Cut hot water heating costs with an energy-efficient electric 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 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 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.
Energy Saving Benefits
- Reduce standby heat loss to save money on your electricity bill
- Average annual savings on your electricity bill combined with the available incentive offsets the cost to upgrade to a high-efficiency model within first year
- Use less energy and avoid greenhouse gas emissions
- Reduce your home's carbon footprint
QualificationsElectric water heater
$50 customer incentive
- Unit must be on the Qualified Water Heater list at the time of purchase
- Qualifying units must be:
- 40-49.9 gallons with an Energy Factor, or EF, of 0.94 or higher
- 50-65.9 gallons with an EF of 0.95 or higher
- ≥ 66 gallons with and EF of 0.93 or higher
- Incentive Application must be postmarked within 90 days of purchase
- 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 lines
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.
