Re: Why Does So Much Heat Go Up The Chimney?
Then my V-14 must be the exception, Glenn. It still has the original Flair stack damper. The only thing I've had to do to it is add some lube to the gear case. If the boiler runs a bit on a mild morning, then doesn't run all day, it will still be warm in the evening since the damper prevents standby loss. That's efficiency!
Of course, I maintain my boiler properly. I would assume that a stack damper that gets plugged with soot will fail. Mine never does.

Re: Burner technicians -what’s going on in this industry?
I think they're both the same, people doing installs that haven't done service is how you get things like condensate lines or gas pipes keeping access panels from being removed for stuff or control wiring that has to be disconnected to move the control board off to the side to pull the blower out or oil burners that won't hinge open because something is in the way.

Re: Burner technicians -what’s going on in this industry?
This happens with av techs and installers. the techs are scheduled for more jobs than they can pay attention to and the schedulers don't understand that there is a couple hours involved in parking on our campus and moving tools and equipment in and out not to mention there is a huge mental load in all that so by the time they are in front of the equipment they are out of time and are thinking about logistics rather than the problem. Then they have been scheduled to do that 2 more times on other campuses 2 hours apart in the same day.
Install crews have a lot of the same logistic problems so they probably get 3-4 hours of actual work on our campus in a day but they aren't scheduled that way.

Re: Question about gas valve placement on the main inside a house, allowed or not?
I don't see how dot would have jurisdiction over fixed, installed gas infrastructure. There is federal jurisdiction to some extent because the state systems are interconnected but it isn't under dot.
NYC needs the level of regulation it has because of the number of landlords that don't care if their tenants blow up and it takes a couple other large buildings with it, you don't see that level of regulation other places unless they have similar conditions. Some states don't let homeowners touch gas. things like this shouldn't happen. I heard this 9 miles away inside my house.

Re: Best Solution for Connecting Copper to Iron Boiler
Galvanic corrosion and electrolysis are mostly mythical when it comes to closed loop hydronic systems. The corrosion pictured is due to a leak, not dissimilar metals. If it makes you feel better to use a brass elbow or valve, go for it but it's not necessary in a leak free system. Absolutely do NOT use dielectric unions- they cause 100x more issues than they solve.

Re: Best Solution for Connecting Copper to Iron Boiler
if the relief is dripping it is probably an issue with the expansion tank although the relief valve should be replaced every few years anyhow.
if the expansion tank is waterlogged and causing the relief valve to blow off when the system is hot that will bring fresh water in to the system and cause corrosion.

Re: Best Solution for Connecting Copper to Iron Boiler
Not as much of an issue with a boiler, but code here for potable is to use a brass transition fitting between copper and iron pipe. Wouldn't hurt in any event.
Water heaters always need dielectric unions.
Re: Best Solution for Connecting Copper to Iron Boiler
It was either a bad solder joint or some issue with the water quality in the system. If it has glycol in it, that needs to be maintained or it will become corrosive. that is why @pecmsg asked. Occasionally the potable water that was used to fill the system is very aggressive. If there are small leaks and a lot of fresh water being added to the system, that will cause corrosion. In a closed hot water heating system with reasonable quality fluid connecting copper and steel directly isn't an issue.
