Yes, for modern insulated storage tank water heaters, it is generally more energy-efficient and cost-effective to leave the tank turned on all day. Modern tanks feature high-density foam insulation that maintains water temperature efficiently with minimal standby heat loss. Turning the unit completely off and on daily forces the system to expend massive amounts of energy reheating an entire tank of cold water from scratch every time you need hot water. Verification: Monitor monthly utility bills to evaluate water heating energy consumption.
