An electric water heater can supply enough hot water for a large family, but the key is choosing the right size and type of unit. For larger households, a bigger tank or a tankless electric water heater may be necessary to meet the demand. However, electric models generally have slower recovery times, meaning they take longer to heat water after the initial supply is used. This can be a limitation if multiple showers, dishwashers, and laundry machines are running simultaneously. In such cases, some families might find gas water heaters more suitable due to their quicker recovery rates.
