If your water heater is more than 10 years old, think about replacing it with a high-efficiency heat pump water heater (2.5 EF or greater, 50 gallon maximum), or consider installing a high-efficiency model in new construction. You'll save energy and dollars and also improve the efficiency of your water heating system by reducing tank loss and improving recovery time.
