- Best Advisor
In its price range, it beats others hands down.
- iHome Mag
You can position the unit on the floor or counter but mounting it on the ceiling will give you the best heat payoff as you can then target the airflow towards the area of the garage you work in.It features an automatic temperature control which maintains a consistent temperature. The temperature that you will feel most comfortable with can be set via a thermostat to any value from 45 degrees to 77 degrees Fahrenheit.

The adjustable thermostat is somewhat inconvenient on the back panel of the device.

One thing that people have said they don’t like is the fact that it’s quite noisy.

An Overview On Garage Heaters

There is nothing worse than a freezing cold garage when you just need to get some work done. Whether your time in there is limited or extended, you won’t regret investing in a garage heater. With a flip of the switch, your garage will be toasty warm and your motivation will sky rocket.

There are several things to consider before purchasing a garage heater: First, you need to look at appropriately-sized units for the size of your garage. For calculated perfection, the rule of thumb is 10 watts per square foot of space.  If you have an average single car garage, you will want to check out units that are below 5,000 watts or roughly 15,000 BTUs. Whereas, a two or three car garage will need a much more powerful heater with roughly 10,000 watts or 30,000 BTUs. Second, there are a few types of heaters on the market. Propane or gas powered heaters, electric heaters, and portable radiant heaters are among your choices. Depending on which energy source is most efficient for your budget, you can decide on the best one for you.
