There’s nothing worse than being cold when trying to get work done. It may be sweater weather season, but if you find yourself still shivering while checking your emails, it’s time to turn up the heat — and a space heater is just what you need. If you work in an office, it saves you from begging your manager to raise the thermostat, and if you’re working from home, using the right one can lower your heating bill. There are many different types of space heaters, each ranging in size and price. However, if you want to save space and avoid clutter, tucking a small one beneath your workspace may be the way to go. Keep reading to learn our recommendations for the best under desk heater for you.

Fun fact: working at a comfortable temperature may help you get more work done. According to a study reported on by USA Today, cold offices make women less productive. And while one could certainly make the case for wearing your fashionable winter coat during your daily zoom calls, you’d probably prefer feeling warm. Completely understandable.

What to Consider When Looking for the Best Under Desk Heater for You

When searching options for a personal heater, your work situation is the first thing to consider. The size of a heater will depend on the height of your desk, if you share a space with others, and if so, how large it is. Access to outlets (more on that below) and power output are things to factor in.

Heaters with a high watt (anything above 1,000) will heat a larger room – about 10 by 15 feet – but they use more electricity. If you don’t want a spike in your electric bill, a heater with a lower watt can still be effective. There are ones that have an output as low as 150 watts that can still thaw your toes.

They’re surprising affordable. Although you’ll find some personal heaters in the triple-digit price range, there are an abundance that can be scored for under 50 bucks, most having extra safety features and control options.

Is it safe to put a heater under your desk?

Like any electrical appliance, an under desk heater has risks — and that’s why it’s important to pick a good one. The Consumer Product Safety Commission (CPSC) advices keeping flammable material three feet away from portable heaters. In plain English: Keep your papers on your desk, not on the floor. Make sure your heater has also been given the thumbs-up by a nationally recognized testing laboratory such as UL or Intertek. ( Their certification sometimes appears as “ETL”). To avoid causing a short circuit, under desk heaters should be plugged directly into a wall outlet. Avoid running extension cords beneath a rug. And of course, never leave a space heater turned on and unattended, or where it could get wet.

If some of these safety tips are making you think twice about getting an under desk heater, don’t worry. These appliances have come a long way since they were invented in 1905. In fact, to cut back on safety risks, many are made with flame retardant material and overheating protection.

Can I have a space heater in my office?

It depends on where you work, and your particular desk set-up. Although there are no federal workplace regulations that prohibit the use of personal heaters, you may want to ask your boss for permission. The same rules of safety apply whether working from home or an office building. Make sure to keep it away from your hard drive, as the additional heat can cause the hardware damage. If you’re not in a cubicle, you may want to place yours to the side of your desk instead of beneath your workstation.

If your workplace doesn’t allow space heaters, there are alternatives: Electric blankets, hand warmers, and even hot water bottles can make the atmosphere more comfortable.

What type of electric heater is most efficient?

You may think that if you’ve seen one portable heater, you’ve seen them all, but you’d be wrong. There are oil based heaters, infrared space heaters, panel electric heaters, and more. Most under desk space heaters fall into one of three categories: convection, radiant, or combination.

If you remember your Earth science class, you may remember what convection motion is. Warm air rises, while cooler air drops in the atmosphere, creating a type of current. Convection heaters work the same way. As air inside the heater warms up, it rises and draws cooler air towards the machine.

Although they take a while to get going, convection heaters are wonderful if you have your own enclosed office space. Many different portable electric heaters fall into this category, but if you want something that fits under a table, look for a ceramic or fan-based one. They’re smaller, tend to come with a built in thermostat, and are cool to the touch.

Radiant heaters utilize infrared rays. They won’t take the chill off an entire room, but they’ll warm whatever is directly in their path, making them ideal for under desk situations. They won’t dry out the air, and they warm up super fast.

Heaters that fall into the combination category have both a heater and fan. Like a convection space heater, combination space heaters can circulate warm air throughout a room. However, their energy can be focused on a single area — like your legs — and the fan can be used solo.

What is the most efficient stand-alone heater?

When it comes to choosing the most efficient stand-alone heater, it boils down to what’s important to you. If you’re concerned about your electric bill, choosing an under desk heater with a low energy output is your best bet. If you’re more interested in getting toasty ASAP, then a radiant or combination heater is the way to go. Regardless what type you opt for, we have plenty of choices to pick from below.
