Remember this every single load of hot water costs you three times as much MONEY (never mind time) using generator gasoline versus LPG.
Down here an all electric house would cost $800 monthly. And that's on public power.
Short term electrical use screams for batteries and inverter. I shudder to think the cost of what polluted crankcase oil, carbonized valves and combustion chambers and starter motors would add up to. You're going to end up paying through the snot box for ON/OFF/ON/OFF/ON/OFF generator use.
