We Don't Do Steam

Mostly because the big steam boys in town have the market corralled. There are also very few small, single-family homes that have steam heat in the Bay Area, but every now and then I get a call and the most recent one was last week with a small Crown boiler that was installed in 1995. He didn't have any problems, just wanted it checked out.

I marveled at the equalizer.





8.33 lbs./gal. x 60 min./hr. x 20°ΔT = 10,000 BTU's/hour

Two btu per sq ft for degree difference for a slab

    That's a re-branded Dunkirk. One-pipe or Vapor?

    That Dole main vent has a rather low venting capacity. Unless it's on a very short main, it should be upgraded.
