Re: I don't understand the merit of a Delta T circulator in my system
This has been discussed here before, often with lots of confusion. You are confusing the importance of the RWT of the secondary or system loop with that of the primary or boiler loop. You really want lower RWT on the primary loop, that is what determines if you are condensing or not. Running large (or small) DT on the secondary/system has little to no impact on the RWT of the primary/boiler loop. You would be well served to lower the primary/boiler flow as much as possible which would give you the lowest RWT on the primary. Now, how low a flow can you go? You want the primary flow to be the greater of 1. minimum boiler flow (see your install manual) and 2.the lowest system flow you can tolerate (if you can tolerate a 30 degree DT on design day, that is your lowest system flow). Matching the system and boiler flow is what you are after; with a single zone like you have things are quite a bit easier.

Re: Gas Grille outside, gas connector???
@ChrisJ as far as stoves connected in the back you screw a nipple and a 90 onto the stove and drill a hole in the floor. Push the stove into position so that the 90 lines up with the hole in the floor. Then screw a nipple up through the floor into the 90. Gas cock and union in the basement.
You only have to run up and down the stairs 10 time to get this made up.
MA does allow flex connectors now and did before but there was a period of time in between maybe 25-30 years ago where everything was hard piped.
They also outlawed CSST for a while but let it back in
Unless you never worked in MA you wouldn't believe the problems.
the latest thing is high pressure gas. If an existing system is HP with screwed pipe that was always legal but now is not watch out trying to change any equipment or any alterations. Up to the gas co discretion they can make you rip it all out.
Also (and this one really twists me up) you can do a job that meets code and the inspector approves it. If the gas company doesn't like it...they have the last word, not the inspectors, not the state board

Re: What is it ?
It looks like a paper gasket that someone was trying to use to seal up the matched faces of a union, and it obviously didn't work well...

Re: Best and acceptable media's for radiant heat for OUTDOOR applications.
Styrofoam under tubing......I've heard ants and termites like to burrow in it. Maybe lay down some insecticide first, but being in VT I assume your on well water so that may be a problem.
Overall I wonder about just sleaving the driveway tubing, so if it leaks in future you can just dig up the edges and pull in new tubing. Will have a cost of lower conductivity from water to soil though, air gap.
I bigger question is why look for a place to dump the excess heat, just figure out a way to throttle down the boiler. Dumping excess heat will just cost you fuel and labor feeding the boiler.

Re: Best and acceptable media's for radiant heat for OUTDOOR applications.
I doubt you will have much over 150,000 BTU/hr output from that boiler. They typically run around 40-45% efficiencies. That is full fired with dry hardwood
Keep you output expectations reasonable and about a dozen cords of wood on hand

Re: Low water cut off malfuntions
@Jamie Hall said"This is not optional maintenance."
Unfortunately steam systems (all heating systems really) require maintenance to work safely and to have any reliability and longevity. Failure to do this results in major problems. Just like a car. Cars won't run long without oil, boilers need water. Low water cutoffs need at the least yearly maintenance

Re: Burner keeps locking out..tried several things .. what to try next?
Here we go again. How many of these oil line issues have we had lately??
Another suction leak! The technicians you have obviously can't find the leak. You have a suction leak, find it and fix it and your problems are over.
Overhead line if it was me I would change it to two pipe or you can try a Tiger loop
Where are the technicians who can flare tubing and get a line tight?
I admit on threaded fittings leaks are more common since Teflon tape has been prohibited
