Why HUUM uses rounded stones

Rounded stones complement HUUM’s open baskets, leave useful air paths, and create a broad surface for water. The correct size and quantity are model-specific: DROP uses four boxes; HIVE Mini ten; full HIVE sixteen; HIVE Wood six or nine; HIVE Flow seven or ten. CLIFF and STEEL use the smaller 1 to 2-inch size instead.

Care

Wash stones before loading, keep them loose enough for airflow, cover the elements, and repack the bed at least annually. Replace cracked or crumbling stones rather than forcing them back into the heater.
