Propane vs Electric use on refrigerator

Of course, it depends on the price of LPG and Electric, but when LP is say $1.50 and electric is say 12 cents, LP may??? be (Id have to do the math, but Im too lazy lol) the cheaper heat source. However, electric resistance heat doesn't waste it out a chimney/vent like a conventional forced air gas furnace does. Id opt for the easiest and most convenient unless the price difference was drastic.

 

Keep warm now

I once figured this out, but forget the math now. Bottom line, 22 cents per KWH is the break-point for cost-assuming 100% efficiency for both fuels. Electricity is virtually 100% efficient but LP is lower. Counting effeciency of both fuels the break-point is somewhere around 18 cents.

That's from a an old man with low memory cells. I'll have to do the math again, this time keeping it on my computer.

Based upon what price for propane? That has varied quite widely over recent years. But even so the savings for one over the other is pretty small as compared to the convenience factor.

I agree Kirk, I just figured it out of curiosity from old posts I had read here many years ago. I think it was figured on cost of each fuel supply. Seems like multiplying elect cost X 22, then comparing the result to LP cost told you which was cheaper to use. Those old posts and my math were lost at the website host changeover, don't even remember when that happened now.

If I had that old webpage's exact address, perhaps I could find it with the waybackmachine.

Once on the internet it is always there _ somewhere.

SILLY ME, I just read your OP and my response and realized, SORRY I was thinking about the furnace instead of the Fridge grrrrrrrrrrrrrr

 

On the fridge Id definitely use AC anytime I'm hooked up (mines set to choose that automatically). Less carbon and sooting then that LP flame and electrical usage is very small.

If you are talking furnace vs electrical heaters, we use both. Our furnace heats the bays, so when very cold it comes on during the night to make sure bays stay warm. During day, evening we use space heaters. That way we can go the complete winter without moving the coach to refill propane. Our tank is 32 gallons so will last a typical winter in Mesa with lots to spare. Water heater & frig on electric all the time. Fridge does use propane when traveling.
