Buying Guide: Choosing The Safest Space Heater

How Do Space Heaters Work

You’ll find many types of heaters in the market today, but not all of them are safe. To find out how safe the heater of choice will be, you need to understand how different types of heaters work.

1. Convection Heaters

These types of electric heaters for home work by circulating convection currents across a resistor/heating element, such as such as oil, an electric coil, or an electrical wire. The resistor converts this convection current into heat energy. This hot air moves throughout the heater body and the surrounding space. It continues to increases in the area until the whole room is heated evenly.

The most popular types of convection heaters are oil-filled radiators and ceramic heaters. Other types of convection heaters utilize a fan to increase the distribution of heat within the room.

If you are looking to use a convection heater, choose ceramic plate units as they tend to be the most efficient heaters for long-term whole room heating.

2. Infrared Heaters

Infrared heaters produce the natural and same type of heat that is very similar to the sun. Unlike convection heaters, infrared units don’t warm up the air. They emit rays forward towards the items in front of them. The object then absorbs the heat and transfers it to the surrounding space.

The advantage of using infrared space heaters is that they don’t dry the air like convection heaters. They are recommended for people with sensitive skin. Also, they are the most energy efficient space heaters.

The downside is that they are expensive and suitable for only small spaces. That means you can’t use them to heat an entire room.

3. Oil-Filled Heaters

Aside from being one of the most popular space heaters used in various homes, oil filled heaters are reliable, energy efficient and safe. Also known as radiators, these heaters consist of a series of joined columns or fins that are filled with oil.

These heaters are powered by electricity, and the oil only serves as a heat reservoir. That means it never gets used up and you don’t have to worry about refilling it. Once the electric currents heat the oil inside the heater, it emits warmth through radiant heating.

4. Micathermic Heaters

Micathermic heaters use a completely different heating method than other heaters. For this reason, they can warm a large space much faster and efficiently. Moreover, they are safe to use.

Micathermic heaters combine both convective and radiant heat. However, they lack a blower. They have a unique and powerful heating element than the one used in regular convection heaters.

Safety Features To Consider When Purchasing A Space Heater

choosing a space heaterWhen shopping for a space heater for your home, you need to be aware of all the safety features it must have. Some heaters might work efficiently but lack these features. Others might be less-efficient as you’d like them to be, but they might have these features. So, it is important that you prioritize what you really need. If you have kids, pets, or many people in your house, then their safety must come first before you start using the heater.

Here are some of the safety features you should look for when selecting a space heater.

Tip Over Protection: To significantly reduce the risk of your child or pet getting burnt, you need to consider space heater models that have an internal switch that is programmed to automatically shuts off the power if the heater is accidentally tipped over or knocked down.

Automatic Shut-off/overheat protection: This is another vital safety function that will shut down the unit when it senses that the internal component reaches an unsafe temperature. This feature is mostly common in space space heaters with thermostat.

Cool-to-the-touch surfaces: Choose heaters that remain cool to the touch to protect those precious, yet curious, little hands that love to explore.

Other Features You Should Consider

Heating capacity:

The size of the room determines the heater wattage rating that you need. Most space heaters use 1,500 watts of power, and this should be enough to cover an averagely sized room as large as 150 square feet. However, this guideline is a general rule of thumb that doesn’t apply to every model. Depending on the heating technology, your indoor environment, and the application, some portable heaters may cover more space. I your room is about 500 to 1000 square, you can skip this section and visit our review for the best space heaters for 500 to 1000 square feet rooms.


If you select a space heater with a timer, you’ll able to set the amount of time you want it to run. This function turns off the device automatically after a preset number of hours, making the unit energy efficient, so you don’t waste energy by running the heater when you don’t need it.


Most space heaters have a thermostat that lets you set the room temperature according to the time of day and day of the week. This gives you the much-needed flexibility to save energy and avoid waking up to a freezing house. Unlike most cheap space heaters, digital units have two or more thermostat settings that allow you to choose your desired temperature, and once the set temperature is reached, that temperature is maintained throughout the day or night.

