I’ve enjoyed my reading here on the site, so I thought I’d share some pics of my new EGH-95 Steam boiler, installed two weeks ago.
The house is around 4,500 square feet, 2.5 stories with 20 radiators and 850 sq.ft of steam, built in 1896 and from what I can tell, uninsulated. Still, I think there are too many radiators on the ground floor (8!) and last year had the steam feed valves on the largest ones closed with no issues, but it’s a little too late for that at this point.
The chimney was unlined and not really possible to line it, so the boiler vents through a Tjerlund power vent. There is a Saf-Gard lwco, Vxt-120 feeder, Two 3 inch risers that lead to a 4 inch distributor with 4 mains.
Main venting is via 3 Gorton #1s near the boiler at the end of their long runs (50-70 feet) and one small bullet shaped vent that looks way too small to me. This main is also pretty slow to heat.
The reason for the project was an oil to gas conversion. The old boiler (WM Gold Oil with 830 sq ft of steam) worked fine but was 20 years old and the cost of oil was almost $1k per month in winter here in NJ. The old boiler also had some questionable stuff like a single 2inch copper riser and a tankless coil that was nearing end of life at 10 years. Two 50gallon direct vent hot water heaters replaced the tankless coil.
Now that the new boiler is in place, the heating performance hasn’t improved or deteriorated. The rads on the first floor get hot fast, but the second floor has two rads in adjacent rooms that don’t heat up well in a typical 10 min firing time, so I’ll be experimenting with Gorton “D” vents. The third floor rads seem to work well.
Glad I found the site as I’m sure I’ll have questions. Thanks for reading!
