240v vs. 120v Garage Heater
As winter approaches, one special thing every mechanic should have in their garage is a heater. Garage heaters come in different types, brands, and voltages. Among the most important factors to consider in an electric garage heater are watts and voltage. This is because electric heaters operate on electricity. The most common heaters come in 120V and 240V.
So what is the difference between 120V and 240V? 120V electric heaters are smaller and ideal for heating smaller basements, shops, garages, and rooms. 240V electric garage heaters are suitable for bigger garages. Let us learn more about 120V vs. 240V electric garage heaters.
240V Garage Heater
240V garage heaters are ideal when working in a large garage. These heaters can be plugged into a standard domestic 3-pin plug and are ideal for home garages and DIY users. One great advantage of the 240 garage heaters is that they use little electricity.
Pros and Cons
The best thing about the 240V garage heaters is that they produce more heat and are best for commercial use. The 240-volt garage heaters tend to consume less electricity than the 120-volt ones. On the downside, most of the heaters are large and bulky, and they cannot be carried from one place to another. They are only ideal for heating large garages where that is fixed.
120 V Garage Heater
A 120V garage heater is a small-sized heater ideal for heating just a small garage. You should only consider buying this heater if you are working in a small room. If your garage is more than 30*30 feet, you will need to buy an electric heater with a higher voltage. A 120V garage heater should be connected to a 120V outlet, the standard electric outlet in most homes.
Pros and Cons
The incredible thing about the 120V garage heaters is that they are small and portable. Therefore, these heaters work best in small spaces and are easy to carry from one room to another. The con of using 120V garage heaters is that they cannot be used in large rooms. Also, 120-volt heaters use more amps, thus consuming more electricity.
