I personally use this powerpye hot water geyser in my home. It is best at it service & durability. However, it takes time to convert cold wter into hot, as it is works through electricity.
Well, it is an electric geyser but consumes less units and is user friendly. 25 litres is sufficient for a smaall family but for a joint family it doesn't work. In my family, there are 4 members & we are okay with this geyser.
One of the most impressing thing is after sales services provided from fitting to fixing everything. Its working life is also good. I am using it for 5 consecutive years & having no problem in its working. So, will definitely suggest it.
