Determining which is better between a gas geyser and an electric geyser can be challenging, particularly if you are new to the geyser world. However, the best way to determine the better geyser between the two types of geysers is to look at the strengths and weaknesses of the two to know the best one to choose. Gas geyser and electric geyser work differently, and the two of them have their advantages and disadvantages while heating water. In addition, consider the safety of the two types of geysers, the lifespan, cost, efficiency, performance, and how each of them works.
Try to choose the right geyser by answering simple questions without reading any Buying Guide.
Why trust this guide: This article is written by Abdul Khader, who has spent over 4 years installing and repairing both gas and electric geysers in Indian homes. The comparison below is based on real installation calls and running costs, not just manufacturer spec sheets.
Quick answer: For most Indian homes, an electric geyser is the safer, lower-maintenance choice, which is why we recommend it below. A gas geyser can make sense for a large family with heavy hot water use, reliable LPG or PNG access, and a genuinely well-ventilated space to install it outside the bathroom, but it comes with real safety responsibilities electric geysers don’t.
Appliance Avenue Suggestion – Gas Geyser or Electric Geyser Which is Better
Gas geysers come at economical prices, and the cost of water heating is also less by using subsidized LPG. But considering the significant safety risk involved in gas geysers, we do not recommend gas geysers at all; we prefer electrical geysers only.

Gas Geyser
Gas geysers make use of Liquid Petroleum Gas (LPG) for the purpose of heating. These geyser types have no limited power to heat water. Gas geysers provide an incessant flow of heated water and supply immediate heating.
Gas geysers are less power efficient than electric geysers and have a speedy recovery rate. No wonder they are the expedient choice for bigger families. Gas geysers were once popular in cities like Mumbai, Pune, Ahmedabad, Delhi, Bangalore, and Hyderabad.
But people are slowly moving away from it in metros due to gas geyser requirements, like a large bathroom with proper ventilation. But in fact, gas geysers are picking up in tier 2 cities like Vadodara, Borivali, Mysore, Faridabad, Dehradun, Nagpur, Nashik, and Surat. Significant repair queries are clear proof of it.
Types of Gas Geysers
- Instant Geysers or Tankless Geysers:
Needed by those who do not need a large quantity of water at once. In India, most gas geyser manufacturers provide instant gas geysers only. - Storage Geyser ( not available in India ):
Needed by those who need a large quantity of hot water, for instance bath in a bathtub. These geyser types are easy to repair as a result of their simple construction and operation. Storage geysers are well-liked geyser types in the market. These types of gas geysers are very rare in India.
How a Gas Geyser Works
Gas geysers work by heating water, making use of a gas burner located below a big tank from where the heated water is delivered through pipelines. In the course of heating, pressure accumulates in a gas geyser, and the pressure valve intervenes and discharges the pressure.
Gas Geyser Advantages
- You have the power to control the level and rate of heating
- Heating is steady, thereby supporting power preservation. You will conserve a large amount of heat energy if you use the hot water instantly.
- Suitable for a large family
- It is very easy to repair a gas geyser
- You do not need electricity to run a gas geyser
- Can run a gas geyser on both pipeline natural gas and household LPG cylinders
Gas Geyser Disadvantages
To know which is better, a gas geyser or an electric geyser, you also need to consider the gas geyser’s disadvantages.
- Strictly not safe. It can even lead to death. More details are in the next section.
- Require additional space to keep the LPG cylinder, and the bathroom should have proper ventilation
- In India, gas geysers had a very small market. Most gas geysers are instant gas geysers only. Storage gas geyser models are not available. Gas geysers are getting outdated easily
- Small life span as gas burners tend to be damaged frequently.
- Difficult to install and can only be done by experts.
- Gas geyser causes pollution because it releases carbon monoxide into the air in the course of burning LPG or natural gas
- Due to increasing gas prices and the energy crisis, the cost of gas geysers is increasing every day.
- Sediments build up at the base of the tank after using it for a long period of time. You need to get rid of these on a regular basis. You only do this with the help of the drain in the tank.
How Safe is a Gas Geyser?
We do not recommend Gas Geysers, considering their significant safety risk. For the question Are gas geysers dangerous?, our answer is that they carry real risk if installed incorrectly, mainly carbon monoxide buildup in an unventilated space, which is why we don’t recommend them for most homes. Read more at the Hindu and Times newspapers. Because of this reason, very few brands manufacture gas geysers. There are no Havells gas geysers. As the Havells brand stands for safety, they do not manufacture gas geysers. You can not find Havells gas geysers in the market. Irrespective of life risk if you still consider installing the gas geyser, do follow the guidelines below.
