I was in need of a Geyser for warm water in my house, I have searched so many Geysers some were of high cost and some use more power one of my electrician friend has suggested me Cymptom Greaves 15L SWH 315 E Geyser and to my surpirse the Geyser was good enough.
The size of the Geyser is medium so that we can install inside the Bathroom without any problem. The Geyser has automatic thermostat means if water get heated the power automatically cutoff this saves electricity.
The water also get warm too fast it takes around 2mins to get water to warm up.
