The Napoleon Ultimate 9700 Series Gas Furnace is the most stylish in the industry and will meet all your heating needs. The two-stage system creates a consistent, comfortable temperature throughout your home. The furnace will operate on the first, low fire stage for greater efficiency and comfort for most of the heating season. On colder days, the furnace automatically switches to the high fire, second stage to produce additional heat for your home. This effective two-stage system is like having two furnaces in one. Napoleon’s superior engineering and design guarantees reliable and efficient heat for years to come. With the Ultimate 9700 Series furnace, you’ll forget it’s winter.
AFUE works much like the miles-per-gallon rating on a car – the higher the rating, the lower the fuel costs. The Annual Fuel Utilization Efficiency (AFUE) measures the amount of comfort for every dollar spent. If a furnace is 25 years old or more, it could have a rating as low as 55% to 65% AFUE, compared to a new Napoleon Ultimate 9700 Series’ 97%.
