Open Range products have a unique and incredible heating system. We start with a 4 inch heat duct from the furnace down the 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 their underbelly to allow air flow over the tanks instead of a pressurizing system that occurs in other brands.
Open Range products are built to withstand the harshest of environments. We put our products into a zero degree chamber for five hours with thermometers placed in key areas throughout the unit.
