Tutoring help for NYS & NYC Master Plumber Exams and All Plumbing Civil Service titles
I've been helping guys and a few gals study and pass their exams as needed for as long as I've been taking Plumbing & Steamfitter, Boiler Inspector exams (38 years).
Math never came natural to me, but I've developed tools 🔧 and study habits that win! I've easily taken over 30 exams over the years and always scored very high...through hard-core study habits & determination 💪
There's been a slew of young men reaching out and I'm tutoring & guiding them as they need it. A few hours here and there to get focused in. A Tune up scrimmage before the Big Day.
I've been in their position, just scraping by and I'm not looking to buy a new boat here! My old, 12 foot rowboat 🚣♂️ on the Reservoir is good enough for me. Here to help you pass. Mad Dog 🐕

Re: Solar Radiant Heat for Airplane Hangar
Aircraft hangers are an almost ideal space for direct, passive, solar heating. I did one, years ago, for a maintenance hangar at an airport in New Hampshire. A specially designed glazed roof with a south facing slope allowed the sun in -- on a sunny day -- which shone on the concrete floor of the hanger. The floor was deep enough so that it stored enough heat to keep the temperature reasonable during the day -- and kept the building warm enough for three or four days without sun. No moving parts. No water (airplanes and water don't get on well).
Re: Solar Radiant Heat for Airplane Hangar
With no storage system heating drops off with solar loss. The slab can hold lots of btu's and the space cooling is delayed some amount of time. There will also be a delay in feeling heat after the sun starts heating panels. It can be a game of how hot can you tolerate at the end of the day so it's not too cold in the mornings. How cold it gets during the no sun cycle and how delayed the heat up cycle is depends on slab thickness, tubing spacing, tubing depth, panel btu output, envelope heat loss, etc. The ratio of collector power to the structures heat loss will determine on average if you overheat or under heat. On a day of low btu input it will get cold and may take a long while to recover. Rational sized storage only covers X hours of structure heat loss. It can make the space consistently more comfortable in the hours outside of sun shine. Storage helps to prevent over heating the space and spreads the days heat harvest of the day. The heat in the tanks can be used to extend heating into the evening/night or can be saved over night to give a free heat shot in the dark of mornings.

Re: Indirect Radiators
I know a couple of foundries still making cast iron boiler sections like this. Would that help you? The connector nipples are - I think - 2" conical. No idea what the EDR is but I could probably find out.


Re: curious if it has been done and how it worked out-replace top portion of brick chimney with SS
As noted, stainless -- or any metal -- will fail in a few decades. One of the chimneys I care for was built of brick in 1780, and I'll grant you that it did need repointing a decade or so ago... but that's all its needed.
Now I'll grant you that it really is brick, and not concrete dyed red... I don't really know how long modern "brick" will last. A century, maybe?

Re: Is there a two pipe steam doctor in the house?
After reading your reply 63-04 you say ,well I doubt I would have risked a 2 inch header , as stated I get beaten all the time by the all 2 inch header installer yeah it’s much cheaper but it ain’t better . As for wanding and cleaning ah yeah chemicals ain’t gonna do it . If piped properly and clean the water line shouldn’t bounce more then 1/2 inch durning the cycle . I would suggest your boss be the one who deals w it he sold it and he did the 2 inch header and should have honestly cleaned after the first steaming and then one or two return visits to ensure it’s clean . It s really part of the job which most shrug off and state that’s the way steam is well I’m here tell ya that ain’t the way it’s suppose to be . It looks from the eq drop that skimming wasn’t gonna happen when you pipe your eq drop in front of the skim port it’s highly unlikely it was in the thought pattern and really over looked . It’s a pet peeve of mine to make sure the skim port can be used other wise it serves zero purpose . The use of the standard boiler drains are crap I usually throw them in my brass scape and install full port ball valve for reverse flushing and removing all the crap the always returns when a new boiler is installed . It isn’t some thing that happens w just about every steam boiler ,multi returns visits to get the system clean,again personally the most common issue w mis behaving steam boiler is bad piping ,not cleaned . This is really the second half of the job and the one most don’t price in until beaten badly then they learn . Just like undersized header and wet steam there common and a lot of system will operate but as I always say never what they should be and the biggest thing the in knowing your successful in your install is when customer never knows weather the heat is on or off they just know that there comfortable . This what we all should aim for being we are all in the indoor comfort business ?
