Havells is a very well known brand and their products speak quality but i'm very very disappointed with the after sales installation process. Firstly, when the installation guy called he asked for next days appointment. When he came for installation he started cribbing about the trouble of having to uninstall the old heater and fix a new one. Then he mentioned that he would only fix the heater on the wall and won't do the electrical fitting. He also argued that it's not his job to let me know that the installation process does not include electrical fitting. I mean, I haven't bought the heater as a show piece. What sense does it make to just mount the heater on the wall and go away without even checking whether it's functioning properly or not. I had to tell him to leave immediately. Finally, i got the heater installed from the local electrician. If this is the kind of service at the time of installation i shudder to think what kind of after sales service would the company provide if at all there is some problem in the heater. Overall, a very bad experience as far as installation process is concerned.
Further update to my review. As I have been using the heater for a free months now, i would strongly recommend against buying this heater if you are staying in a region where temperature falls very low. This heater is gonna take forever to heat the water. I had to wait till eternity to get a decent hot water in Mumbai winter which is almost a shame in comparison to winters of Delhi. Don't buy this heater
This product is awesome. This product is very good for low winter and if we use this product in high winter this product need time and use high electricity. This product over all save electricity if we use this product for a small family this product is very good.
After installation of Water heater, it is not working properly. It will take much time for heating and once tape will open for usages it will immediately start cold water. Now, it is in not working condition. Request you to please send service engineering or I will go to customer forum and raise cases for reimbursement.
Most of the comments where people have mentioned that it cannot be used for shower must know that this cannot be used for shower. It is a simple 3L geyser which heats up water quickly and fill that water in a bucket. If you leave the geyser on and pun on the tap on a slow speed, you can easily get full bucket of hot water in 8-10 mins. If you need continuous hot water shower, you probably need a bigger and costlier geyser. For a small family, this geyser is the best solution .
It takes 2-3mins for heating water..For a bucket full hot water you will have to wait for 10 mins..But remember the water will be steaming hot..So we have to plan much before taking bath..Since, it is a 3l instant geyser, u can't expect more than that.. After every 3 mins, the blue light turns amber (auto cut off)..if u don't collect hot water immediately,the geyser stops working.. Initially we didn't understand what the problem could be..then got to know that the small red button at the bottom should be pressed (as we do in case of mixers) for bringing back the geyser into working condition.. Safety wise this geyser is the best..Only thing is that one should be aware of functioning of this geyser.. Overall a smart purchase..
