Now you have caught me shooting my mouth off. I know this is true for commercial customers. I thought it was also true in some way for residential customers and it is the only way I can see to explain the power bill going up as a result of turning off the water heater.
My HECO power bill (Oahu) does not explicitly refer to demand. There is however a non-fuel energy charge, whatever that is. I suspect it is related to demand. I know residential demand is a serious issue because HECO will outfit your water heater with a device that lets them drop you for short periods to get them through demand peaks. 9 times out of 10 you would never know they did so because of the storage capacity in the water heater.
