Re: Hot water heater not working after boiler was cleaned
got it fixed, turns out the new circulator was working so I put another one on and flushed the system with 22 psi for about 10 minutes and that did the trick. Thanks for all the help.

You've been dealing with salesmen rather than techs. Where in Westchester County are you located? We might know someone………..

@wwrenchh Im in the Detroit area if you are looking for someone to go over your system and need help.
Re: Corroded connectors on new boiler.
OP the good news is that this is fixable. The bad news is that the company that made this indirect water heater went out of business on the 3rd. (it's not a boiler in your photo, and its a leak on the domestic side, so no boiler water involved with the leak)
It doesn't matter what language the people that made the pipe nipples speak, you can get a leak free connection there. These are generally regarded as good tanks, despite the company going under
Re: Corroded connectors on new boiler.
Leaks at transition fittings is part of the reason I use unions when connecting appliances. Typically, Propress x male or female. Expensive, but they save time if there's a leak and the next guy that has to service the equipment will thank you, even though you may no longer be in this world.
Re: Makeup water causing boiler failure due to thermal shock
My best answer to your question is "NO". (40+ years in the field). I did however one time see an H B Smith 4500 steam boiler lift off it's base, 3"-4" inches when a helper tried to drain that flooded off line and cold boiler. There were 2 other boilers that were carrying the steam load at that time. I would like to say that I remained calm but no, I did not. There was no boiler damage, just a lot of steam hammer.
I have seen quite a few melted cast iron sectional and steel fire tub boilers, and been in the room when 2 units in different boiler plants exploded due to fuel problems. One was an Erie City 20,000 lb/hr high pressure steam water tube boiler and the other was a small cast iron boiler. It is an experience that you never forget.
Re: Setting up the air to fuel ratio High for Low Fire Your thoughts
@Scott Secor at least you got in the kitchen. I had to change in the garage. I can't remember the last time I worked on one or ripped out my last one. They were still running in 1980 but by the 90s I think they were pretty much gone gone, but I wasn't doing much burner work then. When I started in the early 70s everything was mostly #4 oil as far as schools etc. Even small elementary schools were #4 with a 20 gph burner. That gradually changed and the early-mid 80s was just crazy with oil to gas or gas oil conversions.
Re: Identifying Mystery WM Boiler
Before Weil McLain started to archive their discontinued boilers online, (back to the 1960s) there was a series of coal fired boilers that were marketed as oil fired boilers after 1946. You could still purchase the model 57 or 67 boilers as hand fired boilers with the big front doors for the coal shovel to fit into the fire box. But the demand for oil heat was increasing in the late 1940 and through the 1950s. Many manufacturers were not able to retool to make oil fired boilers so they made some modifications so the existing designs were fuel oil compatible. Here is an example of such a boiler with the addition of a vestibule to cover the oil burner and the fire and cleanout doors to give the appearance of a modern 1950’s appliance.
This Weil McLain No.57 boiler was clearly a dry base boiler made to be placed on a base that formed the ash pit for the hand fired models. I would place the manufacturer date between 1940 and 1954. Your barge mounted boiler sections are from the same era and were most likely the next size larger (Perhaps the No. 67)
Re: Makeup water causing boiler failure due to thermal shock
Interesting analogy, have you done any testing ? Maybe she did not do anything too crazy with it.
Re: Heat loss
For existing structure, the quickest and most accurate heat load is from fuel use. Older houses have too many unknows for any Man J type of calculation to be accurate. In case of fuel use about the only error is boiler efficiency, DHW loads and passive solar gains.
The math is pretty straight forward:

If you want even quicker, in zone 5,6, winter fuel use in Therms X 42 is about your heat loss. So if you burn 1000Therms of gas, your heat loss is around 42000BTU.
