I have a traditional 220 volt electric hot water heater and wouldlike to estimate or measure how much electricity it is using.Suggestions?Has anyone here done this? What results did you find?Are there any national statistics on this?Thanks.

How much it draws is written on the label.Or you could time the electric meter going around.Hook a 220V clock across the heating element.The clock runs only when the heater is on.Have an electrician do it. House wiring isunsafe....my lawyer made me say that...'cause it's true.Depending on the age of the water heater,there's an "energy guide" sticker on it that shows the rangeof usage for that type of appliance. If not,go visit a water heater store and read some labelsthere.All electric water heaters use the same amount of energyto heat the same amount of water. Differences are inhow much energy is lost thru less-than-perfect insulation.I just went thru that procedure using a currentclamp and a computer. I can tell you exactlyhow much my water heater is costing me.A shower costs me 16.5 cents.But...I only have one option.USE LESS HOT WATER.And I don't need ANY measurements to tell me that.

Astounding. Has anyone lampooned the OP for wanting to heat hot water? I don't remember seeing it yet, in this thread.

Or he was just ignoring the pedants who think they are so clever. I don't stop heating my water when it gets hot. I heat it another 10 degrees or so. A friend heats his 30-40 degrees past hot.
