Atomi Smart WiFi Portable Tower Space Heater - 2nd Gen


What we love: Alexa and Google Assistant compatible, overheat and tip-over protection, oscillating feature.

The Smart Tower ceramic heater from Atomi checks all the boxes for an effective, reliable, and safe space heater for your garage. It puts out 1,500 watts, but according to Atomi and reviewers, it can heat up to 750 square feet. It's Wi-Fi enabled, compatible with Alexa and Google Assistant, and has three settings: low heat, high heat, and an eco setting.

Need extra peace of mind? It's cool to the touch, and not only does it offer automatic overheating and tip-over shut off, but you'll immediately get an alert if it does happen to tip over. However, with a wobble-free base, it's set up for minimal tipping.

De'Longhi TCH8093ERSB Ceramic Tower Heater

De'Longhi TCH8093ERSB Ceramic Tower Heater


What you'll love: Chic design, customizable temperature settings, space saver.

Things to keep in mind: Reviewers wish the base was sturdier.

This slim ceramic heater's sleek, smart design is its top drawing point, but the safety features make it a great choice, as well. Sitting at 28 inches, it's one of the tallest tower space heaters on the list, but the slim surface takes up less space than traditional tower heaters.

The De'Longhi heater offers tip-over shut-off and overheat protection, and it also allows you to customize its settings. The eco feature automatically reduces the heat when you've reached your desired temperature so you can finish that garage organization project without having to turn your heater on and off.

The heater is cool to the touch and has an automatic tip-over shut-off as well as an automatic shut-off once your desired temperature has been reached, so it's a good choice if you've got pets or kids to keep in mind.

How to Pick a Space Heater That's Right for Your Garage

Start by considering the contents of your garage (perhaps it's time to declutter). Do you have any flammable materials, such as gasoline, wood stain, paint thinners, or other oils and paints? Do children or pets have access to your garage? The answers to these questions will help inform your choice.

"Look for units with a tip-over shut-off feature and make sure the unit will not burn a child or fur baby if they touch it," advises Lanier English, corporate operations officer at McCoy's Heating and Air.

If you want to take the safest route, opt for a ceramic space heater over one that's infrared or propane-fueled. "Ceramic heaters have more safety features in place that would help to prevent potential issues," says Darren Hudema, director of training & technical services at PuroClean. Check that the space heater has been ETL (Electrical Testing Lab) or UL (Underwriters Laboratories) listed, says Hudema. This will indicate that it has completed a series of safety checks that render it safe for your home.

You'll also want to take into account the size of your garage or the area you want to heat. Traditionally, 10 watts heat a square foot, so if your garage is 200 square feet, you'll look for a space heater that's around 2,000 watts.

How to Safely Operate Your Space Heater

"Make sure that you plug your space heater directly into the outlet and not into an extension cord," warns Hudema.

He also explains that you can safely operate two space heaters in one garage as long as you're not exceeding the circuit rating. National electrical code requires that a circuit breaker trips at 80% of its load, so if your space heater is drawing more than that, plug them into two separate circuits.

To ensure the outlets in your garage are up to snuff, it's best to hire a contractor. You can search for electrical outlet and switch service professionals on Angi. The company finds contractors in your area who are equipped to handle your specific project.

For optimal heating, place your space heater in a cool corner of your garage and position the heater to face outward. Make sure the area around the heater is clean and free of anything flammable.

How to Maintain Your Space Heater

Keep your space heater clean and free of dust and hair. This not only keeps you safe, but it also helps your heater operate at an optimal level.

Make sure the filter, the unit itself, and the space around your heater are clean. Check the cord for any frayed or damaged parts. If it's damaged in any way, unplug it immediately. If it's a three-prong outlet, make sure it's grounded.

Taking into account our heating expert's safety recommendations, the following heaters are all ceramic, ETL listed, and offer numerous other features to keep you safe.
