Keeping a mid-sized RV comfortably warm takes real heating capacity, and this Dometic DFMD30111 delivers 30,000 BTUs to do exactly that. The heat exchanger's design style is built to maximize air distribution, spreading warm air more evenly through the coach instead of leaving pockets of hot and cold as it heats.
It also runs quieter than you'd expect from a furnace this size, thanks to a design that reduces air turbulence during operation. The low-profile, compact footprint (7-3/8" x 16-1/2" x 20") installs in either a horizontal or vertical configuration, so it fits into tighter furnace bays without giving up heating performance. It's a 12V DC powered unit engineered for easier long-term maintenance, and a stamped steel door is available separately for select models.
Confirm your existing furnace bay dimensions and BTU needs before ordering, and check whether your installation requires the separately sold door kit.
