With winter setting in, I thought it was the perfect time to upgrade our old water heater. I had enough of those lukewarm showers during peak winter last year with our old gas geyser, so this time around, I wanted a reliable water heater that would keep me warm without the wait. While browsing through the Great Indian Festival sale on Amazon, I came across some great models, did a bit of research, and finally decided on one. Here’s a rundown of what I learned about picking a water heater, along with a few of my top picks if you are looking to get one yourself.
Key Things to Consider When Buying a Water Heater
Tank Capacity: Depending on your family size and usage, tank capacity is crucial. For one or two people, a 10-15 liter heater is usually fine, but families should look at 25 liters or more, so there’s enough hot water in one go.
Type of Water Heater: There are two main types: instant and storage water heaters. Instant heaters give you quick, on-demand hot water but aren’t ideal for long showers. Storage water heaters take a few minutes to heat up but provide a steady supply, perfect for families.
Power Consumption: Water heaters can impact your electricity bill, especially in winter. Look for models that are energy-efficient and come with a BEE star rating; a 4- or 5-star rated heater is best for reducing electricity usage.
Heating Element and Durability: The quality of the heating element affects how long your water heater will last. Glass-coated elements are more durable as they resist corrosion. Look out for stainless steel or copper tanks with corrosion-resistant coatings; they’ll last longer even with hard water use.
Safety Features: Safety is essential, especially with electrical appliances and water. Many good models come with auto shut-off, temperature control, and safety valves to manage pressure. This is worth double-checking, especially for storage water heaters that handle larger volumes of hot water.
My Top Picks for Water Heaters
AO Smith HSE-VAS-X-015 Storage Water Heater: This is the one I ended up getting in the Great Indian Festival sale, and it’s been working really well so far. AO Smith has a reputation for quality, and this model has a glass-coated heating element, which keeps it running efficiently. The 15-liter capacity is perfect for a small family, and it heats up quickly. It’s got a good energy rating too, which was important to me since I didn’t want any shocking electricity bills this winter. Plus, the warranty was pretty generous, which gave me peace of mind.
Havells Monza EC 5S 25-Litre Storage Water Heater: I checked this one out because Havells is quite popular for appliances in India, and I liked what I saw. The Monza EC 5S has a 25-liter tank, so it’s well-suited for families that need a lot of hot water at once. I visited a Havells showroom near home and tried it. It heats up impressively fast for a large-capacity heater. It also has a durable inner tank with glass lining to prevent corrosion. The outer body is rust-proof, which is ideal for areas with high moisture levels.
Crompton Amica ASWH-2015 Storage Water Heater: The Crompton Amica is a great budget-friendly option if you are looking for something reliable without spending too much. It comes in a 15-liter variant, which is a good size for small families. I noticed it had safety features like a temperature control knob and an auto cut-off, which makes it a safe option. The energy efficiency is decent, so it won’t drain your wallet with electricity bills. It also heats up pretty quickly, which is convenient when you’re in a hurry in the morning.
Bajaj New Shakti Neo 25-Litre Storage Water Heater: This Bajaj model caught my eye because it is another high-capacity model at 25 liters, so it’s perfect for larger households. Bajaj is known for making sturdy, dependable appliances, and this one has a decent build quality with a durable heating element. It’s designed to handle hard water, which is a big plus if you live in an area with hard water issues. It also has safety features like a pressure release valve and multiple protection layers, which is reassuring for families.
Racold Eterno Pro 15-Litre Storage Water Heater: Racold has a strong presence in the Indian market for water heaters, and the Eterno Pro is a solid mid-range option. I tried this at a relative’s place, and it was impressive in terms of both speed and efficiency. The 15-liter capacity is a good choice if you don’t need a huge tank. It has titanium-coated inner tank lining, which helps prevent corrosion, especially in hard water areas. I found the design pretty sleek and compact, which is great if you don’t have a lot of wall space.
Final Thoughts
I am happy with my choice of the AO Smith HSE-VAS-X-015; it’s been efficient, quick, and hasn’t hit my electricity bill too hard. If you’re looking for a small family model, I would definitely recommend checking it out.

This was such a helpful post! I’m trying to choose between the Havells Monza EC 5S and the Bajaj New Shakti Neo both seem like great options for a family of four. In your experience, how do they compare when it comes to heating speed and overall durability?
Thanks! Both are solid choices for a family of four. If heating speed is a priority, I would lean toward the Havells Monza EC 5S it heats up faster even with the larger 25-liter tank. Plus, the rust-proof outer body makes it pretty durable. The Bajaj New Shakti Neo is great if you deal with hard water since it’s designed specifically to handle that. So, if your area has hard water issues, Bajaj might have a slight edge in terms of long-term durability.
I have a small family of three and space is a bit tight in our bathroom I am torn between getting a 15liter or 25liter water heater How do you decide on the right capacity without wasting space or ending up with insufficient hot water? how reliable are these smaller models in terms of heating speed?
For a family of three, a 15-liter heater often suffices if your showers are staggered meaning not everyone showers one after another immediately. They heat up quicker and take less space, which sounds like it fits your bathroom situation perfectly. But if your usage is back-to-back or you prefer longer showers, a 25-liter model provides a more continuous supply without waiting for reheating. Smaller models like the AO Smith or Racold Eterno Pro are pretty reliable and heat water quickly enough for everyday use. In my experience, choosing capacity also depends on your daily routine if you can space out shower times, go with 15 liters; if not, better to invest in 25 liters to avoid running out mid-shower.
I live in an area with very hard water, and last winter my old geyser gave up because of corrosion issues. From your list, which water heater would you say handles hard water best without needing frequent maintenance? do you think investing in a water softener is necessary, or can I rely on these models alone?
