KASTOR WOOD BURNING SAUNA STOVES
We thank you for your confidence in Kastor’s products. We have manufactured wood burning
sauna stoves for nearly a century now, longer than any other company in the world. Over these
years, we have learned a lot about fire, its handling and its precariousness. Anyone can light a
fire, but nurturing it is nearly a form of art. We have two guidelines in design and manufacturing:
A master’s touch leaves nothing extraneous and a master’s touch cannot be achieved with low
grade material. Our products are simple and reliable, although their elegant form is based on
solutions born from decades of experience and the latest technology.
QUALITY MATERIAL
Our products contain only the best possible material, procured from reliable suppliers we have
gathered over the years. The steel is Finnish structural steel from Ruukki, which can be bent into
various solutions while retaining its hardness due to its uniform quality. Our glass covers are
Ceram glass, which can withstand up to 800 °C (1472 °F) while still allowing the fire’s warm glow
to spread into the room.
WE KNOW FIRE
Our products are heavy, which by itself is a sign of fireproof construction. Still, it is not the steel’s
thickness but its correct use that is important. One needs to know how fire behaves. The hottest
and most stressed part is not necessarily directly above the fire, depending on how the heat is
being channelled. The fire must also be supplied with air to ensure optimally clean burning and
economical heating.
SUPERIOR TECHNOLOGY
Our stoves can be fully heated with just one load of wood and they retain warmth long after the
flame has died down. This unique property is the sum of many factors: High quality material, the
Coanda- air circulation system, the air guidance sheet, the large and deep stone compartments
and the sturdy doors. Read more about these and our other technical innovations as well as our
comprehensive installation supplies at www.kastor.fi or in our prospectus.
