Re: Embasy Onex Condensing Boiler
Gas pressure (static reading, drop at ignition, and if it lights off measure the high lockup when burner shuts down)
can you tell if it lights off at all?
How does the flame sensor look?
pictures please showing gas line, venting etc

Re: Need more consistent domestic hot water
I love the informative views and experiences of you all wrt water heating. The biggest issue, as some mentioned, is how much water a household needs or wants. A 2 person household when they only do a quick shower a day is a candidate for a simple electric wh.
As far as tankless vs tanks, it seems my customers like tankless better than I do!! For instance, my neighbor with 8 children loves his tankless and that one gets USED. As for maintenance, the simplicity of tanks is appealing to me but then there is anodes and failures also. We have seen a fair number of failures with stainless indirects of various manufacturers. We will not put tankless in if a customers' water is ugly and untreated, so most of them I put in see very little scale/dirt buildup even after several years. If you count the hours runtime on a tankless you typically will find they run but a fraction of a boilers' run time, thus they do last.

Re: Need more consistent domestic hot water
Hi @hot_rod , I like to think of it as the plumbing training the people. Tank-type heaters with modest reheat capability teach us that back to back to back showers while washing the dishes will give somebody a cool/cold shower, so we adjust. A tankless unit, sized for multiple uses just delivers, more or less endless hot water. This is the plumbing training us that we can be wasteful. I see endless hot water as needed only in some commercial or industrial applications… It's sorta fun. I'm beginning to sound like one of those old guys, yep!

Re: Is there a way to save this boiler?
wow how thin must burnham be making those castings?
And wow that boiler looks big. Ed’s advice above is very good
Re: Need more consistent domestic hot water
Hi, Thinking is good🤔 Have you considered adding an indirect tank? It would give you more consistent temperatures.
Yours, Larry
Re: Absolute steal for tool collectors
Silver saw SOLD this morning.
Red saw SOLD this evening.
Absolute steal for tool collectors
The silver one is from the 60’s and is in remarkable condition. Runs perfectly!
The red one is from the 70’s and it doesn’t look like it’s ever been used. Also, runs great.
They are both 4 amp saws so there’s not a lot of power there, but when I bought them, it wasn’t for their power. I have 15 amp saws for that.
If you want both, I’ll take $100 each plus shipping.
$125 ea., otherwise plus shipping.
Re: New return line to boiler feed tank, problems?
I guess they will have backed up condensate in the system. I don't understand why the return tapping's in the tank are so small but the installer decided that the pipe need be no larger than the tappings.
The 1 1/4 strainer is probably already plugged.

@Larry Weingarten Never thought having a bunch of kids as an industrial application, but so be it. 🤣
Re: Mouat cleve O vapor trap
@Lou S. ,
I have run a 1926 Mouat system for 32 years. It is a great system.
The 3 ounces they claim in the attached literature is accurate. That is the highest pressure I ever see filling radiators part full even with only one 1/2 NPT vent for the whole system in a remote location. And that is with a boiler big enough that it barely needs to run 50% of the time to heat in design day conditions. Mouat designed the piping such that with part full radiators condensing it wouldn't require more than 3 oz at the header to deliver the steam. It is true. So I quickly found that the standard vaporstat control was essentially useless since there was no logical reason ever to fill radiators more than part full.
Happy to discuss more if you wish.
Also in there is a cutaway view of the return fitting.
