Re: new boiler needed - 4 options - what to choose?
You haven't done step 1. You need to do a heat loss calculation on the house to determine your boiler size. Without that you are just guessing how big a boiler you need. Just a wild donkey guess based on your house size... all four of those are considerably bigger (too many BRUh) than what is required. In fact, even the smallest one you quote may turn out to be twice as big as needed, even assuming relatively poor insulation and druaght sealing.
So do step 1 first.
As to classes of boilers -- your number 4 will be less expensive to purchase and install, and much less expensive to maintain. Will the difference in efficiency make up for the increased invested capital and the additional maintenance? We go round and round on that one -- which suggests rather strongly that it's a tossup over the likely 10 to 15 year life of the high efficiency units.
As to which brand? You aren't buying a TV set. You are buying a heating system, and other than correct sizing correct installation by a knowledgeable person who will also be doing the maintenance is absolutely essential. Even the best boiler can be converted into a basket case by poor installation, never mind poor maintenance.

Sounds like the capacitor has gone bad.

Re: Gas Hot Water Heater Questions
Hi, Just commenting on the flex line question. In earthquake country, which is in over thirty states, it would be bad form not to use flex connectors for gas and water. Even when tanks are strapped in, they move in a quake. San Francisco burned so badly in the 1906 quake because of gas-line breaks.

Re: Long Over Due
One wonders if the inoculations received from playing in unsanitary 'dirt' weren't perhaps important after all…

Re: Problem with short-cycling, low water, and leaks
Knowing what I know today, I would take every effort to get that boiler tuned into your system. I recently changed my system so it is firing at a similar rate to the radiation as yours about -3% pick up factor, and the system is the best it's ever been.
I completely disagree with those saying change it, waste of money and time from where I'm sitting. The issues you are having have nothing to do with sizing, nothing at all. Losing water is a leak. To give perspective 99 gallons should be 10-15 years of water usage, and you say you have underground returns? That is the place to start with water usage. If they need replaced, I would not put them underground again unless there are zero other options, for me it's always been a dumb idea.
For reference to lose that much water through venting only, a Gorton #2 main vent would have to be venting steam continuously for ~340 hours to release 99 gallons of water. You wouldn't have to look around to find that, the walls dripping would tell the story. Also, since you say the steam isn't reaching the radiator vents, they can't be losing steam by definition.
After you make sure it's not surging and you aren't losing water, then you can tackle venting and balance. Start with main venting, then move to radiator venting, if necessary.
I agree with above about looking at upgrading that header and possibly separating the mains, it looks like they are tee'd together and while it's controversial around here, I believe it's better to have them fed off the header individually for balance reasons.

Re: Need a new boiler or should I go tankless
Prices are not allowed on this forum. My vote is for new boiler. With an indirect for hot water. Looks like you have a tankless coil currently for domestic hot water. Probably the worst way to generate domestic hot water.
Re: Boiler Vent Pipe: 30 ga Temporary Or Don't Try It
30 gauge will last more then a week. You can order 26 gauge for the repair from an online supplier like Amazon or SupplyHouse.com
