Burnham Megasteam + HTP Superstor Ulta 60 - great combo?
Looking for ballpark pricing on Burnham oil burner MegaSteam (without coil) + HTP SuperStor Ultra 60 indirect installation in 3-family home. What's typical NYC pricing range for this scope?

I'm not a fan of using an indirect with a steam boiler. There is too much corrosion going on with the boiler and piping that it will cause component failures at a much higher rate than usual. You can do HX, wye strainers, etc to help protect the indirect coil but then those devices plug up and fail. I have stopped doing it that way after i had these issues pop up and it also has happened to friends of mine in the industry too. it also could be because i'm up in the northeast where steam boilers get chewed up and spit out by our water.

a superstore uses a cupronickel coil.

I recommend using a steam boiler with a tankless domestic hot water coil. That way, you isolate the steam boiler water from the indirect water heater loop through a heat exchanger arrangement. The wiring can remain essentially the same. You would just need to add a 30 PSI relief valve and an expansion tank on the indirect side of the system, because that portion becomes a closed-loop system heated by the tankless coil in the boiler.
With this setup, the boiler can go cold in the summer when there is no call for domestic hot water or steam heat if you wire the system properly.

@EdTheHeaterMan i was going to recommend that but that's kind of over kill. Why not just feed it directly from the tankless. Cost a lot less than setting it up to work with an indirect. And why use an indirect when you can just use the coil with a storage tank. Or how they use to refer to it as a booster tank lol.

Yeah. Use the tankless as what we used to call a tank heater

Then the boiler stays hot all summer. Even if there is no hot water used, the boiler temperature drops and the burner starts to reheat back up to 160°ish every 3 to 4 hours all day all summer. If you have an indirect, the boiler can get cold and the tank will stay hot for over 15 hours if no hot water is used.. It is all about the stand by loss.
When you are using hot water the burner (or energy source) needs to operate to replace the hot water used. That is a given. Sometimes that burner is wasteful and sometimes it is not. But the stand by loss is where you get killed on a tankless when you need to maintain a higher boiler temperature. Indirect is the best thing since sliced bread, as long as the boiler it is attached to is efficient.

i think they mean feed a storage tank directly from the boiler tankless, a hydrobooster or aquabooster or whatever you want to call it. in practice you use an electric water heater because it is far cheaper than a hot water storage tank.

Then you can allow the boiler to go cold ? I have not encountered that design but I can see how it would work, if designed a little differently than the norm.

people have posted some systems like that before. it uses a non ferrous circulator to heat the tank using the tankless coil.

I don't see much difference between an indirect with boiler water in the coil and a tankless being used to heat a storage tank….except for 1 thing the tankless water connections are small.
You let the boiler go cold with an indirect and I see no need to keep it hot with a tankless heating a tank. Same thing except I would expect a slower recovery

In the summer that would be true. especially if you set your aquastat to 160° for the boiler temperature. In the winter when you have 212° water in the boiler, the recover would be somewhat faster. And I think hot showers in the winter last longer for some reason. Maybe that was because I worked on more oil burners in the winter, and needed to clean my fingernails with a scrubbing brush more.

Bleach mixed with water was the only thing that worked. Then you walked around smelling like bleach.
I guess gloves were not invented back then. #6 oil too.

i probably would have done better in high school biology if they gave us gloves. and a scalpel blade that wasn't from the eisenhower admiration.
