Steam velocity kills a heating system

摘要

The call: One of my favorite customers called me about a job we looked at years ago. I like this customer because he loves to talk about history and there is so much about steam heating that involves history. At the time we originally looked at his job, he had installed a boiler that was only half the size required, because the building owner wanted to get a few more years out of the boiler that was already there. The strategy was to replace the older boiler when it died with another boiler of half the size.
