Room heaters are used extensively to beat the bitter chill in winters. Room heaters are efficient in heating up the interior of buildings. The easily available and affordable equipment can heat up a room within a few minutes. Their small and compact size allows them to be fitted in any space with ease. So, it’s no surprise that more and more people install a room heater in their homes. Although they are an easy and convenient way to keep warm, using room heaters is not recommended, even in the bitter cold. Read on to find out why using room heaters may be doing more harm than good in your home.

1. Fire Hazard

Fire Hazard

Room heaters are higher risks of causing fire accidents. Many fire accidents are reported every year solely due to improper use of room heaters. They should never be left unattended, use it only if you are present in the room. This is because most accidents occur when the room heater is covered. They catch fire instantly when they are covered. It is advisable to not leave them on when your sleeping, as there is a risk of it accidentally coming in contact with inflammable materials. The heater’s surface can get very hot and can be very dangerous to children, who might accidentally touch it while playing. The best option is to choose a room heater with thermostats so you have control over the temperature. Consider buying a timer-based room heater so that they automatically switch off after a while.

2. Oxygen Decreases

Oxygen Decreases

Fan based room heaters and halogen room heaters cause oxygen to be rapidly burnt and humidity in the air is significantly reduced. The depletion of oxygen leads to suffocation. 

Apart from these, the reduced humidity leads to dry eyes, skin, and nasal blockages. Using oil-based filters in your room heaters can prevent low oxygen and humidity levels as oil room heaters do not affect these. Room heaters are also quite noisy, this leads to disturbed sleep.

3. Increased Toxic Levels

There are two kinds of room heaters that are available in the market, unvented and vent-free heaters. The vent-free heaters have an in-built chimney that aids in ventilation and keeps the room cleaner by initiating a periodic fresh flow of air. Unvented heaters are more likely to release pollutants like carbon monoxide, in the house, which leads to brain and organ damage in infants when exposed to the whole night. Increased pollutants in a closed room aren’t good for adults too as it poses a threat to asthma and could also cause other respiratory disorders.

4. Temperature Fluctuations

Temperature Fluctuations

When you keep your heater at higher temperatures, it could result in temperature fluctuations when you walk in and out of the room. This is because your body might take time to adjust to the extremely different temperature outside and inside the room. The fluctuating temperature makes it difficult for the immune system to cope and could lead to fevers and illnesses. In the case of babies, overheating can sometimes lead to a condition called hyperthermia, which could be fatal.

5. Natural Moisture is Depleted

The most common problem of using a room heater is that the natural moisture in the air is depleted. The air sent out through the heater or the blower dries up natural moisture in the air. This dry air causes dry and rough skin. If your skin is sensitive, you may experience itching and redness that may lead to skin infections and rashes. Moreover, if a baby is exposed to this dry air, it could be more damaging to a baby’s sensitive skin and nasal passage. Extreme dryness in infants and babies caused by overusing a heater leads to skin rashes and nose bleeds.

Correct Usage of Room Heaters

 Correct Usage of Room Heaters

Make sure a bowl of water is placed in the corner of your room while the heater is switched on. This works like a vaporizer and keeps the moisture levels in the room intact. Make sure the heater is always kept at a reasonable temperature so the room is not overheated. Check your user manual and follow the instructions correctly and set the temperature as advised in it. Check and service your room heater by authorized service centers at least twice a year. 

This ensures that the tubes, coils and the bands are functioning efficiently and they don’t emit carbon monoxide into the room. Keep doors and windows of your room slightly open to provide natural ventilation. This way, you can get rid of pollutants and keep the room clean. Dress in warmer clothes, wear warm socks and gloves to bed to warm up so that you don’t depend on a heater solely. This allows your body to adjust to the cold season and your immune system begins to work accordingly and saves you from catching colds and flu.

Make sure you install the room-heater out of reach from the elderly and children.


Room heaters are a great way to warm up quickly, especially in places with extreme climates. However, there are quite a few pressing issues to consider related to safety and health while using them. Room heaters are good for limited usage in specific circumstances when used carefully. Most of the problems room heaters cause occur only when they’re used too much or improperly. But remember that a cooler room is better for achieving deeper sleep, the ideal temperature is 20-25°C. So, it’s better to consider the pros and cons of room heaters before installing one in your home.
