1.1. Piling of the Sauna Stones

The piling of the sauna stones has a great effect on
the functioning of the heater (figure 1).
Important information on sauna stones:
The stones should be 5–10 cm in diameter.
•
Use solely angular split-face sauna stones that
•
are intended for use in a heater. Peridotite,
olivine-dolerite and olivine are suitable stone
types.
Neither light, porous ceramic "stones" nor soft
•
soapstones should be used in the heater. They
do not absorb enough heat when warmed up.
This can result in damage in heating elements.
Wash off dust from the stones before piling
•
them into the heater.
Please note when placing the stones:
Do not drop stones into the heater.
•
Do not wedge stones between the heating
•
elements.
Place the stones sparsely to ensure that air can
•
circulate between them.
Pile the stones so that they support each other
•
instead of lying their weight on the heating
elements.
Do not form a high pile of stones on top of the
•
heater.
No such objects or devices should be placed
•
inside the heater stone space or near the heater
that could change the amount or direction of
the air flowing through the heater.

1.1.1. Maintenance

Due to large variation in temperature, the sauna
stones disintegrate in use. Rearrange the stones at
least once a year or even more often if the sauna
is in frequent use. At the same time, remove any
pieces of stones from the bottom of the heater and
replace any disintegrated stones with new ones. By
doing this, the heating capability of the heater stays
optimal and the risk of overheating is avoided.

room, it will take about an hour for a properly
insulated sauna to reach the required bathing tem-

unit model.

1.4. Throwing Water on Heated Stones

The air in the sauna room becomes dry when
warmed up. Therefore, it is necessary to throw
water on the heated stones to reach a suitable
level of humidity in the sauna. The effect of heat
and steam on people varies – by experimenting,
you can find the levels of temperature and humidity
that suit you best.
