 | After home heating, hot water is the second largest user of heating energy in your home – accounting for 15 percent of your total energy use. Replacing your water heater when you upgrade your heating system, or before it leaks, will save you time and money. Ask your dealer, plumber or retailer for a natural gas water heater that will qualify for a rebate and fit your household needs. |
For new construction or replacement of natural gas water heater
| type of natural gas water heater | Energy factor | Rebate |
| Storage tank (40 gallons or more) | .62 or greater EF | $50 |
| Storage tank (less than 40 gallons) | .64 or greater EF | $50 |
| Tankless | .80 or greater EF | $250 |
For replacement of electric resistance water heater with natural gas*
| type of natural gas water heater | energy factor | Rebate |
| Storage tank (40 gallons or more) | .62 or greater EF | $900 |
| Storage tank (less than 40 gallons) | .64 or greater EF | $900 |
| Tankless | .80 or greater EF | $900 |
*CenterPoint Energy will examine natural gas usage history to confirm eligibility for electric replacement rebate levels.
Note: Ratings will be determined by referencing the Air-Conditioning, Heating and Refrigeration Institute (AHRI) and how the piece of equipment is rated in their directory.
Energy factor (EF) is the ratio of useful energy output from the water heater to the total amount of energy delivered to the water heater.
Atmospheric - vent
These are the standard gas water heaters that have been serving millions of homeowners for years. They use room air for combustion and exhaust. The exhaust chimney is installed to a draft hood that sits slightly above the tank. These water heaters use "gravity" (rising warm air) to exhaust combustion byproducts and are vented through the roof. Typically the exhaust vent is connected to the furnace vent and they share the same chimney.
Direct-vent
Direct-vent units use no room air at all. Direct-vent water heaters are particularly good for tight construction because they use outside air versus room air for both combustion and exhaust, so they operate independently of other exhaust systems in the house.
Power-vent
These water heaters are the same as the atmospheric models but with a reengineered exhaust system. This unit offers all the benefits of natural gas, plus flexible installation. It requires no chimney, chase, or flue. Because of the power-assisted exhaust, it can be placed up to 40 feet from where it is vented through a sidewall, making it easy to fit in even the most cramped equipment rooms.
Powered direct-vent
A hybrid, this model combines the features of power- and direct-vent models. It's perfect for airtight construction and offers flexible installation.
Tankless water heaterscan be an efficient technology for home water heating, but due to their design, tankless water heaters have high natural gas usage requirements (BTU/hour input) compared to tank-style water heaters. The additional load on our system from tankless water heaters results in undesirable capacity demands during peak daily use periods. We do not offer a rebate on this technology.
Program Basics
Rebates are rewarded on a first-come, first-serve basis until funds are depleted. Rebate program funds are budgeted on an annual basis. Rebate amounts and availability are subject to approval by the Oklahoma Corporation Commission.
How the program works
