One specific and rarely seen curiosity is use of a wood pellet burner to heat a smoke sauna stove, typically the actual burner installed into a room adjacent to the actual sauna room and the kiuas. A wood pellet burner, quite similar to an oil burner, is then used to heat a smoke sauna stove - practically a big pile of rocks. As the burning process is much cleaner than with a conventional smoke stove the smoke aroma is much less pungent and soothy, while the moisture produced by the burning the pellets makes the air more pleasant than with continuously warmed stoves.
