Harvia rounded 5–10 cm in the 15 kg / 33 lb white box (R-991). Smaller rounded rock for electric cages. Water slips past the top layer instead of flashing off one flat face.
What size and where it goes
Rounded, 5–10 cm (2–4 in), one box 15 kg / 33 lb. Electric heaters that take 5–10 cm. Harvia still wants angular rock in the bottom of a small cage. This is also the diameter HUUM DROP / HIVE / CORE want — if you want a Harvia-branded 5–10 rounded box next to a HUUM heater, this is the Harvia SKU; HUUM’s own 15 kg box is 534-BDL-STONES-SM-33.
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.
