Buyer’s Guide: How to Pick the Best Choice for Your Money

It can get a bit confusing while making a choice on the garage heater especially when the market is full of many choices. They vary from the mode of their operation to the way they are powered and even the amount of heat they generate.
Thanks to hours of research on this topic, we have come up with a couple of considerations to keep in mind when shopping for a heater for your garage.

  • Source of Power

They are designed with a variety of power sources ranging from electricity to propane and natural gas. Electric heaters are the most common and come with low maintenance. Plus, they pose the least risk to your safety as they come with auto shut off features. On the other hand, natural gas and propane heaters are known for providing heat that is about 5 to 10 times stronger than what you will find with electric heaters. Plus they are pricier and more portable than their electric power counterparts.

  • Garage Size

Choose one with enough power for your garage space. Choosing a heater that is too powerful for your space will lead to too much heat in the room. Consider the height of the ceiling while choosing a heater. With a 6 to 7 feet high ceiling, you may need a more powerful heater with a punch in its fan force.

  • Safety Features

obviously, safety is an important feature, especially with heating appliances. Some of the safety features to look out for in a garage heater include a tip over the off switch in case it gets knocked over. You also need an overheat protection feature as it will prevent your heater from producing excess heat levels. Some heaters will also come with a cool touch or wire guard feature that will prevent accidental burns from touching the wires.

Conclusion

For most people, their workspace set up in their garage can get unbearable in winters, preventing any work from being done. Luckily there are many options in the market that offer quick and reliable solutions. Without pick of 10 of the best garage heaters, there is no doubt that you will find a good fit.
