We bought this heater on 28/06/19 after a month bad smelling water was coming out from it . We called the call centre they sent a technician they charged us 1350 rupees . Now again the same problem. The service is slow and poor and they keep on changing their technicians. Never buy this brand as its pathetic. You will regret heavily by buying this brand. Their technician said that if the geyser is not used for 15 days the smell will come because of the type of thermostat element and glass it has inside, it then has to be cleaned inside. So for people who travel frequently have to come back and wait for the technician to come to clean it every time. After that only you can have a bath .
