That would depend what schedule of piping your asking about thin wall? schedule 40? schedule 80? schedule 120? giving a hint would certainly help a lot
Typical heating boiler setpoint is around 180*, if you are looking to economize, look into having a reset control installed. The reset control will adjust the boiler setpoint based on outdoor air temperature. On a 70* day you would have 70* boiler water temp with a reset schedule of 1.5, for every degree outdoor temp drops below 70 the boiler temp would rise 1.5* so on a 0* day, boiler temp would be 175*. The reset schedules are adjustable.
You would add it to the boiler
The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.
Labor alone for a residential boiler would be around $800 while a water heater would be around $210-$300. These are typical rates for Connecticut anyway.

A boiler can be a closed system if you include the pipes it is connected to, but usually there are relief valves that will allow the escape of steam to protect against excess pressure and inlets that will allow adding liquid to the boiler to make up for fluid lost from the pressure valves. Also most boilers are imperfectly sealed so they leak a little bit. If you do not consider the attached piping, then a boiler would not be considered a closed system since it would be constantly sending out steam and receiving condensate in return.
What schedule piping as schedule 40 fittings are rated for 125# thus your 140 PSI would be really dangerous to try on standard fittings

That would depend on the boiler - look on the boiler plate it will tell you the answer for that boiler there.
At the present time Ct does not have a statewide Boiler operator license. Some citys in Ct do require a license . A statewide license is being contemplated for the near future. The nearest chapter of the "National Association of Power Engineers" NAPE would be able to where you could apply for a boiler operators license or training. Give them a call. Bear
Piping material used for forming gas would be 316L stainless steel.
We would typically call this a rifle.
I would open it.
One may decide to purchase a used boiler because of the lower price for a used boiler compared to new boiler, in that case one will have to compromise with the quality of the boiler.
I would recommend using a double boiler. If a double boiler is unavailable, I would heat it on low heat and stir it frequently.
I would look up your boiler specs or maybe contact that boiler brand and they would be able to help you because your question can be for many different situations.
