GAS FURNACE
Ever since the Pulse gas furnace was introduced in 1982, it has continually set the standard for excellence in gas furnaces. In fact, the Lennox Pulse furnace design earned the U.S. Department of Energy Special Award for Energy Innovation.
And now, the Pulse21 gas furnace offers more than ever before, with its built-in WatchGuard™ circuit, an insulated blower compartment, a simple and efficient filter assembly and a host of other features designed to make is safer, quieter, easier to use and more efficient.
The Pulse21 benefits of safety features such as the spark igniter which eliminates the exposed flame of a pilot light. The automatic shut-down feature ensures 100% gas shut-off in the event of a blocked flue or any other abnormal operating conditions and monitors the furnace operation to provide reliable comfort over a wide range of conditions, eliminating the need for unnecessary service calls. Because the Pulse21 furnace uses only outdoor air for combustion, it also reduces the corrosive effects of indoor air on your furnace.
The Pulse21 gas furnace is backed by a 5-year limited warranty on parts and a Lifetime Limited Warranty on the heat exchanger assembly and condenser coil. That's a promise of quality no other manufacturer can beat.
All furnaces are rated against strict government and industry standards to determine how much heat they generate for every dollar you spend on fuel. The rating for heating performance is called "AFUE" which stands for Annual Fuel Utilization Efficiency. The higher the rating number, the more efficiently the system operates and the less you'll spend on your home utility bills.
With its 96.2% AFUE rating, the Lennox Pulse21 gas furnace uses up to 96.2 cents out of every heating dollar you spend to actually heat your home. That makes it one of the most energy efficient furnaces on the market today - much more efficient even than furnaces installed as recently as five years ago. This means you can enjoy lower energy bills and recoup your equipment cost more quickly.
