The industry standard (ANSI Z21.47) requires all furnace manufactures to test heat exchangers to 10,000 cycles. Amana wanted more. At least 100 times more!
Amana's revolutionary Million-Air stainless steel heat exchanger has gone beyond one million cycles. And the Million-Air is still running without any sign of failure. That means igniting the burner, heating the exchanger to 1,100 F and allowing it to cool to 200 F. Then repeating the process more than one million times! A million cycles can equate to a century of use under normal operating conditions and maintenance.The Million-Air draws on three key technologies that work together with the physical properties of the stainless steel tubes. The result is a tight, strong, long-lasting heat exchanger that is unsurpassed in the industry.
...the bottom line... unlike warrantys that provide a replacement heat exchanger for a fixed period of time, the Million-Air Stainless Steel Heat Exchanger blows all previous warranties out of the water with a...
Lifetime Replacement of the Entire Furnace if the Heat Exchanger Fails!
