Open Range products have a unique and incredible heating system. We start with a 4 inch heat duct from the furnace down to the underbelly in place of the 2 inch some of the competitors use. All of our tanks are suspended between the I beams in the underbelly allowing us to have forced air heat blowing from the 4 inch heat duct surrounding the tanks with warm air flow.
How do we get the air flow? Simply by having a return at the end of the tanks going back into the coach. The secret is that simple. We put a return in the underbelly that allows for continuous airflow around the suspended tanks. Other brands don’t have a return system and that causes static pressure to build up, not allowing proper airflow around the tanks.
