This is about a water heater,
I purchased one 2 years back and that works well too, but the one I picked up for my house called shivalik 25 litres, I got a really very helpful experience when I purchased this water heater compared to many brands I found this water heater the best as it has a copper tank non corrosive tank and a copper coil takes very less time to heat, I calculated the total time taken to heat and found it heats water in 22 minutes which was very hot
