Choose Your Heater

Make sure the stove you have chosen is right for your sauna. A sauna room equipped with a suitable stove will be ready for bathing after it has been heated for a half an hour to an hour.

The heating of the sauna room depends on the size of the room, power of the stove and materials used in the walls and ceiling of the room.

Greater capacity of the stove is required if the wall and ceiling surfaces are un-insulated (brick, tile or concrete for example). In this situation each square meter of un-insulated material needs to be calculated as a 1.2 cubic meter in addition to the cubage of the sauna. If the walls of the sauna are timber logs, the additional cubage needs to be the original cubage multiplied by 0.5.

For example, a 10m³ sauna room with a 2m wide and 2m high brick wall equals a 14.8m³ sauna room. (2×2=4m²; 4×1.2=4.8m³ in addition to the original 10 m³)

A 10m³ sauna room with walls made of logs equals to a 15m³ sauna room and the stove has to be chosen accordingly. (10 m³ x 0.5=5 m³ in addition to the original 10m³)
