    I have just ordered this book. I’m fascinated by these stories and glad there is a platform in which people can hear them, I think in order to adapt new procedures you need to know how they originated or maybe we don’t need to change them !!!!!

    I attended the B&G Little Red Schoolhouse in 1992. I just looked back at the pages of notes in my training seminar handbook hoping to find the name Gil Carlson, but the only instructor name I have recording is Bob DeWyze. There were several instructors that week and I do remember an older gentleman at the overhead projector one morning with a constant trail of smoke swirling through the light beam. I'm not sure if Mr. Carlson kept doing the seminars after retirement but I can see his strong presence in all of the training materials. I still refer to these notes sometimes to figure out a pumping configuration as I contemplate my own nearing retirement.

    Indeed, he is one of those legends whose name engraved in the heart of the industry forever. I have heard about him via Mr. Holohan articles in the past . His amazing writings have kept me so keen to know about this man . I have been still searching about him where ever the internet leads me .

    Here, when the crew and I have a break time in the projects for drinking tea or stuff like that , some eager clients ask us to talk about the industry revolution . As we have learnt from our overseas friends at Heating Help , we talk about the pioneer of P&S pumping and other breakthroughs in this industry .The issue that There is a point of no pressure change in closed circuit heating system is one of the reasons to remember Mr. Carlson honorably.

    We do thank Mr. Holohan for years of teaching us how this industry is originated and those who have shaped the industry through the engineering path .

    We wish all those departed old timers of this industry to Rest in eternal peace .

    Here's my .02. I think Dan should write an entire book about Gil with lots of pictures, release as a hardcover, charge whatever you need to be profitable, and put it together in the same style as other books in Gil's prime. I'd bet it be a big hit.
