Havells Carlo vs Instanio – What’s the same?

Type & Capacity

Havells Carlo and Instanio are instant heaters. Both take up very little wall space in your home to provide access to hot water without wasting a lot of time. They also have a 3-litre capacity to always keep the water in the heater stored and release it as soon as you open the tap.


These two instant water heaters don’t require a lot of energy as they can be powered from any standard wall outlet in your home to heat the water in a few minutes. Both Havells Geysers are available with a normal power consumption of 3000W, which can save electricity by heating a large amount at once, so you don’t have to waste energy on the heating elements every second.


Each water heater can be placed vertically in your bathroom and mounted on the wall near the outlet and water inlet to enjoy a constant flow of hot water all year round. Unfortunately, Havells doesn’t offer a free installation service for both units, so you’ll need to hire a plumber close to your home to make all the connections.

Auto Cut-Off & Indicator

Yes, you get an automatic cut-off feature on both devices, so even if you leave the Geyser on for hours on end, you shouldn’t have any overheating issues on the device. The temperature LED on both devices shows when the water is heated and ready to use. In addition, the stainless-steel tank helps keep the water warm for hours to save electricity in your home.


As the Havells water heater is made from Stainless steel material you get an impressive 5 years of tank warranty with both devices. Also, to make things even better for consumers there is an added two years of warranty on electrical components and body parts of the geyser. 

Havells Carlo vs Instanio – What’s so different?


Coming from the same brand, Havells Carlo and Instanio has completely different design. The first set is much more compact and ideal for households that don’t have a lot of bathroom space. The second geyser gives you a modern look that not only looks better than the others but also has a round LED that shows the user temperature.


While comparing the weight of Havells Carlo and Instanio, we found that Carlo water heater comes with less weight than the other. Havells Instanio is half a kilogram heavier which can make the installation process harder. The extra weight of Instanio is due to the bigger frame that takes more space on the wall of the bathroom.
