Different Types of Water Heaters

When it comes to choosing a water heater for your home or commercial space, there are several types available in the market, each with its unique features, advantages, and drawbacks.

Understanding the differences between these types can help you make an informed decision and choose the one that best suits your needs and preferences. Here’s a detailed look at the different types of water heaters:

Storage Tank Water Heaters (Geysers)

Storage tank water heaters, also known as geysers, are the most common type of water heater found in homes. They consist of an insulated tank that holds and continuously heats a reservoir of hot water, typically ranging from 20 to 80 gallons (75 to 300 litres) in capacity.

The water is heated by either an electric heating element or a gas burner, depending on the fuel source. When hot water is needed, it is drawn from the top of the tank, and cold water enters at the bottom to be heated.

Storage tank water heaters are available in various sizes, efficiencies, and fuel types (electric, natural gas, propane, or oil).


  • Readily available hot water,
  • simple installation, and
  • low upfront cost.


  • Standby heat losses,
  • limited hot water supply, and
  • potential for sediment buildup in the tank.

Tankless Water Heaters (Instant Geysers)

Tankless water heaters, also known as instant or on-demand water heaters, do not have a storage tank. Instead, they heat water directly as it flows through the unit, using either an electric heating element or a gas burner.

When a hot water tap is turned on, cold water travels through the heater, where it is heated instantly and delivered to the outlet. Tankless water heaters are available in various sizes, ranging from small point-of-use models for a single fixture to whole-house units capable of supplying multiple outlets simultaneously.


  • Endless hot water supply,
  • energy efficiency (no standby heat losses),
  • space-saving design, and
  • longer lifespan.


  • Higher upfront cost,
  • potential for inconsistent water temperature during high-demand periods, and
  • the need for adequate water pressure and flow rate.

Solar Water Heaters

Solar water heaters use the sun’s energy to heat water, making them an environmentally friendly and cost-effective option in suitable climates. They consist of solar collectors (typically flat plate or evacuated tube collectors) mounted on the roof or in a sunny location, and a storage tank.

The solar collectors absorb heat from the sun, which is then transferred to the water in the storage tank through a heat transfer fluid. Solar water heaters can be active (using pumps and controls) or passive (relying on natural convection and thermosiphon).

They often have a backup heating system (electric or gas) for cloudy days or high-demand periods.


  • Significant energy savings,
  • environmentally friendly,
  • low operating costs, and
  • long lifespan.


  • High initial cost,
  • dependence on solar radiation (weather conditions), and
  • potential for freezing in cold climates.

Heat Pump Water Heaters

Heat pump water heaters use electricity to transfer heat from the surrounding air or ground to the water in a storage tank. They work similarly to a refrigerator or air conditioner, but in reverse, using a compressor and refrigerant to move heat instead of removing it.

Heat pump water heaters are highly efficient, as they use electricity to move heat rather than generate it directly. They can be air-source (using indoor air) or ground-source (using geothermal energy from the ground).


  • High energy efficiency,
  • lower operating costs, and
  • potential for integration with space heating/cooling systems.


  • Higher upfront cost,
  • potential for noise (from the compressor), and
  • lower performance in extreme temperatures.

Condensing Water Heaters

Condensing water heaters are a type of high-efficiency storage tank or tankless water heater that captures and reuses the heat from combustion gases. They employ a secondary heat exchanger to extract additional heat from the flue gases, which would otherwise be vented outside.

By condensing the water vapour in the flue gases, condensing water heaters can achieve higher thermal efficiencies, typically around 90% or more. They are available in both storage tank and tankless configurations and can be fueled by natural gas or propane.


  • High energy efficiency,
  • lower operating costs, and
  • reduced greenhouse gas emissions.


  • Higher upfront cost,
  • potential for condensate drainage issues, and
  • the need for proper venting and installation.

Hybrid Water Heaters (Combination Water and Space Heaters)

Hybrid water heaters, also known as combination water and space heaters, combine a storage-tank water heater with a space heating system. They use a heat pump to efficiently heat the water in the storage tank and can also provide space heating or cooling through an air handler or ductwork.

Hybrid water heaters are designed to capture and utilize the heat that would otherwise be wasted during the water heating process. They can be fueled by electricity or natural gas, depending on the model.


  • High energy efficiency,
  • dual functionality (water heating and space heating/cooling), and
  • potential for energy cost savings.


  • Higher upfront cost,
  • the complexity of installation, and
  • potential noise from the compressor and air handler.

When choosing a water heater, it’s essential to consider factors such as household size, hot water demand, energy efficiency, available space, and installation requirements.

Additionally, local climate conditions, fuel availability, and associated costs should be taken into account to ensure the most suitable and cost-effective option for your specific needs.

