Reply to comment by limpymcforskin in Does oil filled heater takes much longer than the fan heater? by Substantial-Elk-1259

I’m not sure what you think needs to be explained at this point but regardless I’m certainly not going back to a fan heater that costed me more and didn’t perform as well.

Once again they cost literally the same to run. That is my entire point lol. Electric resistive heat is 100% efficient. If it's the same room in the same conditions there will be no difference in the cost to heat said room to the same temp for the same amount of time.

You are mistaking the oil heater being more efficient when in reality it just has a larger thermal mass which will let heat off after you turn it off. It still took the same amount of heat to heat that thermal mass up.

Oil heaters are nicer for bedrooms since they are quiet. I'm simply trying to correct that last sentence you said where they are cheaper to run. They aren't.

My dude, my point is in your first sentence. If I can run the heater less often, I am saving money. You can check out my break down again if you want. Pretty sure my electric company wouldn’t lower my bills if I was just mistaking it being cheaper to run though.

Once again you aren't factoring in the extra energy to heat the extra thermal load of the oil.

Also correlation does not equal causation. There are a multitude of other variables that will effect your electric bill.

Yea man, I literally did. You know people don’t live in a vacuum under these so called perfect conditions right? There’s a multitude of factors why the oil heater is cheaper to run for me but you’re free to choose whatever works best for you personally.

EDIT: Less kilowatt hours used = lower electric bill. Nobody is arguing thermodynamics lol.

Thermodynamics can be non-intuitive some times, but the rules are quite simple and don't depend on any "perfect conditions". Anyone who paid attention in a college physics class is rolling their eyes at your willful ignorance. If you're using electricity to heat your home the only things you can do to improve efficiency is improve insulation, selectively heat the rooms you are in, or switch from resistive heating to a heat pump. The fact that your electricity bill went down around the time you made a change to your setup doesn't undo basic scientific facts.
