Re: A discussion about wet steam to not hijack anyone's thread
Laddie, we deal with these issues and many others all the time. A little wandering in the weeds isn't going to interfere with that, and if you don't care for it, you don't have to read it.
You have a problem with your system just ask.
Re: Is this the way they're going in now?
ISTR Smith has never specified if or how welded headers should be installed. But whoever did that work clearly doesn't know steam.
Re: Pushed off till 2028, but still here
What does that have to do with the statement? there are residential heat pumps that can produce 77% of listed capacity at -30f ambient, add on that maine is not forcing you to ditch your gas heating system you can keep it as a backup and I fail to see why anyone would take issue with a heat pump that someone in maine decided they want to install. I think reading @jesmed1 comment the mention of maine seems to be less of an endorsement of installing heat pumps in maine and more of an example of how a state has adopted more heat pumps without a strict mandate forcing everyone to swap them out.
"So Maybe Maine has figured out a reasonable system that other states could learn from." - This seems like a totally reasonable statement.
EDIT: OK so you edited your original comment to add in gibberish, speculation and politics. no need to continue with this one. I always assume the heat pump threads are thinly veiled politics discussions but come on lol

Re: Cool little tool for verifying circ pump rotation ?
Just so you know it does not indicate the pump or impeller is actually spinning, or rotation direction.
Mainly it tells you there is power at the pump, demo at link.

Re: Is Steam Heat still a Viable Option?
Boiling the water uses a lot more energy than pumping it.
This is faulty logic. The energy is indeed required to boil the water, but then the energy is in the steam. That energy is released when the steam changes back to water in the radiator when it releases its heat.
So this argument is incorrect.
What you CAN argue is that typical residential steam boilers are only about 83% efficient, in that about 17% of the energy goes up the chimney in the form of heat that is wasted. High efficiency boilers can get to what, about 95% in optimal conditions?
But they cost more to install, way way more to maintain, and they fail a lot sooner (given proper maintenance on all boilers involved) than a cast iron boiler.
Steam has its difficulties, mostly in terms of balance, and definitely in terms of finding good contractors, but it is not inherently less efficient.
Re: Replacement Hydronic system, cost of installation
I understand completely, have edited my posts, and ate the burger which was delicious.
Instead of cheddar used with Roquefort which bumped up the cost to . . . well, never mind.
Also, I just donated 21.99 to the website and only ask that Erin gets a proper burger for having to put up with this nonsense.
Have a great day.

Re: Boiler still leaks after changing out relief valve, Expansion Tank, Regulator, Air Vent....
Right off the top of my head I suspect the coil in the indirect water heater has a hole allowing domestic water pressure at perhaps 60psi to pass into the the boiler side which should be around 12psi. You can test this by closing the cold water to the water heater for some amount of time. You can hasten this by draining a bit of water out of the boiler to lower the pressure to about 12psi and see if it climbs or leave it and see if the dripping stops when the pressure get to a tad below 30.

Re: Cracked bonnet nut
One quick try could be a properly sized hose clamp around the nut to keep it together. I have done this in a pinch.

Re: Ever use an off brand press tool?
They also make a Slushie Machine for those warm, opressing days!
