The Best 120v Electric Garage Heaters

Looking for a heater to keep your garage or shop warm? There are tons of different 120v electric garage heaters out there, and it can be overwhelming to weigh the pros and cons of each in a sea of options. 120v heaters can be ceiling-mounted or are offered in a basic standing design.

Understanding the voltage and heat distribution you need for your specific garage is key for finding a heater to get the job done right. We’ll take it from there and discuss the pros and cons of quality space heaters to help you pick the right heater for your garage.

Is 120v Enough for my Garage?

120v is a fairly small sized heater, but will absolutely get the job done for a smaller space. If you have a garage larger than 30 x 30 feet or a bigger garage that is not well insulated, you may need something with a higher voltage to keep it at a comfortable temperature in winter months. A 220 volt is really designed for commercial spaces, so, if you are trying to heat a medium-sized space it may be worth investing in two 120v heaters.

120/110 volt power outlets can take on between 15-20 Amps before the power breaker is affected. Check to see if your garage has a single breaker managing all of your lights and outlets or two or more breakers managing different outlets and lights separately.

Specs: 120v, 1500 Watts, 5120 BTU, 6ft cord, Infrared

This heater is not only designed for garages and workshops, but is also great for covered patios or decks. It can save up to 30%-40% on electricity when compared to traditional heaters. You may just get a great return on your investment with the Vesonel. The Versonel is much more effective in a closed in garage or shop. Those who used it outdoors did complain that without sitting within a 3-foot radius of the heater, it was difficult to really feel its effects.

  • Saves on electricity

  • 10,000-hour life span

  • Produces no odors, chemicals, or fumes

  • Reflective heating technology replicates warmth from the sun

3. TPI Corporation OCH46

TPI heater

Specs: 120v, 1500 Watts, hard-wired, radiant

This ceiling mount unit offers 1500 watts of heating, which makes it great for smaller spaces. You can go for that old-fashioned workshop look, as it includes two chains to hang it with; or you can mount it with included brackets that provide a 45-degree swivel range.

This is a radiant heater, so there’s no fan. But it provides consistent heat from ceiling to floor.


  • Consistent heat in its range

  • No need to worry about fan power

  • Provides good output in its limited range

  • Ideal for over a workbench or other area where you work


  • Limited range - it’s not going to heat a room, just a space

  • Needs to be hard-wired, although it is as simple as installing a light switch

  • Easiest way to control power is by adding a lightswitch to the wiring

When it comes to space heaters, a heater can only heat your garage or shop to your desired temperature proportionally to the size and insulation level of the space. It is also important to take into account the outdoor temperature you will be using the space heater to offset. All in all, these are all great options to accommodate different garage sizes and heating needs for all budgets.
