A comment
I bought a Timberk SWH FS5 50 V water heater for a trivial reason - it was the cheapest in the amount of 50 liters (10,000 rubles). At the bottom of the tank is a small liquid crystal display, on which there are 4 control buttons. The temperature of water heating cannot exceed 75 C. The control is simple, you can figure it out without reading the instructions, everything is accessible and understandable.
In the tank, the water heats up quickly, but just as quickly it cools down, so you have to use it almost constantly. Water was not enough for 2 adults, not enough to wash normally. So if you decide to buy a water heater, take it better immediately at 100 liters, this option is suitable only for 1 person.
The tank is made of stainless steel, it looks good.The boiler works without unnecessary noise, it is not heard at all and it pleases.
pros
quickly warms, silent, stainless steel
Minuses
small volume lagging hours
