What is a Water Heater/Geyser?

The water heater is also called a geyser. It heats the cold water that enters your home, connects to your water pipeline and supplies hot water whenever you need it for bathing, washing dishes, or cleaning.

Just think of it as a large, smart kettle that heats water for your entire home. But instead of warming just a few cups at a time, it heats many litres at once. In the winter season, when tap water becomes too cold, the water heater or geyser works silently in the background and gives you warm water.

What Are the Three Main Types of Water Heaters?

In the market, there are three main kinds of water heaters: storage heaters, instant heaters, and gas heaters. Each has its own benefits, so knowing how each works will help you decide what is best for your situation.

Storage Water Heaters (Most Popular)

You can see storage water in most homes. It is one that has a tank that stores and heats water when the geyser is turned on. The tank is filled with cold water and heated using electricity. This type of tank keeps the water hot until you use it.

These types of heaters are ideal for large families, especially if a lot of people take baths at the same time. If you have a family of three or more, the V-Guard 25L, AO Smith 25L, or Havells 25L are all good choices because they consistently produce hot water.

Storage geysers require some wall space, and they keep the water hot throughout the day, which consumes more power. However, they are dependable, safe, and perfect for homes that use a lot of hot water.

Instant Water Heaters (Compact Space-Saver)

Instant water heaters, also called tankless heaters, are very compact devices. They do not store water. Instead, they heat water instantly when you turn on the tap. Their greatest advantage is that they take up very little space which makes them ideal for bathrooms and kitchens with limited space.

In case you live alone, or if you live with just one more person, or if you want to install a geyser in your kitchen, instant heaters like the Bajaj Splendora 3L, Orient Electric Aura Instant Pro 3L, Lifelong 3 litre Instant Geyser or Racold Pronto Pro 3L are very useful. While they provide endless hot water, the flow of the water is limited, so they may not be suitable for large families taking multiple showers at the same time.

Gas Water Heaters (Ideal for Power Cuts)

Gas geysers use LPG or PNG to heat water. They are fast, powerful, and work even during power cuts. If you live in an area with frequent electricity issues, a gas water heater can be very helpful. However, you must install them in a well-ventilated space to avoid safety issues.

Brands like Havells and Bajaj make reliable gas geysers that offer quick heating and lower running costs compared to electric models.

How to Choose the Right Size for Your Family?

The biggest mistake people make is buying the wrong size geyser. If it’s too small, you will run out of hot water quickly. If it’s too big, you waste electricity.

• For a family of one or two people, a 10–15 litre storage geyser usually works well.
• For three to four people, a 25-litre geyser is perfect.
• Larger families may need 35 litres or higher.

Instant heaters do not have storage capacity, but their power rating matters. A 3kW model is great for kitchens, while a 5kW model is better for bathroom showers.

Why Energy Efficiency Matters?

Water heaters are used almost daily for months, so they are long-term expenses. You can save a lot on your electricity bill if you choose an energy-efficient model.

Always look for the BEE star rating. A 5-star geyser uses the least electricity. Brands like AO Smith, Havells, and V-Guard offer some of the best energy-efficient geysers in India.

Small habits also help. You can switch on your storage geyser only 20–30 minutes before bathing instead of keeping it on for hours. Setting the temperature between 50–60°C also saves electricity and keeps the water comfortably hot.

Installation & The Safety Rules You Should Never Ignore

Most people don’t take the installation process seriously, but it is one of the most important and safest steps. The geyser must be installed on a strong wall. In order to make repairs easily, it should be situated in an easy-to-reach location.

Make sure the model you choose has an ISI mark, an auto shutoff, and a pressure release valve. A geyser with these features is protected from overheating as well as buildup of dangerous pressure.

For gas geysers, proper ventilation is a must. Always call a trained technician. Never try to install a geyser yourself.

Final Thoughts

There is no need to worry about choosing the right water heater. The decision becomes easier when you understand the different types and know what your family needs.

For families with three or more members, a 25-litre storage geyser from V-Guard, AO Smith, or Havells will be perfect. You can save space and money by choosing an instant model from Bajaj, Orient, or Lifelong if you live alone or want a geyser just for your kitchen. And if your area has regular power cuts, a gas model from Havells or Bajaj will keep your showers warm without waiting for electricity.

A good water heater is more than a machine. It adds comfort to your daily routine and makes your winter mornings pleasant. With this guide, you can pick the best geyser that suits your needs, saves money, and lasts for years.
