will be replaceing an older burnham boiler total edr of radiators is 715 sq ft of radiation which is a better fit a wiel eg45 rated for or a burnham IN9 boiler has a baseboard loop and a superstor indirect
with the Burnham and their cast iron push nipples . Not saying the Weil would fail sooner , but when we run across a leaker it's usually at the O rings .0
All o ring leakers I find
have been assembled wrong. I have had no issues with the orings when I have assembled the boilers. I have always been pro iron push nipples but I think the issue with orings is sloppy workmanship not the seal itself. It is the installer not the boiler you pay for.Cost is what you spend , value is what you get.

weil O Rings
Amen, Charlie...well said...with over 300 Weils installed in the last 15 years, never an O Ring issue....consider using an SGO with a Riello gas burner......OK with Weil to do so but check local codes...just like that combo a lot better and wish Weil would UL list and offer it that way.0

Not for the installation described in this thread, but for my own future project,
What would you think of a WM 480 with a Riello 2 stage gas burner. It would be slightly oversized for my application once I install inlet orifices, but would be downfired?
Another option is a Burnham v904 with a powerflame burner, but is oversized. Would also be downfired, and I believe that since combustion air is tightly controlled, efficiency would not be compromised, perhaps improved slightly.
Concerns are the comparison of overall quality and durability of the WM and Burnham, and the relative noise level of the burners. It would seem that the Riello with its accoustic cover would be much quieter, but have not had a first hand comparison.Dave in Quad Cities, America
