Brand: Havells
Hot and ambient dispensing at a sane price
Our editorial score
Very good — recommended
Buyers who want hot water on tap without paying premium-brand prices.
The Aqua S is the value play in hot-water purifiers. AO Smith's Z9 is the better machine, but it is ₹34,000 and the Aqua S delivers the feature that actually changes your daily routine — instant hot water for tea, coffee and baby formula — for ₹21,500, in a better-looking body, with a three-year membrane warranty attached.
Two things to plan for. The hot tank takes space from ambient storage, so effective cold capacity is modest. And at 300 W while heating this is a real appliance load — if you are in an area with load-shedding or a small inverter, that matters.
Every condition below is derived from this product's published specifications and from how it compares with the water purifiers we track — so you can check each one against your own room, supply or budget rather than take our word for it.
Your supply runs above 2,000 ppm TDS
The membrane is rated to 2,000 ppm. Feed it more and it will not fail dramatically — it will die early and quietly, and you will be buying membranes annually. Check your worst-season reading, not your average one.
Purifiers for high-TDS supply →Water wastage matters to you
The brand does not publish a recovery figure, so there is no way to know how many litres go to drain per litre purified. Only 2 of the 26 water purifiers we track publish this at all.
High-recovery purifiers →Weak transparency. This is separate from our review score above — it measures how well documented, how supportable and how expensive to own this water purifier is, scored on 6 of 7 axes by formula, with no manual override. See the methodology.

Specifications are from manufacturer literature and were checked at the last price-verification date. Brands occasionally revise stage counts, tank sizes and warranty terms without changing the model name — confirm against the current listing before purchasing.
A trusted electricals major whose purifiers punch above their weight on design and on genuinely useful engineering — Havells' revitaliser and corner-mount designs solve real kitchen problems. The Aqua S hot-and-ambient dispenser range is a standout.
