Re: Weil McClain Natural Gas Hot Water Boiler
You can try looking for contractors certified in combustion from the National Comfort Institute.

Re: pro press on baseboard
They say not to press the thin baseboard tubing which make "M" tubing look thick. Many have done it without issue. If it was me I would solder it anyhow.
Re: Oil boiler will not engage at all
Ah… that box is a safety to prevent the boiler from firing if there is insufficient water. Your pressure gauge seems to indicate you have pressure — but they have been known to lie.
I would stop trying to fire the boiler by overriding that safety, and find out if there really is enough water in the boiler — and if there is, why the safety thinks there isn't. And then fix the problem. Dry firing a boiler never ends well…
I might add that a chronic leak, cold or hot, is not something to ignore (unless you are an SR=71) and should get fixed before you try to run the system again.
Re: Need to replace corroded supply to radiator
As far as the radiator piping goes your correct the water will take the path of least resistance so if you undersize the pex to much you may not get heat in that radiator and will create a balancing issue.
Since it is 1 1/4 now I would use at least 1". You could also use 1 1/4" copper tubing. I am assuming you don't want to use black pipe you could find a plumbing supply that could cut the pipe for you. Big box store can if they have some one who knows how to use the pipe machine correctly.
Re: Controlling zone valves for a boiler/chiller system?
Um.. may I humbly point out that if you are leasing the space, anything you do must be approved by your landlord, who may have his or her own ideas…
Re: Where to add air vents
Point C would be fine for the vent, but don't think that plug is coming out with some toy wrench. As Ethical alludes, your last radiator will be venting a bit extra pipe, so you may want a larger vent on it if the system can handle it.
Do take note though that water hammering and water issuing from radiators indicates problems that won't be solved by piping a couple of main vents.
Re: Cleaning/Descaling Indirect Water Heater-Or is it too rusty?
From what I remember about that Triangle Tube tank, there are no access openings for cleaning. There is an inner Stainless Steel tank that is filled with potable water and an outer tank that has the boiler water in it. (no heat exchanger coil). The only access to the inner tank is through the ¾” male, hot and cold water openings that are welded to the inner tank and welded through the outer tank. Not much space for a spray wash nozzle at a 90° angle to fit in those openings. The cold inlet has a plastic dip tube that runs to about 4" from the bottom. So no real access through that opening.
Since that tank is over 30 years old, you may want to think about replacing that indirect with something compatible with your new future system.
The center opening is for a vent to purge Boiler Water from the top of the tank. No potable water access there.
Re: New Hydronic System - Much More Complex Than I Am Used To.
a large Taco just as above the boiler for boiler loop?

Re: Oil Fired Hot Water Boiler - What is main difference between WGO-6 Gold and Velocity Crown Boiler?
The quality of the installation is much more important than the brand name of equipment. Focus on who is doing the job rather than what brand they are installing. How was the size of the boiler determined? Did either contractor perform a manual J load calculation? What kind of warranty is offered? Does either estimate include any upgrade to the near boiler piping and hydronic components?
Heating systems can't be compared like buying a car or refrigerator. The assembly of the complete boiler system differs depending on who does it. Your boiler might be the same model as the one in the building next door but reliability and efficiency might be drastically different depending on the quality of the installation.
