2007 installed Burnham V84, owner wanted to replace it to convert to gas, however while removing the boiler we found the rot starting on the middle sections. It was a good time to do it as next winter it would’ve probably let loose. We went in with a Weil-McLain EG45. The mains are split one side being 1-1/2” and the long main 2-1/2” of course the old near boiler piping left much to be desired. The oil companies were great at servicing and leaving their tags however they never really cleaned this boiler very good as you can see from the pics.
