Re: Is this boiler plumbing layout ok?
without knowing the loads we can only guess. it may need a buffer tank or the boiler is way oversized(it might be sized for the dhw load). there is usually an anti short cycle setting in the boiler that will make it hold off firing to let the loops cool some, you might need to set that or make it longer.

Re: Copper for condensate pipes? Your opinion
Gordo uses stainless steel now in parts of his Hartford loops and where it interfaces with the boiler, that is good because it's always rotting out there first
Re: Copper for condensate pipes? Your opinion
Both get the job done. Ph and water quality play a big factor. Open up a wet return after 10 years, steel or copper. Steel will usually have a good plaque build up and Atherosclerosis. If there is any in a copper wet return, it doesn't adhere to the pipe walls and can be flushed clean easily. Not so with black pipe.
As a general rule, copper ONLY below the water line and on wet returns. If I do have to make a repair on a steam supply radiator branch that is already piped in copper and its not practical time or $$$ wise for the client, I'm using 50/50 solder or silverbrazing the joints..."softer" and greater flexibility. I've seen joints in buildings I did over 35 years ago....No cracks of the solder joint...95/5 joints are more prone to crack as it is a "harder" joint. Mad Dog
Re: Used Roth Oil Tank Installation
If your tank has a pin hole put a magnet with some gasket material over it.
And if the tank is temp. why do you want to fool with a Roth?
Re: Age of vintage pressure gauge?
the scale is just held on with a couple screws. the manufacturer or the oem can put a custom scale on it. it was very common in the days of analog meters for manufacturers to put custom scales and graphics on meters made by someone like simpson. i would say that could be anywhere from the teens to the 50's. if you find out when gurney existed that could narrow it down.

Re: Age of vintage pressure gauge?
That looks like it just came out of its original box! Really nice. Never heard of Gurney either, but all the old ones were well made. Mad Dog
Re: Age of vintage pressure gauge?
I don't have a clue, but I would guess 1920s. Ashcroft gauges are among the best. I never herd of Gurney though.
Re: My steam boiler water got a little contaminated, so what can we learn?
@Precaud Maybe measure the exhaust gas temperature at different water levels. If the boiler water at a higher level absorbs more of the heat from the burner the exhaust gas temperature may be lower and the metal at the top of the heat exchanger may be cooler.

Re: Navien condensing boiler settings troubles
@Alan (California Radiant) Forbes My outdoor sensor is pretty accurate, differing by maybe 1 degree C from my other outdoor thermometer (unrelated to heating system). My thermostat is wired directly to the boiler at the T/S_1 connector. The circulation pump is connected at the "Boiler Pump" connector, CNP2. It does seem to be running constantly, although I can't say for sure 100%. Thanks
