## Long description

Harvia Vulcanite sauna stones are premium-grade volcanic rocks specifically selected for their durability and thermal performance in both electric and wood-burning sauna heaters. With a size range of 5-10 cm, these stones are engineered to withstand extreme temperature fluctuations while maintaining structural integrity. The 20 kg package provides sufficient volume for most standard sauna stoves, ensuring consistent heat storage and efficient steam generation for an authentic sauna experience.
Advantages
The primary benefit of Harvia Vulcanite stones is their exceptional heat retention capacity, which allows for a steady and even release of warmth throughout the sauna cabin. Due to their high compression resistance and ability to withstand temperatures up to 1400 °C, these stones offer a significantly longer service life compared to standard alternatives. Their natural composition ensures that they do not release harmful substances when heated, providing a clean and safe environment for relaxation.
Suitable for
Electric sauna heaters
Wood-burning sauna stoves
Residential sauna cabins
Commercial sauna facilities
When it may not be suitable
These stones are not recommended for very small, compact heaters that require smaller stone sizes, as the 5-10 cm diameter may not fit properly in narrow heating elements. Additionally, they should not be used in non-sauna heating applications or industrial furnaces where specific chemical resistance or different thermal expansion properties are required.

How to use
Before placing the stones in the heater, it is recommended to rinse them with water to remove any dust or debris accumulated during transport. Arrange the stones in the heater compartment, starting with the largest ones at the bottom and filling the gaps with smaller stones. Ensure that the stones are not packed too tightly, as this can restrict airflow and lead to overheating of the heating elements. For wood-burning stoves, ensure the stones cover the heating surface completely to protect the metal from direct flame contact.
What to consider before purchase
Check the manufacturer's manual for your specific heater to ensure the 5-10 cm size is compatible.
Calculate the total weight capacity of your heater to avoid overloading.
Ensure the heater compartment is clean before installing new stones.
Usage recommendations: To maintain optimal performance, it is advised to re-stack and inspect the stones at least once a year. Remove any stones that have started to crumble or break down to ensure efficient airflow and prevent damage to the heating elements.
