KASTOR WOOD BURNING SAUNA STOVES
We thank you for your confidence in Helo
r’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 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 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.
