Best Infrared Heater for Large Room

What is an Infrared Heater

An infrared heater is a common type of heater used to provide supplemental heat in indoor spaces. Infrared heaters come in all shapes and sizes and can be used in different ways.

Some infrared heaters are used in the standalone mode, while others can be mounted on the walls. Large infrared heaters need to be positioned strategically on the floor in your room. Small infrared heaters can be placed on the top of desks or any other sturdy and flat surface where they are used.

How Do Infrared Heaters Work?

Infrared heaters work differently from other types of heaters, including oil-filled heaters. Whereas some heaters heat the air and then move it around the house to increase the ambient temperature, infrared heaters directly heat surfaces and objects in the room.

The heaters emit infrared radiation that is like what the sun dissipates. The infrared radiation is invisible to the eyes and can reach all the objects and surfaces within the heater’s vicinity.

When the objects and surfaces in the room get heated directly by the infrared radiation, their temperature rises. It is the heat from the items that, in turn, warms the air in the room.

Through this process, infrared heaters provide a convenient, rapid, and environmentally friendly method of heating small to large indoor spaces.

Benefits of Infrared Heaters

Infrared heaters are more beneficial than other heaters, which directly heat and move the air in the room. Here are notable benefits of using an infrared heater for supplemental heat in your home, office, or any other area.

  • Even heating. Infrared heaters directly warm surfaces in the area in which they are used. The heated surfaces then transfer the warmth to the ambient air in the room. As a result of this process, the temperature in the entire room rises steadily and evenly. The difference between the temperature at the ceiling and the floor in a room in which an infrared heater is used does not exceed 3 degrees.
  • Reduced need for using a humidifier. During winter, the indoor air may be arid. Such dry air may cause health problems as well as damage the wooden items in the home. Using oil-filled heaters reduces the amount of humidity in the air. However, infrared heaters do not reduce the level of relative humidity in the air.
  • Clean air. Heaters that have inbuilt blowers may contribute to the presence of small dirt particles in the air. The particles may spread with the hot air that is blown around the house. Using infrared heaters solves this problem because the heaters do not force air around the room.

Negative Effects of Infrared Heating

Although infrared radiation is not visible, it does have far-reaching adverse effects on the human body and the environment. Here are a few critical adverse effects of infrared radiation.

Damage to the Eyes

When you get exposed to the radiation for a long time, your eyes’ internal temperature rises considerably. The rise in the temperature may lead to cancers of the cornea and other parts of the eyes.

Also, repeated exposure to the radiation can cause cataracts, a form of eye disease which usually leads to blindness.

Effect on the Skin

When you expose your skin to infrared radiation for a long time, you risk developing skin burns. Skin burns occur when the temperature of the skin rises over 40 degrees Celsius repeatedly.

Skin burns may be a sign that you may create other severe conditions such as cancers. However, having skin burns does not necessarily mean that one is at risk of developing skin cancers.

Greenhouse Effect

The greenhouse effect occurs when the temperature of the earth rises considerably and consistently. This trend causes massive changes in climate and weather conditions over time. Increased infrared radiation in the atmosphere of the earth contributes to the consistent rise in the earth’s temperature.

What Size Infrared Heater Do you Need?

The size of an infrared heater refers to the space that the heater can effectively warm and not the physical space it can occupy. There is usually no relationship between the physical dimensions of a heater and its heating capacity.

Some heaters with compact designs can sufficiently warm large spaces. Conversely, some bulky heaters may be suitable for warming small areas only.

To determine the right size of an infrared heater that you should use, first determine the area of the region that needs to be warmed.

If it is just one room, then you need to calculate its area in square feet. The area of space is usually calculated by multiplying the length and width. You can measure this to be certain of the figures that you use.

If you have a square room that measures 20 feet by 20 feet, then the room area will be 400 square feet.

Once you have the room area in square feet, you need to convert this into BTUs. The heating capacity of heaters is usually indicated in terms of BTUs.

However, you will hardly find a BTU rating on infrared heaters. The only useful information that you will get on your heater is the wattage rating. Most infrared heaters are rated 1,500 watts.

Luckily, there is a relationship between watts and BTUs. Usually, to convert watts into BTUs, you only need to multiply your wattage figure by 3.413. Therefore, if your heater is rated 1,500W, it means that it produces about 5,112 BTUs.

A rule of thumb is that you need 10 watts to heat every square foot space in your home. Thus, your 1,500W-rated heater can comfortably heat a room that measures 150 square feet.

