In summary

 
 

Choosing the right water heater involves matching capacity to family size, checking water pressure compatibility for high-rise buildings, and selecting 5-star energy-efficient models. Storage geysers suit multi-person bathing, while instant geysers work best for kitchen sinks and fast handwashing.

  • Water heater prices range from Rs. 3,500 for compact instant units to Rs. 25,000 for high-capacity digital geysers.
  • Instant geysers (3L to 6L capacity, 3,000W) provide immediate hot water for kitchen sinks and single users.
  • Storage geysers (10L to 25L+ capacity, 2,000W) hold heated water for batch family showers.
  • High-rise apartments require geysers with pressure ratings of at least 8 bar to withstand pressure pumps.
  • Glass-lined coated heating elements and sacrificial anode rods protect tanks against hard water corrosion.

You can also buy a new water heater on Easy EMIs at over 1.5 lakh partner stores across 4,000 cities, including Reliance Digital, Croma, and Vijay Sales.

What are the different types of water heaters?

Choosing the right water heater involves understanding the various types available. Here are five main types of water heaters:

  1. Storage water heaters: Storage water heaters are common in homes, featuring an insulated tank that stores hot water.
  2. Instant water heaters: Also known as tankless water heaters, instant water heaters heat water directly without a storage tank. They provide hot water only when needed, making them energy-efficient by eliminating standby heat loss.
  3. Solar water heaters: Solar water heaters use solar panels to capture sunlight and convert it into heat. They are highly energy-efficient and environmentally friendly, relying on renewable energy.
  4. Gas water heaters: Use natural gas or propane to heat water, available in both storage and tankless models. They are often more cost-effective than electric heaters, especially where gas is cheaper.
  5. Heat pump water heaters: Heat-pump water heaters use electricity to move heat from the air or ground to heat water, making them highly energy-efficient.

If you want to replace your water heater, visit any of Bajaj Finance's 1.5 lakh partner stores — like Vijay Sales, Croma, Reliance Digital, and more — across 4,000 cities, including Tier 2 cities like Jaipur, Lucknow, Kochi, Bhopal, and more in India. Choose your preferred model, then use the Bajaj Finance Insta EMI Card or Bajaj Finance Easy EMI Loan to finance it. Convert the cost into Easy EMIs that suit your monthly budget and enjoy zero down payment on select models. Check your loan eligibility online in minutes so you know exactly what you can get before you step into the store.

How do different types of water heaters compare?

Comparing water heater technologies helps you choose between instant electric models, storage geysers, gas units, and solar systems based on running costs and installation requirements.

What features protect water heaters in high-rise buildings and hard water areas?

Water heaters installed in high-rise apartment towers must endure high pressure from hydro-pneumatic booster pumps without leaking or bursting inner tank seams.

Understanding technical protection features prevents inner tank corrosion and structural failure caused by mineral-heavy municipal water supplies.

  • 8 Bar Pressure Rating: Standard geysers handle 3 to 4 bar pressure, but high-rise apartments require reinforced tanks rated at 8 bar.
  • Corrosion-Resistant Coatings: Vitreous enamel or titanium glass-lined tank coatings protect interior metal walls against hard water oxidation.
  • Magnesium Anode Rods: Sacrificial anode rods attract corrosive salts away from tank walls, extending internal component lifespan by 3 to 5 years.
  • Thermal Cut-out Switches: Dual thermostats prevent water overheating above 75°C, eliminating accidental scalding risks and thermal stress.

Tips for purchasing and installing your water heater

When purchasing and installing a water heater, there are several important factors to consider to ensure optimal performance and safety. Here are some tips:


  1. Determine your hot water needs: Assess your household’s hot water requirements to choose a water heater with the appropriate capacity. For larger families, a higher capacity unit is essential, while smaller households can opt for compact models.
  2. Consider energy efficiency: Invest in an energy-efficient water heater to save on electricity bills. Look for models with high star ratings or energy-saving features. This not only reduces your energy consumption but also lowers your environmental impact.
  3. Check safety features: Ensure that the water heater comes with essential safety features such as automatic shut-off, thermal cut-off, and pressure release valves. These features protect against potential hazards like overheating and pressure build-up.
  4. Professional installation: Hire a qualified professional to install your water heater. Proper installation is crucial for the safe and efficient operation of the unit. A professional can also ensure that all safety regulations and manufacturer guidelines are followed.
  5. Regular maintenance: Schedule regular maintenance for your water heater to keep it functioning efficiently. This includes cleaning the tank, checking for leaks, and inspecting the heating elements. Regular maintenance can extend the lifespan of your water heater and prevent costly repairs.

For a reliable option, consider V Guard geysers, known for their quality and efficiency.

What are the prices of water heaters in India?

Choosing between an instant water geyser and a storage model depends heavily on whether you need fast, low-volume hot water for kitchen sinks or continuous high-volume water for family bucket baths and rain showers. Instant geysers use high-wattage heating elements (3,000 W) to heat water rapidly as it flows through a compact 3L to 6L tank. 


Conversely, storage geysers use 2,000 W elements to heat a larger volume of water (10L to 25L+) and keep it hot using high-density polyurethane foam (PUF) thermal insulation. Modern smart models also include Wi-Fi control, smart scheduling, and advanced titanium or Blue Diamond glass-lined tank coatings that prevent mineral scale buildup in hard water areas.

How do I choose the best water heater?

To choose the best water heater, select between an instant geyser (for fast, low-volume kitchen use) and a storage geyser (for multi-person bathing). Match tank capacity to your family size, choose a 5-star BEE energy rating to cut power bills, and ensure an 8 bar pressure rating with corrosion-resistant glass-lined tanks for high-rise apartments and hard water conditions.

The best water heater to buy depends on your household size and budget. For small families and quick showers, the Havells Monza EC 15L 5-Star Storage Geyser offers excellent value at Rs. 8,490. For larger households and hard water areas, the AO Smith 25L 5-Star Geyser priced at Rs. 12,999 provides superior corrosion protection and long-term heating durability.

Select a water heater heating element based on your water quality and appliance wattage requirements. For hard water areas containing high mineral content, choose heavy-duty glass-lined coated or Incoloy 800 heating elements rated at 2,000 W for storage geysers or 3,000 W for instant geysers, as they resist scale accumulation and prevent premature element burnout.

Choose water heater capacity based on your household size and daily usage habits. A 3L to 6L instant geyser suits kitchen sinks and single users. A 10L to 15L storage geyser works best for small families of 2 to 3 members, while a 25L or larger storage model is ideal for households of 4 or more taking back-to-back bucket baths or long rain showers.
