Re: Old Galvanized Pipes: Should new fittings be BRASS or STAINLESS?
Es verdad. Don't mess with Local 130. We only allowed limited use of PVC or no hub for drains in the past 5 years.Code in Chicago is brass fittings for transitions between copper and galvanized. I'd go with the lead free brass option.
PEX is not code for potable for multiple occupancy buildings if you're in the city or Cook. Copper or galvanized only.
They actually don't allow PEX but allow galvanized?
Good grief.
I wasn't joking about lead seals for drains in the other thread. If I had to sum up the Chicago Building Code in one line, it'd be "If it's easier or saves time, it's not allowed"

It doesn't sound like failure. It sounds like sabotage. How come no one blames Gremlins anymore?I always blame the gremlins or say the house is haunted 👻. It’s never my fault. LOL

Re: Do old radiators lose efficiency?
It's funny to see this come up. One of the recent energy efficiency rebates for Nicor gas is to replace or descale radiators. This sounds awfully fishy. This comes from the specialists that seem to believe there is only a couple percent decrease in fuel usage when going from a commercial atmospheric 80% thermal efficient boiler to a 83% thermal efficient power burner boiler in a typical single boiler space heating aplication.
Re: Measuring flow in a hydronic system
OP here -- I don't need the balancing function, the gauge would just be for informational purposes. So is something like that available without the balancing valve? They're kind of pricey, that's all.What will you do with that information?
Are you experiencing a problem that needs diagnosing? Or are you just one of those folks that just needs to know stuff. @ethicalpaul is one of our Steam Boiler DIY guys that likes to know stuff. He put Glass Pipes on his steam boiler, just so he can see what is happening inside there. Not because it needs to be there. Not to solve a problem. Just so he knows what all those books are saying is true.
Re: Boiler Issues - dealing with issues
I am in a 2800 sq ft house.An older home? My Colonial is about 2700 and I'm using a 120K input boiler, and that short cycles more than I'd like on anything except very cold days. My house though is fairly modern with 2X6 fiberglass insulated walls and double pane windows in Zone 5.
If your house is older with single pane windows and no wall insulation or in a zone 6 or 7, you'll need more.

Re: Forced air and hydronic in-floor heat
I have had a similar problem and tried a thermostat that had 3 stages for heat and 2 stages of cool. I used a 2 stage gas furnace with a 2 stage condensing unit for my one story home. I could not get the spread far enough apart to keep the furnace from operating when the radiant could do the job but was just a little slow to respond when the outdoor temperature dropped too quickly. After 2 years of adjusting different parameters on the boiler and the thermostat.
I gave up. I finally ended up with a Nest to operate the AC and the Radiant boiler and a separate thermostat for the gas furnace. When the outside temperature was lower than 17°F the radiant could not keep up. When that happens, I just set the radiant to 75°F and set a separate furnace thermostat to 68° or 70° (whatever the girlfriend is comfortable with) until the Outdoor temperature is above 17°. Then I would put it back to normal and the gas furnace would not operate.
You would think that if they can put a man on the moon you could make a thermostat that does what I want it to do.
And Who is THEY anyhow?
