A note to y'all who might be looking for a generator...
Get brand comparison anyhow you choose.. but the ting to be sure you get is a generator big enough for 220v - That it HAS a 220v receptacle for output. That will start somewhere around 8500w models.
The reason is this: If you have 220 output, you can install a manual fail-over box to your breaker box on the house pretty cheap. This has a lever to throw that kicks OFF your Mains IN - your power from the pole, and switches that 'power IN' to a 220v weatherized receptacle on the outside of your house.
With a prepared cord, all you need do is throw that lever, plug the cord into that receptacle, and the other end to your jenny, and away you go - your house is powered.
But understand: even though you have 220v it is unlikely you get to use 220v appliances. More than likely it will not run your electric dryer or electric stove - And even the nuke will be questionable.
But your lights, fridge, freezer, gas furnace and so on - very likely the rest of the whole house will work like normal.
If you have an electric furnace or baseboard electric heat, none of that will work off a low end 220v generator. So in this case (and any case really) a secondary heat source that does not require electricity goes hand in hand with buying a jenny.
I would put a wood stove or coal stove WAY ahead of a jenny in priority.
