Lasko 751320 — Best Electric Garage Heater (120v) Overall
This 120-volt garage heater from Lasko employs convection heating to deliver constant heat with uniform heat distribution. It heats up a medium-sized garage in about 15 minutes. Thanks to the self-adjusting heating element, the appliance automatically switches to standby mode when it reaches a certain temperature.
The heater automatically shuts off when it overheats. But the cabinet always stays cool to the touch, so it’s safe.
On the unit’s top, you can see a control panel that includes a thermostat, an auto-off timer (1hr, 2hr, and 4hr), oscillation, and two heating modes (900W and 1500W). By the way, both modes are almost equally quiet. There are also 7 temperature settings (from 60° to 85° and MAX). This garage heater electric (120V) also comes with a small remote control that has 6 buttons to change temperature, fix timer, etc.
The 751320 is 22.5 inches tall so that it can provide much more heat than compact, boxy models. Still, it’s slim and has a small footprint (7.25 x 8.38 inches). It’s also lightweight (5.6 pounds).
- The heater comes fully assembled: just plug it in an outlet, and it’s ready to work.
- Since the heater uses oscillation to distribute the heat, it can be used for heating up really large areas (up to 350 square feet).
- It has a non-slip base that reliably sticks to the surface.
- The cord is only 6-feet long.
- It may smell like burning plastic during the first hours of use.
- There is no tip-over safety switch.

How Many BTUs Does Your Garage Heater Need to Have?
The acronym BTU stands for British Thermal Unit. It denotes the unit of measurement for thermal energy in the English system of measurement. Although it’s used in the US as well.
To find out the perfect heating capacity that a heater should have to provide a perfect level of warmth in your garage, you will need to perform some simple measurements. The heating appliance should have 10W of power to heat one square foot. 1W of power equals 3.41 BTU. This way, you are going to need 34.1 BTU for each square foot. For example, let’s say you own a 240 square feet garage. This way, you will need a heater rated at 8200 BTU. Here is the formula:
1 square feet = 10 Watts = 34.1 BTU
|300 sq ft||3,000 W||10,200 BTU|
|450 sq ft||4,500 W||15,300 BTU|
|650 sq ft||6,500 W||22,200 BTU|
|800 sq ft||8,000 W||27,300 BTU|
|1200 sq ft||12,000 W||50,000 BTU|
Which Garage Heater Is The Most Effective?
Some 120-volt garage heaters electric can boost the garage’s temperature in a limited time; the others are designed for outdoor use and can heat poorly insulated spaces. Here are the pros and cons of the most popular types of electric heaters:
Infrared. Because infrared heaters only heat the area surrounding them, they aren’t the ideal solution for heating the entire space. In fact, such heaters are focused on heating objects and people instead of simply emitting warm air. In this case, they require a long time to warm the space. However, since such heaters don’t simply heat air, they are especially good for garages since they perform well in poorly insulated areas.
Fan. It works by blowing air across the heating element, creating warm airflow. Typically, fan heaters use a metal heating element. It’s one of the most cost-effective and simple-to-use/install options. They are also very compact (as usual). Fan heaters belong to a convection type of heaters which means that they can retain heat in the room for a long time even after you turn them off (depending on the room’s size and insulation, of course).
Ceramic. Such heaters use a heating element made of ceramic. To transfer heat, they can use either a fan or infrared method described above. Ceramic models can be considered the safest since they don’t take heat from electrical resistance.
Convection. Heaters of this type work like a convection oven. They transfer heat by moving gas or liquid. And the temperature increased faster than in infrared models. Nevertheless, convection heaters take a long time to heat spaces with high ceilings since they start heating from below.
