American’s ADAPT™ premium condensing gas tankless water heaters deliver robust, on-demand performance and the flexibility to install in practically any residential setting. Easily add scale prevention protection by replacing the bypass cartridge with an optional X3 cartridge sold separately — which can make the heat exchanger last up to three times longer than a standard tankless water heater while maintaining like-new performance.
Please watch all Premium Condensing Tankless videos on the page before completing the certification test.
