Harvia Pro 20 Duo Steel Wood-Burning Sauna Stove
Dual Room Sauna Heater with Fireplace Function
The Harvia Pro 20 Duo Steel offers a unique dual-purpose design, allowing you to heat both your sauna and an adjacent room with a single wood-burning stove. Enjoy an authentic sauna experience while also creating a warm, fireplace-like atmosphere in the next room.
Built with durable stainless steel, this stove combines performance, versatility, and modern design, making it ideal for sauna users who want both functionality and comfort.
Wood-Burning Performance
The Harvia Pro Series stove delivers deep, radiant heat through direct wood combustion, creating an authentic sauna experience that electric heaters cannot replicate.
With 24.1kW of heating power, it efficiently heats sauna rooms ranging from 282 to 706 cubic feet while maintaining steady and long-lasting warmth.
Performance benefits include:
Fast and efficient heat-up
Deep, penetrating wood-fired heat
Consistent and even temperature distribution
Dual Room Heating Design
The Pro 20 Duo Steel is engineered to heat two spaces simultaneously, making it a practical solution for sauna and lounge areas.
Benefits include:
Heats sauna and adjacent room at the same time
Provides fireplace ambiance outside the sauna
Efficient use of a single heat source
Enhanced relaxation between sauna sessions
Stone Requirements and Heat Performance
This stove requires 88 lbs of sauna stones (2 boxes of 44 lbs, 10–15 cm stones), sold separately.
Sauna stones absorb and gradually release heat, creating a softer, more balanced temperature while improving steam quality and overall sauna comfort.
