Different Types of Room Heaters in India – Best Room Heaters you can Purchase

If you want to heat your room, there are multiple ways you go by this requirement. Room heaters and blowers are the easiest way, especially for people living in regions which only see a few months or weeks of winters. If you live in a cold region permanently, you should totally invest in a central heating system to make sure you stay warm and cozy no matter which room you are in. Central heating systems are also much more effective than heaters in every single room. So, if you are someone who lives in the hills and other colder regions, think about getting a central heating system installed.

For the rest of us, getting a room heater is the best idea. They are portable and can be moved between rooms easily, and storing them for the next winter also proves easy and convenient.

So, which room heater should you aim for? Should you get a blower instead? Let us see the different types of room heaters in India and what they bring to the table and which one might work well for you.

Types Of Room Heaters – Different Formats of Room Heaters

One of the first step to buying the best room heater in India is to decide what kind to purchase first. There are 3 different types of room heaters, along with options in hot air blowers as well. Let us look at the different types of room heaters in India.

  • Convection Room Heaters – Uses the principle of convection to heat the room. A coil or panel is used for heating, while a fan is used to spread the warm air across the room.
  • Conduction Room Heaters: Uses a metallic coil that glows bright and starts to slowly spread out the heat.
  • Radiant Room Heaters: Uses the principle of infrared radiation to heat the room. Heat rays generated heat the surfaces around your room directly as they hit them.

Now, that said, there are different variations of room heaters that are available within these formats. The three mentioned above are the ways and methods room heaters use to heat the room. Within these, there are different kinds of room heaters that are categorized.

For example, radiant heaters can be of multiple types. Both these two heaters are examples of radiant heaters.

Halogen Radiant Room Heater

There are heaters that use all three methods to heat the air around your room. Heater mechanisms that use a mix of radiant heat, conduction, and convection to help you last the winters with ease also are readily available on the market. They are more devised towards people living in colder regions however.

Besides that, there are also multiple sub-category of room heaters that use different methods to heat the room. You can find a mix of these different styles of room heaters, or find some appliances that work only on one method to help you heat your room.

  • Fan Heaters – Ceramic heaters, convection heaters, blowers
  • Infrared Heaters – Halogen heaters, radiant heaters, quartz heaters, outdoor heaters
  • Oil Filled Heaters (OFR) – Oil heaters, oil filled radiators
  • PTC Heaters – Positive temperature coefficient (PTC) heaters

Let us give each of these types of room heaters in India a closer look and understand what they bring to the table and how they differ from each other.

Room Heaters – Types and Comparison

So, as mentioned there can be multiple formats of room heaters. An appliance can use one of the formats, while other can deploy two, even three different methods to get the work done. Each heater can be used for a different purpose and works differently in varying climates.

Let us get into the details.

1. Convection and Fan Room Heaters

Convection room heaters are generally fan-assisted. A coil inside the heater, or a panel, is heated while the fan itself blows all that warm air out into your room. Convection room heaters are quite effective and work really quickly to heat a room.

They are very commonly found, even being probably the most common type of heater, and their portability and efficiency are the reason they perform so well in residential conditions. Making this the most famous one among our list of different types of room heaters in India.

You can easily use a convection heater in really cold climates, as well as in moderate winters. They do not cost a lot and can be easily fixed up if they run into any issue. Some models might even come with a thermostat, or some kind of control that allows you to customize how hot the coil/panel gets, and consequently your room.


  • Better coverage, reaches most parts of the room
  • Almost instant heating as compared to other types of heaters
  • Very affordable to purchase
  • Easy to use and maintain
  • Compact and portable
  • Great for cold regions


  • Consume quite a bit of electricity
  • Overheating is common and can cause the appliance to shut off until it cools
  • Needs to be aimed well otherwise takes longer to heat room.

2. Radiant and Infrared Room Heaters

Radiant heaters are also incredibly common, especially in places where winters do not last long. In these regions, a radiant heater is actually the better, more viable solution. That said, they do heat up a room slower than most other room heaters, however, if you have allergies and such, radiant heaters are a better pick for you.

Radiant heaters use a metallic coil or element that glows bright when the appliance is switched on. The heat slowly dissipates within the room heating it. They are really affordable when compared to other types of room heaters, and do not consume a lot of electricity either.

There are some forms of radiant heaters that are more powerful than the rest. So, do be mindful of that while looking for your desired room heater.


  • Very easy to use and maintain
  • Temperature control allows customized heating
  • Low electricity consumption
  • No-noise operation
  • Very affordable to purchase
  • Perfect for places that see only a few months of winters
  • Best to heat a specific part of a room


  • Will not heat large spaces
  • Slow to work
  • Not an instant heating function

3. Oil Filled Room Heaters

OFR room heaters use diathermic oil that serves as the heat reservoir for the appliance. OFR’s are really effective and efficient, and prove brilliant at heating rooms almost instantly. If you live in really cold regions and would also like to conserve electricity usage, OFR’s are your best bet.

