Features to Look for Before Buying a Room Heater

Energy Efficiency

There is not much logic in getting a warmed-up room in exchange for increased electricity bills. 

Once you have already invested in a heater, additional expenses shouldn’t be entertained except for maintenance. 

For this, it’s best to go for a heater that is energy efficient and has energy-saving modes, low wattage, adjustable thermostats, and programmable timers.

Wattage, Heating Capacity and Heating Speed

A room heater with low wattage is a safer bet as they consume less electricity and do not add up to extra electricity bills. 

The heating capacity of heaters must be according to the size of the space you want to heat up. 

For instance, for a room size of 100 – 159 square feet, a room heater of 1500 watts is adequate. 

However, it also depends on heating technology and the home environment.

Safety Mesh/Grill

Safety is one of the prior concerns when buying a room heater. 

A safety mesh along with a cool-to-touch surface must be included in these small home appliances. 

Other advanced safety features like overheat protection and automatic switch-off are also recommended.

Noise Level

The noise level of room heaters must be speculated before buying one. 

Excessive noises can disrupt sleep and other discrete activities. 

A room heater with minimum or no noise is highly recommended for a more soothing and peaceful experience.

Auto-cut Feature

The auto-cut features of room heaters indicate their ability to automatically get turned off when the desired temperature is reached inside the room. 

It is best to go for a room heater with an auto-cut feature as they are a much safer and customized option. 

Otherwise, the temperature in the room will go on increasing and reach a point of suffocation or extreme dryness, disturbing the home atmosphere.

Effect on Oxygen Levels

Room heaters diffuse heat either in the air or directly on surfaces, at times when these levels are high the oxygen levels of the room get imbalanced and the room starts feeling suffocating. 

They also induce dryness, skin irritation, dry eyes, and nasal blockage. 

Therefore, one must properly check the effect of room heaters on oxygen levels before buying one. 

One example of a suitable room heater is an oil-based heater.


Portable room heaters are better to manage and easy to transport from one room to another. 

If the room heater is heavy and large in size, one cannot move it to other rooms when the need arises. 

This creates unnecessary inconvenience which should be avoided by choosing a room heater that is lightweight, easy to manage and transport from one room to another.


Most basic room heaters range around Rs 1000 – 2000. 

But if you are looking for additional and advanced features, the cost can be between Rs 5000-7000. 

The costliest room heaters are oil-based ones as they range around Rs 10,000 – 15,000. 

However, one cannot doubt the various high-end features they provide.

Cord Length

This is the most overlooked feature. 

And once the heater is purchased only then people notice that the cord length is not adequate. 

Although most room heaters for homes come with sufficiently long cord length, it’s better to have a look before making a purchase, to avoid any surprises.
