People who knew Capt. Montgomery C. Meigs said he was occasionally pompous, but when the job was done to his satisfaction, he said, “This was the most difficult piece of engineering and construction that I have yet to undertake.”

I love all the advances taking place in the world of hydronics, but I’m still seeing plenty of steam systems out there in our older cities, so knowing about dry steam will help you if you’re replacing a steam boiler. The dryer the steam is, the better you’re going to look to your customers.

I began my career in the HVAC business in 1970 as a truck driver for an AC/refrigeration wholesaler. I stayed there just six weeks because my father — who worked for a manufacturers’ rep — told me there was an opening for a clerk at the rep. It paid $110 a week, which was $10 more than I was getting driving the truck. Plus, I’d get to work with him as my boss.

I have heating (plumbing, fire suppression, etc.) shops in New York and New Jersey. This is very much steam country, and we repair and replace steam boilers and systems all week long and have been for decades. All that is fine, but what I find incredibly odd is the polarized perception of the automatic water feeder.

Most hydronic systems have the boiler running up to 180° F with water returning from the system at 160°. This rarely happens in real life, but it’s the traditional way we do things.

I called the plumber because there’s an immediacy to plumbing; and I’m old enough to know that it’s best for me not to touch pipes. To each his own trade.

My iPhone pinged a text: “Hi, Dan. How are you and Marianne, and the family? I’m sorry to bother you. I can’t get my steam heat to go on. I can’t get a plumber to come quickly. I guess they’re busy with the weather. Can I call you later to ask you something about the burner?”

Some years ago, a wholesaler hired me to do a seminar in a New England hotel for about 100 of his contractor customers. After the seminar, the owner of the company invited me and a bunch of his employees out for a nice dinner. There were about 15 of us.

My shop teacher was a wiry man who loved hand tools. We spent a week making a buzzer base. He taught us how to saw, sand and varnish. He introduced me to a Brace & Bit hand drill and went on and on about how this was better than an electric drill. “Can you feel the wood? It’s alive!” he said, and I could.
