Boiler Sizing Questions - Steam Sq FT
I have 5 quotes from 5 contractors on my new boiler for my one pipe steam system on my 1929 house. All quoting the same boiler, same supply house. Some charged me to to quote me . It was the first week of May when boiler gave up its life by cracking at the seam.
30 years - would have like longer but still it was a good run. Peerless G-461-W-S 120 BTU, 300 Sqft of Steam and 96 BTU of Output. I live in Grand Rapids, MI
I did a replacement boiler sizing chart walk around myself of my radiators and figured out my heat loss and my total radiation per sq ft.
I came up with 403 sqft of Radiation and total btu h load of 96,672 and a heat loss of 44,803 @ 60 Deg and 52,867 @ 70 - we try to keep day time temp of house at 69/72 because of a 88 year old living in house.
All contractors used the supplier boiler quote of New York CGS-C 50C which has a 354 sqft of steam seems like an potential issue down the road from what I have learned on the site.
I was told not to worry the new boiler could provide the steam needed.
Maybe it can I just don't see how that is so when it is about 40 - 50 sq ft short. Maybe I am not getting it?
