Generic heating device solutions are always a recipe for you being completely unsatisfied with your purchase. While the very cheap price tag is enticing, it actually can cause you a lot more in the long run due to higher heating bills from an inefficient device, repairs that are needed after only a year or two, or a complete replacement when you realize that it just doesn't perform as well as it should.   Instead, you need to stick to electrical heater solutions for your shop or garage that are from trusted brands. There are quite a lot of brands out there that are worth looking at like Fahrenheat, NewAir, King Electric, Mr. Heater, Comfort Zone, and more. While all of these brands are decent for larger garages or shops, they tend to specialize in different features.   Some of these heaters have louvers and are ceiling mount portable garage heater. Others are freestanding direct air heater with tons of airflow in one direction. Some can be plugged into a standard 120-volt electrical outlet. Others require more amps and need to be plugged into a special 240-volt outlet. Some are heavy-duty for huge shops, while some are smaller for smaller areas.   Check the features and ratings of the heater you are looking at carefully and make sure it meets the needs of your specific shop or garage heating situation.
