A propane generator will not buy you much time or output.
If the home owner has natural gas? They should could get a natural gas generator, that way they have a continuous supply of fuel if the grid fails.
Grid and gas failure? That happens only after a significant event, like a major earthquake. Not much you can do about those sorts of events. ( The person lives in Ohio… so not as much concern. )
Cost-wise? They would be better with a dual fuel system for heating. They live in Ohio, they probably have AC so moving to dual fuel when the AC system needs to be replaced is the smarter option.
A friend of mine just got a generac generator, fully installed it was 17k. Pretty steep, not to mention the gas bill with any significant outage will be huge.
