Gas Geyser vs Electric Geyser – Which One Is Better?

If you are planning to buy a geyser for the first time, it can be daunting to identify whether a gas geyser is better or an electric geyser?

In this article, we have listed the pros and cons of both these kinds of geysers, which helps you make a better purchase decision.

What is a gas geyser?

Gas Geysers use LPG for heating the water, and they heat the water immediately and make sure that there is no shortage of hot water supply. However, when compared to electric geysers, gas geysers are less efficient.

A gas burner is placed under the tank, and the hot water is delivered through the pipes. Storage of gas geysers is inefficient due to the heat loss through the tank’s walls and exhaust gases. With its constant supply of warm water, a gas geyser is constantly losing energy or using it.

Advantages of gas geyser

  • You can control the heating level and rate.
  • Power is preserved because of the constant heat supply. If you use the hot water immediately, you will save a lot of energy.
  • It is perfect for big families.
  • Repairing a gas geyser is not hard at all.
  • The lifespan of gas geysers can easily be twice as long as that of electric ones.
  • Gas geysers do not require electricity to run.
  • You can run the geyser with both natural gas pipelines and household cylinders of LPG.

Disadvantages of gas geyser

  • It should have a separate place where you can keep the LPG cylinder and an adequately ventilated bathroom
  • They don’t have a storage option. The geyser is old-fashioned.
  • Its life span is short because gas burners break often.
  • The installation of this system is complicated and requires a professional plumber.
  • The burning of LPG or natural gas in a gas geyser releases carbon monoxide into the air, causing pollution
  • With the energy crisis and rising gas prices, gas geysers are becoming increasingly expensive.

What is an electric geyser?

In comparison with gas geysers, electric geysers are more convenient. An electric geyser works by converting electricity into heat energy using a copper coil. Although the coil used to convert electricity has changed over the years, the principle of operation has remained the same, and it works on the principle of convection.

Advantages of electric geyser

  • It’s very safe
  • Easy Installation
  • It saves space compared to gas geysers
  • It does not emit carbon monoxide
  • With a 2-3 years warranty, you can easily stretch it up to 5-7 years.
  • It generated no pollution.

Disadvantages of electric geyser

  • An electric geyser requires electricity to run.
  • They are expensive to purchase and maintain.
  • Blow-offs caused by short circuits can be dangerous.

Gas geyser vs electric geyser


An electric geyser is best suitable for large families because it comes with large tanks and serves the hot water need of your entire family. On the other hand, gas geysers have the minimal capacity, and multiple such geysers need to be installed to serve a large family.


When it comes to safety, both geysers have their own set of pros and cons. Gas geysers have flame sensors that will indicate when to turn off the gas, and a water flow sensor ensures enough water flow is present for the heat exchanger to function correctly. However, there is a chance of a gas leak happening in the case of a gas geyser. Similarly, electric geysers have an auto cut-off feature to save electricity and store water. However, when a short circuit happens, it can cause a blow-off.


Gas geysers are more efficient, as they heat the water quickly, and no additional energy is needed to maintain the temperature of the water. On the other hand, electric geysers are also efficient (only when it has a right-size tank). Overall, gas geysers win in terms of efficiency.


When it comes to performance, electric geysers are more consistent. However, electric geysers cannot provide hot water when there is a power cut. On the other hand, gas geysers can heat up to 50 gallons of a tank in an hour, and the recovery rate is also fast. Moreover, one can use gas geysers even when there is a power cut. So, gas geysers perform better compared to electric geysers.


Though electric geysers cost less than gas geysers, gas geysers’ lifespan is more extended than electric ones. Electric geysers can last up to 8-15 years, whereas a gas geyser can last up to 20 years. With the replacement of parts, the lifespan can be further increased for both the geysers.


Electric geysers require minimal maintenance to remove the sediments from the tank. In contrast, gas geysers require much maintenance, as the parts are complex. Gas geysers need to be maintained every month to ensure proper performance.


Though the initial purchase cost of the gas geysers is very high compared to the electric geysers, the operational cost is less. Hence gas geysers are winners in terms of pricing (in the long-term).


Now that you know the key differences between gas and an electric geyser, we assume this post helps you make an informed buying decision. Moreover, if you are a small family with minimal heating requirements, we recommend you buy a gas geyser. If not, an electric geyser is the best option.
