HUUM’s small rounded box: 3–5 cm / 1.2–2 in, 15 kg / 33 lb (534-BDL-STONES-XS-33). CLIFF and STEEL are built around this diameter — not the 5–10 cm DROP/HIVE rock, and not a 10–15 cm wood-stove chunk.
What size and where it goes
Rounded, 3–5 cm (1.2–2 in), one box 15 kg / 33 lb. From HUUM’s stones page: CLIFF about 75 kg (five boxes), CLIFF Mini about 60 kg (four), STEEL about 150 kg (ten), STEEL Mini about 60 kg (four). Do not put these in a Harvia KIP or a Cozy stove. Heater-only HUUM SKUs do not include stones; STU packages name stones — still confirm the carton with our team.
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.
