations — even when existing projects using those configurations have produced problems.
When troubleshooting a hydronic system, the piping layout is often confusing. To understand the system, I sometimes sketch the piping to help me visualize the flow of water.
Anyone who says they wouldn’t change a thing on the hydronic systems they’ve designed or installed over the last decade is either so oblivious to changes in technology that they don’t know any better, so egotistical they can’t accept that improvement of their work is possible, or so foolish they don’t care what they’re missing out on.
