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.

A homeowner posted a question on The Wall at HeatingHelp.com about a drumroll sound that was coming from his brand-new steam boiler. What could it be? He included a video so all could hear, and sure enough, it sounded like a snare drum.

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.

How’s that for a title? I’ll give you the answer right up front: Everyone!  And the best part is you don’t have to know what you’re doing; you just have to show up.

Contractor Thinking About Heating System
Heating Help

Dan Holohan: What's inside?

This one goes back a bunch of years. The contractor was a good steam man, but he had run out of ideas with this job. It was a typical, five-story, New York City tenement building. Its one-pipe steam system had served generations of tenants for more than 100 years.
