Traditional Wood-Fired Sauna Heater with Front Water Tank
The Harvia Pro 20 ES is designed for sauna users who want a traditional wood-burning experience with added practicality. It features a built-in 20-liter water tank positioned at the front of the stove, allowing you to conveniently heat water during your sauna session.
Perfect for cottages, cabins, and outdoor saunas, this model combines authentic Finnish performance with functional design. Its large stone capacity ensures consistent heat and a rich, steady steam experience.
Wood-Burning Performance
The Harvia Pro Series stove delivers deep, radiant heat through direct wood combustion, creating a natural and immersive sauna environment that electric heaters cannot replicate.
With 24.1kW of heating power, it efficiently heats sauna rooms ranging from 283 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
Front Water Tank for Convenience
The integrated 20-liter front-mounted water tank allows for easy access to heated water during your sauna session, making it ideal for off-grid and traditional sauna setups.
Benefits include:
Convenient front access to hot water
Dual functionality for heating and water use
Enhanced traditional sauna experience
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 store and radiate heat gradually, helping create a softer, more balanced temperature while improving steam quality and overall performance.
