The Harvia Legend 240 Duo Wood-Burning Sauna Stove & Fireplace Combo embodies the essence of an authentic sauna experience—rooted in tradition, yet elevated by contemporary innovation. Wrapped in a striking black steel frame, this masterfully crafted heater contains a remarkable quantity of stones that emit a deep, soothing heat. Even at lower temperatures, the generous stone mass delivers a consistently rich and enveloping warmth, maintaining the sauna's ambiance long after the fire begins to fade—making the Legend 240 Duo as efficient as it is refined.
At its heart lies a state-of-the-art fire chamber, engineered with a modern grate structure that expertly separates and channels combustion air. This intelligent airflow design directs part of the air to the upper section of the chamber, resulting in cleaner, more efficient burning and extending the stove’s durability. Compact safety clearances further enhance its practicality, allowing for greater freedom in sauna bench and interior design.
The Legend series is also designed with versatility in mind. The 240 Duo model supports a pipe-mounted water heater and features an innovative dual-fire capability, enabling you to heat the sauna from an adjacent room or even outdoors—preserving the tranquility of the space within. A reversible door and adjustable legs ensure ease of installation, while the timeless design and unmatched functionality make the Harvia Legend 240 Duo a distinguished choice for the discerning sauna enthusiast.

How to pile sauna heater stones?
The piling of the sauna stones has a great effect on both the safety and the heating capability of the heater, especially for electric heaters. Always check the right heater stone size and amount from the manual included with the heater. Smaller 5-10 cm diameter stones are usually used in electric heaters as they fit well between heating elements. Smaller stone sizes are also used on the top layer of woodburning heaters as they create more surfaces for steam generation. Larger 10-15 cm diameter stones are used in woodburning heaters and also in selected Harvia electric heaters with larger stone capacity.
Start the stone piling by washing off the dust from the stones before placing them into the heater. Be aware, that the type and the shape of the heater affect the piling structure of the stones. Your best guide for doing this properly for your selected heater is to follow the instructions included in the heater manual. Here are a few important tips for piling sauna heater stones for all Harvia heater types.
Piling Sauna Heater Stones:
- Do not drop stones into the heater
- Arrange the stones evenly and sparsely to make sure air can flow between the stones
- Do not form a high pile of stones on top of the heater
- Do not place stones on top of heater frame
- Place elongated stones vertically in the heater
Also notice that in electric heaters:
- Do not wedge stones between the heating elements
- Pile the stones so that they support each other instead of lying their weight on the heating elements
- Support the heating elements with stones so that the elements don’t bend
New stones may give the sauna a natural stone scent during the first heating. After piling the stones, we recommend heating the sauna and throwing enough water to douse all the heater stones. By doing this the unwanted stone scent will be dispersed after the first heating.
