Program details

How it works

Decatur Utilities (DU) offers rebates for clean, efficient natural gas appliances. The public page says these rebates are available for new and existing homes, with one exception: the additional conversion incentive is specifically separate from the regular rebate list.

What the money covers

The page lists rebates for several natural gas appliances and related equipment:

  • Water Heater (Tank)
    • Up to $200 if retaining a natural gas water heater
    • Up to $400 if converting from electricity to natural gas
  • Water Heater (Tankless)
    • Up to $300 if retaining a natural gas water heater
    • Up to $500 if converting from electricity to natural gas
  • Furnace: $250
  • Natural Gas logs: $50
  • Standard or Commercial range: $100
  • Clothes Dryer: $150
  • Two-mantle Light: $50
  • Open Flame Light: $50

Amounts and matching

The page does not mention income-based pricing or match percentages. The highest stated rebate is up to $500 for a tankless water-heater conversion from electricity to natural gas. The page also says rebates are limited to up to two of the listed water-heater rebates.

Service line and installation details

If you do not already have natural gas service, DU says it will install the natural gas service line for your home at no charge, up to 300 feet. A certified natural gas plumber must install the internal piping and appliances.

How to apply

Homeowners can apply over the phone at 256-552-1400 Opt 4 or by email at csr@decaturutilities.com. The page also instructs customers to call DU Customer Service to verify that natural gas is available at their address.

Timing and deadlines

The page states that the conversion incentive is extended to 12/31/26. No other public deadline is provided.