When Should You Prefer a Gas Geyser?

There are several situations where a gas geyser (or a gas water heater) might be the preferred choice over other types of water heaters:

High Hot Water Demand

If you have a large household or a high demand for hot water, a gas geyser can be a good option. Gas water heaters typically have faster recovery rates, meaning they can heat water more quickly than electric models of the same size. This makes them better suited for homes with multiple bathrooms or high simultaneous hot water usage.

Lower Operating Costs

In areas where natural gas is readily available and less expensive than electricity, a gas geyser can be more cost-effective to operate over time. The cost of natural gas is generally lower than the cost of electricity per unit of energy, resulting in lower utility bills for water heating.

Backup Power Supply

Gas water heaters can continue to operate during power outages, as long as the gas supply is still available. This can be a significant advantage in areas prone to frequent or extended power outages, ensuring you have access to hot water even when the electricity is out.

Colder Climates

Gas water heaters are often preferred in colder regions because they can recover heat more quickly than electric models. This is especially important in areas with lower incoming water temperatures, where the water needs to be heated to a higher temperature to reach the desired output.

Space Heating Potential

Some gas water heaters have the option to be used for space heating as well. These combination units, also known as hybrid water heaters, can provide both hot water and supplemental space heating, making them a more efficient option in colder climates.

Availability of Natural Gas

If your home is already set up with a natural gas supply for other appliances like a furnace or stove, it may be more convenient and cost-effective to choose a gas water heater as well, rather than installing a new electrical circuit or upgrading the existing one.

However, it’s important to note that gas water heaters also have some potential drawbacks, such as the need for proper venting and the risk of carbon monoxide exposure if not properly installed and maintained. The upfront cost of a gas water heater may be higher than an electric model, although the operating costs can offset this over time.

Top Factors To Consider Before Buying A Gas Geyeser

Energy Efficiency Ratings

Knowing how good gas geysers are at saving energy is key to helping you cut down on energy costs over time. These savings are shown through a percentage that tells you how well the geyser turns gas into heat. A higher percentage means the geyser is using more of the gas for heating water, which helps lower your bills.

It’s important to understand these percentages. Gas geysers with an efficiency rating of 90% or more are seen as really good. This means that 90% of the gas used goes straight to heating the water, with only 10% getting lost. Choosing a geyser with a high-efficiency rating might cost more at first, but it can save you a lot of money later on.

Capacity and Size

When looking for a gas geyser, checking how energy-saving it is matters a lot. But, don’t forget to see if it’s big enough for your needs. The capacity, shown in litres per minute (LPM), tells you how much hot water the geyser gives you every minute. It’s important to pick a geyser that can handle the most hot water your family uses at one time. For example, if you have more than one bathroom being used at once, you’ll need a geyser with a higher LPM.

The size of the gas geyser should also fit where you plan to put it. Bigger ones can give more hot water but need more space for safe setup and use. You have to find the right mix of having enough hot water and making sure the geyser fits in your space.

Think about how many people are in your house and when you all use the most hot water. A family of four, for example, might need a geyser that can handle 6 to 8 LPM to make sure no one has a cold shower when everyone is getting ready at the same time. Picking the right size and capacity means you won’t waste energy or water and everyone stays comfortable.

Safety Features

When choosing a gas geyser, it’s very important to look at its safety featuresThis is because gas geysers use fire to heat water, so being safe is very important. Here are the safety features to look for:

  • Automatic Shut-off: This turns the geyser off if there is no water or gas, stopping it from getting too hot or leaking gas.
  • Flame Failure Protection: If the fire goes out by itself, this stops the gas to prevent leaks.
  • Overheat Protection: Keeps the water from getting too hot, so you don’t get burned and the geyser doesn’t get damaged.
  • Pressure Release Valve: Let out extra pressure if there is too much inside, stopping the geyser from exploding.
  • Carbon Monoxide Detectors: Some geysers have these detectors to warn you if there is too much carbon monoxide from the fire not burning properly, keeping you safe.

These features work together to make sure your gas geyser is safe to use, protecting you from dangers that come with gas devices. Always put safety first before looking at the cost or how easy it is to use, to keep your home safe.

Installation Requirements

Before putting in a gas geyser, make sure your area is ready for it. This means checking a few important things to keep everything safe and working well.

First, your room needs good airflow. Gas geysers make gases that need to go outside. If these gases stay inside, they can be harmful.

Next, look at your gas supply. Your house must have a steady gas connection that fits the geyser’s needs. Also, the gas pipe going to the geyser should be big enough to let enough gas flow through.

Another key point is the water pressure at your place. Gas geysers work best when the water pressure is just right. If the pressure is too low or too high, it might not work well or could get damaged. You may need to add something to increase or decrease the pressure depending on your situation.

