Imagine a shower in the cold month of December. The very thought of cold water is bound to make most of us shiver internally. A water heater is the ideal solution for such issues, as it heats large quantities of water for the use of the consumer.
Usually, people purchase electronic heaters, which are more appealing to look at and are the most used type of water heater. But in the modern world, due to lack of funds of the modern man, a gas heater seems to be the logical option. They usually cost less as compared to an electric heater, and also cost lesser while in use. The gas heaters also consume about one-third of the electricity consumed by an electric water heater. They are able to heat larger quantities of water in shorter spans of time, as compared to electric heaters. They also function during power failure, unlike electric heaters.
The working of a gas water heater is very simple. It functions on the principle of convection, implying that warm water tends to rise, while cold water sinks. There is an inlet pipe in the heater where the water is allowed to enter the chamber. The heat is provided by the burner under the tank, and the water is heated and slowly rises, while the cold water sinks below it to be heated and rise again. The warm water which rises and is allowed to leave the heater via the outlet!
The condensing gas heater model works as there is a heating unit present which is heated by the flames. The water pipe runs across the heating unit in a serpentine manner, allowing it to absorb as much heat as possible. This allows properly heated water to be produced for use. Such models are very energy efficient, but tend to cost a higher amount.
The way to control the temperature is by varying the amount of gas provided to the mechanism. This is controlled by the ECU (Electric Control Unit), which can either be wireless or be attached to the system in a remote location. This is the way to control how hot the water gets.
The gas water heater is an essential buy, as it reduced the costs for heating water greatly. Kindly refer to our “Buying Guide” in order to clear any doubts you might have about these heaters. It is bound to help you to purchase the Gas Water Heater perfect for your needs. Also we have listed some of the best water heaters in India that you can go for.

Buying Guide For Gas Water Heaters In India
When the thought of purchasing a heater comes into one’s mind, most people primarily still think about the electric heaters. But it has been a while since gas heaters have gained significant importance and people have been eager to consider this option as well. But the lack of knowledge acts as a barrier to the successful purchase of a gas heater.
If you have issues selecting a type of heater, you are not the only one out there who is unaware. A lot of people have this confusing and hence, we have come up with the perfect guide to help you out while you make the decision which shouldn’t be regretful. This guide has all the factors which need to be taken into consideration while purchasing a gas heater.
1. Interiors & Aesthetics (Design)
Gas heaters are not so beautifully built as compared to the electric heaters. You cannot expect these gas heaters to be all stylish and eye catchy but you can for sure expect them to be compact, slim built and be good in terms of savings. The interior of the heater must be in such a way that it should be able to stand a number of effects such as hard water. Hard water is a hindrance upon the heater’s lifespan and durability and hence a heater with corrosion resistant interior must be the first choice.
Though not stylish, a well capable interior must be the choice of users who wish to buy a gas heater. They are extremely compact because they have no storage capacity and provide you instant heating water, leaving no extra requirement for additional storage space. The sleek and compact design of the gas heater is all which makes it attractive enough and self-sufficient.
2. Storage Capacity
You do not need to worry about the storage capacity of the heater because the heaters have no additional storage spaces for the process of storing water and reheating this. The gas heaters work on a complete instant heating functionality leaving no room for an extra area of water storage. You do not need to wait for the water to heat up, as in the case of an electric heater and you will be served with instant water the moment you walk into the washroom and turn on the heater’s switch. This is the impact that falls upon its sleek and compact design. For the instant need and use, these heaters are the best options you got. No tank provision, no reheating, no thermal heat loss, no shortage of heat water and no waiting time. Instant demand for hot water will forever be fulfilled on the spot, without any kind of issues.
3. Ease of Use (Functionality)
The functions, as in the buttons and operating facility of the heater must be simple and easy to understand. Don’t opt for heaters that work in a pretty complex way, making it difficult for you to understand the basic way of using the heater. Heaters are bound to provide you only with the provision of hot water and hence having complex options makes no sense. Irrespective of the age group or gender, a heater must be easy to use by everyone.
The second thing to follow is to get the heater installed by the service center representative of the company and not by any of the local plumbers. The company technician will be knowing all the safety measures to follow and the correct installing process will be known by him in advance leaving no chances of any mishaps. The manufacturers do provide technicians for installation and they will as well provide you with a demo on how to use the heater.
4. Energy Efficiency
You can weigh in the efficiency of the gas heater using the energy efficiency (EF) which indicated how efficient the transfer of heat from the heating element to the water is. You need to go for a higher energy factor because the higher the energy factor provided with the heater, the higher will be the efficiency of the heater. They both are proportionate to easy others in many terms. The most regular energy efficiency of the heater ranges between 0.5-0.6 and some of the higher end models possess the energy efficiency of up to 0.8.
ou must also consider the watts consumed by the heater. This directly affects the heating process as it would determine the speed of the heater. For instance, a heater with the wattage of 4.5KW will work faster as compared to the heater with the wattage of 2.4KW. Knowing them all is always being on the safer side.
