Gen 1 Reviews

The water heaters sold by AOS Bath are of superb quality. You can tell just by the looks of it. Moreover the glass coating on their heating element & tank; 'Blue Diamond', helps reduces the amount of scale build-up over time.

I've bought their 30L 'ELJH-30' water heater back in July 2021. Even though the price can be seen as slightly higher than most other brands out there, I genuinely and truly believe it's money worth spending.

My previous heater was also an AO Smith, and it lasted more than 15 years. Just installed the new heater today. Messrs Kalam and Mahadi did a very professional job with the wiring and piping. I hope that this new heater will also last as long.

I wish to add that this brand is superb reliable and lasting. The current 72L is a vertical model which has been discontinued and replaced by horizontal model, has been in use for more than 30 years, and never failed me once. The job done by Kalam and Rana team was impeccable. I can tell that they are very experienced in what they do.

Everything was done to my satisfaction including a thorough cleaning of the bathroom before they left. AOS Bath is highly recommended.
