Description

Harvia Legend 300DUO is a wood-burning sauna heater with a fireplace-style DUO setup, delivering 23.5 kW of heat output in a black steel build designed for 15–30 m³ sauna rooms. Built to heat the sauna from an adjacent room (or outside the sauna space), it’s made for owners who want a traditional wood-fired atmosphere paired with practical day-to-day use.

The Legend 300DUO’s signature look comes from its steel frame filled with sauna stones, creating a stone-rich heat source that supports a steady sauna feel even as the fire naturally cycles. Inside the fire chamber, an engineered grate structure separates combustion air and directs part of the airflow to the upper section of the chamber to support a cleaner, more efficient burn. The heater is built for floor installation and includes adjustable legs to help with placement. For installation flexibility, the door opening direction can be changed, helping you align the firebox and access with your layout.

Stone capacity and sizing are central to how the Legend 300DUO performs. This model is specified for a 260 kg stone amount using Ø10–15 cm stones. Sauna stones are required for use and are not included with the heater. With the stones properly loaded, the heater’s stone mass supports a consistent heat feel that fits both medium and larger residential sauna rooms within the stated volume range.

NOTE: This heater requires a minimum of 572 lbs of sauna stones (13 boxes). To select yours click the button 'Bundle & Upgrade'

What arrives in the box is focused on the core heater assembly and essentials. The listed content of delivery includes the heater, glass door, ash box, grill, and installation and operating instructions. Once paired with the required stones and correctly installed with appropriate clearances, the Legend 300DUO is built for an interior sauna environment and is marked with CE and EAC certifications as listed for the model.

About the brand: Harvia designs sauna heating products with a focus on practical installation, safe operation, and long-term household use. The Legend line emphasizes a stone-forward heater design paired with functional details—like adjustable footing and configurable door swing—intended to make wood-fired sauna ownership more straightforward while keeping the traditional sauna feel.

Why Choose Harvia?

The Legend 300DUO is built for sauna owners who want wood-fired heat while keeping the fire-loading side outside the sauna space. Its DUO configuration supports that layout goal, while the stone-heavy frame design emphasizes the kind of heat feel many people associate with traditional sauna use.
At the product level, the technical design focuses on practical performance: a combustion-air grate structure intended to support cleaner burning, a specified stone load for consistent heat character, and placement helpers like adjustable legs and a reversible door swing to better match real-world build layouts.
At the brand level, Harvia’s approach centers on household sauna use with clear model-level technical data and install considerations. For long-term ownership, the Legend ecosystem also supports add-on compatibility (such as a pipe-mounted water heater) when that’s part of your planned setup.