5. Flow Rate
The most important factor to consider when we are referring to the tankless heater is the flow rate and not the capacity of the heaters. You need to know and weigh in the flow rate of the resulted output and compare if it is as per your requirement and then decide to purchase the product as per your convenience. The flow rate is generally calculated in terms of GMP also known as Gallons Per Minute. The provision of hot water flow will only be stopped when the heater reaches its maximum heating ability or crosses the threshold. If you wish to have a constant flow of hot water throughout the time you are in the shower, you need to weigh in the exact requirement. You need to have a check on your use and then select the most compatible heater to bring home with you which would be capable of fulfilling your needs.
To start with, you need to check on the durability of the product and then you will be required to check the warranty of the product. These gas heaters generally last longer than the electric heaters which have storage units available with them to store water. You can be assured, if you select on buying a gas heater, they will take you on for a long way but yet, it is always better being on the safer side. You shall consider the warranty provided by the manufacturer which would cover all the expenses and service charges for a fixed period of time.
Another important thing to consider is the brand producing the product. The company plays a very important role, given the quality and warranty of the product. You can always expect out of a reputed company to provide you with a wider period of warranty i.e. 5 to 7 years and lasting after sale services too.
7. Operating Costs
The operating cost of gas heaters is simultaneously less as compared to the electric heater. They consume a lot less energy because they do not store water in a tank and then heat it. Also, gas heaters work on Natural gas or LPG gas, both of which are a lot more cheaper than electricity. The overall operating cost of your appliance is bound to reduce. The LPG gas unit will as well be fixed with the heater which will provide with the heating procedure. The cost of heating, therefore, would vary as per the provisions you have. If you have an Aadhaar subsidy, you will be required to pay around 50 paise per liter of water.
But, if you aren’t an Aadhaar subsidy, one liter of water would cost you around 80 paise. No wastage as well adds on to the factor of operating cost and your costs are bound to reduce. If saving is your prime motive, you must perhaps buy a gas heater.
8. Availability of Accessories and the Spare Parts
Accessories comprise of connecting nipple, two steel ribbed pipes, and a single angle brass valve. Make sure you are able to find these items because they would be required at the time of fixing the heater or for installing the same for the first time. The other parts which you will be needing are the heating element, the thermostat, and the tank. They are actually the interior of the product and the maintenance directly impacts the life of the gas heater.
If the water of your area is hard, your heater will need quicker replacement because the parts will be a lot more prone to damage. This is when you will need quick access to spare parts and accessories. If you purchase a product which is new to the market, it might be possible you face a difficult time gaining your hands on the spare parts. Hence, it is always better to check what all are the spare parts and make sure they are available in the market through an easy medium.
9. Customer Service
Customer service is yet another factor to consider because buying the product will not guarantee a life-long service without issues. You will be going through a lot of phases where you will see your product working in an unexpected way. It might be not in the best of working version, or you will face issues that would need to be sorted. For this, you will need the assistance of the company you bought the product from.
Hence, it is always better to perform a routine check on the customer service of the company. If you decided to go for a model produced by a reputed company, you can be assured the services will be of world class but on the contrary, if you buy a product from an under established company you may face issues regarding its after-sale service. Hence make sure you plan the same well in advance.
The gas heaters are generally economical as they come at lower prices as compared to the electric heaters. You will be able to find a good or compact as well as a self-sufficient heater at a price range of INR 4,000 to 4,500 with an instant capacity of 6 liters. This price range is generally affordable as compared to electric heaters with similar specifications, which are available at the price range of above INR 6,000. Also, make sure you don’t weigh in the price to be the only deciding factor. You must check onto each and every aforementioned aspect and only, then consider the price between similarly performing models. If you have a fixed rather, lesser budget, a gas heater will fit onto your demand as well as your budget.
As a concluding note, stick to the entire list and factors as you will be saving a lot if you buy such a heater, given the economic price, consumes lesser energy and causes zero to no wastage. As you will be gaining reliable access to instant heated water, on demand, without having to change or repair the heater, frequently! Also take into account the after-sale service, availability of spare parts, operating costs and the flow rate.
Benefits over Electric Water Heater
- Energy efficiency: Electricity is not the primary consumption unit as for the gas heaters. They use LPG as the main input, and only, transportation is done through the electric medium. This has a high and direct effect on energy consumption. These heaters are quite energy efficient as compared to the electric heaters which depend entirely upon the electricity for the heating process.
