Sauna stones (or pebbles) are an essential component of the sauna experience. Hot rocks raise the ambient temperature and produce a nice vapor when water is put on them. Instead of heating metal and other things, the goal is to heat as many pebbles as possible and keep them hot. A sauna room's good heat is provided by stones, while radiation heat is provided by hot metal.
There are a variety of stones to choose from. On any sauna heater or stove, we only advocate using appropriate stones. In terms of business, this means that the stones must be labeled as sauna stones on the package. It is critical that they are long-lasting and do not break too easily. If the sauna is utilized on a weekly basis, the rocks should be replaced once a year. Pick two rocks and knock them against each other to see if they're in good form. It's time to replace them if they crack. They must also be cleaned, as dust might otherwise come into touch with the heater.
Smaller stones (5–10 cm) are recommended for electrical sauna warmers, whereas larger stones (10–15 cm) are recommended for wood-burning sauna stoves. The stone can be olivine diabase, which is the most common, or vulcanite, which has a deeper tone.
Only use ceramic stones in Aitokiuas stoves with the fire in close contact with the stones. Rounded and white stones are solely used for decoration, and any sort of stone can be used as the top layer. Standard stones will be used in their stead (in contact with heating elements or fireplace).
