COZY Quattro Wood Sauna Stove
The heart of sauna is the heater. If the heat is not mild and you feel uncomfortable, then usually the stove is the problem.
Wood- heated stoves are best for mild and long lasting heat, they are made for making the steam by throwing some water on the stones. We have been producing the sauna stones more than fifteen years and our specialists know all the secrets of good sauna already for generations
COZY Heat stoves are unique. They are the only producers that meet the German BIMSCH certificate requirements in TÜV test without supportive equipment’s. Stove needs at least 25% fuel compared to similar heaters. In the test it was needed even 40% less fuel.
Smoke gases are 6x cleaner compared to similar heaters.
The safety room between the heater and flammable material (wood) is only 9.1 in without any fire protection screens.

PLAN THE WHOLE SAUNA
The room and heater still have to work as one system.
Start with the room dimensions, then account for glass, masonry, insulation, ceiling height, required clearances, and available electrical service. That is how we move from a product that looks right to a sauna that heats evenly and comfortably.
