On August 16th, 2022, the Inflation Reduction Act of 2022 was passed, naming CEE tiers as the basis for federal tax credits across several product categories through 2032. The Act cites products “which meet or exceed the highest efficiency tier (not including any advanced tier)”.

  • Furnaces and Boilers
  • Water Heaters (Electric)
