Woodburning stove Harvia Classic 400 Top Duo

Harvia Classic Top stove takes sauna-bathers back 60 years to the time when the first woodburning Harvia stove was manufactured. Like the first Harvia stove, the Classic Top also has a cover. You can heat the Classic 400 Top Duo model easily from another room and enjoy a pleasant fire while heating the sauna. The outer casing of the stove combines stainless steel with  thick, painted graphite black iron. The large stone surface area of the stove provides a festive sauna bath experience. Through the cast-iron glass door the warm glow of the fire adds to the sauna atmosphere. The adjustable legs make the stove easy to place in the sauna.


The size of the sauna room is 494-1271 cu. ft. (14–36 m3) and the maximum amount of stones is 176 lbs (80 kg).


Read and follow at all times the Instructions for installation and use.
