Kratki MB 120 G 31kW Wood Fireplace
The Kratki MB 120 G is a large, high-output built-in wood-burning fireplace designed for substantial spaces. With a 31kW heat output, it is the most powerful wood-burning fireplace available in South Africa.
The MB 120 G combines a wide panoramic fire view with a modern steel construction and a rise-and-fall glass door. Its substantial 120 cm-class firebox creates an impressive centrepiece while providing high levels of heat from seasoned firewood.
Powerful 31kW Wood-Burning Fireplace
The Kratki MB 120 G is specified with a 31kW heat output and a heating capacity of approximately 280–700m³. This makes it particularly suited to large residential spaces and other substantial areas requiring high heat output.
The fireplace uses seasoned wood as its fuel and has an 80% efficiency rating.
For large open-plan homes, expansive living areas and properties requiring significant heating capacity, the MB 120 G provides an exceptionally high-output fireplace solution.
Wide Panoramic Fire View
A key feature of the MB 120 G is its large glass viewing area. The rise-and-fall door provides a clear panoramic view of the fire while maintaining the benefits of a closed-combustion fireplace during operation.
The door can be raised for loading wood and lowered for normal burning. The fireplace also incorporates an air-wash system designed to help reduce soot deposits on the glass.
Steel Construction and Heat-Intensifying Lining
The MB 120 G is manufactured from high-quality steel designed to withstand high operating temperatures. The combustion chamber is lined with Kratki’s heat-intensifying ceramic material.
The combustion chamber lining helps retain and intensify heat within the firebox. The fireplace also uses primary, secondary and tertiary combustion technology.
Efficient Closed-Combustion Heating
The MB 120 G is a closed-combustion wood fireplace designed to use the heat produced by burning wood efficiently.
Its combustion technology combines primary, secondary and tertiary combustion, while natural convection and radiant heat transfer contribute to distributing heat from the fireplace.
The result is a high-output fireplace designed for efficient wood burning and substantial heat delivery.
Designed for Large Spaces
With its 31kW heat output and heating capacity of 280–700m³, the Kratki MB 120 G is intended for considerably larger spaces than many standard residential fireplaces.
Correct sizing remains essential. The required fireplace output depends on factors such as room volume, insulation, glazing, building design and climate. Professional assessment should therefore be carried out before installation.
