What are Space Heaters?

Before we dive into the safety tips and ask questions it is very important to know about the product that we are talking about. Let’s have a look at what space heaters are and how they work.

A space heater is a small appliance that is becoming very popular among people all because of the comfort and performance that it delivers. It is used to regulate the warmth inside an enclosed area. You can enjoy the warmth on an extremely cold day if you have a space heater by your side. Space heaters are limited to certain areas according to their ability and they are still good for your use. Imagine having it in your bedroom or office.

Contrary to central heating, most of which is used to supply heat in all places connected to the workplace or your own house, space heaters only give enough heat to heat one room. Space heaters are energy efficient and they mainly use electricity or other fuels like propane or natural gases. The best thing about a space heater is that you won’t need any installation and they are also very portable so you can easily move to the rooms you want it to heat.

Also, you need to keep in mind that the space heater also consumes electricity which is not at all inexpensive so if you want to save money this is a good practice for all the appliances you use. Leaving a space heater on with no one present in the room can be costly and also a wastage of resources and energy.

They use electricity to work and great hazards might take place due to overheating or short-circuits.

If you have a child or pet at home and you leave the heater on while you are outside then they might try to touch it or get near it might cause horrible burns or injuries to your loved ones. Space heaters are also kept on the floor and they can be in contact with the carpet or any other nearby furniture or objects that are flammable that might cause fire issues.

Where to place Space heaters?

The most important factor for placing a space heater lies in its name itself. Space is what you need to keep in mind while placing a space heater.

You must make sure that there is at least a 1-meter radius from other objects and even more with such objects that are highly flammable. Such objects when we say highly flammable inside a house are curtains, bedsheets, blankets, rugs and we cannot miss out on carpets. You must make sure that you do not keep your space heater near such flammable objects to avoid any mishap.

You also need to keep a heater at least 3 feet away from humans or any other living creatures like dogs or cats. It is not good to place a heater near you as it will only be a factor contributing to discomfort and also there are chances that children or pets might come into contact with the heater. You can keep them in one corner of the room and away from windows.

Heaters tend to release carbon monoxide while they work overnight and therefore they are dangerous to leave on overnight and we have studied this earlier. Let’s look at the problems that carbon monoxide can create.

Carbon monoxide can enter your body through your nose while you inhale when you are sleeping. This gas is not good for your health. This gas is named a silent killer as it is capable of drying your sinuses out and also binds the hemoglobin that is present in your RBC. If a lot of carbon monoxide binds with hemoglobin the amount of oxygen binding to your RBC can decrease.

Overloading circuits found in most households are mostly standard and this might be the reason to trigger great power failures or even fire.


When it comes to the protection we cannot say that all heaters are safe. Not all heaters are equal ceramic heaters in terms of exterior protection and warmth output.

Some heaters can have extremely hot exteriors while they work. Heaters like bar heaters and paraffin heaters have such problems they are not good for children and pets.

A little carelessness will cost you a lot.

Fire Outbreaks

You won’t find space heaters that are equally designed in terms of shape and size. They are all different and have different characteristics too.

Some heaters are tall and they can easily tip over and this might result in a fall which can lead to potential fire problems. When they fall they can come into contact with objects inside your house that are flammable and this can create a fire and you won’t even know it when this fire gets big.

Property damages

Many uncertainties are related to heaters and therefore these things can cause you a lot.

Many possible property damages can occur if there is carelessness around heaters. Once a space heater malfunctions it can create a great problem. People think in such a way that putting items on a heater will get them warm-up or dry them quickly. Highly flammable items on space heaters can be dangerous and this might also cause fires. This might seem very good at the start but this might end up adversely.

Every year there are many cases of fire hazards happening due to a heating system so one should take care of such things if they want to prevent such happenings.

Important Safety Tips

It is critically important to check your smoke alarm batteries regularly. You can follow this practice once a month. You can do this by pressing the button and then listen for the beep.

This will ensure whether they are working properly or not. To make sure they work properly for a long time you need to make certain that you replace the batteries every 6 months and also the whole alarm safety system every ten years. If there is any false alarm you should never disconnect it as you might forget to reactivate it and it might be a problem later. To remember about all these things you can make a to-do list or also set reminders on your cell phone.

You must go with such heaters that have a heavy base and they aren’t very tall that they tip over or fall and cause a fire hazard. Find versions with a weighted base or shape, which is shorter and rounded than high and rectangular, to prevent getting the tip over your radiator. A broad base and uniformly spread weight will make it impossible for your heater to flashover and the heating system will not by mistake burn a rug or any other item in the vicinity.

Automatic shut off

Many heaters come with an automatic shutoff feature that turns the heater off when overheating takes place.

This feature helps in preventing overheating the heater and causing too many damages or hazards. Such a feature can also detect if the heater isn’t properly balanced and in such cases, it won’t allow the heater to turn on until the problems are dealt with.
