Wood-Burning Performance
The Harvia Pro Series stove delivers deep, radiant heat through direct wood combustion, creating a more natural and immersive sauna experience compared to electric heaters.

Performance benefits include:
- Fast and efficient heat-up
- Deep, penetrating wood-fired warmth
- Stable and even heat distribution
Built-In Water Tank for Added Convenience
The integrated 30-liter water tank allows you to heat water alongside your sauna session, making it especially useful for off-grid or cottage environments.

- Convenient access to heated water

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 store heat, then release it gradually to create a softer and more balanced temperature. High-quality stones improve heat retention, steam production, and overall durability.
