I convert an old propane tank to burn underwater as an immersion heater for a lot of hot water.
100% offgrid!
Unlimited hot water without propane or electricity.
I use a homemade underwater woodstove to make a lot of hot water in a realitively short time.
I also make use of the waste heat to cook breakfast.
75-80 gallons of hot water in 1 hour with free wood.
