Re: Steam coming from valve at side of Grant Euroflame 50/70 conventional oil boiler
it appears to be a air vent.
that boiler is in bad shape!

Re: New Century House with Two Pipe Steam - Questions
You could try opening up one trap and taking the element out and run part of a cycle with the trap open and see what happens. If the issue is whatever is venting the returns is not working then the returns should vent through that trap and they should all heat or at least more should heat. If the valve is set up right and the vaporstat is working right it shouldn't let in enough steam to get to the trap, air should vent out the trap but not steam. If steam starts coming from the return that tells you that you either have traps that are leaking by somewhere or that the boiler return trap is trying to equalize the return but it can't build pressure because it is open.

Re: Viessmann B1KE f380 faults
I've see high winds effect combustion. The cure was to cut the exhaust pipe at a 45° angle.
Re: Interrupted vs intermittent Primary control
ISTR this was done to bring the oil terminology in line with that used for gas. So, "constant" would be a pilot light that stays on all the time, "intermittent" would be a pilot (gas) or ignitor (gas or oil) that comes on at the start of a firing cycle and shuts off at the end, as on a spark-to-pilot or hot-surface gas ignition system or an oil system where the spark stays on the whole time the burner runs, and "interrupted" is where the ignition only stays on when lighting the fire.
Re: Interrupted vs intermittent Primary control
It certainly does.
I could never use the word "intermittent" for a control that held the transformer on for the entire cycle. That's flat out wrong. Everyone should abandon it.

Re: New Century House with Two Pipe Steam - Questions
It should be black iron but copper vs black iron won't be the reason it doesn't heat. It could cause some more minor problems but it likely will work ok.

Re: New Century House with Two Pipe Steam - Questions
Such a beautiful system. As long as it wasn't leaking I'd tune it by addressing the traps, venting etc..but then again, NG is darn cheap and our winters are short and mild.
Re: New Century House with Two Pipe Steam - Questions
I keep forgetting to look at my copy of TLOSH and see if that return trap is in it but I'm guessing the venting of the returns happens through it. If that is the case and it isn't functioning right then the system isn't going to heat well, likely because no one has opened it up and cleaned it since the eisenhower administration.
I think someone mentioned adding a low pressure gauge. You can tee that in here with the code required gauge although that might not be my top priority, I don't think that pressure is your issue:

Re: Air to Water Heat Pumps
Sounds good. Ideally you'd have one zone running at 100% cycle length, that seems like the optimal water temperature.
