STOVEMAN 13R internal firebox

The STOVEMAN 13R sauna heater is designed for both dry and wet steam in the sauna. Thanks to the large amount of stones, Stoveman sauna stoves offer a pleasant sauna experience with a pleasantly soft, smooth and long-lasting steam.

"The Stoveman 13R sauna heater has improved air circulation, with 6 air ducts in the outer walls of the firebox! The air ducts receive the circulating air from the bottom of the stove, and as it heats up, the warm air moves up the ducts and exits between the upper stones of the stove. The STOVEMAN soffit is reinforced with stiffening elements such as corners and stiffening edges. The corners also act as cooling channels for the firebox, as cold air enters the openings from below and, as it moves upwards, it warms up and heats up the sauna room faster. In addition, some fireboxes are double-walled.

The external shape of the Stoveman 13R sauna heater grill is round (R).

Materials: 

• All parts of the sauna heater in contact with the flame are made of 5 mm thick steel sheet.
• The bottom of the sauna heater is made of 3 mm sheet steel.
• The ash box is made of 2 mm sheet steel.
• The handmade ash grate is made of 10×20 mm square steel.

For efficient heating, the base plate has ventilation openings in the sauna to allow air to enter the stone compartment. The base itself is made of rigid metal sheet and can withstand the heavy weight of the stones without deforming.

Stones are not included.
