Smart Geyser buying guide: What to check before buying, right capacity for your needs and other tips

Winter is coming. Now, that will require installing geysers in homes in most parts of the country. These water-heating devices are needed in bathrooms and kitchens, so selecting an appropriate model requires considering safety, efficiency, and connectivity factors. In today’s connected homes, smart geysers are quickly becoming a convenient and efficient choice for managing hot water needs. Whether it’s controlling temperature through your smartphone or saving energy with automated settings, smart geysers bring both comfort and efficiency to daily routines.

The market offers several smart geysers with features such as Wi-Fi connectivity, mobile app controls, and temperature customisation. However, factors such as capacity requirements, energy efficiency, installation needs, and warranty details remain essential when purchasing a new smart water heater.

We have compiled a detailed guide covering things to keep in mind before buying a smart water heater for your home. Here’s how to select the right model, understand key features and ensure proper installation for your home.


What is a smart geyser and how it works

Let’s start with understanding what a smart geyser is and how it works. Traditional water geysers heat water using a heating element. Meanwhile, smart water geysers offer additional features, including temperature regulation and mobile app control. These features allow users to schedule heating, customise temperature settings, monitor energy consumption, and set preset timers.


Set your budget and shortlist accordingly

Smart water heater prices in India can vary by model and brand. Avoid buying the cheapest option. Instead, choose a quality model with durable tanks, energy efficiency, safety features, and a reliable brand. Consider which smart features you actually need. Some models offer Wi-Fi control and app connectivity, which increases the price.


Smart features and controls

Smart water heaters offer mobile app connectivity, allowing users to schedule water heating, customise temperature settings by bath mode, check daily energy consumption and set preset timers. Temperature control is a key feature, with some models offering various settings and digital displays on the geyser that show the current water temperature. These features provide convenience but are not critical for basic water heating needs.


Choose the right capacity for your household


Tank size affects how much water it can store, heating time, and power consumption. Choose a water heater capacity based on your household size and needs. For example: A tank capacity of 6–10 litres for 1–2 people, 15–25 litres for 3–4 people, and 25+ litres for larger families or homes with bathtubs is ideal. Meanwhile, a 1–3 litre instant heater is suitable for kitchen use. The right size ensures comfort while saving energy and reducing electricity bills.


Consider energy efficiency to save on electricity bills


Energy efficiency impacts electricity bills, particularly during winter. Look for models with a high BEE star rating for greater savings. A rating of at least four stars helps save energy in the long run. Keep wattage in mind, as higher wattage heats water faster but can increase power usage. Select heaters with sound insulation to retain heat longer. Some smart geysers include standby cutoff features that consume less than 1 watt of energy even when left on for long hours daily.


Installation requirements and placement

Proper placement of the water heater is essential for safety and performance. Use vertical models for high ceilings and horizontal ones for low or small spaces. Ensure a strong wall and good ventilation. Keep the heater near the outlet to reduce heat loss and improve efficiency. Professional installation is advisable to ensure safety and compliance with local regulations, and it extends the lifespan of your geyser.


Water quality considerations


Hard water can lead to scaling and damage your water heater over time. To protect your investment, opt for models with glass-lined tanks or ceramic-coated elements and consider installing a water softener. Regular descaling at least once a year is necessary to maintain performance and extend the heater's lifespan.


Safety features to look for


Investing in a water heater with safety features provides peace of mind, especially for homes with children or elderly residents. Essential features include thermal cut-out, pressure release valves, anti-corrosive materials, and child locks in digital models. Smart geysers can regulate temperature to prevent water from overheating. Some models are equipped with alert systems that notify users about leaks or malfunctions.


Brand and warranty support


Select a water heater from a reputable brand that offers reliable after-sales service and a multi-year warranty. Confirm whether the company provides free installation or if it involves an extra cost. Review warranty terms carefully, as some brands offer separate warranties for the heating element and the tank. Ensure service centres and spare parts are easily accessible to support maintenance and dependable performance.
