Hi Larry.
No electricity since Friday night.
I have a 5.5hp, 2000 watt generator, ran it to the well pump for COLD water, TV, the aquarium air pump, refridgerator, occasional microwave use.
Its enough, but you must make choises.
Tried to heat water in a covered TWO gallon stock pot, using the heat of the generator exhaust for a bath.
With FOUR gallons of hot water in a standard sized tub, already filled with now ambiant temperature water, (after sitting overnight) its still cold!
More on this later.
