On average, it takes an electric heater twice as long to heat up than natural gas. It would take around 60-80 minutes for a new 40-gallon tank to gain 60 degrees, and even longer for a larger capacity tank to adequately replenish.
To maintain a preset water temperature, the water heater must cycle on periodically, even when there is no demand for hot water. Tank water heaters generally have about 70% usable capacity, meaning a typical 50-gallon tank has about 30-35 gallons of truly hot water in reserve for usage. If there is high demand over a short period-a family taking back-to-back showers in the morning or a vacation home packed with guests-the hot water can run out.