- Do not ever install it in a confined area or space such as the bathroom. Install your geyser where there is adequate ventilation.
- Steer clear of keeping the geyser near corrosives, explosives, or inflammables. In addition, do not keep any electric wiring near the geyser.
- Make sure that all the linking pipes are clean, anti-corrosive, and leak-proof.
- Keep your geyser at a height at which you can see the pilot flame easily. If the Geyser is damaged, and even if you turn off the geyser, you can see the flame. It will be a lifesaver.
- Avoid leaving your gas geyser or the tap on for a very long time.
Gas Geyser Efficiency
Since gas geysers sold in India are almost always instant models, they don’t carry the standing heat loss that a storage tank has, they only burn gas while the tap is running. That’s a genuine efficiency advantage over an electric storage geyser. The trade-off is combustion efficiency: some heat escapes with the exhaust gases rather than transferring fully into the water, which is part of why running costs vary so much between models.
Gas Geyser Performance
A gas geyser heats water on demand, without the wait an electric storage geyser needs to warm a full tank. That makes recovery between uses effectively immediate, since there’s no tank to reheat in the first place. It also keeps working during a power outage, which is worth factoring in if your area gets frequent cuts.
Gas Geyser Cost and Lifespan
Gas geysers are less expensive than electric geysers. Bajaj Gas Geyser is one of the best gas geysers that comes under the price of Rs. 6,500. However, as far as lifespan is concerned, electric geysers have a longer lifespan than gas geysers, depending on the owner’s maintenance and the quality of local water.
Electric Geyser
Simply because of the convenience provided by electric geysers, they have become very universal. With an electric geyser, a copper coil is used to convert electricity to heat energy. More than a few changes have been made to this type of geyser, but the fundamental principle is similar.
Types of Electric Geysers
Uses an electric heating element situated in the water tank. In order to reduce heat loss, high-efficiency units feature additional insulation. Two types of electric geysers are available to choose from: electrical instant geysers and electrical storage geysers. Do read more about these filters at Instant Geyser Vs Storage Geyser
Electric Geyser Advantages
- You can install electric geysers nearly everywhere
- An electric geyser is easy to handle
- The energy source needed to heat the water is cheap
- No release of carbon monoxide because there is no burning of fuel
- The speed of heating is very fast
- Longer lifespan
Electric Geyser Disadvantages
- You need electricity to operate an electric geyser. Do read How to Reduce Geyser Electricity Consumption? for more information.
- It is highly expensive to buy and operate
- Short circuit blow-off can lead to possible danger
- Stops working during a power outage, unlike a gas geyser
- Sensitive to voltage fluctuations, common in many parts of India, which can shorten the heating element’s life without a stabilizer
How an Electric Geyser Works
The flow of electricity conveys heat energy to the water contained in the tank, and the water is then delivered all the way through the pipelines. It works on the convection principle. Which is better, a gas geyser or an electric geyser, now that you can identify the types of gas and electric geysers? Which is better, a gas geyser or an electric geyser, will depend on a number of factors, including:
- Cost of insulation
- Cost of buying the geyser
- Space requirement
- Efficiency and requirements of the geyser
- The life expectancy of the geyser
Frequently Asked Questions
Is a gas geyser cheaper to run than an electric one?
Usually, yes, especially on subsidized LPG. But that saving has to be weighed against the extra installation requirements and the ongoing responsibility of keeping it properly ventilated.
Can a gas geyser be installed in a bathroom?
It shouldn’t be installed inside a closed bathroom. The unit itself should sit outside the bathroom in a well-ventilated space, with only the hot water pipe running in. See our Geyser Installation Guide for the full safety guidance.
Why do so few brands make gas geysers in India?
Partly market size, gas geysers have a much smaller share of the Indian market than electric, and partly safety liability. Havells, for example, doesn’t make gas geysers at all, which the brand has positioned as a safety-first choice.
Does a gas geyser work during a power cut?
Yes, since it runs on LPG or piped gas rather than electricity, a gas geyser keeps working during an outage. This is genuinely useful in areas with frequent power cuts, though it doesn’t outweigh the safety trade-offs for most households.
