sometimes tightening a little first then gently tapping the wrench with a hammer while loosening helps.

Re: Sanity check plan new zone
sounds like you need to shop for a better brand of zone valves.😉
There is not a lot of difference between a zone valve and a zone actuator on a manifold. Often they are the exact same operator as one another
Zone valves with a short life span are often short cycling themselves to death
On the average a ZV cycles 5000 times a heating season. Quality valves, gear trains, motors and switches are designed for 100,000 cycles. Or 20 years of service.

Re: Ecobee premium wiring from old honeywell
Shame to replace that "outdated" thermostat. It's more reliable — and precise — than anything you can buy today. A lot simpler, too.
I like the Carlin unit that @EdTheHeaterMan suggested, but there's nothing wrong with the other one.
Frankly if it were mine I'd replace the whole burner control with a Carlin 70200 control — a lot more functionality. But that's me. It I were going to do it at all — which I wouldn't, since I wouldn't replace that old thermostat unless I were paid — well — to.
Re: AC compressor near heating oil tank?
Check your local codes. My condenser is 3 ft from my Roth oil tank, which is 3 ft from my LP tank. All along the property line.

Re: Steam boiler install
If there are no returns at the ends of the mains that means it is a counterflow system, the condensate returns to the boiler in the opposite direction as the steam. There need to be drips at the boiler to allow the condensate to return to the boiler. they need to connect separately to the return below the water line. the header should be piped as shown in the boiler installation manual and each main should connect separately to the header between the boiler connection and the equalizer.
That ~60 year old boiler is not piped correctly but it might have worked ok because older boilers had more space inside for the steam and water to separate.
You always size steam boilers based on the size of the radiation connected to it. You need to measure your radiators or other emitters and find the equivalent area from the type and size.
There will need to be some asbestos abatement to replace the boiler.

Re: 1 thermostat five zone valves
@Alan (California Radiant) Forbes has a great idea, and no relay is needed. Use the end switched from zone 3 to power up zone 5. Add W jumper for Zone 1, 2, & 3 and another W jumper to 4 & 5 as shown below.
CAUTION: If you are using a three wire zone valve you may cross phases on the two transformer because zone valve terminal 2 is the same as C on the transformer, so connecting the end switch may cross the C of one transformer to the R or the other transformer inadvertently. So use the relay idea if you are using 3 wire zone valves.
Re: Sizing a New Steam Boiler
The 33% is built into that spec already and 33% is too much anyway.
The 288 is what you want.
