A comment
I was looking for a storage water heater, with a volume of 50 liters, in the store I was advised to take the Garanterm ES Slim, which I did. At a cost, the model can be attributed to the economy class, since at the time of purchase the boiler cost me only 4000 rubles. Externally, the model looks good, the boiler is not bulky, the shape is round.
The inner tank is covered with reinforced enamel, so we are not afraid of the formation of corrosion in the water heater. The water heats up very quickly, there are no problems with this and, fortunately, cools down for a long time.
And if you think it is more profitable to buy a flow or storage water heater, then choose the last option. My electricity bills haven't changed much. But the parents have flowing, so he winds up a lot, constantly works, not at all economical.
I like my model!
