DOE estimates that this efficiency improvement, and the resulting lower gas bills, would save consumers $1.9 billion annually — or $500 over the lifetime of each new furnace.
The DOE implemented efficiency regulations to prohibit new non-condensing gas furnaces by 2028, by requiring that non-weatherized gas furnaces achieve an annual fuel utilization efficiency of 95%.
The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
In all, the higher heating value of hydrogen is 18.2% above its lower heating value (142 MJ/kg vs. 120 MJ/kg). For hydrocarbons, the difference depends on the hydrogen content of the fuel. For gasoline and diesel the higher heating value exceeds the lower heating value by about 10% and 7%, respectively, and for natural gas about 11%.
On average over the years, [clarification needed] boiler combustion efficiency has risen from 80% to more than 95%. The efficiency of heat produced is directly linked to boiler efficiency. The percentage of excess air and the temperature of the combustion products are two key variables in evaluating this efficiency.
AFUE = furnace efficiency ≈ 95% for a modern condensing furnace; COP = heat pump coefficient of performance ≈ 3.2 seasonally adjusted for northern US heat pump; EI = emissions intensity of electricity ≈ 200–800 ton(CO 2)/GWh, depending on the region's mix of electric power plants (Coal vs Natural Gas vs Nuclear, Hydro, Wind & Solar)
