Choosing the Right Under Desk Heater

Best Under Desk Heater Buying GuideHere are some important things to consider when shopping around for your next under desk heater.

Heating Capacity

The first thing you got to check and determine is how much heating capacity is it that you actually need. Think of the area that you want to be heated, are you going to use it at home, your office, or somewhere else.

Take note that 10 watts of heating capacity should be good enough for a square foot. So naturally, 1500 watt heater should suffice for a good 150 square feet of space.

You don’t want to buy something that would be too hot, inconsistent, or has poor heating capacity for your place. Heat rises so if your place has a high ceiling then consider that too.


There are a few types of heaters that you can choose from, let’s discuss them briefly.

First up are convection heaters. Convection heaters are ideal for heating a room and for an extended period. As the name indicates it utilizes convection currents for heating air as well as circulating it.

Radiant heaters, on the other hand, are ideal for a room where people are within what you call the line of sight of the heater. You may also call it as spot heating. These type of heaters supplies heat directly to floor or wall panels.

Ceramic heaters are also very consistent and may provide heat on an area for long periods of time without any risk of it burning or posing any fire hazard. Infrared heaters work by emitting a precise beam of heat to warm you directly using a steady stream of heated particles.

Lastly, there are also micathermic heaters available. These are hybrid models that combine the best aspects of a radiant and convection heaters. They are extremely energy efficient and mostly provide 80% convection heat and 20% radiant heat.

So once again, think of the place you need to warm up and ask yourself which type of heater would be ideal for your setup.


Under desk heaters are meant to be small, compact, and ideal for tight spaces. That’s why they are also called personal heaters and they are meant to provide you heat in a focused manner.

They can vary in design as some of them can be situated on night-stands, the floor, or on top of your table. If you look hard enough then you’d probably find a model with a convenient footrest.

So this is the reason why most of them have a flat design. To accommodate you and the area it needs to heat.

Noise Levels

Just like your air conditioning, heaters also emit a little bit of noise. There are actually fanless varieties that are naturally more of a silent operator than its counterpart.

This would be super beneficial if you want a silent workplace and you don’t want that extra heater buzz to distract you. Micathermic heaters are almost noiseless so they are an ideal choice for these situations.


As if there’s any doubt that ensuring your safety is a top priority. As we all know, heaters can be burn or fire hazards. But because of the modern design of under desk heaters, it eliminates a lot of worries and is generally not prone to any safety issues.

One thing you need to be sure of is that you are buying a certified under desk heater. Ones that are certified by a known independent organization should be the safest. These are the ones who follow safety protocols and have features and components that won’t endanger you.

You have the ETL, UL or Underwriters Laboratory and CSA or Canadian Standards Association for example.

Some of the features that you should watch out for are cool-touch exteriors to prevent any burning, automatic shutoff timers to not let your unit overheat when left or not in use. Watch out for these features as they can be lifesavers.


Maybe not on top of your priority but if you’re someone who needs varying intensities of heating or if you have erratic weather conditions in your area thus needing different settings for heating then find out that does have multiple options for heating capacity.

Most heaters would have a low, medium, and high settings and would be ideal to keep you comfortable all day long.

A warranty should also be another aspect that you should inquire about before buying an under desk heater.
