Electric Storage
Electric storage water heaters have large tanks, usually at least 100 gallons, that are insulated to hold heat. They allow you to heat water overnight, when electricity is in low demand and less expensive. Electric utilities, especially rural cooperatives, often offer discounts on the water heaters themselves and a low rate for overnight electricity.
If you’re interested in an electric storage water heater, visit your electric provider’s website, or contact them to ask what they offer.
