Electric Storage Water Heaters

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 $400 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.

Not sure if your water heater is electric or gas? Here's how to tell:
    • First, read the label to see if it gives indication.
    • If you can't figure it out from the label, take a look at the pipes.
      • Gas water heaters will have 3 pipes: gas in, water in and water out. The gas line, often at the bottom of the unit, will have a shut-off valve on it. This differentiates it from an electrical conduit.
      • Electric water heaters will have 2 pipes: water in and water out with an electrical conduit or electrical wire feed line.

    Please note: Gas lines and electric wiring can be extremely dangerous. Be sure to contact a plumbing professional if you're unable to discern the type of water heating system in your home.
