Frequently asked questions

Yes, it is. Just make sure the stones are hot before pouring water on them.

There are several different stone types. We recommend olivine diabase or vulcanite stones. Small stones 5-10cm are good for electrical saun aheaters, and the 10-15cm stones are good for wood-burning sauna stoves.

It really depends on the usage. If sauna is used 1-2 times per week, it would be good to change them once a year. Try picking up two stones and knock them on each other; if they crack, they should definitely be replaced.

The connection of an electrical sauna heater must be done by an qualified electrician.

According standard 60364-7-703 (Electrical installations of buildings) part 703.412.5, the sauna heater shall not be connected via residual current protective device (RCDs). Only a certified electrician is allowed to connect your electrical sauna heater.

THermostath should be place in the hottest part of the room. Our instructions say it should be 10cm down from the ceiling, above the heater.

Controller shows the temperature of the area where the thermostat is place. It is most likely hotter above the heater than in the other parts of the sauna. For safety reasons, the thermostat must monitor the hottest part of the sauna.

Any dry wood. We recommend birch, but any cleand and dry wood will do. Do not burn trash in the sauna stove.
