Re: Cold water is hot due to amateur plumbing
Hi, Just to address one point, cross connections can happen simply from hard water changing the way seals seal. I'd do that test so the possibility can be ruled out.

Re: Boiler not firing/extremely delayed when hot water calls for heat.
The end switch wires from the zone valve go in to the zone control terminals 3 and 4? if that is the case the end switch in the zone valve is almost certainly bad.

Re: Steam-one boiler or two, and, Atmospheric vs Gun
Atmospheric is cheaper and less problems but the efficiency with a power burner is a little better.
Re: Overfill alarm
I would like to see the actual ordinance wording to see if my alarm with visual overflow ability will fit the words. If it says electronic sensor, I can certainly add some wires and lights to that with a condensate overflow switch like the one on AC evaporator coil pan. They would be parts W, X and Y
Re: Overfill alarm
Please edit to remove prices. I thin this is exactly a few people here's territory so there should be some people familiar with the rule.

Re: Overfill alarm
More rules that are not needed. Just trying to force people into heat pumps.

The op said"
"used the whistle stop provided by the oil delivery company"
Sounds to me like this town is against oil as a fuel and is trying to force the issue. I think they want some type of wired alarm system.
Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
The burner and boiler are not the problem. The problem is the "technician"
First words out of their mouth is "you need a new boiler"
Re: Boiler not firing/extremely delayed when hot water calls for heat.
swap one of the working and non working zone valve powerheads and see if it follows the powerhead.
i'm pretty sure the end switch terminals from the zone valve land on terminals 3 and 4 of the zone valve controller and the zvc passes that signal to the end switch connection to the boiler.

Re: Axeman-Anderson oil fired boiler vs. Burnham oil fired
The oil burner is the part that is not operating. You may just need a simple part like a ignition electrode assembly, or perhaps the burner fan is so clogged with household lint and pet dander that the air adjustments can no longer be adjusted for proper combustion. 34 years ago, oil burners were pretty much the same ones that are available today. Carlin, Beckett, Wayne, and some others have not changed that much in the last 30+ years. the chassis is still the same, they just add more or better parts to that same burner housing. If you can determine the problem with the burner, you may not need to replace the boiler.
But replacement parts will not cost as much as a new boiler, so maybe someone just wants the big sale. What happens if you get that new Burnham boiler only to find out that the oil line from the tank is plugged. That new boiler will have the same problem as the old one. New and old burners can not operate if the fuel line is plugged. You need to find another service technician. I M H O
