Within a year, we frequently find serious water heater problems. These issues arise because we do not thoroughly research or examine the type of water heater required for our home before purchasing one. In this article, we’ll discuss how to choose the right water heater for your home.

Types Of Water Heaters

1. Conventional Storage Water Heater

Traditional storage water heaters provide a ready hot water supply (storage tank) that is sufficient for daily use. However, there are some situations where the need for hot water rises, such as when guests are in the house. You won’t have to wait longer for your shower time.

When you turn on the system, the water in the storage tank will be heated, and you will have a steady flow of hot water until the timer runs out. Hot water will be available to the entire family. You can choose between a 10/15/25 liters water heater depending on the number of users in your family.

Nowadays, the Storage Water Heaters available in the market are compact, portable, and energy-efficient, with several safety features, progressive LED indicator, and Titanium Armor technology for rust-proof tanks.

2. Instant Electric Water Heaters

Instant Water Heaters heat the water without storing it, allowing you to have hot water in a matter of seconds. They are also known as Demand-type water heaters. When you turn on the faucet, the cold water is routed through a pipe to the tankless unit, saving lots of energy.

Tankless water heaters are gaining popularity worldwide as a viable alternative to traditional storage tank devices. When you switch on the hot water, an electric-powered heat exchanger heats the water swiftly. Tankless devices heat water only when needed, rather than constantly heating water in a storage tank.

As a result, they use less energy than traditional storage water heaters. On the flip side, a tankless system might be substantially more expensive than a conventional water heater with a tank.

3. Instant Gas Water Heater

Gas water heaters run on gas, liquefied petroleum gas (LPG), and liquefied natural gas (LNG). These water heaters get their supply through gas pipelines/cylinders and are highly energy-efficient.

It uses a gas burner at the bottom of the tank to heat it, with a vent or chimney to release the carbon dioxide and water vapor outdoors.

Gas Heaters are equipped with several safety measures such as shock-resistant ABS outer bodies, temperature-indicating dials, corrosion, and fire-retardant cables. Gas-powered heaters are more costly than electric heaters but more efficient.

4. Heat Pump Water Heater

Heat pump water heaters are a type of traditional storage water heater. In this water heater, heat isn’t generated directly by an electric heating element or a gas burner; instead, it moves heat from the air to the water.

It absorbs energy from the ambient air and returns it to the heat pump’s water tank. Instead of generating heat, it uses electricity to transfer heat from one place to another.

As a result, the electricity consumed is much lower compared to other water heating devices, and its operating costs are also reduced. In simple words, they are 3 to 4 times more efficient than electric water heaters.

5. Solar Water Heater

Solar Water Heaters, as the name implies, are environmentally friendly appliances that serve their purpose and also promote sustainability. Using a solar thermal collector, they transform sustainable solar energy into heat.

A roof-mounted cell collects the sun’s heat and converts it to an anti-freeze-like fluid in a closed-loop system that leads to the water tank in these heaters.

6. Immersion Water Heater

If you are looking for a low-cost water heater, Immersion Water Heaters are the most popular and convenient heating appliances that will provide quick hot water in the most energy-efficient and safest way.

Immersion Rod Water Heaters are the safest option if you’re staying in a hostel because they’re portable and small enough to fit in any storage space.

7. Air-Water Heaters

The air-water heater uses less electricity and generates heat from the air. Using air-water heaters can help you save up to 60% on your electric bill.

Factors to be considered during the selection of Water Heaters:

Consider the following factors while choosing the right type and model of water heater for your home:

1. Fuel Type

The type of fuel or energy source you use for water heating impacts the annual operating costs and the water heater’s size and energy efficiency. You can use different energy sources to heat the water in your home.

Examples include natural gas, liquid propane gas (LPG), electricity, solar, and geothermal energy. Each has benefits and drawbacks that make them more or less suitable for your application.

2. Size and Orientation

You’ll need an appropriately sized water heater that can easily fit in your installation area to deliver enough hot water for your household while also maximizing efficiency.

It is crucial to consider the orientation (Horizontal Left/ Horizontal Right Mount) as a consideration of the plumbing when purchasing a water heater.

3. Storage Capacity

The size of the water heater should be determined by the family’s total number of people. The storage capacity of a water heater is determined by its size, and it is vital to monitor the water heater’s capacity to provide a consistent hot water supply for all family members.

4. Energy Efficiency

Before buying a new water heater, it’s a good idea to find out how energy-efficient it is. You’ll need an energy-efficient water heater to save money on electricity and make the most of your energy. Investing in an energy-efficient product can save you up to 60% on your electricity bill.

5. Cost

Before buying a water heater, calculate the annual operating costs and compare them to the prices of other less or more energy-efficient models.

6. Warranty

Many brands offer different warranty periods for their water heaters. A good brand can give you a warranty of 5 years on the tank and 2 years on the other components against any manufacturing defects.

7. Customer Service

The after-sell service is also very important, so always check the service centers of your chosen brands.


You have many options when choosing a water heater, whether for new construction, renovation or replacing an old unit. Make your decision based on what provides:

  • The best performance and efficiency.
  • The installation cost.
  • Future fuel and maintenance expenditures.
