Re: Advice for replacing a Bell & Gossett 2-1/2" with a Grundfos
if you have a 97% high efficiency boiler, you need to check the pump spec for that also. Some of the high efficiency boilers have high pressure drop heat exchangers and need to be primary secondary piping
Got a pic or brand and model?

Re: CARLIN EZ PRO gas conversion burner question - firing problem.
It needs to be set up properly with a combustion analyzer. Its likely excess air.

sound levels measured in free space may be very different than what is measured installed in a hollow wall in a small room

Re: Water hammer in steam system
Need pictures. Water hammer is usually a pipe pitch problem. The condensate has to be able to drain out somehow,
Re: Compliance with NYC heating laws & resident comfort: send heat all day, or only when code requires?
@dschwarz I agree it will be trial and error. You will probably never get it perfect but holding a more steady temperature will reduce complaints and maybe reduce fuel usage…..no guarantee.
To large of a temp set back can be counterproductive.
Re: Loss of pressure in closed system...
regardless of the diaphragm being rupture and the tank waterlogged the system should still hold pressure, and pressure would increase as it heats.
Unless there is a rust hole in the tank, sir or water cannot get out. Where would it go?
Pressurize the system to 20 psi and observe for a few hours or over night.
It is not always easy finding leaks in radiant systems

Re: Sizing a replacement steam boiler
If you have 305 sq ft of radiation that is all you need to know. Forget about BTUs. The boiler rating plate or spec sheet will show how many sq feet the boiler is rated for you don't need to do any conversions or add the pickup factor that is already done by the boiler mfg.
But your calculation of 305 x 240 x 1.33 is correct.
But just use the sq ft rating it is easier.
For Burnham the Steam Max STMX125 is 125,000 input will do 321 square feet of steam. They also have the Independence, but I would stay away from that one.
I am not a Burnham fan however, but the steam max is supposed to be a good boiler
Single most important thing is to INSIST the installer follows the boiler mFG piping diagram. Don't assume he knows this. You will hear "I have been doing this for 20, 30, 40 years yada yada.
Be careful we get horror stories on here weekly that need to be re installed.
And make sure they install a skim tapping and skim the boiler if needed.
You mentioned Brooklyn so maybe @JohnNY , @EzzyT or @Mad Dog_2 . I don't know if they all work in your area.
Re: Lwco shuts off when boiler overfilled?
Agree with @ethicalpaul
The LWCO should not go dead on a high water level
Re: Sizing a replacement steam boiler
Forget all those other facts. All that matters is the EDR vs the sq. feet of steam. The Peerless 63-03 is the right size for you.
