  • Design: Personal heaters come in ceramic (convection), infrared (radiation), and micathermic (hybrid) models. 
  • Size: Most mini desk heaters are smaller in size since they’re built for tight office spaces. In effect, they’re more portable than regular heaters!
  • Energy: As a result of being compact, these devices are more energy-efficient, yielding a power output between 100-1,500 Watts. 

In essence, these appliances come in various shapes and sizes and are similarly packed with many, unique features. Sifting through the market, here are some of the best under-desk heaters I’ve found that can be purchased online!

FAQs about under-desk heaters

What’s the difference between a heater and a space heater?

A “heater” is a broad term, referring to the different equipment used to warm up your surroundings. Central heating systems are the most popular type, being primarily powered by gas or electricity to distribute heat. 

They’re typically found in households; You’ll probably recognize these as boilers, furnaces, or heat pumps. 

On the other hand, space heaters are the subset of smaller devices, which contain electricity or combustion mechanisms to produce hot air. The key difference is that, instead of using transfer ducts, their equipment is compact and portable!

Personal heaters can be gas-powered or electric—the latter being more common nowadays, as they only require a wall socket to function.

How do you choose the best under-desk heaters?

When choosing a personal heater for the office, it’s important that you value your safety as much as your equipment’s functionality. For what it’s worth you wouldn’t want your device to tip over or overheat!


Here are some hazards you should keep in mind when making your purchase:

  • Overheating: The most notorious risk factor, heaters can start fires if you aren’t careful enough. For your protection, get a device with automatic shut-off features.
  • Tilting: Some appliances are hot to the touch—and tipping your heater only increases the danger! However, if your device has a tip-off switch, it will automatically shut down at the slightest nudge. 


To maximize your heater’s utility, you’d want to get a device that is both compact and energy-efficient. In selecting a model, consider the following factors: 

  • Size: Provided that you’re keeping these under your desk, make sure to measure the space it’ll occupy. Consider your proximity to power outlets, as well as your workplace accommodations. 
  • Wattage: The general rule of thumb is that, the larger the heater, the more heat it produces—but the more energy it consumes! In this case, you must decide between two options: A heater that covers more space, or a heater that’s easier on your electric bill. (If you’re lucky, you’ll find some models that meet in the middle!) 
  • Degree of Oscillation: Heaters with good oscillating features can cover larger areas.
  • Added Features: Viewing the list above, some devices come with extra tools—such as built-in handles or digital interfaces—to further enhance your experience.

Is it safe to put a space heater under the desk?

As the name suggests, space heaters are meant for office use—so yes, it’s generally safe to place them under your desk. In fact, most models are designed for flat surfaces and should be non-flammable. 

However, since you’re dealing with heat, it’s always best to practice caution. To care for yourself and your appliance, take note of these safety guidelines:

  • To avoid tipping, place your device on a flat surface.
  • Keep away from flammable materials, such as cloth, paper, wood, and gasoline. 
  • Position ceramic space heaters at a 2-3 inch distance from walls. 
  • For added protection, keep yourself and other objects (eg. furniture, curtains, and upholstery) three feet away from the appliance. Always supervise kids and pets. 
  • To prevent burns, avoid touching your heater (especially the metal grid). If the surface gets too hot, don’t use it—dispose or return instead.
  • Be it at home or at work, never leave your device unattended. When not in use, it’s best to turn it off.

Are under-desk space heaters a fire hazard?

It’s generally safe to use space heaters under desks. However, cases of overheating, tipping-over, and burns are certainly risks to be concerned with.

Fortunately, with the right amount of caution, you can easily prevent fire hazards! Here are some quick tips:

  • Before use, be sure to check its plugs, wires, and cords.
  • Always directly connect to power outlets. Using an extension cord might melt your plug. 
  • Monitor your heater’s temperature settings.
  • Keep away from flammable objects. 
  • And again, most importantly: Never leave your device unsupervised. 

How can I clean my under-desk heater? 

Luckily, there isn’t much to it! To quickly remove dust, simply wipe its front
and back sides using a damp cloth. If the dirt is particularly stubborn, use a blow dryer (with a narrow nozzle) to blow-away remnants.
