Dan Holohan: Adventures in pumping

The evolution of pumps, circulators and radiant heat.
Dan Holohan
November 30, 2021

I read somewhere that the most prevalent machine in the world is the electric motor. I thought about that for a while and it made sense. Just look around. But then I began to wonder what the second-most prevalent machine in the world is. Turns out it’s the pump! And most pumps are connected to electric motors of one kind or another, so there you go. Throw a rock and you’ll hit a motor. Or a pump. They’re everywhere.

Dan Holohan: The two sides of hydronics

A history lesson on the two profitable sides of hydronic heating.
Dan Holohan
August 11, 2021
Steam-and hot-water heating joined hands a long time ago to make up what we today call “hydronics.” Both systems run on water, and they’ve been around for hundreds of years. The Institute of Boiler and Radiation Manufacturers coined the term hydronics in 1946 to make the science of heating a building with water sound sexy — like “electronics.”

March 10, 2021
Fifty years from now I doubt I will be predicting anything, and yet, hydronic heating, in some form, will hopefully still exist.
