Re: Boiler condensation
As I thought… the intake is sucking in exhaust.
Separate the terminals. You could try to shorten the intake but I would still think that the exhaust could drift under the deck. Safest thing is to periscope up the exhaust 12" AND shorten the intake...

The JOT wasn't great when they where new, so it lived a long life. I would go with the MegaSteam.

Re: Peerless ECT-03 vs WM SGO-3 vs Williamson OSB-3
The contractor is more important than the brand name of the boiler. Look at the google reviews and discount the bad ones form folks that don't want to pay for quality work. Look at the ones that say what a good job the contractor did, or the ones that say than they had a problem but the contractor stuck with it.
Stay away from the contractor that can't solve the problem and just stop returning calls.

Re: System 2K boiler oddly fires briefly
@KyleO based on your video, I believe what you have is digital sensor that is intermittently losing its signal to the manager. In the video you have a zone that is calling and heating and the return is coming back at 170 deg so the burner is shut off based on return temp at the time. Then you see the temperature bars go out and the burner light comes on, and that because once the manager loses the temperature reading from the sensor, it will switch to service board mode where it fires the burner to run up on the high limit instead but then the sensor sends a temperature signal and the manager reads the 170 and turns the burner light back off. That is my best guess based on the short video. When you call your service company, I would suggest they bring a new sensor with them and we can verify it with the tech when they are on site.

Re: Air to Water Heat Pumps
You know, all this reminds me a little bit of the bad old days, 60 or so years ago, when I was a pretty wild kind of guy and into drag racing. SuperStock. There were lots and lots of discussions — some rather heated — and theories on how to make a gofast car gofaster and stay at least vaguely street legal. Horsepower ratings. Best rear axle (both the axle itself and suspension). Carburetors. Timing curve mods. Headers. The lot. A lot of guys (and gals) did a lot of tinkering, and there were always the guys with fancy instruments who proved us wrong…
But you know what? At the end of the day it was pretty darn simple: did my car get to the other end of the quarter mile before yours did? End of story.
It was fun while it lasted, until the EPA took our toys away…

Here it's much the same. Is the little old lady warm and comfortable in her house? Can she afford it? End of story.
Re: Peerless ECT-03 vs WM SGO-3 vs Williamson OSB-3
the coil can be replaced without getting a new boiler
Re: Peerless ECT-03 vs WM SGO-3 vs Williamson OSB-3
Whichever… the quality and skill of the installer is at least as important as the label on the boiler.
Re: Peerless ECT-03 vs WM SGO-3 vs Williamson OSB-3
Is the coil leaking? A bad coil is a horrible reason to replace a boiler. Buy an electric water heater and plug the coil.
