Best Convection Heaters

Convection heaters work on a basic thermodynamics principle: convection. They make use of convection currents, which heat the air and circulate it throughout the room.

Comfortable heat is no doubt a necessity for homes across the globe. But while more and more new kinds of heaters are sprouting up here and there, one type of heater remains common among households: convection heaters.

Did you know that the first-ever heating systems in history made use of convection? Thousands-of-years-old furnaces were found in Greece and were discovered to operate through convection. From 2,500 BC up until today, the convection heater continues to be a reliable source of heat for people worldwide.

If you’re considering buying one or thinking if it is the best choice of heater for your home or business, then read on to find out all there is to know about convection heaters and the best convection heaters in the market.

What Are Convection Heaters

Before going deeper into the topic of the best convection heaters out there, it’s important to understand how convection heaters work, what their parts are—all of the basics. This way, you can make informed decisions when buying the best convection heater that suits both your needs and preferences.

How Do Convection Heaters Work?

Convection heaters work on a basic thermodynamics principle: convection. They make use of convection currents, which heat the air and circulate it throughout the room.

To put it simply, convection heaters operate on the fact that hot air is less dense than cold air. So hot air goes up, cold air goes down.

The process goes like this: cold airdrops, it comes in contact with the convection heater, the unit’s heating element heats it, and the heated air rises. This cycle of heat transfer goes on and on until the user turns off the heater.

Some convection heaters run on electricity, while others make use of fuel and oil. Their heating elements, meanwhile, come in different kinds, including resistance wire, metal coils, and ceramic heating element, among others.

Are convection Heaters Energy-Efficient?

The energy efficiency of a convection heater depends on how you use it. If you’re looking for a long-term heating solution, a convection heater is your best bet. But if you’re planning to heat spaces where drafts are often present, this type of heater might not be the most energy-efficient choice.

Convection heater owners understand that this kind of heater can take a long time to heat a given space. But when it does heat the entire room, users can enjoy evenly distributed heat throughout the day.

Generally speaking, convection heaters are energy-efficient when used for constant, long-term heating of enclosed spaces.

Are Convection Heaters Safe?

As with all other kinds of heaters, a convection heater is safe to use as long as you follow the safety tips. For instance, you have to keep combustible objects, like curtains, paper, clothing, and flammable liquids, at least 3 feet away from the heater. That way, you won’t have to worry about the risk of these objects igniting.

Another tip to prevent fire hazards is to make sure that there’s nothing blocking the airflow of the heater. When objects block the heater’s airflow, chances are the heated air will be trapped in the unit, thus causing it to overheat.

Before using your heater, you need to inspect it for broken cords or plugs or loose connections. If you spot any damaged electrical wires or components, avoid turning on your heater at all costs. Also, you should plug the heater directly into a wall outlet and avoid plugging it into the same outlet as that of other electrical devices.

Of course, you need to read the warnings and instructions on your manufacturer’s manual, especially if you’re just about to use your heater for the first time.

Most importantly, you have to check if your heater is certified by a recognized testing laboratory. Some of the certifications you can find on the labels of tested convection heaters are UL Listing, Intertek Certification, and ETL Listing.

Things to Consider When Choosing the Best Convection Heaters

Before getting a convection heater for your home, you have to consider what your heating needs are. You also might want to consider the convection heater’s type, size, features, and energy consumption. 

Types of Convection Heaters

Electric Convection Heaters

As the name suggests, electric convection heaters run on electric power. Plug the unit in the outlet, push the button, let it do its heating magic, and be comfortably warm in no time. Because of how convenient it is to use, an electric convection heater is the most commonly used type of convection heating across the world.

If you prefer convenience, safety, and good indoor air quality, then an electric convection heater is well worth the purchase. You have to keep in mind, however, that not all electric convection heaters are energy-efficient. That’s why you have to get energy-efficient convection heaters from trusted manufacturers. You also have to check their labels for UL ratings or other official certifications.  

There are different types of electric convection heaters:

Fan convection heater – is a heater that makes use of a fan to spread heat more evenly and rapidly. It is also ideal for small rooms. But the problem with this type of convection heater is that it operates with a bit of noise.

Panel convection heater – is a type of heater used for widespread supplemental heating. Most panel convection heaters are made to be easy to control, and they often come in sleek designs.

Oil convection heater – is a common type of heater for residential use. While it has an oil-filled reservoir, it runs on electricity and does not burn any oil. It’s ideal for long-term indoor heating.

Natural Gas Convection Heaters

Cheaper and more energy-saving, convection heaters that operate on gas are great when you want to cut down your electrical bills. Just fuel it up, and you can have comfortable heat throughout the room.

Gas convection heaters have gotten a bad rap over the years because of carbon monoxide poisoning incidents, gas leaks, and other hazards. Fortunately, modern gas convection heaters are now designed to be safe to use indoors and outdoors.

Like other heaters, you have to check if the gas convection heater you’re eyeing has been accredited by a national testing laboratory. You also have to follow the manufacturer’s manual and instructions to avoid any heater hazards.


The room size and the size of the heater might be an obvious factor when buying a convection heater, but it still needs to be mentioned. While convection heaters are designed to heat wide spaces, many HVAC brands have also built convection heaters specifically for those who want to heat small rooms.

Considering the room size is important for heating a space efficiently. For one square foot of your room, the heater should be able to deliver 10 watts of heat. 

If you need to heat a small room, then you might want to get a wall-mounted convection heater. That way, you won’t have to worry about sacrificing your floor space for your heating needs. But if you don’t have enough wall space, then a small portable convection heater can do the job just as well.


To ensure that the convection heater meets your needs, you have to check if it has the features that allow it to perform as optimally and efficiently as possible.

If you want your room to have evenly distributed heat, you might want to get a convection heater with a built-in fan. The downside of having a fan-forced convection heater is that it can generate noise, which can disrupt sleep.

But apart from this, some features that you might want your convection heater to have are a built-in thermostat, humidifier, and a filter. A thermostat lets you control and set the temperature easily, while a humidifier and filter can improve your indoor air quality, especially during winter.

Most importantly, you have to check if the convection heater you’re eyeing has safety features. Some safety features to look out for include tip-over switch, which shuts off a space heater when it gets accidentally knocked over, and a thermal cut-off function, which prevents the heater from overheating.

Final Thoughts

Convection heaters are great for eliminating drafts and heating large rooms for long periods. Compared to other types of heaters, convection heaters can be bought for a cheaper price, and they are more economical when used for long-term heating. And because their heating elements are not exposed, they are generally safe to use. 

Another great thing about convection heaters is that they don’t produce too much noise, making them perfect for bedrooms and living spaces. Moreover, since they transfer heat by convection, these heaters can distribute warmth evenly throughout the room.
