The WIKING Luma 5 and WIKING Luma 6 design includes a heat store above the combustion chamber, making them the tallest models in the Luma series. The heat store can be filled with heat storage stones, which store heat from the stove and slowly release it into the room.
WIKING Luma 5 has wide side windows for better views of the flames, while WIKING Luma 6 has smooth steel sides. WIKING Luma 6 is also available with soapstone, sandstone or black, white or red tiles, giving the stove an attractive look.
