Re: Damaged baseboard fins - Any way to bring back to life?
You can find fin combs at some supply houses or online. This small amount wont make a noticeable difference though.
Re: Compliance with NYC heating laws & resident comfort: send heat all day, or only when code requires?
I do not have the time to took into analysis of TRVs, I think they are in an old computer. Please look into the posting by Holahan. [excuse the misspelling of his name].
Re: Master Venting on Steam Heating Systems
Rest in Peace Frank. We followed your book for decades. Thousands of NYC apartment dwellers can tank you for their warm winters.
Re: Seeking advice, new to boilers, boiler broke over winter
If you have a constant flame monitored by a thermocouple AND a flame sensor in that flame you have created the Error that a flame is present when there should not be scenario.
No point in having two spark gaps when only one flame needs lighting. Think it through better.

Re: Seeking advice, new to boilers, boiler broke over winter
" it isn't all one integrated module and it has a flame rod separate from the high voltage spark output, you could tee both pilots off of the pilot tap on the valve and connect both pilot spark electrodes to the high voltage output, use the flame rod on one pilot for the flame proof on the ignition control and use a thermocouple and this pilot control "
This makes no sense, parallel spark gaps, a thermocouple needs constant heat for proof…

Re: changing Indirect H/W Boiler to Cold start
Yes I do definitely believe that heating up a 400 pound chunk of cast iron plus 10 or so gallons of water in order to then run a circulator and heat exchanger to heat a tank from 120 up to 140 or so is an idea only someone getting a markup could love (and they do seem to really love them!!)
The fact that I have a heat pump water heater is irrelevant—any water heater makes more sense than an indirect. Especially in this case where he told us they rarely even use the boiler. Come on guys, snap out of it 😅
Re: Near boiler piping
WM always had two tappings. Williamson had , two tappings, switched to one tapping for a year or so, and switched back to two tappings
Re: Taco SR506 to Hydrostat 3250 Plus Constant Heat Call
I think you have the expandable sr501 on this sheet. we don't really know which model they have, or exactly how its wired because we have no photo. If it is the standard single zone model I really dont think there is 120 there.

Re: Reusing the Old Chimney When Replacing a Boiler? Dangerous Mistake!
Not much of a detective story when we didn't learn what was the chimney problem…
Re: Opinions on DHW options
I was including HPWH in my discussion. Looking only at the water heater, and assuming a 3.5 efficiency factor, it pencils out to more than 2X the cost to heat via heat pump than NG with my utility costs. And you DON'T run a boiler all summer. It comes on only when the tank temperature is low. You know, like every other tanked water heater on the planet, including HPWH.
