5 best Wi-Fi geysers in India: Smart water heaters you can control using your phone

A geyser is usually switched on a few minutes before someone needs hot water. During winters, that wait can feel particularly frustrating, especially on mornings when everyone in the house is getting ready around the same time. Wi-Fi-enabled water heaters attempt to solve this with remote controls, scheduling and temperature settings that can be managed through a smartphone.

However, not every smart geyser offers the same set of features. Some let you operate the appliance through Alexa and Google Assistant, while others go a step further with energy monitoring, dedicated heating modes and vacation settings. If you're considering one for your bathroom, here are five Wi-Fi geysers available in India that are worth looking at.

Haier ES15V-SD Wi-Fi

The Haier ES15V-SD is a 15-litre smart water heater with a 2,000W heating element and a 5-star BEE rating. It is listed with Wi-Fi and remote-control functionality, along with a smart timer and memory function. The latter can be useful if you prefer keeping your heating settings consistent instead of configuring them every time you use the geyser.

There is more to its specifications than connectivity. Haier lists an 8-bar working pressure rating, an IPX4-rated body, an Incoloy 800 stainless steel heating element and a corrosion-resistant UMC inner tank. It also gets a PUF insulation layer, a magnesium rod and protection against overheating and excessive pressure.

Its 15-litre capacity makes it worth considering for smaller households, although families with higher hot-water requirements should look at a larger variant.

Racold Omnis Slim Wi-Fi

Racold's Omnis Slim Wi-Fi takes a slightly different approach, combining connected controls with a focus on heating performance and tank durability. It uses a 2.5kW titanium heating element, which the company claims delivers heating performance equivalent to a 3kW output. The element also comes with a seven-year warranty.

The Racold NET app lets users switch the geyser on or off, adjust the temperature and schedule heating remotely. It also supports Alexa and Google Assistant, so users can operate the appliance through voice commands. The app additionally supports energy tracking, real-time alerts and an AI-ECO mode.

There are some useful hardware features here as well. The geyser gets a titanium-enamel-coated tank, auto-diagnosis functionality and a digital touch control panel. A three-second safety check indicator checks the appliance before use, while the company also lists a dedicated children-care mode to regulate water temperature.

V-Guard Pebble Shine Smart

The V-Guard Pebble Shine Smart is a 15-litre storage geyser that puts considerable emphasis on energy monitoring and smart-home integration. Its Wi-Fi-enabled digital controller allows remote operation, while compatibility with Amazon Alexa and Google Assistant means users can also control it through voice commands.

One feature that makes it stand out is the ability to monitor electricity consumption through the companion app. Users can also set energy limits, which provides a better idea of how much power the appliance is consuming. There is a child-lock function that prevents temperature adjustments through the physical control panel, which can be useful in households with children.

V-Guard has also equipped the geyser with a titanium-enriched vitreous enamel-coated inner tank, an Incoloy 800 heating element and a sacrificial magnesium anode rod. The company lists it as suitable for hard-water conditions and high-rise buildings, with a maximum operating pressure of 0.8MPa.

Havells Adonia i

Available in 15-litre and 25-litre capacities, the Havells Adonia i combines conventional water heating with connected features such as remote operation, scheduling and geofencing. These features allow users to manage the geyser through a smartphone instead of relying entirely on its physical controls.

Its companion app supports weekly scheduling and multi-user access, while Amazon Alexa and Google Assistant compatibility adds voice controls. The geofencing feature can also automate operation based on the user's location, making it useful for those who follow a fairly fixed daily routine.

On the hardware front, Havells has included a Feroglas-coated inner tank, a 2,000W Incoloy glass-coated heating element and an 8-bar pressure rating. The company offers seven years of warranty on the inner tank and four years on the heating element.

Venus Splash Pro IoT

Venus Splash Pro IoT is another option for buyers who want connected controls but don't want to compromise on features related to tank protection and maintenance. It is available in 15-litre and 25-litre variants, both using 2,000W heating elements.

Its smart features include remote operation, scheduling, temperature monitoring and multi-user app access. There is also a Vacation Mode that can be useful when the house is unoccupied for a few days. Another interesting addition is the Smart Mode, which maintains the water temperature at 45 degrees Celsius, according to the manufacturer.

The geyser also has an Antibacterial Mode that raises the water temperature to help inhibit bacterial growth. On the hardware front, Venus uses a porcelain enamel glass-lined tank, double-sided enamelling, a larger anode and glass-lined double ceramic heating elements with Scale Guard Technology. The 3cm-thick PUF insulation is intended to reduce heat loss and retain hot water for longer.

Venus claims a heating time of 20 minutes for the 15-litre model and 33 minutes for the 25-litre variant when raising the water temperature by 35 degrees Celsius. The geyser is rated for pressures up to 8 bar, making it suitable for compatible high-rise installations. The company lists a ten-year inner-tank warranty.

What should you check before buying a Wi-Fi geyser?

• Storage capacity: A 10- or 15-litre geyser may be sufficient for one or two people, but families with higher hot-water requirements should consider a 25-litre model. The number of people sharing a bathroom and the type of bathing routine also matter.
• App functionality: Don't assume every Wi-Fi geyser offers the same controls. Check whether the app supports remote switching, scheduling, temperature adjustment and energy monitoring. If you use Alexa or Google Assistant, verify compatibility with the exact model.
• BEE star rating: A higher star rating can indicate better energy efficiency under the applicable BEE testing conditions. However, compare the rating for the exact model and capacity rather than assuming that every variant in a product series has the same rating.
• Tank and heating element: Look at the inner-tank coating and heating element material, particularly if your home receives hard water. Scale formation can affect heating performance and increase maintenance requirements over time.
• Pressure rating and safety: If you live in a high-rise apartment, check the geyser's rated water pressure. Thermal cut-outs, thermostats and multifunction safety valves are also important when choosing an electric storage water heater.
• Warranty: Pay attention to the separate warranty periods for the product, heating element and inner tank. A long tank warranty does not necessarily mean that all components receive the same coverage.
