I am using this product for last 2 years. It is very good water heater. I brought this water heater in 2015 at price of 8999. Basically it have three option of heating normal medium and high it take 10 min to heatup water and yet not find any cons. It take just 5 min when you set heater at High option and what will be in boiling condition in 15 min.
But it some time make sound when you set option to high level. Otherwise this is best water heater with come 7 years Warrenty. For installation you need to call plumber Basically they don’t provide you installation.
You can get the product in different colour changing panel which looks awesome
