Please verify the stone requirements for your specific Harvia heater before ordering.

Stones should be stacked loosely to allow proper airflow between the heating elements, ensuring efficient heating and extending heater life. As a natural material, each stone will vary slightly in shape, size, and appearance.

Because they are a natural product, variations in size, shape, texture, and color are expected and are not considered manufacturing defects. Stones should be inspected periodically and replaced as needed to maintain optimal heater performance.
