Water thrown on heater
We recommend using hand-warm water. The water used for throwing on the heater should be house-
hold fresh water. Smoother steam can be achieved by throwing the water to the heater sides / lower
stones. If you want tougher and more aggressive steams, pour plenty of hot water all at once on the
heater.
Sauna room structure
The sauna, and especially its roof, should have good thermal insulation, as the steam tends to escape
through the roof. Due to moisture we recommend using aluminium foil. The heater is dimensioned
according to the sauna space.
In addition to the conventional sauna structure (wool insulation, foil, timber), the power consumption
is also affected by the following; if the sauna has walls made of uninsulated stone, tile or concrete
surfaces or timber, the heater power should be slightly increased.
The heater power need (kW) increases for every uninsulated square meter the same amount as if
increasing space by 1.2 m
3
and on timber surfaces by 1.5 m
3
. Also the glass surfaces (glass walls,
doors and uninsulated stone surfaces) are calculated as 1.2 m
3
per square meter. Choose a higher-
powered heater in borderline cases.
The sauna needs to have an efficient ventilation in order to achieve a good oxygen level and get fresh
air. The air change rate needs to be at least 6 times per hour. For a sauna with an electric heater, the
most convenient ventilation is mechanical. We recommend to place the valved fresh air tube above the
heater (min 50 cm) either on the wall or in the roof. The exhaust valve should be placed as far away
from the heater and as close to the floor level as possible. An option is to lead the exhaust air below
the sauna door into the wash room. In that case there has to be a minimum 50 mm opening between
the door and the floor. It is highly recommendable to install an exhaust air valve in the roof, through
which moisture exits after the sauna session.
