This thread is an ongoing saga of the restoration of the heating system at the Louis P. Best Mansion in Davenport, Iowa. The previous thread on this project is long, too long to continue, but for background it can be read at http://www.heatinghelp.com/forum-thread/131216/The-Best-Heating-System
Ok, the time has finally arrived!! Contracts signed with J.L. Brady and Co. Equipment arrived at the date and time I was told, and the very able, experienced, and cheerful crew set about the project at hand.
From the discussions in the first hour, I am 100% confident that these men, Ben and Jim, know their steam, in fact, they know it quite well. I am impressed to say the least!
The first workday has proceeded quite well! And so far, they have not banished me from the boiler room!! Ha! I have tried to lend a hand on occaision, but mostly I have tried to stay out of their way!
The boiler selected is a Weil-McLain 680, with a Reillo 900 2-stage burner. Below, you can view the first days progress.
You can see that the boiler is being installed in a new location. Actually, it is the old location, where the home's original boiler was placed in 1909. Everything old is new again! Right?
Stay tuned for further updates in this story.