In OFRs, electricity is used to heat up the oil which is then circulated through the fins of the appliance and thrown into the room. This method is highly effective and almost instantaneous. They are easily some of the best types of room heaters, but till the time the oil is heated well, you might not see a lot of heating going on. The oil itself is not used as fuel, so there is no need for refilling it or anything like that.

That said, once the oil is heated well enough, you can turn off the heater and it will continue to function. This is one of the reasons why OFRs are so common, especially in the hills and other cold places in the world. They are noiseless and are perfect to retain humidity inside a room. If you have kids running around, an OFR is a better choice over the other kinds available in the market.

OFRs actually work with the process of convection to heat your room. They can however be heavier than most other types of room heaters, and portability is not its strongest suite.


  • Great for large spaces
  • Best used in really cold places
  • Saves a lot of electricity
  • The oil retains heat, so the room heater works even after it is turned off
  • Highly durable and long lasting
  • Child-friendly
  • Allergy-free
  • Noiseless operation


  • Expensive to purchase
  • Do not provide instant heating
  • Heavy and not very portable

Bonus – PTC Room Heaters, Blowers, Tower Heaters, Portable Room Heaters

Above we talked about the commonly used room heaters. While they are all great and are viable to use accordingly, there are also a few other formats of room heaters that are available on the market. These range from basic blowers to tall tower heaters that you can even use outdoors. Here are a few extra types of room heaters you can find in India.

  • PTC Room Heaters – PTC room heaters are a new innovation. It stands for Positive temperature coefficient (PTC) heaters, and they prove highly effective at what they are made to do, even more so than other types of room heaters. PTC heaters come with specialized heating discs made from ceramic materials. These discs have holes which grants the appliance greater airflow, which in turn helps their heating potential really take off. PTC room heaters are also much safer, much more efficient, and much more effective than its counterparts.
  • Blowers – Blowers are quite commonly found in Indian households. Perfect for moderate winters, blowers can heat up a room within no time. If you have a medium-sized or a small room, a blower might be of real help to you. They are effective, efficient, and extremely durable.
  • Tower Heaters – Now, tower heaters are really niche appliances. If you live in a place that gets really cold during the winters, or you like to sit outside with a heater running beside you, a tower heater might help you out. These are extremely powerful appliances, sometimes crossing 2000W in power, and are great to handle colds below freezing points. Naturally, they take a lot of electricity to run and can be a hassle to fix-up in case it breaks down.
  • Portable Heaters – These are few and far apart. Finding a good portable heater is really difficult. While you can find a handy portable heater easily, a good one is hard to come by. That said, portable heaters are just that, a tiny appliance that can stick into a power socket close to you and provide instant heat in case you need it. They are relatively cheap to purchase, but do not last very long at all.

Room Heaters Comparisons – Which is the Best Room Heater in India?

Now, let us compare the different types of room heaters and see which one is best used against your requirements. While you should totally buy the heater that best suits your needs, fan heaters are some of the most versatile, working well in moderately cold regions, and doing well in really cold areas as well.

Fan Heaters vs Radiant Heaters

While both types of room heaters are great to use and economical, where they are used differs significantly. Fan heaters are very effective and quick to function, while radiant heaters take some time to heat the room. Radiant heaters might not even work on a large room, heating only the section they are placed in. This is where fan heaters come to the rescue, where fan heaters are much quicker to heat a room due to the fan blowing hot air around.

Fan heaters are a little more expensive than radiant heaters, and also tend to use a lot more electricity to function.

Infrared Heaters vs Oil filled Room Heaters

Infrared heaters are not very commonly used in a home setting, but they work really well outdoors. You can obviously have one inside your home as well, but objectively speaking, they perform way better outdoors, or on like a porch or something.

OFRs are great for indoors and large areas. If you live in a place that experiences tons of cold months, an OFR is the best kind of room heater you can get for yourself. Not only will you be able to effectively heat your room, but can also save a ton on electricity since they use the heated oil to warm up a room and requires very minimal power to function.

Both types are great to have and generally noiseless, however, OFRs tend to be a little more expensive, while infrared heaters are difficult to find in stock.

Fan Heaters vs Oil filled Room Heaters

When comparing the two, fan heaters come out to be a better appliance holistically speaking. While OFRs are great for really cold climates, save you money on electricity, and prove a great heating source, their maintenance and price can be difficult for some people to wrap their heads around.

Fan heaters are a lot cheaper than OFRs and also quite easy to maintain. Both of them offer great safety features, but fan heaters can drop the humidity in the room while OFRs will not.

Here is a table comparing the different types of room heaters in India. This will help you understand which one is best suited for your particular requirements.

Now, how to go about looking for and purchasing the right room heater for your needs? This is something you would have to give note to to make sure your purchase is not only informed, but also provide the best possible outcome for you and your family.

Here are a few things to consider when buying a room heater.

  • Children at home? Avoid infrared room heaters.
  • Radiant heaters are great for people living alone.
  • Fan heaters work well in most conditions. They might cause allergies, so do be aware of that. They also take up a lot more electricity due to the heating effect as well as due to the running fan.

