Re: My SteamPunk boiler
Yeah, I would start saving………….and I would save fast! I don't know if you're going to install the new one yourself or not but if it was me, I would size the new boiler and have it in the basement on standby.
But I commend your ingenuity you did a neat job. Just doubt it will last.
Re: My SteamPunk boiler
The boiler itself isn't all that expensive, for that amount of work you could have replaced it.

Re: WM CGa control board
High failure items on control boards are, solder joints, relays and capacitors. If you (or a friend) can deal with those items it can be an inexpensive repair.
For most industrial electronic repair companies the hourly rate makes it not economical to repair circuit boards that can be (rather) inexpensively replaced.
There are places that seem more focused (and probably others out there)

That appear to do that type of work, I have never dealt with them.
IMO (I'm not a Lawyer, but have done a tiny bit of research) where the liability issue mostly comes in is when someone modifies the circuit board away from the manufactures original intent. Simply correctly repairing age related or use related defects, is not a big deal.
The pipe is leaking, the plumber replaced it.
The capacitor is defective the electronics tech replaced it.
Not the big drama some folks seem to want it to be.

Re: Domestic hot water
I might check the check. as @Kaos mentioned. when you started to heat for the first time this season the check valve may have not completely closed on the space heat side of the system. An easy to check it is if the proper valves were installed you can shut off a valve to the space heat loop to the AHU and see if the problem goes away.
The following diagram illustrates how the water can flow backwards when the circulator pump is off and the check valve is passing.
When the circulator pump is operating, the reverse flow can't happen so you get HOT water. When the circulator is not operating the reverse flow will allow lower temperature from the AHU coil to mix with the Hot water and you end up with Warm Water
Re: Gorton #2 or Hoffman 75
Hoffman products are very high quality, as are Gorton. The greater air expulsion rate of the Gorton #2, which is in the same price range and close in height, make it the better choice in most cases. Mad Dog
Re: Cost to clean a heat exchanger?
They don't make a more simple boiler. That's an open draft hood, so I hope the tech got the probe up over the top of the block. With those numbers, it seems the techs sampling was diluted. Atmospheric oxygen at sea level is about 21%, so getting 16.58% during a combustion test means the tech didn't stick the probe where it needs to be stuck.
@Evan0307 , did you see for yourself the dirty flue passages in the boiler? Dollars to donuts its clean as a whistle.

Re: Cost to clean a heat exchanger?
Combustion is way off. I don't see a HX getting dirty with those #s but anything is possible.
CO needs to be below 100 below 50 is better and it should be a lot lower than that like 10
Co2 should be more like 9
O2 maybe 5-6
So your way off I am surprised it ran
But check the service manual for what the combustion #s should be mine are just a reasonable guess.
Something is way off and I suspect they never combustion tested it at start up.
Re: Cleaning HVAC Ductwork?
Your right but it wasn't always that way. With modern burners and boilers, I don't consider oil boilers dirty but they have to be set up properly.
I agree that a lot of boilers can go maybe 4-5 years without being cleaned. But they are still thing that need to be done during a proper tune up. Nozzle, filter, electrodes check combustion and oil pressure and test safety controls as a minimum. In fact the nozzle can go many years with clean oil.
