Black vulcanite sauna heater stone is a small granular, dark grey stone. When wet, the stone shines black making it a great-looking option with selected Harvia heaters. The stone’s volcanic origins date back to ca. 2000 million years. Based on its structure and composition, vulcanite is a good choice for a sauna stone as it is hard and durable.
Features:
- Stylish vulcanite sauna heater stone. Shines black when wet.
- For electric heaters and as a top stone for wood burning heaters
- Split-face stones store plenty of heat, making the water thrown onto them vaporize efficiently on the broad fracture surface
- The split-face stones are easy to stack and enable good air circulation
- Excellent resistance to heat fluctuations and thermal conductivity. Good stone gravity and heat storage capacity.
- Color and stone species: Black Vulcanite
- Stone size 5cm (1-2") and box weight 20kg (44lb)

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.
