Re: Hydronic Baseboard Return Tubing Expansion Noise
or consider adding outdoor reset to the system.
The noise you are experiencing is the rapid expansion/contraction of the pipe when it goes from 70F to 180F.
Outdoor reset controllers will modulate the water temp based upon demand and outside air temp and can help in quieting the system down.
It can also save you some fuel costs.

Re: Big Mouth air vent update
I should have Amazon stock shipped later next week. Unless @Phil53 wants to step up to the plate and handle my retail sales.
I'm handling all orders I have on my sheet here at work before I get to any Amazon stock though so if you want one sooner, best to call and get on the list.

Re: ICF house to efficient.
You could simply use a Pioneer w/ a FPHX and a circ for DHW . Basically making your own Versa Flame . Too bad very few realized the value of that unit , we installed several with stellar results .

Re: Very strange boiler problem
You think so? Vent damper motor seems to operate without issues but could the terminals on it be going bad cause of the initial incorrect wiring on the gas valve? Also is a effikal rvgp-ks-6bkf damper.

Re: 1 pipe steam main up and over hallway
>> then drops back down 28" into the next basement space<<
how does the condensate return from the bottom of this down 28"?</blockquote>
I'm thinking - it's probably parallel flow main from there and terminates at the end somewhere into a wet return...

Re: ON/OFF switch for circulators. Allowable? Type to use?
If you trust everyone around to not turn it back on, sure. I'm not always so ...trusting. Probably a character flaw. 
A disconnect within sight is comforting.

Re: ON/OFF switch for circulators. Allowable? Type to use?
...It would be nice to think so. 'tain't true. They will auto adapt, within a remarkably broad range -- but not indefinitely in either direction. Nothing would. With them -- or anything like them -- it is a very good idea indeed to try to come as close to the correct size as you can to begin with, and then let them fine tune.
I see that Grundfos now offers the Alpha2 line of circulators, which feature a so-called "AUTOADAPT mode, will automatically analyze the heating system, find the optimum setting, continue to adjust its operation to changes in demand." This seems like it would handle a problem of a pump being incorrectly sized for the system. ...
Re: Does anyone know why oil in the water
Nice pipe work in progress, Dan
Good to see nice welded pipe in those sizes now and again. I have a pair of 100+ BHP sectional steamers going in soon in that league and am looking forward to it.
The oil issue: The way I see it, the oil creates a surface film through which the steam must release itself. As steam breaks the surface, not only of the water but of the oil, you can imagine the turbulence of incompatible strata. The oil settles back into the void of the released steam bubble, some is trapped between the water and oil layer, even for a moment. Foam is created and holds other impurities which perpetuates the resistance to steam release.
I am sure there is more to it than that, and others probably have better explanations.

Re: Can I upgrade to wifi thermostat with this aquastat?
It's not uncommon for the common side if the low voltage transformer to be connected to the case. A quick test would be to throw a multimeter between the stat terminals (one at a time) to ground, with the thermostat turned off. If you see 24vac between jusst one terminal and ground, that terminal is the hot and the ground can be used as a common for the stat.

Re: I built the wall...............after I knocked it down
So your 2" header doesn't even meet the minimum spec from WM. Using both risers doesn't allow you to downsize the header.
