Do-it-yourself stainless steel boiler 240 l 

Hello. The video shows the process of making a boiler from stainless steel.
Ten used a dry one. The water pressure in my system is atmospheric, that is, minimal, so this form of the boiler is allowed. It also has a heating coil installed in it, I plan to connect a solar collector. I welded stainless steel with a stainless wire, carbon dioxide gas is much faster than boiling it. I plan to make a solar collector as well.
Thank you for viewing
