Narvi Sauna Stone Package is required to operate
Narvi Inari is an original looking sauna heater. This new product with a sturdy structure and grid also ensures long and enjoyable steam for frequent sauna users. Stones visible behind the grid make the heater very attractive. Thanks to the stone grid offered as an optional accessory, old Kota L and new Luosto sauna heaters can be turned in a representative Inari sauna heater.
The environmentally friendly sauna heater heats up with a relatively small amount of wood. The sauna heater has a glass door with a cast-iron frame and adjustable legs.
The flue can be attached on the top of the sauna heater. The user can make a hole in the stones basket for rear attachment of the flue. The hole can be made with a saw for iron, using it to cut through three steel wires in the basket.
Narvi Inari vs. Narvi Inari Plus – Key Differences
Both the Narvi Inari and Narvi Inari Plus are high-quality wood-burning sauna heaters designed for sauna rooms of 8–18 m³. They share the same dimensions, safety distances, and durable black steel casing. The main differences come down to heat capacity, performance, and feel.
Stone Capacity and Heat Performance
-
Narvi Inari: Holds 60 kg of stones, providing fast heat-up times and a more responsive sauna experience.
-
Narvi Inari Plus: Holds 90 kg of stones, offering a softer, more even heat and improved heat retention for longer sessions.
The larger stone capacity of the Inari Plus results in gentler steam and steadier warmth, making it ideal for those who prefer a more traditional, soft-steam sauna experience.
Weight and Structure
-
Inari: 54 kg
-
Inari Plus: 61 kg
The Inari Plus is slightly heavier due to its reinforced build and larger stone compartment, contributing to better heat storage and durability.
Dimensions and Installation
Both models share identical installation measurements and safety clearances, meaning they can be interchanged without adjustments to your sauna layout or flue connection.
