Women can work in mechanical rooms

Subdural’s triumph
Dan Holohan
October 2, 2023

Another photo appeared and this one had a woman in it. She was holding a long wrench and the business end was attached to one of the risers to the boiler’s drop-header.

Dan Holohan: Why Congress has no windows

The history behind the U.S. Capitol building.
Dan Holohan
March 2, 2023

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.”

Dan Holohan: Dry steam is the goal

Things to consider when replacing a steam boiler.
Dan Holohan
February 1, 2023

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.

Dan Holohan: That seventies show

Learn from the mistakes of the past or we’ll be doomed to repeat them.
Dan Holohan
January 4, 2023

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.

Dan Holohan: The geography of auto-feeders on steam

Auto-feeders — yay or nay?
Dan Holohan
December 1, 2022

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.

Dan Holohan: Why we use 180 degrees for hot-water systems

The history of The Carbon Club.
Dan Holohan
November 2, 2022

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.

Dan Holohan: Frozen steam coils

Think like steam.
Dan Holohan
March 2, 2022

Frozen steam coils always seem to happen at the worst of times, don’t they? You’re busy because it’s cold enough to freeze coils. The place with the frozen coil contains people who are doing things that are so important they can’t possibly be without that particular coil. Not even for a minute. They’re on the phone, and they’re not being reasonable.

Dan Holohan: The case for radiator covers

Common sense isn’t always that common.
Dan Holohan
January 3, 2022

In March 2010, a nine-month-old boy rolled off his sister’s bed in Jersey City, New Jersey, and got stuck between the bed and a cast-iron, steam radiator that was as hot as it’s supposed to be. The radiator delivered third-degree burns to the infant and left him with permanent scars.

Dan Holohan: Does size matter?

Big or small, contractors do it all.
Dan Holohan
December 2, 2021

A young guy who was about the size of Bruno Mars came to my seminar once, and we were chatting during a break. I asked him how long he had been in the business. It’s good to see young people getting involved.
