The label on a 240-volt electric water heater typically indicates the element wattage, which is often 4,500 watts. This specification is crucial as it directly affects the performance and efficiency of the water heater. The wattage determines how quickly the unit can heat water; higher wattage means faster heating. Most residential electric water heaters designed for 240 volts commonly use 4,500-watt heating elements, making this detail essential for proper installation and operation. This ensures that homeowners can expect adequate hot water supply and performance, matching the requirements of typical household usage.

In contrast, tank size, voltage compatibility, and installation height, while pertinent factors in determining the right water heater for a specific application, do not commonly present as standard indicators directly noted on the water heater's label like the wattage does.
