Are you someone who reaches out to your favourite hoodie and puts on their comfiest socks as soon as the temperature outside drops a few degrees? Winters can be enjoyable for some but can be troublesome and harsh for others. If you belong to the latter and find yourself looking for room heaters to warm up your home, we’ve got the perfect room heater buying guide for you. We will help you choose a room heater, right from explaining its various features to different safety measures. 

Choose the Right Room for Your Home

The type of room heater you want has a direct relation to the size of your room. A small room with low ventilation tends to have a higher temperature as compared to a large room with many windows for ventilation. Rooms with many windows or air ducts, regardless of size, tend to be colder than rooms that don’t. This is why these rooms require a room heater.

It is also important to keep in mind the amount of empty space in the room. It is recommended that you keep room heaters at least 2 feet away from any furniture, clothing, bedding, or rugs. 

Types of Room Heaters

Now that you know where you want to place your room heaters, it’s important to understand the different types of room heaters and their various features. This guide will help you in buying the right room heater to suit your needs.

Oil-filled Room Heaters

In this type of heater, oil is heated inside the machine and the heat is distributed around the room with the use of large fans. This is convenient because it prevents suffocation and skin dryness caused by regular heaters. It also protects the machine from being overheated.

Heat Convector

Heat convectors are a type of room heater that uses convection to spread the heat around the room with the development of fluid or gas. They are also comparatively smaller in size and beneficial for Indian households that experience winters only for a few months in the year. In this way, you can keep them away after the season has passed. Here’s everything you need to know about heat convectors.

Quartz Room Heaters

If you’re looking for quick and speedy room heating, quartz room heaters are a perfect choice. Crompton’s quartz heater is equipped with two quartz tubes that get heated quickly and help in spreading the heat faster. You can also regulate the temperature according to your preference.

Halogen Room Heaters

With increased heating efficiency and lower energy consumption, halogen room heaters are a convenient choice that also has a wide angle auto oscillation which spreads the heat to every corner of the room. Learn more about Halogen heaters with our detailed guide.

Ceramic Room Heaters

Crompton’s ceramic room heaters have a rust-free reflector with a 1000-watt ceramic heating element, which ensures the spread of heat across the room. 

Safety Measures the Room Heater

Most of Crompton’s room heaters come with a safety grill that locks the heating element, which helps keep it out of the reach of children. If not monitored properly, portable heaters can easily become fire hazards. Therefore, it is essential to consider the safety of a space heater first. In order to significantly reduce the risk of fires, Crompton’s room heaters come with the following safety norms tested and approved as ISI standards. Our quartz and halogen room heaters come with Tip Over Protection safety features where the machine will shut off the heating element in case it gets knocked down. Always follow the safety tips while using a room heater.

Humidity and Oxygen Levels

Fan and rod heaters are known to reduce the oxygen levels present in the room which can cause dryness and suffocation. This is because they cause dry heat and reduce the oxygen levels in the room. In this case, Crompton Insta Fervor room heaters are the best choice as they don’t involve the burning of oxygen. Regular heaters also reduce the humidity levels in the room, which can cause dry eyes and nasal blockage, which can be quite inconvenient and harmful. If you have a newborn baby or a senior citizen in the house, you need to purchase an oil-filled room heater.


Everybody loves enjoying a warm and cozy sleep during winter, however, a noisy room heater can kill your sleep. This is why it is important to check the noise levels of your room heater before you make a purchase.

Room Heater for Asthmatics

In other countries, gas-equipped room heaters are quite common, but this can be a problem for asthma patients. Fan and oil room heaters are generally safe and are the best choice for asthmatics.


Portability is very convenient for a household with few members. In this case, you can choose room heaters that are small and lightweight and can be easily moved from one room to another. 

Energy Efficiency

In your search for the perfect room heater, you may come across heavy-duty heaters with fancy features and designs, but they can take a toll on your electricity bills. Always look at the energy efficiency of the room heater before buying it. You can easily calculate how much electricity your room heater consumes.


The size of the room heater your wish to buy is completely dependent on the size of your room. The general rule is that 10 watts of power should cover every square foot area in your room. This means that a 1500 W room heater can effectively warm up a room of 150 square feet.
