Re: Intermittent pilot ignition control - replacing cable/wires?
If you take a jumper and ground the combination ignition/sense wire it will do the same thing as unplugging it, it will disrupt the flame rectification signal and the control shouldn't open the main valve at startup and it should shut down the main valve if you ground it with the burner firing.

Re: Steam heat system fitting
I’ve seen this in an old book. Can’t recall which one. It’s a specialty tee that allows the steam to go to two floors. The object was to lessen the amount of returning condensate in either riser from the tee.

Re: Help draining a old steel expansion tank.
So I just read an article about NOT having auto air bleeders on a system using a bladerless tank. I DO have one of those on a high point of the boiler a little before the return. Is this the cause of my issue?Yes. You do NOT want to bleed air out of the system at the radiators. You want the Airtrol funnelling the air back to the tank. Your auto bleeder will eventually bleed all the air out of the system and make the expansion tank get waterlogged, just like you now have.

Re: This a bull head t?
The vents are in the second pic. Two radiator traps are piped between the ends of the steam mains and the dry return. We call these "crossover traps" since they route air from the steam mains into the dry return. The large device in that pic is a "vent trap" which may or may not have a vacuum check screwed into the top- this is where the air actually leaves the system. From what I can see this is probably a Dunham Vapor system.
Re: LG Red HeatPump (ducted) energy consumption
I was just going to say, there is no heat strip, this is strictly condenser (inverter) outside and air handler in the attic. I have a back up gas boiler with forced hot water baseboards as back up... this system (ac and heat) runs independently from my gas boiler.

Re: LG Red HeatPump (ducted) energy consumption
Good question. It's just in the LG thinkq app. At first I thought maybe the app was wrong, so I waited the month and the electric bill confirmed my suspicion, so it seems accurate however it's reading it

Re: Should I install an Outside Air Thermostat for Viessmann Vitodens 100 B1HE-199?
Eric, thanks. It's difficult to define "normal" cycles; the easy answer is: "it depends". Heat Loss of the building changes as it gets colder out. Your system is zoned with DHW so there are a number of possible combinations of demands on the boilers from 1 to several. By lowering the operating temperature, you are more or less proving that an outdoor reset curve will work. Your process is essentially finding the correct boiler temperature for a given outdoor temperature. Going out on a limb here, I think your boiler is probably a bit oversized to the load; an accurate heatloss will tell the tale for sure. If you find that your boiler can heat the house at say 150 when it's 40 outside and you have to go to say 170 when it's 20 outside you have essentially found 2 points on a heating curve that will define an effective curve for your home. Don't get too hung up on how often the boiler is cycling. Just know that longer circulator run times with the lowest temperature water that will keep your house comfortable (comfortable is personal - we are all different) will reduce cycle compared to a high fixed setpoint whenever a themostat calls on the boiler.

Re: Minnesota Right to Repair Law
Here is an interesting story about a Polish made train which was designed to fail if someone other than the manufacturer tried to repair it. I suspect this is the type of thing they are trying to legislate against. https://badcyber.com/dieselgate-but-for-trains-some-heavyweight-hardware-hacking/

Re: Need help with Burnham 405 1979 boiler
Those pipes go to the automatic feeder valve. That valve at the bottom left is a bypass to bypass the water feeder and fill the boiler directly. It should be closed. That is what is happening with that loop. It is essentially 2 separate pipes with that closed valve connecting them. It is kind of a cleaver and neat way to pipe it but is a bit confusing to sort out just looking at it.
