Hello. I’m going to share my personal experience about this vintage dip and heating device. Basically I have 2 water heaters at home. One is this one and another one is Bajaj which we recently bought. And we bought the bajaj heater for a reason. And the reason was, this water heater gives you an electric shock in the water! If you dip the heater in the water and touch it, you will feel the electric shock and this happens almost every time depending on how you have plugged the wire. If you get an electric shock, then you will have to reverse the polarity of the plug by rotating it and plugging it again and then there won’t be any shock. We could do this every time, but it is very dangerous when we’ve got small children at home who loves playing with water!
