In "The Lost Art of Steam Heating Revisited" on Page 81. There is a suggestion:
"If you have to submerge a tankless coil in the summertime, do it by hand."
I'm confused. How do I submerge a tankless coil by hand. In my "fixed mindset" I picture only one location for a tankless coil. I might have this mixed with an indirect.
Thanks for any help.