Remote control:

Some space heaters have inbuilt buttons that enables you to control different features. However, remote controls have all the functions at one place, allowing you to control the unit at the comfort of your seat, bed or anywhere within the room.

Energy efficiency:

First, space heaters should only be used as a supplementary source of heat. Additionally, if you really want to conserve energy and maintain low heating cost, compare the efficiency of various units before choosing a space heater. Choose the right energy efficient space heater that is perfectly sized for your room. If you want to reduce your heating cost further, choose a space heater with special features such as energy saving modes, adjustable thermostats, low wattage, and programmable timers that help minimize power usage and contribute to economical operation.

Noise level:

It’s not fun to have the safest space heater that is noisy. All space heaters emit some noise during operation. However, the level of noise depends on the type of heater. Some models produce more sound than others. Non-fan forced units such as baseboard heaters and oil-filled radiators are considered some of the quietest heaters on the market – they excel at whole-room heating with little noise interruption.

Power cord:

Using a space heater with an extension cord is the worst thing you can ever do. Simply put, avoid it. What you need is a unit with a long power cord that gives you flexibility on where to position it. That way you can keep your heater away from flammable items.

Electronic display:

Most high-end models have a LED display that shows you the temperature reading of your house at that particular time. That way, you can reduce or increase the heat circulated depending on how you feel. Remember always to cover the display if you use the heater in your bedroom at night as the light can hinder your sleep.

Carry handle:

You might want to use your space heater in another room, and so you’ll have to carry it. If that’s the case, you’ll want to consider a heater with an inbuilt-carry handle.

Instruction manual:

Some heaters come assembled while others need to be installed in different positions of your room. Also, you might not be aware of all the safety instructions. That’s when you should review the instruction manual before actually using the heater.

Space Heater Safety Tips

As mentioned earlier, heating equipment is the leading cause of house fires, according to the National Fire Protection Association. These fires claim hundreds of lives, thousands of injuries and millions of dollars in property damage.

For that reason, safety should always be a top consideration, and you need to be very cautious with your space heater. Before you start using it, read the instruction manual so you can have a good understanding of the basic safety rules. Remember, all these heaters are made to be as safe as possible, but they are still heating equipment that produce a lot of heat, and if not used properly can cause fires.

Here are some tips to keep your home warm and safe at the same time when it’s cold outside:

Space Heaters FAQ

In this section, we’ll answer some of the common questions you might have about using space heaters as well as some safety tips.

Are space heaters safe?

Space heaters are made to be as safe as possible. However, that safety depends on the user and how yuo’ll are using it. If you use the heater as instructed by the manufacturer, then there is no need to worry. The problem arises when you ignore all the safety instructions and use the heater in an unsafe manner. Also, if you choose a heater that hasn’t been verified by a product safety organization.

Safe space heaters must have the label showing that a renowned testing laboratory recognizes it. If you’re in the U.S., you’ll see a UL or ETL label. If you’re in Canada, you’ll see a CSA or ULC label. These labels indicate that a testing laboratory has assessed and verified that the space heater’s construction and performance meet safety standards.

If you buy a space heater that has one of these labels and also the automatic shut off feature, then you’ll be heating your home without any risk of fires.

Can space heaters catch fire?

Space heaters can catch fire, which explains why they contribute a huge percentage of house fires that occur worldwide. They are responsible for over 40% of home heating fires and 85% of related deaths. Space heater fires are avoidable if you use them the right way.

Follow these tips to reduce the risk of house fires caused by space heaters.

  • Always inspect your heater before use to make sure it doesn’t have cracked or broken plugs or loose connection. Frayed, worn or damaged wiring should be replaced before using the heater.
  • Make sure your space heater power cord is in excellent condition. Plug it directly into the wall outlet and never on an extension cord or power strip. When space is operating, don’t use the same outlet for another electrical device.
  • Place space heaters on level, flat surfaces and at least 3 feet away from flammable items, such as furniture, carpet, clothing, cabinets, tables, etc.
  • Position the heater where it won’t be tipped over by people walking around the room.
  • Never leave a space heater on in an unattended room. Turn it off when you’re leaving the room or going to sleep. Children and pets shouldn’t play too close to the space heater.
  • Always unplug and safely store the heater when it is not in use.

