Havells Water Heater & Geyser Buying Guide

Different types of water heaters

They are the most common type of water heater. The storage water heaters have a large reservoir of hot water that is ready to be released whenever you turn on the faucet.

They can be either gas-powered, which is more economical, or electric-powered, which consumes electricity. 

They must be heated continuously and have an electronic thermostat that cuts off power to the heating coils when the temperature reaches optimum.

It uses energy to heat the water even when you’re not using it. This makes it more costly to maintain.

You can visit this guide to know more about different water heater types.

Water heaters for instant use

Instant Electric Water Heaters 

These heaters are also known as on-demand water heaters. They do not need a storage tank. As an alternative to storage tanks, tankless water heaters are becoming more popular.

It works by turning on the hot water and activating an electric-powered heat exchanger that heats the water quickly. Tankless units heat water only when you need it, rather than heating water continuously in a tank.

Tankless units are more efficient than traditional storage water heaters and therefore use less energy. A tankless system is more expensive than a heater that has a tank.

Instant Gas Water Heaters 

These tankless or on-demand water heaters can be run on either liquefied petroleum gas (LPG) or liquefied natural gases (LNG).

It activates a gas-powered heat exchanging unit that heats the water quickly by turning on the hot water. They are more efficient than instant electric water heaters and use less energy.

Heat pump water heaters

Heat pumps heat water by transferring heat from the air to heat. The heat pump captures energy from the air and returns it to the heat pump’s tank.

It uses electricity to transfer heat from one location to the next, rather than generating heat. This makes the electricity consumption much lower, at just one-fourth of the cost of other water heating devices.

They are, in other words, three to four times more efficient than electric water heaters. Before you buy a water heater, here are some things to consider.


1. Tank vs. Tankless

There are two types of tank water heaters: There are two types of tank water heaters: electric and gas. They keep the inner water warm by being insulated.

It also has a thermostat that regulates the temperature. The tankless water heaters are energy-efficient, convenient, and provide endless hot water. It doesn’t store warm water but heats it only when you require it.

2. Energy efficiency

An energy-efficient water heater is essential for maximum energy efficiency and cost savings. An energy-efficient product can help you reduce your electricity bills by as much as 60%.

3. Size/Storage capacity

Size and space of water

You should choose the right size water heater for your family on the basis of the members. The water heater’s size determines its storage capacity. It is also important to verify the water heater’s capacity for hot water flow.

4. Design preferences

Design and preferences

There are many water heaters on the market. But you need to choose the one that best suits your space. There are many options available in terms of size, shape, and design.

5. Guarantee

There are many brands that offer different warranties for their products. Havells offers a 7-year warranty on the tank and 2+2 years bonus warranty on glass-coated heating elements. Thus, you get 2 years of bonus warranty, that’s something nice about Havells which everybody prefers.

6. Budget

It is important to know the annual operating costs and maintenance for a water heater before you buy it. To find the best water heater, compare them according to their quality, price, and features.

Direct-Fired vs. Indirect Water Heaters

Water heaters, regardless of whether they are tank- or tankless-type units, generally fall under one of two categories: indirect-fired or direct-fired.

  • Direct-fired heaters heat the water directly using the heat from a flame. These units are commonly used in homes that have warm air furnaces. In direct-fired heaters, fuel is what it will consume in a combustion chamber under the water storage tank. Then hot flue gases heat water in the tank.
  • Indirect-fired water heaters heat hot water through a furnace or boiler and heat it by passing it through a heat exchanger in the storage tank. The storage tank stores energy which allows the furnace to turn on and off more often. This can help you save money and energy.

Fuel Type

Another important factor to consider when choosing a water heater is the fuel source. There are many hot water heaters that can be used for electric, gas, propane, or oil. Each one has its advantages and disadvantages.

  • Although liquid propane water heaters require the same venting requirements as natural gas, they also need a storage tank for regular fuel deliveries.
  • Natural gas units quickly produce hot water and come in a variety of sizes and models. However, they must be vented through a chimney or wall.
  • Although oil water heaters are faster than other methods of producing hot water, there are fewer models to choose from.
  • Although electric water heaters can be installed quickly and don’t require any special venting, they consume more energy than other energy sources.

The Process of Installing a water heater

You may be able to do the job yourself if you’re replacing an existing water heater. Replacing an old water heater with a newer comparable model is something a DIYer may be able to accomplish.

If the fuel type, venting, voltages, and fuel match, you can simply turn off the gas and electrical, shut down the heater, disconnect the system and drain the tank.

O’Brian says, “Be aware that connections between an old and new unit might not be in exactly the same place. Therefore, some repiping may be necessary.”

To determine if any modifications are necessary for straight swaps, compare the specifications of your new unit with the locations of the connections from your old model.

Also, a new installation of a water heater will require running gas lines, setting up electrical and proper ventilation. It should be left to professionals.

Take into account your capacity & requirements

capacity & requirements

Tank water heaters can hold up to 40, 50, 55, or more gallons. The number of people in your home and peak water use will determine the size tank you purchase.

For example, a family of four might use several showers and run the dishwasher. They also may wash one load of laundry per day. This would consume 100 gallons of hot water or more. However, a household doesn’t need a 100-gallon tank.

Storage tank water heaters should be considered the FHR rating. This is the maximum amount of water a heater can heat in one hour on the basis of a full tank. The EnergyGuide label will show the FHR. 

Water heaters below 55 gallons have an efficiency boost of 4 percent. Water heaters above 55 gallons have efficiency gains between 25 and 50 percent, depending on whether they are condensing or heat pumps.


Don’t assume that your old water heater will be able to fit in the new one. Some newer models might be larger or taller due to heavy insulation or other efficiency improvements.

The tankless water heaters don’t have a lot of water. Therefore, the GPM rating (gallons per minute) is what you should be looking for.

This number tells you how hot the heater can produce in a given time period. GPM is the rate at which the heater can produce hot water. 

A tankless water heater that can deliver more hot water to large families with multiple bathrooms will be necessary. For example, a typical shower can use up to 2.5 GPM.

The newer washers can wash between 7 gallons (front loader) and 19 gallons, while older washers can use 32 gallons. Calculate your washing needs accordingly.[/su_box]
