Innovative Heat Exchange Technology
Dometic’s tubular pipe design heat exchanger stands out with smooth, rounded bends that allow for better airflow. This advanced design ensures even heating by preventing air from being trapped or slowed down in sharp corners. The result is superior air circulation and more consistent heat distribution.

• Door Required: The furnace requires an exterior access door (sold separately)for installation.
