Selecting heater

  • If the walls or ceiling of your sauna contain non-insulated stone/glass or equivalent surface, the heater will require more power.
  • For each non-insulated square meter, 1.2 cubic meters are added to the volume of the sauna.
  • If the interior wall of the sauna room is non-insulated log, the corresponding factor is 1.5.
  • Remember that the walls and ceiling in particular need to be very well insulated.
  • You should also pay attention to sauna room ventilation.
  • Efficient air circulation ensures that the bathers can enjoy clean air that is easy to breathe.
