Accumulative water heater brand Oasis SV-50L, was purchased due to low cost (cost me only 2700). The boiler is overall, it is mounted vertically, the dimensions are as follows: diameter 38.5 cm, height 68.9 cm.
It heats up quickly enough, in the summer you have to wait about 45-50 minutes, and in the winter it takes 1.5-2 hours, the difference is due to the temperature of the water in the water supply. Heating occurs from the network, when you turn on the water heater, the red light immediately turns on, which informs about its operation. At the top of the tank you can see the temperature of the heated water at a given time.
50 liters is enough for 2 people, you can safely wash. So I think the purchase is useful, especially during a period when there is no hot water in the water supply. I’ll advise you, the unit does not fail me, the water heater is working properly and efficiently, it doesn’t bother me with the control.
pros
Volume, adjustment of the degree of heating, the water stays warm for a long time
Minuses
Heavy installation requires strength
