Off Grid Mini Ammo Box Water Heater / Heat Exchanger

An interesting project for heating a small enclosed space.



Note there must be provision made for a safety valve / expansion escape mechanism. The same basic mechanism could be adapted to a large stainless steel water reservoir. A water depth gauge would also be handy.

This is a clip that demonstrates the snowmobile tiny cabin camper: It could be adapted to an ice hole fishing shack.

 

Very cool!
