We also have a 1100sq. ft. home. LP powers the range, water heater, and forced air furnace. In the past we powered the lights, TV and well pump with a open frame 3500W generator.
Two months ago we installed a 8kw Generac Guardian standby generator with a auto transfer switch to power a sub panel that includes all of the circuits we wanted to run for including washer and dryer. We often have power outages, some up to 5 days. It has worked twice since installed and performed as expected.
We chose LP because we already have it available with a 1000G buried tank.
NG would be a good choice, however, if you wish to be self reliant, LP would be my choice because the supply is at your residence and would not be dependant on an interuptable source of fuel
