Smart Geyser Buying Guide: Smart geyser goes beyond the traditional model by offering features like temperature customisation, mobile-app or WiFi connectivity, scheduling hot-water, and monitoring energy usage. While the basic job remains heating water, the added “smart” features give enhanced convenience.
Set your budget and pick wisely
Smart models range broadly in price depending on brand and feature-set. Don’t simply go for the cheapest—look for a reliable tank, good insulation, trusted brand support, and essential safety features. If you’re paying extra for WiFi or app-control, ask yourself how much you’ll actually use them.
Choose the right capacity for your home
Size matters. Picking an oversized heater wastes energy; too small and you’ll run out of hot water just when you need it. As a rough guide:
-
6–10 litres for 1–2 people
-
15–25 litres for 3–4 people
-
25+ litres (or higher) for large families or homes with bathtub usage
For kitchens, a small-capacity instant heater of 1–3 litres might suffice.
Energy efficiency and operating costs
Energy efficiency impacts your electricity bills significantly (especially in winter). Look for models with good star-ratings from local regulatory bodies (e.g., minimum 4 stars). Also check the wattage: higher wattage may heat faster but costs more to run. Smart standby features (like automatic cutoff) help reduce wasted energy.
Installation and placement matter
Correct placement ensures both safety and performance. Consider whether you need a vertical or horizontal model depending on wall space and ceiling height. Ensure the wall can bear the weight, ventilation is sufficient, and the outlet is nearby to minimise heat loss. Professional installation is strongly advised for safety and warranty validity.
Consider water quality and durability
If your water is hard (high mineral content), it can shorten the lifespan of the heater. Look for corrosion-resistant materials such as glass-lined tanks or ceramic elements. Descaling at least once a year helps maintain performance and avoid internal damage.
Safety features you shouldn’t ignore
Especially in homes with children or elderly residents: thermal cut-outs, pressure‐release valves, anti‐corrosive bodies, child locks on digital models, and alerts for leaks or malfunctions are all valuable. Smart geysers may also allow you to regulate maximum temperature to avoid scalding.
Brand reputation and after-sales support
Select a brand that offers a strong warranty (for both tank and heating element separately), reliable service centres, and clarity on installation cost (some brands offer free installation). Ask about spare-parts availability and check reviews for real-world service experiences.
Final checklist before you buy
-
Confirm your required capacity.
-
Match capacity with your daily usage pattern (showers, baths, kitchen use).
-
Check energy rating and find models with low standby consumption.
-
Verify installation feasibility in your space (vertical/horizontal, outlet distance).
-
Ensure water‐quality compatibility or plan for softening if needed.
-
Review safety certification and included features.
-
Research brand service network and real user feedback.
-
Compare cost vs features: WiFi/app control is useful, but only if you’ll use it.
