COZY HEAT HAS EMERGED FROM CRAFT THAT has been PERFECTED FOR GENERATIONS
Generations of tradition and knowledge in one modern sauna heater.
In 1967, in a small Estonian village, a young boy, future founder of COZY Heat, sat on a sauna bench while his father, Paul, tended the stove. Paul was a potter and a lifelong sauna man who believed that anything made by hand should outlast the person who made it.
Years later, that same boy stood beside his father, helping to build sauna stoves and learning that a good sauna is never only about heat but also the smoothness of the steam and the feeling of coming home.
We carry that memory forward in every heater we make: honest craft, lasting warmth and rich, gentle steam.
Longer steam, cleaner burning, less wood
Three main values that make our sauna heaters special.
01
Rich and Gentle Steam
COZY heaters are designed to create the kind of steam people remember: full, gentle and easy to enjoy. A generous volume of heated stones stores energy instead of releasing it all at once, keeping the sauna comfortable through a longer session. It is heat with depth, not sharp, short-lived bursts from an overheated metal stove. For long, unhurried time together.
02
More Heat From Less Wood
Our heaters are BImSchV certificated. COZY gets more from every log. Its efficient combustion and secondary airflow support a longer burn, lower flue-gas temperatures and markedly lower particulate emissions. Depending on the model, this can reduce firewood use by 25–40%, while cleaner smoke helps keep the chimney cleaner. Less wood, less waste and less time spent tending the fire.
03
Built for Years of Use
A sauna heater is not a seasonal accessory. COZY is made from 5 mm structural steel, manufactured under close quality control and backed by a five-year warranty. Certified to demanding European standards, it is built for the repeated heating cycles, hard use and long service life that a real wood-burning sauna heater must withstand, year after year, season after season.
Built to perform. Designed to impress.
Exeptional performance meets aestethic appeal.
With five distinct exterior designs to choose from, there is a perfect COZY stove for every sauna enthusiast.
Each model offers a unique visual experience. You can easily change the look of the stove by swapping out the stones. Sharp-edged stones add character while round stones bring elegance and softness.
It is also possible to get a new design cage that holds the stones to refresh the look and feel of your sauna, keeping it as dynamic as you are.
