looks like the form isnt updated correctly then, yes it should be 26%  @IntuitGabi  this needs to be addressed

Biomass stoves burn biomass fuel to heat a home or heat water. Biomass fuel includes agricultural crops and trees, wood and wood waste and residues (including wood pellets), plants (including acquating plants), grasses, residues, and fibers.

**New for 2021:

Beginning in 2021, if you purchase and install a wood or pellet stove or larger residential biomass heating system with a Thermal Efficiency Rating of at least 75%, you will be able to claim a credit that is uncapped and based on the full cost (purchase and installation) of the unit, in the amount of:

• 26% for systems placed in service between 01/01/2021 through 12/31/2022
• 22% for systems placed in service between 01/01/2023 and 12/31/2023.

The credit must be claimed on the tax return for the year the product installation is completed.
