Re: Steam sight glass
The steam mains have water in them all the time. Why would this specifically rott them but all of the condensate not?

Re: New Energy Kinetics Boiler: Was Kettling, Now its a Water Hammer Issue
Thank you for all your comments. Sometimes flux and other contaminants can make their way back to the boiler and make it kettle as you describe. I think the acid flush will clear things up. I do see that it is a Press job, so that means it is likely something left from the system prior to install that flushed back when the heating zones opened. @CTYankee , do you know if they used the 8-Way boiler treatment that comes with the boiler? That will usually prevent kettling and keep the boiler cleaner.
Best,

Re: Boiler Replacement Sizing Question
the boiler piping looks pretty good, changing it isn't going to do anything for you. make sure you have good venting at the end of the mains.

Re: Boiler Replacement Sizing Question
The savings that would be even slightly more than negligible would only happen during the once a day during recovery from setback and even then would be tiny compared to the cost of replacement so it would never pay for the replacement cost. just do it right when it does need to be replaced.
since you commented on someone else's year old post, can you show us your near boiler piping? If your near boiler piping is as bad as the piping from the op and it affects the speed with which the system heats then fixing it could be worth it.

Re: Boiler Replacement Sizing Question
"With the system as it is, I do observe cycling on pressure (2-2.5psi), but generally only when recovering from overnight setbacks of around 4 degrees or more."
If it only cycles coming out of setback downsizing will do nothing. I would spend the money on something else. JMHO
Re: Mixing a hot water loop with one-pipe steam
Here are several ideas of what you want to do
Re: Mixing a hot water loop with one-pipe steam
here is all the info you could ever need. I added two hot water radiant floor loops to my steam boiler with these instructions and I’m just a homeowner
Re: Steam sight glass
oil on the water, improper near boiler piping. it may just need skimming. how long did the installer spend skimming it? show some pictures of the boiler and piping from several feet back.

Re: Mixing a hot water loop with one-pipe steam
Every once in a while some scheme for using the heat in the condensate comes up — and yours is a rather good one, as they go. Problem is… there is verry little heat to be had. Nothing like enough to heat even a very short loop.
As @mattmia2 says there, the best approach — and there are a number of ways to execute it — is to pipe a hot water loop directly off the boiler.
