Electricity Usage & Cost of a Water Heater

A water heater is a crucial household appliance that provides hot water for showers, baths, dishwashing, and laundry. On average, a water heater uses around 4000 watts to heat the water to the desired temperature. The actual energy usage can vary depending on the heater's size, type (tankless vs. tank), and the temperature setting. Tankless water heaters tend to be more energy-efficient as they heat water on demand, while traditional tank heaters maintain a reservoir of hot water.