Will using a space heater lower my heating bills?

Space heaters are supplemental heating appliances that should be used for small rooms. Since they are not designed to be your primary heating source, you can save energy if you use them the right way. If you try to warm every room in your house using a space heater, not only will it be inefficient but also cost you a lot more in the long run. The amount of energy you can save also depends on other factors such as the size of your room, the thermostat setting, and the number of hours the heater runs per day. Here is a guide about how much electricity a heater uses a day.

Are space heaters energy-efficient?

Some space heater models are marketed as energy-efficient. These types of models claim that they can help you save money while operating in the same manner as less-energy efficient models.

One important factor you should keep in mind when choosing a space heater is the size of the room you want to heat. If you’re going to warm one, small room, then a space heater will consume less energy than a central heating system.

For such type of room (one small room), choose radiant heaters, which emits infrared radiation that heats items that is closest to them. For whole room heating, it is wise to go for convection heaters which warms up the surrounding air.

When it comes to models, make sure you get the right kind. Some heaters are meant to heat large spaces and have a high wattage rating. Others are intended for small rooms and have a low wattage rating. Only choose one that is perfect for the room size you want to warm.

Do space heaters cause carbon monoxide?

Electric space heaters do not pose a carbon monoxide risk. They don’t use fuel, so there is no way they “react” with air to produce carbon monoxide. CO is only emitted by devices that burn fuel such as kerosene heaters.

Is it safe to leave a space heater unattended?

Even though your space heater has all the safety features, it is not a reason to leave it on in a room unattended. If you have kids or pets, it is even more dangerous to leave the space heater unattended as they can knock it down or bring flammable items close to it. If you want to go out, turn off the heater or warm the room later.

Is it safe to leave a space heater on all night?

can you leave space heaters on all night?This is a common question because many people feel they can leave the space heater on and the auto shut off will do its magic when they are asleep. The simple answer is, it’s not safe to leave a space heater on while you sleep. What if you have frayed, worn or damaged plugs or loose connections that you might not be aware of? These things could heat up and cause a fire.

Additionally, you are unconscious when you sleep, so it’s only reasonable to say that the heater is unattended. In that case, if the heater were to catch fire, you won’t be able to prevent or take control of the whole situation on time.

The best thing to do is to warm your bedroom 2 hours before you sleep. The heat circulated in the room should be enough to keep warm throughout the night. You can also use heavy blankets and warm clothes to keep yourself warm.

Besides, high room temperature isn’t right for quality sleep. For an ideal night’s sleep, your body temperature must decrease to initiate sleep. To help your body achieve this, you need a relatively cooler room than your body temperature. Setting the thermostat too high is only going to make you restless and affects the quality of REM (rapid eye movement) sleep, the stage in which you dream.

Note that, this is only a general rule of thumb. Not everybody will feel comfortable sleeping at the recommended bedroom temperature, which is between 60 and 67 degrees Fahrenheit. If you think you need to warm your bedroom, do it before you sleep, and it will be much easier to close your eyes for the night.

Where’s the best place to put a heater to warm up your house?

Where you position your space heater depends on what you want to achieve. The ideal thing to do is always to place the unit in the room where you want to heat. If heating a room upstairs is your priority, then it’s only wise to take the device upstairs. However, heating a whole room (both upstairs and downstairs) is a little different. You need to place the heater downstairs. At that room, the warm heat will rise and flow to the upstairs, displacing the cold air that is in there. Since cold air is denser, it will fall downstairs.

As much as safety is concerned, it is vital that you place your heater away from flammable items such as furniture, curtains, cabinets, carpets, etc.

For best results, make sure you’re at least 3 feet away from the heater. This way, you’ll feel the warmth without overheating.
