Cost difference of propane vs electricity

Please remember electric is the most ineffecient energy source. There is a 60% line/transmission lose. Only 3415 BTU's per KW.
My house is all electric, due to being in the country. If I used propane my bills would be 10-25% less.
But if I converted to gas it would take 10 years just to get my investment back. We're going full time soon.
Rv'ing: I use propane to heat if I'm paying the utilities. If they are included in site rates I use electric.

First, you do not pay for the kwh you do not receive. Those losses are to the utility or transport company. For energy you receive, resistance electric heat is almost always 100% efficient. Not always cheap but efficient as all the energy goes into the area being heated. With heat pumps, they can be more than 100% and almost never any less than that.

For electric vs propane, the lowest cost option will always be a heat pump. Electric resistance heat vs propane is usually a wash with the advantage to electric for ease of refill or to propane for portability which ever is more important to you.

For home heating, natural gas as all those options beat hands down if you can get it. Was a time that rising gas costs were making heat pumps and gas heat similar but significant increases in availability of natural gas in the last few years shows that that will never be the case again in our lifetimes.
