Hwam is a Danish company that manufactures advanced-technology, architect-designed wood-burning stoves. Hwam's patented Automatic™ system ensures optimal combustion through the automatic regulation of air input.

 

The Hwam Vivaldi, shown here, is small (4.5 kW), efficient stove, designed by architect Anders C. Fasterholdt, which is a good choice for smaller living rooms and weekend cottages. The company also makes larger wood-burning stoves, inserts, a pellet stove, and water-tank stoves.