Hard water can definitely take a toll on water heaters. From my experience, the Bajaj New Shakti Neo stands out because it’s specifically designed to handle hard water with corrosion-resistant elements and multiple protection layers. Racold’s titanium-coated inner tank on the Eterno Pro is also quite effective against scaling and rust. However, no water heater is completely immune to hard water damage over long periods. If your water hardness is very high, investing in a basic water softener or at least a good pre-filter can extend the life of your heater significantly and reduce maintenance. So ideally, combine a hard water-resistant model with some form of water treatment for best results.
I live in a joint family and use a lot of hot water for washing and bathing. Should I invest in multiple smaller heaters or one big 25-liter/30-liter model? How does it affect energy efficiency and installation?
For a joint family, a single larger-capacity storage heater is usually more practical than multiple smaller units. A 25-30 litre model like the Bajaj New Shakti Neo or Havells Monza EC 5S can cover multiple showers or washing needs consecutively. Using multiple smaller heaters can be cumbersome in terms of installation, space, and electricity wiring. Larger models are designed to heat and maintain temperature efficiently, especially if they’re BEE-rated. The key is to match the heater capacity to your household’s peak usage investing in one high-capacity, corrosion-resistant model is generally more efficient and convenient.
I’ve always worried about maintenance when it comes to geysers. Are glass-coated or titanium-coated tanks really much better for long-term durability compared to standard stainless steel? I’m looking for something low-maintenance.
Yes, Kamal, coating really makes a difference. Glass-coated and titanium-coated tanks resist corrosion and scaling far better than plain stainless steel, especially if you live in an area with hard water. The coating acts as a barrier, protecting the heating element and inner tank, which reduces frequent maintenance and extends the life of the heater. For low-maintenance use, models like AO Smith (glass-coated) and Racold Eterno Pro (titanium-coated) are excellent choices. Pairing these with periodic flushing and a basic water filter will keep your geyser in top condition for years.
I mostly take long showers and have a family of four. Instant heaters seem tempting for on-demand hot water, but do they really work for multiple consecutive showers, or should I stick with storage heaters?
For long showers and multiple users, Amit, I have always found storage heaters to be the more reliable option. Instant heaters are convenient because they give hot water on demand, but they tend to struggle when several people bathe one after another. The pressure sometimes drops, and they usually need a higher electricity load to maintain consistent output. With storage heaters, you avoid those mid-shower temperature dips because the water is heated in advance and kept ready. Models like the Havells Monza EC 5S or the Bajaj New Shakti Neo comfortably handle 3–4 back-to-back showers without the temperature fluctuating. Another thing I appreciate is that modern storage heaters have become far more energy-efficient. The newer 4- and 5-star rated units maintain temperature intelligently and do not consume as much electricity as older models used to.
I have a small bathroom and worry about space. Are there any compact 15-liter models that still heat water fast and don’t compromise on features like safety valves or energy efficiency?
Compact 15-liter models like the AO Smith HSE-VAS-X-015 or Racold Eterno Pro are designed for small spaces without compromising on essential features. They heat water quickly due to the smaller volume, and modern units include safety valves, thermal cut-off, and good energy ratings. The wall-mounted design keeps your bathroom uncluttered, and despite being compact, they’re robust enough for daily use. If you prioritize space but still want efficiency and safety, these models are the sweet spot. Make sure to check installation clearances and ensure the wall can support the weight once filled.
I’m considering a water heater for my 2BHK apartment, but electricity bills are a concern. Are the smaller 15-liter models significantly more energy-efficient than 25-liter ones? I don’t need a huge tank but want enough hot water for two people without a spike in power usage.
Generally, smaller 15-liter water heaters consume less electricity per use because they heat a smaller volume of water. They also recover faster, so if your showers are spaced out, they’re quite efficient. A 25-liter model naturally uses more power to heat a larger tank, but if you have multiple users in quick succession, it can save time and avoid waiting. Choosing a 15-liter heater like AO Smith HSE-VAS-X-015 or Racold Eterno Pro will likely suit your needs for two people while keeping electricity usage reasonable. For extra efficiency, look for 4- or 5-star BEE-rated models and ensure the bathroom is insulated to retain heat.
TBf, worried about temperature consistency. Some geysers take a long time to heat water, and others heat unevenly. Which of the models you mentioned gives the most consistent hot water temperature throughout a shower?
Trisha, for consistent temperature, storage heaters with good insulation and quality thermostats perform best. Models like Havells Monza EC 5S and AO Smith HSE-VAS-X-015 maintain water temperature uniformly throughout the tank. The inner coating (glass or titanium) helps in even heating and reduces heat loss. Quick recovery time and properly calibrated thermostats ensure your shower remains comfortably hot from start to finish. Instant heaters can fluctuate with water pressure or multiple users, so for consistency during long showers, a well-insulated storage heater is your best bet.
I have hard water in my area. Even the best heaters seem prone to scaling and corrosion. Besides buying a corrosion-resistant model, how often should I do maintenance to prolong the heater’s life?
Hard water is tough on water heaters, and you are right that even good models need some care to stay reliable long term. Corrosion-resistant tanks definitely help, but maintenance is what really determines how long the heater performs efficiently. Flushing the tank once every six to twelve months is one of the most effective habits. It clears out sediment and mineral deposits that settle at the bottom and slowly reduce heating efficiency while stressing the tank lining. If your heater uses an anode rod, checking it once a year is important because it acts as a sacrificial component that protects the inner tank from corrosion. Once it wears out, corrosion accelerates quickly. A simple inlet pre-filter or basic water softener can also make a noticeable difference in hard water areas by reducing scale buildup from day one. None of this needs to be frequent or expensive, but doing it consistently can easily add years to a heater’s lifespan and keep performance steady.
