The Harvia Pro 20 DUO is built to combine sauna performance with enhanced usability and design flexibility. Its through-wall structure allows firewood to be loaded and ash to be removed from outside the sauna, helping maintain a cleaner and more comfortable interior environment.
The DUO configuration also opens up more possibilities for sauna bench layout by freeing up internal space that would otherwise be occupied by the firebox. A pipe connection on top (115 mm) supports efficient chimney integration, while the adjustable feet ensure stable installation and proper alignment of the chimney opening.
With its stainless steel exterior and large glass hatch, the heater creates a visually appealing focal point in the adjoining room while delivering reliable heat and steam performance for the sauna itself. A separate chimney-mounted water tank can also be added for increased functionality.
