Below is written by a state boiler inspector in MI. I used to work with Jim and know his craftsmanship in metal working.
> 1. Privately Made - Carson City Machine, Carson City, MI -
> Jim sells locally and has designed a round firebox inside of
a round water jacket boiler. His effieciency for an outdoor boiler
appears to be the best we've found for the buck. He has built just
over 110 boilers the past three years with zero returns. He is a
retired machine and tool engineer with years of farming experience.
>
> His stoves look internally similar to a Wood Master boiler, but
with a larger firebox and firebox opening. His water jacket holds 130
gallons of water which heats his 2500 sq. ft. home and 1500 sq. ft.
shop. Jim does not advertise and is currently back ordered.
>
> He charges $4,000 for his unit... and only makes this one size.
He estimates over 300,000 BTU but has no offical calibration. We were
really impressed by his stove, his knowledge, his workmanship, and his
experience.
