Morsø 6140 Convection Wood Stove

The Morsø 6140 is a cast iron wood stove built around soft curves and clean, simple lines. It sits on a low base at just under 30 inches tall. It's the kind of stove that looks at home in a modern space and still feels warm and familiar.

It's a convection stove, and it burns wood only. Pre-heated combustion air, an airwash for the glass, and tertiary air are all part of the design. The 6140 is certified to the EPA 2020 standard at 1.8 grams per hour, with 74% HHV efficiency, and it takes logs up to 12 inches long.

What Makes the Morsø 6140 Different

• Sculpted cast iron. The curved cast iron body gives the 6140 a soft, finished look from every side of the room.
• Low base. Sitting on a low base keeps the stove compact in height and puts the flames at a comfortable viewing level.
• Convection design. A convection system is built into the stove, part of how Morsø designed the 6100 series to move heat into the room.
• Clean view of the fire. Pre-heated combustion air and an airwash system work to keep the burn clean and the glass clear.

Ownership & Maintenance

An ash tray makes cleanout simple, and the airwash system helps keep the glass clear, though any wood stove glass needs a wipe now and then. Gaskets and firebox parts wear with use over the years. We offer ongoing service for our customers.
