Re: Clothes dryer: propane vs. electric
I've been looking at appliances a lot lately, trying to decide if it is worth replacing any of our old, probably less efficient, but perfectly functional appliances with the newer energy star models.
According to the energy star people, they don't rate dryers because there isn't a significant energy savings potential there - a dryer heats air, and blows it through the tumbling clothes, so you essentially have a heater and a drive motor, neither of which has much potential for energy savings.
I've seen lots of suggestions that I should consider replacing my washer and / or refrigerator, NOBODY has suggested replacing the dryer - I had one of those "free energy audits" done by the utility co, and the guy explicitly said not to change the dryer.
Those same sites all said that gas driers were overall more efficient than electrics - the total production costs for the electricity to run the heating element in an electric meant much lower efficiency for that unit than the relatively efficient gas dryer burner.
I will admit I was looking mostly at Natural Gas units as opposed to propane, because that is what I have - cost aside, propane in general is less efficient than NG due to the basic chemistry involved, but still it's better than electric for this application.