- Price: The gas heaters are highly economic, whereas the electric heaters are a bit pricey. You can find a well working 6-liter gas heater within the price range of INR 4000 whereas you need to invest a lot more in the electric heaters. The way the gas heaters work is actually proportionate to the price. For only the process of heating water, the gas heater is the best option you can go for.
- Heating time: The gas heaters work 3 times faster as compared to the electric heaters. The electric heaters store the water in a tank and reheat them which is why they take a lot of time to heat. Whereas, for the gas heaters, they work on an instant serve basis. They provide hot water on the go and are quicker in the heating process. The LPG plays the most vital role here and the best thing is instant supply on demand. For the lesser use, the households have (than commercial spaces) and for the quick access they provide, the gas heaters are the best option one can select for their homes.
- Compact: Gas heaters do not usually have space for water tanks which makes them compact. Yes, there is no extra provision for a water tank which lessens the consuming area of the product. As for electric heaters, they have a lot of space. Generally, 25 liters to 50 liters of water storage capacity, which in turn makes them heavy and bulky. Saving space is always given importance in middle-class houses. Hence, preferring gas heaters which are generally, highly compact will be the best choice for you, especially considering it’s a long term investment.
- Sleek design: Gas heaters are also sleekly designed along with being compact. They go hand in hand, as less area requirement leads to a lot more sleek design. The electric heaters are a lot fancier, but the sleek design never goes out of the trend. You will forever be fascinated by a product which is sleek irrespective of its nature, or the design trends. So, for the light and sleek requirement of the residents of India, a gas heater turns out to be a great option.
- Lightweight and easy to mount: Because gas heaters are sleek in design and look, they are also lightweight. They are extremely easy to mount to the wall. But, the most important factor to take into consideration is the mounting needs to be done by the company’s representatives and not a regular plumber who hasn’t got the required knowledge.
How To Relight A Gas Water Heater?
When the water passing through the heater needs to be heated, a gas heater uses a pilot light to induce a flame in the gas burner. The lighting of the pilot may not be constant all the time. It has the probability of going off in terms of malfunctions or when the gas frequency is not correct. The good news is, you can relight it yourself. Here is the troubleshooting method:
- You need to start with turning the gas valve off and need to further wait for a few more minutes before you proceed further.
- Now, you need to turn the value to the pilot mode and push down onto a red button below it.
- You now need to hold it down for the gas to pass through it and let the gas flow begin.
- You now need to wait further holding down the button on value till the pilot indicator lights down.
- In the case of manual lighter requirements, a barbecue lighter has to be used to light the end of the supply tube.
- Make sure to keep holding the valve for a minute after ignition.
- If the pilot yet doesn’t light, turn the valve to off, wait for a few minutes and continue with the process all over.
- Now when the pilot is lit and stays lit all the time, turn the control button to the ON.
- This way the burner must lighten up.
- If you still face issues and the burner is not lit, you must contact the service center.
Frequently Asked Questions
The mechanism of the gas heater is built in such a way that it provides hot water on the go. Hence the heaters have a burner at the end, which facilitates the quick and timely stream of heated water. The exact location of the burner is the center of the heater and it heats the water flowing through the reservoir.

There are a number of alarming factors that determine the existing heater’s life has come to an end and it would no longer serve you. We will mention 2 ways of knowing whether your gas heater has exhausted and if it is the time to replace it. The first being the leakage of any kind, look out for water build-up in and around your heater.

If your heater is suffering from any kind of water leakages, it is to be considered as a serious problem and a call for help is to be immediately made. To start with, check for these areas to determine the leakage, cold water inlet, hot water outlet, pressure relief valve, heater drain valve and the bottom of the hot water tank.
If you notice leakages in any of these areas, your heater requires immediate repair or else, it may lead to some serious issues. The problem hers is generally with the water heater and this needs to be replaced as soon as possible.
As the first step, you need to check out for some common things that could generally be faulty in the heating process. Check the pilot light and the gas and see if both of them are switched on. If you find the pilot light off, you may troubleshoot and relight it yourself as explained previously.

However, if you are able to hear anything, is the indicator something is wrong with your heater. There is a possibility you might hear a clicking noise, which is actually situated with the build-up of various kinds of waterborne sediment at the bottom of the water heater.
This might even lead to overheating as the sediments stop the water heating process making the heater body extremely warm. You can, however, correct it, by simply draining the water out the heater to get rid of the sediments.
The gas leak can be determined by the excess of gas usage with is only bound to happen if there is a leak or a number of leaks in the gas. So, yes there is a possibility of gas leaks happening. If you wish to solve it, you can simply choose to replace the fuel piping. Another way you can prevent it is to drain the heater and remove all the debris.
The presence of a lot of particles (sediments) at the bottom of the heater actually slows down the heating process as the heater now needs to heat much more than just water.
