Cut hot water heating costs with an energy-efficient electric storage water heater.
After heating and cooling, water heating is the biggest use of energy in your home. From hot showers to dishwashing, a typical household spends an average of $500 per year on heating water! By installing a more energy-efficient electric storage water heater, you can cut that cost without cutting out daily showers.
Storage water heaters – the most common type – work by heating up water in an insulated tank. Heat is lost through the walls of the storage tank (standby heat loss), consuming energy even when you're not using hot water. New energy-efficient storage water heaters have higher levels of insulation around the tank, substantially reducing standby heat loss and saving you money. Because water heaters can fail with minimal warning, leaving you little time to research energy efficiency options, plan ahead and be prepared.