In other words, for your room that measures 400 square feet, you need a heater that is rated 4,000W or one which can produce 13,600BTUs.

However, in practice, many other factors can influence your determination of the heater’s size needed for warming your rooms. For example, if the place has a high ceiling, you will need additional BTUs to cater to the more space between the floor and the roof.

Factors to Consider When Choosing Your Infrared Heater

You need to be sure about the features you are looking for before deciding on the specific infrared heating model. All brands of infrared heaters have unique characteristics. The features influence their performance, mode of operation, and ease of use.

The following are a few factors that you should consider when buying an infrared heater.

  • Heaters may have any of the following modes of controls: manual, remote, or smart. Manual controls often comprise of knobs that are positioned on the front surface of the heaters. Some come with remote controls that help you manage your device from a distance. The most advanced brands are Wi-Fi-enabled. This means that you can use an app on the phone to control their operation.
  • Infrared heaters come in all manner of shapes, sizes, and colors. If you intend to either mount your heater on the wall or place it at a strategic position in your living room, consider its design. Go for heaters that have colors that blend with the interior décor style of your home. Also, choose heaters that can provide aesthetic value in your home because of their modern or contemporary design and sleek look.
  • Safety features. Some heaters have inbuilt safety features for maximum safety when in use. The two most common safety features that are found in heaters are overheat protection and tip-over protection. These features help to prevent the outbreaks of fires if the heater either overheats or falls, respectively. Other heaters are made of materials that are poor conductors of heat. The surfaces of such heaters remain cool even after they operate for a long time.
  • Infrared heaters are designed to provide additional heating in homes. They are usually used to warm one room at any time. Therefore, you may have to move your heater from one place to another where it is needed at any given time. Go for heaters that are highly portable because they have handles and caster wheels.

Safety Tips When Using Infrared Heaters

Infrared heaters, like any other electrical device in your home, pose a considerable level of danger. The most common risks associated with using infrared heaters include fire outbreaks and shocks. Occasionally, a heater may cause burns to kids or pets.

Follow the following tips to minimize the risks of using these devices and prevent the occurrence of accidents.

  • Plug your heater directly into the wall. Avoid using extension cables because it is not easy to find a cable that can handle your infrared heater’s wattage needs. If you connect your heater to an extension cable, then your device is likely to malfunction. The cable may also heat up and cause fires because it is unable to cope with your device’s needs.
  • Conduct routine maintenance and checks. Regularly check your infrared heater to ensure that it is in good shape. If you detect any problem, ensure that you talk to a technician to help you fix it.
  • Keep the heater away from water. If your infrared heater is not designed to be used in the bathroom, ensure that it does not contact water. Using your infrared heater under damp conditions may cause electric shocks.
  • Keep combustible materials away from your infrared heater. Flammable materials in the home include clothing, bedding, drapery, papers, and plastics. Ensure that such materials are at least 3 feet away from your infrared heaters to prevent fire outbreaks.
  • Switch off your heater when it is not in use. It is always good to switch off your heater and unplug it when it is not in use. Ensure that you do this even when you are leaving the house briefly. Heaters should not be left unattended because of the risk that they pose to everyone at home or anywhere else where they are used.

Do infrared Heaters Use a Lot of Electricity?

Infrared heaters do not use a lot of electricity. Most electric infrared heaters are rated 1,500W. This rating means that they draw 1.5kW of power for every hour when they are in operation.

Also, the heaters draw in about 12.5A of electric current. If you place such a heater in the same circuit with other devices that draw a lot of electric currents, then the entire circuit may trip. This is because standard domestic circuits contain 15A of electric current.

Electric infrared heaters do not consume a lot of electricity because of their settings. They usually contain multiple heat settings, including low, high, and eco-modes.

When set on the low mode, a 1,500W-rated heater will require only 750W. However, its heating capacity diminishes considerably when it is put on the low heat mode.

Can you Leave Infrared Heaters On All the Time?

Although it is practically possible to leave your heater on all the time, it is not wise to do so. Infrared heaters are supposed to be used as supplemental sources of heat and not the home’s primary source of heat.

You need to use them only when there is a need to create additional warmth in the house. The need for extra warmth is usually experienced in specific rooms in the home occupied by people at any given time.

Leaving your heater to run 24/7 is unnecessary because it will increase your heating costs. Furthermore, if you leave your heater to run all the time, it means that you will let it run at night when everyone is asleep or at a time when there is no one at home.

Remember that infrared heaters should not be left unattended. Thus, it is not a good idea to run your heater all the time.
