Keeping Warm While at the Desk  

On cold days a low temperature at your workplace could prove counterproductive. Even on warm days you might need to tackle a frigid climate inside the office. Women in particular can feel the effects - in general they have a lower metabolism rate, so they typically need higher temperatures to feel comfortable.

Offices are often on the cool side. Besides providing comfort for people, this is because of the use of computers and servers. These machines need to operate in colder temperatures for their best performance.

Unfortunately, maintenance teams do not increase the temperature to beat the chill. Not all systems are designed well; heating the building is expensive; and many other factors may mean the building or floor is too cold for your taste.

Space heaters that fit under or near the desk can literally be tucked away or placed out of the way in a corner of your cubicle. These electric heaters are small and energy-efficient so you won’t have to worry about a substantially higher electric bill. They are also safe because they don't emit any chemicals or gases and come with a cool surface.

What to Look For?

Heaters come in different sizes and shapes. Specifically, under-desk heaters are compact and typically one-tenth the size of a standard electric space heater. Because of their size they are more energy-efficient.

It’s important to evaluate them based on energy efficiency, features and safety parameters. You can use the following points to help you make a decision to buy one.

Heating capacity

Approximately 10 watts of heating power is needed for every square foot. This means you can expect a 1500 watt heater to be enough for a 150 sq feet space. Of course heat rises, so high ceilings might mean you need a more powerful unit. The same is true if you’re in a particularly drafty part of the home or office.

Noise Levels

Most heaters with fans are noisier than those without fans. Fanless heaters operate nearly silently. Micathermic heaters are the quietest heaters of all.

Type of Heater

For under-desk heaters, you’ll have several options for type of heating, including both convection and radiant heaters. Ceramic and infrared models are among the choices.

Convection heaters include ceramic heaters. Radiant heaters are good for spot heating. Infrared space heaters are radiant heaters that use infrared quartz bulbs as heating agents.

Micathermic heaters are a hybrid models that combine the best of both convection and radiant heating technology.


Personal heaters heat small spaces in a focused manner and are meant for tighter spaces. Some under-desk heaters  can be placed on a night stand, table or floor. Some even have an ergonomic footrest!


When considering price, don’t just look at the price tag. The efficiency, durability and warranty coverage also add to the relative value.


Of course it’s always important to stay safe. Be sure to check that your heater is certified by an independent organization as being safe.

Recognized testing laboratories such as UL (Underwriters Laboratory) or CSA (Canadian Standards Association) will mark a product as safe only if its construction and performance meet voluntary national safety standards.

Under-desk heaters are usually electrical appliances so they carry less risk than heaters that use fuel like kerosene. Still, a few precautions and policies can help avoid injury to yourself or damage to your home or office.

  • Keep them away from flammable liquids or any combustible material.
  • Use only heaters certified by national bodies like UL.
  • Make sure all cords and plugs are intact

  • Pick heaters with features like a cool surface, auto-shutoff mode and tip-over shutoff
  • Ensure that it is turned off when not in use.
