“Thande thande paani se nahana chahiye…” goes a famous bollywood song. While good to sing along, cold water showers are just unthinkable on cold winter mornings or on rainy monsoon days. A good ol’ geyser can be indispensable for that hot water bath to warm you up and soothe your nerves.

But how would you pick out which type of geyser to buy? With various types of geysers available on the market, it can be overwhelming to decide which one best suits your needs. Whether you’re building a new home, upgrading an existing setup, or just replacing an old geyser, understanding the different types of geysers can help you make smart choices.

In this article, we’ll explore the different types of geysers available, their features, and the advantages they offer, helping you pick the right one for your household.

1.Storage Water Geysers

Storage geysers are the most common and widely used type in Indian households. These geysers have a storage tank that heats and stores a large volume of water at a time, ready to be used whenever needed. They come in various capacities, typically ranging from 10 to 50 liters, making them suitable for different household sizes.

How They Work:

Water enters the geyser’s storage tank and is heated by an electric heating element. The thermostat controls the temperature, ensuring the water is heated to the desired level. Once the water reaches the preset temperature, it is stored in the tank until you need it.

  • Pros:
    • Ideal for larger families.
    • Continuous hot water supply for multiple uses.
    • Available in various sizes, offering flexibility based on family needs.
    • Cost-effective and easy to install.
  • Cons:
    • Takes longer to heat water.
    • Consumes more energy to keep the water hot.
  • Best For: Homes with a higher demand for hot water or families with multiple bathrooms.

2.Instant Water Geysers

As the name suggests, instant water geysers heat water quickly, providing hot water almost instantly. These geysers don’t have a storage tank; instead, they heat water directly as it flows through the unit. Instant geysers are perfect for smaller households or situations where hot water is needed for short durations.

How They Work:

When you open the hot water tap, cold water flows through the geyser, which heats it instantly using a powerful heating element. The water is then sent out as hot water.

  • Pros:
    • Quick heating – ideal for emergencies or immediate use.
    • Compact design and space-saving.
    • Energy-efficient as water is only heated when required.
  • Cons:
    • Limited capacity – not suitable for larger families or high water demand.
    • Higher power consumption if used frequently.
    • May not provide consistent hot water if multiple taps are used simultaneously.
  • Best For: Small families or homes with lower hot water requirements.

3.Gas Water Geysers

Gas geysers are another alternative option for homes in India. These geysers use gas as a heating medium to heat water. They are efficient and can provide hot water instantly, much like the instant electric geysers, but with the added benefit of using a more economical energy source.

How They Work:

A gas geyser works by using LPG or natural gas to ignite a flame that heats the water passing through the unit. The gas burner generates heat, and the thermostat controls the temperature to ensure it remains constant.

  • Pros:
    • Cost-effective, as gas is cheaper than electricity.
    • Provides hot water instantly.
    • Energy-efficient, as it only heats the water when needed.
  • Cons:
    • Requires proper ventilation to prevent gas leaks.
    • Can be dangerous if not maintained properly.
    • Requires a gas connection and might not be ideal for all areas.
  • Best For: Homes where electricity costs are high or in areas with a reliable gas supply.

4.Heat Pump Water Geysers

Heat pump geysers are a relatively newer technology in India, but they are becoming increasingly popular due to their energy efficiency. These systems work by extracting heat from the surrounding air and using it to heat water.

How They Work:

A heat pump system works similarly to an air conditioner but in reverse. It absorbs heat from the air, which is then transferred to the water in the tank. This process is much more energy-efficient than conventional heating methods.

  • Pros:
    • Extremely energy-efficient and eco-friendly.
    • Can significantly lower electricity bills.
    • Ideal for use in warmer climates.
  • Cons:
    • Higher initial cost compared to traditional geysers.
    • Not effective in colder climates as it relies on ambient air temperature.
    • Requires space for installation.
  • Best For: Environmentally conscious consumers or those looking to reduce their energy bills.

5.Solar Water Geysers

Solar geysers harness the power of the sun to heat water, making them one of the most eco-friendly options available. These geysers are perfect for regions with abundant sunlight, where the sun’s energy can be efficiently converted into heat for water.

How They Work:

Solar geysers use solar panels to capture sunlight and convert it into heat. This heat is then transferred to the water in the storage tank, providing a free and renewable source of hot water.

  • Pros:
    • Environmentally friendly and sustainable.
    • Low operational cost – only requires sunlight to operate.
    • Reduces electricity bills.
  • Cons:
    • High initial installation cost.
    • Dependent on sunlight; may not be suitable for all weather conditions.
    • Requires a large amount of roof space for the solar panels.
  • Best For: Homes in sunny areas where there is adequate roof space for installation.

Which One Suits Your Needs Best?

Choosing the type of geyser depends on several factors, including the size of your household, your budget, energy efficiency needs, and the availability of resources like electricity or gas.

  • Storage geysers are ideal for large families needing continuous hot water.
  • Instant geysers work best for smaller households or those with limited hot water demand.
  • Gas geysers are great for areas with a stable gas supply and those looking for cost-effective solutions.
  • Heat pump geysers are perfect for eco-conscious consumers looking to save on electricity bills.
  • Solar geysers are the best option for those in sunny regions who want to embrace renewable energy.


Hot water geysers are not a luxury, but a necessity. This guide should help you to select what type of geyser suits you best. So that you continue those rejuvenating hot showers uninterrupted. And yes, by all means “… gaana aaye ya na aaye, gaana chahiye”.
