Thread: Saving on electric bill: 110 or 220?

    Default Saving on electric bill: 110 or 220?

    To save on the electric bill, is it better to use 110 or 220 volt electric appliances?

    Will it save more power baking potatoes for 1 hour in the 110 toaster-oven or the 220 wall oven (same temp)?

    Will it save more to cook for 30 minutes on a supplementary 110 burner or an electric frypan - or simply to cook on a built-in 220 cooktop burner?

    What if one is slow-cooking a stew or spaghetti sauce all day....use 110 or 220??

    Is there anything to the suggestion that one should not use more than ONE optional 220 appliance at a time --and that before using the 220 oven, one should turn the A/C up high, so it won't cycle?

    It makes no difference, watts are watts regardless of the working voltage. A heating appliance will just cycle off more often if you're using a higher powered one (big oven -vs- toaster oven). However, a large oven may use slightly more power than a smaller one because you have more mass to heat up in the large oven. But a large oven may be better insulated than a toaster oven, so you don't really know which is better.

    The only reason to not use more than one appliance at a time would be because your electrical service is too small and you blow fuses. Cost is the same -- you can use 2 KW for one hour, or 1 KW for 2 hours -- the total is 2 KW-Hr in each case.

    Turning up the AC won't help save when using an oven simultaneously unless you don't plan to turn the AC back down again. Your oven is dumping more heat into the house that will either dissipate (when it gets cooler at night), make you hotter than you want to be, or the AC can get rid of it (but that costs money). If you're trying to cool the house, I consider cooking outside on a BBQ or perhaps just cooking on the hot asphalt.

    I wouldn't worry about any of the things you've mentioned, as the cost impacts would be minimal on your bill (except perhaps using the oven at 450 degrees all day long with the air conditioning on).

    Use the microwave. That will save the money. Otherwise watts is watts as stated. The only advantage is smaller wire required for 220 as the amps are lower.

    Or you can turn off all the lights in your house and go to Wendy's for your baked potatos. This will save a bunch on your electric bill.

    We have an electric oven with the convection feature. Use of the convection fan is optional when baking but when we do use it, the baking time is shortened a solid 1/3rd. Even during oven warm-up, with the convection feature turned on, the oven comes to temp much faster. The downside of convection is you need to frequently check (through the glass, no opening door) what's going on in the oven because over cooking is a real possibility. The upside is, it is definitly a money saver and shortens meal preparation time.
