WIKING Luma 4 Wood Burning Stove — Wide-View Design with Intelligent 7kW Performance
The WIKING Luma 4 wood burning stove delivers powerful 7kW heat output while offering a broader, more expansive design that enhances flame visibility. Designers at HWAM engineered it to combine advanced Danish performance with clean, modern styling. As a result, it provides efficient and controlled heating with minimal effort.
Moreover, with an A+ energy efficiency rating and 81% efficiency, the Luma 4 balances performance with environmental responsibility. At the same time, its wider proportions create a bold focal point. Therefore, it fits perfectly within contemporary interiors while maintaining a refined appearance.
WIKING® Automatic™ — Precision Combustion Without the Effort
The WIKING® Automatic™ system regulates airflow during lighting and re-stoking. Because of this, the fire burns under optimal conditions without constant manual adjustment.
As a result, the stove improves fuel efficiency and reduces emissions. In addition, it maintains a consistently clean burn. Consequently, you enjoy steady heat output and a clear, attractive flame with minimal effort.
Combustion Air System — Consistent Airflow for Clean Burning
Efficient combustion requires a steady oxygen supply. For this reason, the WIKING Luma 4 supports an external combustion air connection.
This feature proves especially useful in modern, airtight homes where internal airflow is limited. Because of this, the stove maintains balanced airflow throughout operation. As a result, it delivers cleaner combustion and supports overall indoor comfort.
Broader Design with Enhanced Flame Visibility
The Luma 4 features an increased width and a slightly taller profile. Therefore, it provides an enhanced and more immersive view of the fire.
In addition, the larger front aspect allows the flames to become a central feature in the room. As a result, it works especially well in open-plan living spaces. However, despite its larger presence, the stove remains well-proportioned. Consequently, it integrates seamlessly into a wide range of interiors.
Engineered for Safe, Flexible Installation
The WIKING Luma 4 offers flexible installation options for different home layouts. For example, it supports both rear and bottom external air connections.
Because of this, installation becomes straightforward and adaptable. In addition, clearly defined clearance distances and compatibility with various flue systems simplify the process further. Therefore, installers can integrate the stove with confidence.
Overall, the Luma 4 meets strict standards, including EN 16510, Ecodesign, DEFRA, and BImSchV Stufe 2. Ultimately, it delivers low-emission, reliable, and future-ready heating for modern living spaces.