  • If you have a smaller room, a radiant heater might help you save money, both during purchase and during operation. In smaller rooms, blowers also work really well.
  • Most room heaters function with some amount of noise. Radiant heaters and OFRs however work in an almost noiseless approach.
  • Room heaters can also alter the humidity and oxygen levels in a room. For heaters that come with an element or multiple elements that lights up, oxygen levels will drop. Make sure you leave the door open when using heaters that use a heated coil or an element.
  • Fan heaters, large heaters, and blowers also cause the humidity in the room to be altered. They can also sometimes cause allergies, especially fan heaters and blowers.
  • Safety should also be a primary concern. Always buy room heaters that are branded and listed with a warranty.

Which Type of Room Heater is Good for Health?

When it comes to room heaters and health concerns, you are not wrong there. If you have kids or pets in the house, you need to be that much more careful with your choice of room heater and the way you use it

As a rule of thumb, any heater that causes environmental changes, besides heating of course, can be considered dangerous for households with kids. That said, you can obviously child proof your room heater by placing it at a height, or simply being around when the heater is on. However, it is best to invest in a room heater that comes with a few safety features and is also good to use around kids.

Basically, some room heaters affect their environment a lot. For example, fan heaters are notorious for causing allergies. They retain dust when they are not running, and as soon as you switch them on, they blow out this heated dust into the atmosphere. This particularly can be bad for your kid. So, if you have kids running around, try to avoid buying a fan heater. Some room heaters affect the humidity in the room, drying out the air and causing breathing issues. Avoid strong radiant heaters to prevent this from happening.

Radiant heaters are great, but if you are not paying attention, the grills on a radiant heater are large enough to fit a hand through, which can obviously be really bad if your kid or your pet get too curious.

From where we stand, the best, safest, and most healthy option to choose is the OFR room heater. OFR room heaters firstly, do not use a lot of electricity. They contain an oil which acts as a heat reservoir. This means there is no dip in the humidity levels of the room, neither do they cause allergies. They are great for large room too, and are rather safe to use as well. Your kid, or your pet, won’t accidently shove their hand into the appliance, you can be sure of that.

So, which type of room heater is good for health? The Oil Filled Radiator, or the OFR room heater easily takes the cake by being exceptionally safe to use and functional, especially in a household with kids running around.

Factors to Consider when Purchasing a Room Heater

As a rule of thumb, here are the few things you should always give a note to when purchasing a room heater.

  • Thermostat control: Temperature control is a must have in room heaters. If you live in a place which sees less then 2-3 months of winters, you can get away with a heater with minimal functions. However, if your heaters sees use most of the year, a thermostat will be really useful to allow for a much better, more comfortable experience.
  • Portability: Room heaters are portable appliances. Come to think about it, only OFRs are tricky to move around, not impossible however. Tower heaters can also be difficult to move, but you can still manage.
  • Wattage and heating capacity: When it comes to heating capacity of a room heater, check its wattage. Higher the wattage, more heating it can perform. Do remember – more wattage also equals higher electricity bills.
  • Heating time: The time it takes a heater to heat up a room is crucial and kind of objective to be honest. If you want your room to get warm asap, get yourself a fan heater, tower heater, or an OFR.
  • Auto turn off: Automatic shut off is a very important feature to have in your heater. Check twice for this feature and if the one you choose does not have it, find another one.
  • Energy efficiency: Heaters can be power hungry appliances. You can easily get really bogged down by electricity bills if you are not being careful. If you wish to conserve electricity as much as possible, get yourself an OFR, they use the least amount of electricity amongst all the different heaters. Or, you can get yourself a radiant heater. They also do not take a lot of electricity, but also function slower.
  • Noise: Noise can be difficult to work with especially if you are planning to leave your appliance on at night. Oil based heaters do not make any kind of noise, radiant heaters are also almost noiseless, while every heater that uses a fan, will make noise.
  • Price: Room heaters are relatively affordable to purchase. Only OFRs, outdoor infrared heaters, and tower heaters are expensive.
  • Aesthetics: This part is totally objective and depends on how well do you wish to design your living space. If you think of room heaters as simple basic appliances, skip this part. If not, you should understand that radiator-based heaters, tower heaters, and low-key blowers look great within most décor.

Frequently Asked Questions (FAQs)

Which type of room heater is best?

That depends on your requirements. How big your room is, how cold your region gets and so forth. In most situations, a fan heater is the best to purchase. If you live in the extreme cold, try getting a tower heater or an OFR. If you live in a warmer region that sees only a few months of winters, a radiant heater could also do the job.

What type of heater uses the least electricity?

OFRs use the least electricity since their primary reservoir for heat is the oil. Some electricity is needed to heat up the oil, but once it is heated, you can turn off the appliance and it will continue to disperse heat into its environment. Radiant heaters also do not take a lot of power to run either.

Which heater is best for room?
