As hot water over 125 degrees F
represents a scalding hazard.

That is why thermostats were invented.



54 Gal of water weighs 448 pounds.

heating 448 pounds water at 70 to 120F requires 50 x 448 or 22,410
BTU's.


22,410 / 3412 BTU/KWH = 6.5 hours.


The generator gas tank will be empty before a 54 gallon WH would begin
to boil, if there was no thermostat involved.
