Thank you for having chosen our heat storing Aito sauna
heater. To make the most of your sauna heater please read
the manual carefully before you start installing and using it.
1.1 General information
Aito sauna heater is the traditional heat storing sauna
heater, which lets you enjoy steam in its truest form. The
stones are heated at once into a red glow, after which the

The sauna heater will be shipped in parts that are ready to
be installed. The parts will be assembled without plaster
onto the desired spot.
