Orient Electric
Orient Electric Ultimo 50L Desert Air Cooler (CD5002H)
₹9,490

Havells
Havells Instanio 3L Instant Water Heater
₹4,290
A 3 litre instant heater suits a kitchen sink or washbasin, not a shower. It heats on demand so there are no standing losses, but the small capacity cannot sustain the flow rate a shower needs.
Full details →Who the Orient Electric Ultimo 50L Desert Air Cooler is for
Buy it if: Households in dry-climate regions such as Delhi, Rajasthan and central India, where evaporative cooling is effective and running cost matters.
Avoid it if: Anyone in a humid coastal city, where evaporative cooling adds moisture without meaningfully reducing perceived temperature.
Who the Havells Instanio 3L Instant Water Heater is for
Buy it if: Kitchen sinks and washbasins needing hot water on demand without a stored tank.
Avoid it if: Anyone needing hot water for showering, who should choose a 15 litre or larger storage heater.
