I took it for a distillery, a tank of 20 liters. In the open veranda at the dacha, the heating of the tank began, for the first hour everything was stable, but then it started, then error E6, reconnected the power, an hour later I come to the OFF display. I started the distillation again, left, I come again an hour later and again OFF. Slippery surface, no limiters are provided, the tank can move off the plate at the slightest vibration. The plate is unstable. I do not recommend buying for this price and with the above problems.
