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.
Re: Mixing a hot water loop with one-pipe steam
good idea, poor execution. you just take hot water out of the boiler and put it back in with some convenient tapings, the closely spaced tees thing wouldn't work. you can circulate boiler water directly in the hot water loop but you need to have the circulator below the water line and can't have auto air vents. you need a bypass to bypass a little return water in to the circulator so it is a bit cooler and doesn't cavitate. it will work better with a 3 piece circulator than a wet rotor because of the muck that tends to be in steam boiler water.
you could isolate it by using a tankless coil in the boiler. if you use a heat exchanger a shell and tube or small indirect will work better than a brazed plate hx.

Re: Am I blind? Not seeing the gas shut-off valve.
No gauge in the boiler. That is the one provided by NTI. There are digital readouts of all the parameters but that does not qualify as the gauge required by code. So, you get that piece of junk to pass inspection. I don't believe it is necessary if you know how to work the menu of the control. But not all customers are that well versed in reading the 100+ page manual to get to the menu that tells you the way to get that info. the pressure reading from the electronic menu may not stay there and drop to a default menu after several minutes of no input to the control. The age of modern computers that make out life easier. Don't you love the 21st Century?
Re: Hot Water Boiler Rattling at Start of Heating Season
That's what's so frustrating. I played the video for one of their techs the second time they were here, and that's when he said it might be the solenoid in the regulator rattling, but he wasn't sure and said wait until something breaks. At this point I'm ready to use a different company just to get it resolved.

Re: New Energy Kinetics Boiler: Was Kettling, Now its a Water Hammer Issue
We still need to check it. In the first two pics above, we can see a nozzle container sitting on top of the boiler. The end cap on it is blue- which is the color Delavan used for solid nozzles. Hollow nozzle containers have red end caps.
Re: Very Old Two Pipe Radiator
Is there a name on the base? If it's a Bundy, it would be "A.A. Griffing".
