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.
