Well, I have an all electric house and the water heater stays at 120. Hot water on a cycle without a heater is what I use for washing my casual work clothes and some stuff worn around the house (per your suggestion numerous times to various people here John). Cycles used for towels, sheets, personal whites, meal cloth napkins, kitchen towels, cleaning clothes all use cycles where the heater is engaged and I opt for different degrees of hot water temperature for the type of load it is.
