Re: Trying to use an Ultrasonic GPM meter to figure out my system head.
if the numbers Ed posted are reasonable, you need more pump, the 0015 isn’t going to get what you want
The 0026 not a cheap date or equivalent.
Maybe find an older style non electronic pump
a 26-99 Grundfos would cover that load

Re: Line voltage at thermostat
It wouldn't be allowed with line voltage wiring (except with service cable and dryer and range ckts in certain cases), but as long as the signal on the bare wire or casing is grounded or can be grounded there aren't really rules prohibiting it in low energy wiring.

Re: Triangle Tube Ceasing Operations
Closing their doors may stop some of the hemorrhaging, but it won’t relieve them of the liability for what’s already out there in the field.
We had over 25 hours trying to correct one that we installed at the end of last season before they announced the recall. Everyday, tech support kept telling us to do something different when they knew there was a design flaw in the boiler. We finally demanded and got a new boiler. Then, a couple of weeks later they announced the recall. They knew all along that there were issues.
It’s a shame since they were the ones that introduced the fire tube HX in the US and the original boilers were very reliable.

Re: Static Plate confusion (firing down Utica SFH3100).
"Trace of smoke" is one of those hoary traditions that refuses to die. No properly-installed and -tuned flame-retention burner has any business making any smoke whatsoever.
I was taught this way, by @Firedragon , @Alan R. Mercurio and others: When tuning a modern burner we first look for the point at which the burner starts making smoke, then open the air gate just until the smoke disappears and you have a nice clean test paper.
Then we add enough air to reduce the CO2 percentage by one point. For example, if the zero-smoke point is at 13.5% CO2, we'd set it for 12.5%.
This gives a bit of headroom, also called a margin, to allow for changes in fuel or air supply. Both air and oil get more dense as they get cooler, and if the burner is set too close to the edge of clean combustion at the servicing, these seasonal changes can cause it to make smoke or soot.
The proof that this works can be seen the next time we service that unit. There is little to no brushing and vacuuming to be done. The unit has therefore maintained its efficiency throughout the season, the customer is happy, and the oil supplier probably isn't (but I don't work for the oil company).

The well for the new Aquastat is the same one as where the sensors for the 2107 were.
What they did is totally incompetent.

wall furnaces can lose their pilot light and then you are still without heat
How much redundancy is enough?
Neighbors, friends or property managers you can at least stay in contact with.

@arcticman said "Pretty sure the vented heaters and electric heaters cannot operate automatically if the power goes out even for a second. When power is restored they need to be manually activated.
Our power goes out often… while we're away if there's even a brief outage they would become useless as a backup."
The Williamson COZY heaters that are not connected to the house's electrical system will not have any problem with the electrical system that it is NOT CONNECTED TO. Well that is my experience anyway.
This model Floor Furnace will keep a good size home at 50° even at very low outdoor temperatures. It involves cutting a pretty big hole in the floor, but you can cover it with a carpet when you are home as long as you turn off the gas. When you want it as a backup, light the pilot, remove the carpet and set the thermostat to 50°
