Energy Dept. Proposes Reversal Of Trump-Era Furnace Efficiency Rollback [1]
"The Energy Department on Wednesday proposed reversing a Trump-era rule that was expected to undermine its ability to regulate efficiency of both residential furnaces and commercial water heaters.
The Trump administration’s rule — completed five days before President Biden's inauguration — was expected to keep inefficient heaters on the market for more time by dividing up the heaters into two categories based on how they’re vented.
By creating a new class of products for furnaces that had a type of venting known as noncondensing venting, these furnaces would need to be regulated separately and could not be entirely phased out."
