These furnaces can achieve AFUE ratings as high as 97 percent. Pulse furnaces burn natural gas in small pulses, much like a car engine, allowing maximum heat to be extracted from the fuel.The exhaust gases from a condensing furnace are cool enough that they can be vented through a wall with plastic piping. Condensing furnaces recapture some of the heat from water vapor, which is wasted by traditional furnaces.Electronic spark ignitions or "hot surface" ignitions eliminate the need for continuously burning pilot lights that waste fuel and increase operating costs.Look for these high-tech features that improve furnace efficiency: New residential furnaces will display an EnergyGuide label comparing the annual fuel costs of similar-sized units. The higher the AFUE, the more efficient the unit and the more money you can save. Most new high-efficiency furnaces have an Annual Fuel Utilization Efficiency (AFUE) rating of 90 percent or higher. Air from a natural gas furnace is up to 25 degrees warmer when it comes through the vent than air from an electric heat pump. Natural gas furnaces heat your home faster.
