HUUM’s larger rounded box: 5–10 cm / 2–4 in, 15 kg / 33 lb (534-BDL-STONES-SM-33). This is the DROP, HIVE, HIVE Mini, CORE, and HUUM wood-stove size — not the 3–5 cm CLIFF/STEEL rock.
What size and where it goes
Rounded, 5–10 cm (2–4 in), one box 15 kg / 33 lb. HUUM stones page: DROP about 55 kg (four boxes), HIVE Mini 150 kg (ten), HIVE 250 kg (seventeen), CORE 40 kg (three), HIVE Wood 13 about 90 kg (six), HIVE Wood 17 about 135 kg (nine), HIVE Flow 150 kg (ten). HIVE Flow Mini is not given its own kg line on that page — do not guess it. Round stones only in a HUUM cage. Rinse, then pile with air gaps.
Before you pile
Rinse the rocks in a tub or with a hose before they go in the heater. Factory dust will smell on the first heat if you skip it. Pile loose so air can move — a jammed cage cooks elements and kills löyly. Cover the elements on an electric; do not rest a boulder on a bend in the coil.

FAQ
Are these a full pallet?
No. One box. We do not import Prosaunas full pallets.
Is a heater in this carton?
No. Stones only.
Do I need to rinse them?
Yes. Wash the dust off before you pile.
Which size for my heater?
5–10 cm for most electric wall heaters. 10–15 cm for wood stoves and large floor electrics. HUUM CLIFF/STEEL want 3–5 cm; DROP/HIVE/CORE and HUUM wood want 5–10 cm. If the manual disagrees with a rule of thumb, the manual wins.
