Natural Gas/Propane Furnaces
Furnaces heat and circulate warm air in the winter. . The efficiency of new furnaces is measured by the annual fuel utilization efficiency (AFUE), a measure of seasonal performance. Furnaces today are between 80% AFUE and 98% AFUE. Traditional "power combustion" furnaces are 80-82% AFUE. Above 90% AFUE, a furnace is "condensing," which means it recaptures some of the heat wasted in traditional systems by condensing escaping water vapor. Consider the following when selecting a new furnace:
- Condensing Models
Wisconsin Fuel strongly recommends a condensing furnace (AFUE 90% or higher) for the area we service. - High Electrical Efficiency.
A furnace can use a significant amount of electricity, mostly to power the fan motor. Variable speed fan motors are generally more efficient than standard (“PSC”) motors and may save you hundreds of dollars per year. Wisconsin Fuel sells several models that use a variable speed fan motor. - Proper Sizing
Make sure the heating capacity of the furnace is not too high for your home. Most furnaces are substantially oversized.
