New Furnace Efficiency Law

A plan was announced on June 13 by the Biden Administration for non-condensing indoor gas furnaces to be phased out by 2029. The proposal from the Department of Energy (DOE), if adopted, would require new non-weatherized gas furnaces to have an annual fuel utilization efficiencies of at least 95%, meaning they would have to produce at least 95 Btu of heat for every 100 Btu of natural gas consumed. That would ban non-condensing furnaces, which currently must be at least 80% efficient, and is intended to steer consumers toward more efficient technology, like condensing furnaces, which capture additional heat from exhaust gases.
