Experience the ultimate convenience of heating your sauna without ever disrupting your relaxation inside the steam room. The Harvia Pro 20 SL features an ingenious exterior feed system that allows you to load firewood from an adjacent room or outside wall, effectively keeping your sauna space free of ash and wood debris. This dual-function design transforms your changing room into a cozy lounge with the ambiance of a glass-door fireplace, while the other side powers a world-class sauna session.

Built for serious heat enthusiasts, this cast-iron powerhouse generates an impressive 24.1 KW output to effortlessly warm medium to large saunas ranging from 283 to 706 cubic feet. The stove is engineered to maximize air circulation, ensuring that when you ladle water onto the stones, you are greeted with a soft, consistent "löyly" steam that penetrates deep into your muscles. It delivers the authentic, robust heat that only a true wood-burning unit can provide, making every session feel like a professional spa treatment.

Durability and flexibility meet in this expertly crafted unit, designed to withstand the intense thermal cycles of daily use. The adjustable door direction allows you to customize the installation to fit the specific layout of your home or cabin, ensuring seamless integration into your space. With a massive stone capacity, this stove retains heat for hours, allowing you to linger longer in the warmth and dry out the room efficiently once you are finished.

  • Maintain an uninterrupted state of deep relaxation by feeding the fire from an external room, ensuring your sauna session remains peaceful, clean, and free of smoke or debris.
  • Create a warm, inviting atmosphere in your dressing area or patio where guests can enjoy the visual comfort of a crackling fireplace while the sauna reaches optimal temperature.
  • Experience the invigorating health benefits of intense, evenly distributed heat that works to detoxify your body, improve circulation, and soothe tired muscles after physical activity.

FEATURES

  • The Harvia 20 SL combines the benefits of a sauna heater and a fireplace, allowing you to enjoy the warmth in two rooms simultaneously. Perfect for creating a cozy, inviting atmosphere while you relax and unwind.
  • The stove's door direction can be easily adjusted, making it simple to use and fit into your sauna space. This feature enhances convenience, ensuring you can comfortably add wood from another room.
  • With a powerful 24.1 KW output, the Harvia 20 SL efficiently heats sauna rooms ranging from 283 to 706 cubic feet. This ensures a consistent and enjoyable sauna experience every time.
  • Features both upper and rear connection openings along with a soot opening, offering flexibility in installation. This design allows for a customized setup that suits your specific sauna needs.
  • Requires a minimum of 88 lbs of sauna stones, which are sold separately. For optimal performance and quality, consider purchasing additional stones to ensure the best fit and function.
