Snowmelting, Turfwarming and the Snows of December

It was Thursday, and the groundskeepers were getting the place ready for a game that was, in the minds of most of the locals, bigger than Bunker Hill. Pats vs. Dolphins, and a savage December Nor’easter was churning its way up the coast, which was

Heating in Russia

My buddy, Fred, was over for a visit and the talk turned to steam. Fred works for Consolidated Edison in New York City. Con Ed provides the electricity and steam for about

Washington Steam

I was visiting Washington D. C. with the family. We stayed right near the Smithsonian Institute and spent our days walking through museums and breathing in the history and having a fine time. The sight of the homeless people

What’s the Right Temperature?

My sister-in-law Missy has lived with us for the past seven years. She’ll turn 40 next September and she has Down Syndrome. She often does things that make perfect sense to her, but it takes us a while to recognize

Air Filters

If your house has a warm air heating system there’s a lot you can learn from your hair dryer. It sounds funny, but every now and then we’ll solve a “no-heat” call by telling someone to rearrange

Boiler Sizing

When steam heating was new, back at the turn of the 19th century, coal was the fuel of choice. It burned hot, and it burned long. A good coal-fired boiler would stay lit for eight to 10 hours on a load of coal. Those early boilers contained cast iron grates that were similar to what you

Boiler Failure After Two Years

The boilers (and there were 20 of them) were laying out there in the parking lot, not far from the boiler room door. I could see them as Joe and I drove

Conductive Concrete

Banging Zone Valves

The Air We Breathe

Some Advice for Engineers

I was reading an interesting book titled The Monster Under the Bed (How Business Is Mastering the Opportunity for Knowledge for Profit) by Stan Davis and Jim Botkin (Simon & Schuster, 1994) when I came across something that made me sit up straight and stare out the window for a while.

I know you can’t see this, but . . .

I just got back from an industry symposium where I watched a bunch of engineers give lectures on various topics. Each was an expert who had knowledge to share, and I was hanging on as best I could, not being an

Fire Protection

With the bombing of the world trade center something came to mind that was discussed during my apprenticeship days when the WTC was being built. The topic on the minds of plumbers/steamfitter at that time was how to protect life and property with adequate fire protection as we knew no fire fighting equipment could shoot water up that high

Stormwater Pipe Sizes?

Q) I am in dire need of a plumber who understands storm water drains. I have had news gutters and drains installed (at great expense..for me) but there has not been enough provision made for the amount of water going down. Recent storms last week and on the weekend were disastrous. I need

Is Your Plumber Qualified & Licensed?

What Is Considered Too Hot?

There is a lot of talk about who accepts responsibility when water is too hot. Now, I am curious, what is considered too hot? Many codes do give a minimum temperature of water, either leaving the source or at the point of use
