A Beautiful Burnham Install by Gerry Gill & Co.
A while back I started a thread on the subject of atmospheric boilers and the problems that most of them have, of rotting out at the water line if the water conditions are poor.
In that thread, there we comparisons made of different patterns of pinning on the sections and the fact that HB Smith's commercial atmospheric model was designed with no pinning above the water line. Shortly after the date of the post, it appears the Smith dropped that model from production.
Here is a link to that thread. http://www.heatinghelp.com/forum-thread/135698/Rotting-at-the-water-line-New-thread-from-Another-Rotted-Out-Steamer-Replaced
And here is a link to the thread that that inspired the thread above. http://www.heatinghelp.com/forum-thread/138040/Still-another-rotted-out-atmospheric-gas-steamer
On my recent visit to Gerry Gill's website, where I often go to look and enjoy his beautiful steamer installations, I found a new install of a Burnham 5 Series boiler. Here is a link to that part of his website, http://www.gwgillplumbingandheating.com/webapp/GetPage?pid=624&thumbpage=1
I couldn't help but notice that the pinning on this Burnham model is all at or below the water line. See image http://www.gwgillplumbingandheating.com/wahelper/GetImage?id=107652
Gerry, I was wondering of you would care to comment about this beautiful installation.
What happened to the previous boiler?
What were the factors that you looked at in installing this model?
Have you installed many of this model?
How would you rate this boiler in terms of reliability?
It looks like you have it set up for 2 stage firing. Is that for precise pressure control since it is installed on a Mouat system?
Again, I have to say this was a beautiful installation!
