How do I choose the right electric water heater for my home?

When choosing an electric water heater, consider the capacity you need based on your household size and usage patterns. Think about how much hot water you use daily, including showers and appliances, to find a model that fits your needs. Standard water heater sizes are 40 and 50 gallons, for tank water heaters. Most homeowners choose to upgrade from a 40 to a 50 if they find themselves often running out of hot water.
