Buying a Water Heater for the First Time? Here’s Everything You Need to Know
Buying a water heater for the first time can be confusing, especially with so many types, sizes, and features available in the Indian market. Whether you’re moving into a new home or upgrading your bathroom setup, choosing the right one from a wide range of water heaters ensures comfort and safety. Let’s explore some frequently asked questions (FAQs) to help first-time buyers make the right choice.
1. What are the main types of water heaters available in India?
In India, you’ll mainly find three types of water heaters:
- Storage Water Heaters:
These come with an insulated tank that stores hot water for later use. Ideal for families or areas with frequent power cuts, they’re available in capacities ranging from 6 to 25 litres. - Instant (Tankless) Water Heaters:
Perfect for small families or kitchens, they heat water instantly and are compact in size. However, they’re better suited for low-flow needs like washing utensils or taking a quick shower. - Solar Water Heaters:
Common in independent houses or areas with good sunlight, these use solar panels to heat water, significantly reducing electricity bills. - Gas Water Heaters:
Powered by LPG or PNG, they provide instant heating but require proper ventilation. Many Indian households still prefer electric models for safety and convenience.
2. How do I decide the right capacity for my home?
The ideal capacity depends on the number of users and the purpose.
Here’s a quick guide:
| Usage | Family Size | Recommended Capacity |
| Kitchen or small washbasin | 1–2 members | 1–3 litres (instant) |
| Single bathroom | 2–3 members | 6–10 litres |
| Multiple bathrooms | 4–6 members | 15–25 litres |
| Bathtub usage | Large families | 25 litres or more |
If you live in colder regions like Himachal, Uttarakhand, or North India during winter, go for a slightly higher capacity, as the inlet water temperature is lower.
3. What energy rating should I look for?
In India, the BEE (Bureau of Energy Efficiency) provides star ratings for appliances.
- Higher the stars, higher the efficiency. A 5-star rated water heater can help you save up to 20% on electricity bills annually compared to a 2-star model.
- Look for models with PUF insulation, which minimises heat loss and keeps water hot for longer durations.
4. Which is better? Vertical or horizontal water heater?
- Vertical water heaters are most common in Indian bathrooms, especially where ceiling height is adequate.
- Horizontal heaters are ideal for low-ceiling bathrooms or false ceilings, often found in modern apartments.
Both work well, but installation space and water pressure should guide your choice.
5. What about maintenance and warranty?
- Flush and clean the tank every 6–12 months to remove sediment build-up, especially in areas with hard water.
- Choose models with a glass-lined tank and magnesium anode rod for corrosion resistance.
- Most brands in India offer 2–5 years warranty on the tank and 2 years on the heating element.
Conclusion
For Indian households, the ideal water heater balances energy efficiency, capacity, safety features, and cost-effectiveness. Before buying, always assess your family’s usage pattern, local climate, and electricity costs. Investing in an efficient water heater pays off with lower energy bills and dependable performance for years to come.
