Know before you buy
These stones are sized and shaped to fit the specific wire cage designs of HUUM heaters. Their rounded form ensures proper airflow between the stones, which is essential for the heater's performance and longevity.
The rounded shape allows for a more gradual release of steam compared to jagged, crushed stones. This creates a softer, more consistent heat that feels less sharp or aggressive during your sauna session.
Olivine diabase is a high-density volcanic rock known for its exceptional heat retention and ability to withstand extreme temperature fluctuations without cracking. It is the industry standard for sauna heaters because it effectively absorbs and radiates heat over long periods.
The number of boxes depends on your specific HUUM heater model, as each unit has a different stone capacity. You should check your heater's manual to determine the total weight required to fill the chamber properly.
Yes, it is recommended to rinse the stones with water before installation to remove any dust or debris from the packaging. This prevents dust from burning off and creating an odor during your first sauna use.