Finally, check if there’s enough room for the geyser. Gas geysers are available in different sizes. You need to pick a spot where the geyser fits well and you can easily reach it for any fixing or checks.

Following these steps will help your gas geyser work safely and well.

Price and Warranty

When picking a gas geyser, how much you can spend and the warranty it comes with are very important. Gas geysers are key for your daily comfort, so you need to think about how much they cost at first and what kind of warranty they have. These things show how much the maker believes in their product and help protect your money over time.

Here’s what to keep in mind about price and warranty:

  • Cost Now vs. Value Later: Paying more at the start might mean a longer warranty and less money spent on running it.
  • Warranty Time: If the warranty lasts longer, it usually means the geyser is made better and will last longer.
  • What the Warranty Covers: Look for warranties that cover both parts and fixing them, so you don’t have to pay more later.
  • Brand’s Good Name: Well-known brands often have better warranties, showing their products last a long time.
  • Warranty Can Be Passed On:┬áSome warranties can be given to the next owner of your house, making it more valuable if you sell it.

Frequently Asked Questions

What is the difference between a storage geyser and an instant water heater?

A storage geyser is a type of water heater that stores a reservoir of pre-heated water in an insulated tank. It continuously heats and maintains the water at a set temperature using an immersion heating element. This ensures that hot water is readily available whenever needed, but it also results in standby heat losses from the tank.

On the other hand, an instant or tankless water heater does not have a storage tank. Instead, it heats water on demand as it passes through a powerful heating element. When you turn on the hot water tap, cold water travels through the heater, where it is heated instantly before being delivered to the outlet. Instant water heaters only heat water when it is needed, making them more energy-efficient than storage geysers.

How can water quality affect my geyser?

Water quality, particularly hardness, can significantly impact the performance and lifespan of a geyser. Hard water contains high levels of dissolved minerals like calcium and magnesium, which can lead to scale buildup inside the geyser tank or heating chamber.

This scale acts as an insulator, reducing the efficiency of heat transfer and increasing energy consumption. It can also cause corrosion and premature failure of the heating element or tank. In areas with hard water, it is recommended to install a water softener or use a geyser with a glass-lined tank or self-cleaning features to minimize scale buildup.

Should I get a geyser with a thermostatic control?

Yes, it is highly recommended to choose a geyser with a thermostat or thermostatic control. A thermostat helps maintain the desired water temperature by automatically turning the heating element on and off as needed.

This not only ensures consistent hot water temperatures but also improves energy efficiency by preventing unnecessary heating and reducing standby heat losses. Some advanced thermostats even allow you to set different temperature schedules or remotely control the water heater, further optimizing energy usage.

Does my water pressure matter when selecting a water heater?

Yes, water pressure is an important consideration when selecting a water heater, especially for tankless or instant models. Tankless water heaters require a minimum water pressure, typically between 20-80 PSI (pounds per square inch), to function properly and deliver hot water at the desired flow rate.

If your home’s water pressure is too low, the tankless heater may not activate or may provide only a trickle of hot water. In such cases, you may need to install a booster pump or consider a storage tank water heater, which is less affected by water pressure fluctuations.

What is the difference between a geyser and a water heater?

While the terms “geyser” and “water heater” are often used interchangeably, there is a technical difference:

A “geyser” specifically refers to a storage-type water heater that heats and stores hot water in an insulated tank.
A “water heater” is a broader term that encompasses various types of devices used to heat water, including storage geysers, instant/tankless heaters, solar water heaters, and more.

How do I determine the right geyser size for my home?

The right geyser size depends on factors such as the number of bathrooms, the number of family members, and your peak hot water usage.

A general rule of thumb is:

  • For a small household (1-2 people) with one bathroom, a 10-15 litre geyser may suffice.
  • For a medium household (3-4 people) with two bathrooms, a 15-25 litre geyser is recommended.
  • For a large household (5+ people) or homes with three or more bathrooms, a geyser with a capacity of 25 litres or more is advisable.

How do geyser manufacturers determine the capacity or size recommendations?

Geyser manufacturers typically base their size recommendations on industry standards and average household hot water consumption patterns. They factor in variables such as the number of bathrooms, typical family sizes, and peak usage times to provide general guidelines for different household types.

Conclusion – Bringing the Best Geyser To Your Home

When picking a gas geyser, it’s very important to look for one that uses less energy so you can save money. Make sure it’s big enough for your family’s needs. Safety features are also key to keeping your home safe.

The cost of putting it in can change the total price, so think about that. Also, compare how much it costs with the warranty it comes with to get the best deal. By looking at these things, you’ll choose the right option for your money and needs.
