Hi, I just moved to a rented apartment which has sauna. However, the sauna is not hot enough, staying at around 50C only.

It is low temparature that the rocks still have water during sauna.

In what terms can I discuss this with the landlord? What if I contact and they do not want to fix it? I just sign a 1 year lease with them and cant really move out.

Thank you everyone for the comments! Here is the setup I used last night. Did I set everything correctly?

  1. Turn the thermostat higher or if you done that and it still doesnt heat you should contact them right away otherwise they might take the cost from you thinking you broke it.

  3. First we should rule out user error. Can you take a picture of the control panel.

    Have you definitely switched it on properly and are all of your breakers turned on or have any of them popped – there should be 3.

  4. How’s the ventilation when heating the sauna? In my apartment the central ventilation is controlled from the kitchen and if it’s on the max when heating the sauna it’ll suck the newly heated air out, capping the temperature to around 50C.

  5. Check that the sauna is properly on – some thermostat/timer knobs have a “warm up” period, eg: if you turn the knob to 4 hours, it’ll spend 2 hours being “warm” and 2 hours at proper sauna temperatures.

    Or, the thermostat itself could be broken. Beyond that, it could be the heating elements, electrical connection, eg: most electric saunas use 3 phase and one (or even two) wires could be loose (dangerous situation).

  6. I am assuming it is an electrical one. The communal one in my apartment building takes time to heat up, so on my appointments I am the first to be there for the day so I have to wait for the sauna to heat up. How long have you waited for it to heat up? If it doesn’t go over 50 C then definitely tell your landlord.

  7. Ok im pretty sure you have blown fuses. The stove has 3 fuse sets and 1 or two are blown, so check the fusebox first and if they are intact / blown, then i would say the stove itself is broken.. or the thermostat is set too low but i would assume anyone with this problem had checked this as its quite obvious one.. 🙂

  9. I don’t understand those controls. Timer is easy, but what are the other two supposed to be? Rajoittimen palautus and lämmitys?

  11. I think one or even two of the few (usually three in this size?) heating elements is gone. Fixing it costs more than a new stove. And installing the stove costs about the same as the stove itself. Totals to some 300 euros with a cheap model I think. But you’d need to contact your landlord for this…

  12. The stove probably has three heating coils, each on a separate fuse or breaker. Make sure each coil actually gets warm. We had this problem when we moved into our current apartment, and couldn’t get the sauna to heat up properly because two of the three fuses were blown.

  13. Take all the rocks out, turn the sauna on and see if all resistors start glowing after a couple of minutes. If they’re not then it’s an electronics fault. Also would be good idea to check the rocks and also clean up any dust while you’re at it.

    If all the resistors are fine and rocks are in good condition then it’s an issue with the thermostat.
