We bought a Vaillant AtmoMAG exclusiv 14-0 GRX geyser, because it could be built into a wall cabinet in the kitchen. This model assumes this arrangement for security.
But, unfortunately, the quality of the speaker was not good. Only in the first year of operation they were handed over 2 times to the service department for repair due to generator breakdown. As a result, repair work took more than 9,000 rubles for the whole time, although the cost of the column itself is not small. We bought it for about 15,000 rubles.
It became clogged a year later, the pressure became very weak, a tiny stream. I had to call the master and clean, it costs money again.
4 years after installation, the servo drive broke down, the price of this part costs at least 4000 rubles, plus you need to pay the master for the work. So this is not a column, but a money extortion machine. Do not buy.
Minuses
so many breakdowns, it's hard to remember
