I order a badtunna end of 2019 and had corrosion issue from the beginning. The stove has white spots growing, which are a result of the corrosion of the aluminium stove. It can be removes manually but leaves a hole in the metal. I am afraid that after some more years in use the metal will be totally perforated and the water will come through, making it useless.
I have followed all the instructions they gave me but we still have the same problem. From my experience it is a design issue, having both stainless steel and aluminium in the same bath of water create a battery effect and encourage corrosion.
I do not recommend their construction.

Hello Nicolas, as we discussed earlier this problem occurs beacuse you havent used the sacrifical anode properly,this type of oxidation will only be on the surface, the "hole" will wont go trougt the stove. As you mentioned the sacrifical anode was completly worn out and needed to be repalced, this makes the oxidation to start on the stove instead of on the anode. You need to contact us to get a new anode to stop the oxidation of the stove.
