How Do You Heat a Cubicle?


One challenge people might face is the area they have to work in. Cubicles are tight as can be. In general, they're working in an area of 25 square feet. 

So, a radiant heater won't be suitable for this situation. We have to go smaller in our choice of heaters. In most cases, the area is also open. Thus, it can add difficulty to the job of heating. 

In this situation, you don't need to look for a heater that's capable of heating an entire room. Instead, look for one that's effective in warming a person or small area. 

The heaters that fit this scope are ceramic, infrared, and forced air heaters. You can go with ceramic if you're more safety oriented. Infrared is a good choice if you want to keep it out of sight. 

For warm air circulation, forced air heaters are the ones you should consider. Let's take a look at some of them!

1. NUMIFUN 2-Pack 500W Electric Personal Heater

In an enclosed area like a cubicle, you need to focus on specific parts of your body. So, if you want to maximize the heating potential, consider focusing on your feet and hands. And what better way to do that than with multiple small-sized ceramic heaters!

The one above has a rating of 500 watts. So, if your outlet can handle it, you can run one under your desk and one on top to target your hands. It also has an adjustable thermostat and auto-shutoff features. 

If you're limited in space, these could be a worthwhile look.

2. NUMIFUN Infrared Space Heater

If direct heating is what you want, look no further than an infrared heater. They're typically used under an office desk. Thus, it could be an effective way to keep warm in a cold cubicle environment. 

The infrared heater above is a good choice if you like simplicity. It does feature a thermostat, but it only has two settings. Additionally, it also has tip over and overheating protection. 

For wattage rating, it needs 500 watts to operate. So, it should be safe to use without the worry of overloading a circuit in most cases.

3. WAPEMORK Bladeless Heater Fan

Last but not least, you can always resort to using a fan heater. They're a good choice for circulation. However, they'll generally use more power than the other options. With a rating of 1,500 watts, it could be a problem in a cubicle. 

Still, it's worth considering. The heater above has an ETL certification. It also includes multiple safety features. The only problem with using this depends on where you plan to place it. If it's under a desk, it should work. But depending on the desk space, it might be too big.

How Do You Warm Up An Office Space?

The second area we'll cover is an office. In this situation, you have an entire area or room to yourself, so you don't have to worry about others around you. 

In most cases, you'll need a heater that's powerful enough to heat the entire room, and you'll probably want to maintain that heat as long as you're working in the area. For this reason, you should consider looking at an oil-filled radiant heater. 

As some users suggest, they're the best for long durations of heating. They're also one of the safer options. However, it does take a little longer to heat the room. The reason is that oil takes time to heat up.

4. De'Longhi Full Room Radiant Heater

The De'Longhi radiant heater above has a wattage rating of 1,500. Multiply that by 3.41, and it will tell us that this heater has around a 5,115 BTU rating. 

Office space will usually be around 100 to 175 square feet. Thus, this oil-filled radiant heater will work in most cases. Aside from that, this heater has safety features like a thermal shutoff. This way, it shuts off when it overheats.

Temperatures are also adjustable for your liking. As for construction, it uses a metal body.

Users also report that it stays relatively quiet during operation. However, it will occasionally make a noticeable sound. If you have a large office space, this could be worth considering.

What To Consider

If you aren't pleased with the choices above, you'll have to keep looking for options. Of course, you shouldn't pick a random heater. Let's go over some factors that will matter in your decision.

In general, the three main factors that make a great heater are size, safety, and heating capacity. An honorable mention would be noise level, though some people might be able to tolerate the noise heaters can make. So, that part is a matter of personal preference. 

Let's go over why these factors matter!


Some people have fears about using a space heater. And they have good reasons to fear it! 

It comes as no surprise that space heaters can be potential fire hazards. They're high-wattage appliances that can spark a fire in a couple of ways. The first way would be through a blockage. 

If you block the exhaust with items like curtains, beds, sofas, paper, clothing, or flammable liquids, it can ignite, causing a fire. The second way it can start a fire is through its wire. 

Heaters require a lot of power, and sometimes, the wall outlet might not be able to handle it. The same thought process goes with using extension cords or power strips. If it can't handle the heater's needs, you're putting yourself at a higher risk of starting a fire. 

For the reasons above, look for heaters that include safety features. Some heaters, like ceramic heaters, will have automatic shutoffs. So when it overheats or tips over, the appliance will shut off automatically. 

Others will also have cool-touch housing. Thus, the casing won't burn you if you touch it. 

Lastly, make sure you look for one of these certifications:

  • UL (Underwriters Laboratories)
  • ETL (Intertek)
  • CSA (Canadian Standards Association)


The size of the heater also matters. It all depends on your needs. Some people will have an entire office that needs supplemental heating. Others might not have the same luxury. 

Working in cubicles means you're going to have to consider coworkers. In this case, a small portable heater that can provide warmth for 1-2 people would work best. 

To maximize the efficiency and coverage a space heater can provide, you can use a simple formula. You'll need to find the wattage necessary to heat your office. Multiply that number by 3.41 to get the BTU rating you need in a heater. 

For example, if your office or cubicle has an area of 50 square feet, it would need a 500-watt heater. Multiply 500 by 3.41, and it shows you need a 1,705 BTU rating to heat the space adequately. 

Can You Put a Heater on a Desk?

In general, there should be no problem with putting a heater on a desk. However, it's essential to consider the items on top. If you're working with a lot of paper, it would be better to place the heater on the floor. 

Experts recommend keeping heaters 3 feet away from anything that can burn. And if you must place it on a desk, make sure it is flat and level. Place it in an area where tipping it over is avoidable. 

Can a Desk Heater Heat a Room?

Sometimes desk heaters can use a good amount of power. It raises the question—can a desk heater heat a room? It depends on the wattage.

Some desk heaters can use up to 1,500 watts. As mentioned, those types of heaters are enough to heat a 175 square foot room. As the wattage lowers, it will be less capable of accomplishing this job.
