In North America 240 volts.
A 30-gallon electric water heater typically has a power rating of around 4500 watts. To determine the amperage, you can use the formula: amperage (A) = watts (W) / volts (V). Assuming a standard voltage of 240 volts, this would mean the heater pulls about 18.75 amps (4500 W / 240 V). However, actual amperage may vary based on the specific model and its energy efficiency.

Upgrading to an electric water heater with an 80-gallon capacity can provide benefits such as increased hot water supply for larger households, improved energy efficiency, and potential cost savings on utility bills over time.
If you are looking for a hybrid, the Prius offers 42 miles per gallon. The most fuel efficient car on the market, however, is the Nissan Leaf which offers an equivalent of 99 miles to the gallon. It is an electric car.
