Re: Residential boiler cycling again. House cold.
is there a tank in the attic? cast iron converted gravity systems can be hard on wet rotor circulators if there is a lot of rust in them. it is possible that it was just air bound when you replaced the circulator before. it will heat better by gravity if you open the flo check.
if the boiler piping isn't right the air will migrate out of the compression tank and in to the system.

Re: Question about B-vent termination and CO
First of all, that B-vent does not meet code requirements. it is obvious that there was no municipal permit issued for this install, or the local inspector is clueless.
Secong big No No is that B vent should not be exposed to the outdoor temperature for the entire vertical distance. And there are several other things that are wrong. I will make a diagram of what might be a better design.

Re: Expansion Tank Orientation
Pockets of air in the water side of a tank are inevitable. Regardless of its angle of install. A reason why the orientation of the tank is not critical as mentioned numerous times here, is because a properly sized tank with a air separator (preferably a Micro Bubble air separator ) will remove said air/micro bubbles as it is absorbed by the water.
@ccstelmo Clever use of the steel tanks.
The reason folks install there tanks as shown above is an example of good workmanship. Horizontal or vertical.
@Alan (California Radiant) Forbes Some beautiful pictures. Always like to see your work. Thanks for sharing.

Re: Residential boiler cycling again. House cold.
What is the water pressure at the boiler? Do you have the old-style steel expansion tank, or a modern bladder tank? Have you bled the radiators?
With a relatively new pump, it sounds more like you have air in the system that's preventing circulation. Post some pics of the boiler gauge close-up, and of the entire system showing the expansion tank and any air eliminators.

Re: Water boiler with tankless coil not enough for DHW
I feel like I’m wasting oil by keeping the boiler so hot (150) for the chance I “might” need hot water. Also in the summer when the boiler is only used for DHW this can get expensive.
I feel like you are too. Get a standalone water heater. An indirect tank would be better than what you have but will cost a fortune in parts and labor and you’d still have to run the boiler all summer
Re: Natural gas price spikes in MA
@Jamie Hall If we don't know the breakdown, let's be cautious about complaining about policy regarding pipelines. I've always been under the assumption that delivery was delivery from utility to customer. Supply would include all the costs of gas to utility, whether via pipe or ship. But maybe I'm wrong.
I think regardless, there is an issue on the horizon. Maintaining the intra utility gird is expensive - this largely fixed cost can be divided out by therms and/or bills but as consumption growth flatlines or decreases, this will lead to price increases. We might be approaching the point (arguably we're here now in some markets) were we need to consider abandoning the gas grid to some extent. Trucks with propane/oil and/or electricity alone might become the go to here. My utility gas side is pricey and getting worse, at $190/year fixed, $1.11/therm delivery and supply changing constantly (currently $.60). Oil starts to look good at those delivery and fixed rates!
