Current English installation and operation manual – COZY 12 and COZY 18
Cozy Heat 12 and 18 installation and operation manual. Cozy Heat current manufacturer site.
The OG silhouette is what earns its place in the room. The OG pinches and flares its vertical guard around a broad face of stone. It feels more sculptural than the mesh models without hiding the firebox or turning the heater into decoration.
The package uses the same Cozy structural-steel firebox walls about 67% thicker than a typical standard-stove wall and clean, precise welds as the heater-only listing. Its three-path combustion uses about 25% less wood than comparable heaters, while the fire still lights, regulates, and refuels like a familiar wood stove.
Choose the stove before the finish
Every option pairs the exact Cozy Heat OG heater with the package’s current stone-box count. Split-face stones give the cage a rougher, more architectural texture. Rounded stones make the visible field feel softer. Both choices are olivine diabase; the difference shown here is shape and appearance, not a promise that one produces better steam.
On a phone, swipe the table sideways to compare every column.
| Package option | Stone boxes | Manufacturer stone mass |
|---|---|---|
| 12 kW + split-face stones | 4 boxes | 265 lb required by the current model drawing |
| 12 kW + rounded stones | 4 boxes | 265 lb required by the current model drawing |
| 18 kW + split-face stones | 6 boxes | 353 lb required by the current model drawing |
| 18 kW + rounded stones | 6 boxes | 353 lb required by the current model drawing |
The table separates the package box count from the heater’s technical stone load. Stone size and packing change the final weight inside the cage, so follow the exact manual and keep the stove body covered without blocking airflow.
Room size and loading side still come first
Choose 12 kW for an adjusted 212–424 cu ft room or 18 kW for 318–636 cu ft. Add about 4 cu ft for every square foot of glass, tile, brick, concrete, or other uninsulated surface; multiply a massive-log room by 1.5. The firebox door stays inside the sauna, keeping the flame and tending ritual in the room.
What this package does not finish
- Chimney system and roof or wall pass-through components
- Floor and wall protection required by the exact installation
- Local solid-fuel approval and installer review
The current manual and 24-month limited warranty are in Manuals & Documents. Use them before the room is closed up.
