5 Most & High Energy-Efficient Garage & Shop Heaters Reviews

Are you a person who spends a lot of time working, especially in spaces like a garage or shop? If you are, you should consider purchasing a garage heater.  Buying a heater that combines both quality and efficiency is very difficult, therefore you should read these suggestions.

I will present to you a list of the 5 best high energy-efficient garage heaters so you can have options to choose according to your requirements.

How To Choose A High-Efficiency Garage Heater?

Consider Your Garage Size

When purchasing a heater, the most important thing to bear in mind is the size of the space you’re heating. A too powerful heater might not be the most economical in a small garage, and a small one would be inefficient in a large shop with a high ceiling.

Choose The Right Power Source

All heaters do not use the same power source. Some are electric, some use propane and others use natural gas. They all do the job, but some are better in certain aspects than others. For example, an electric heater is good for heating large spaces quickly, while natural gas ones are more cost-efficient.

Wall Mounted Or Free Standing

Freestanding garage heaters offer convenience and portability. Depending on the size, you can more or less easily move it around. On the other hand, wall-mounted heaters are great space savers but can be a bit less energy efficient if you have a large garage.

The Amount Of Thermal Power Output

If you’re trying to buy and efficient gas-powered shop or garage heater, you must consider the amount of BTU it generates. Small garages benefit from 4000 – 9000 BTU, while larger spaces need upwards of 25 000 BTU. Electric 2500–5000 watts heater can efficiently warm up a medium-sized garage.

Multiple Adjustable Settings

Make sure your heater has multiple heat settings that you can adjust to suit the ambient of the room. Most heaters have a high and low heat setting, some have to fan only options for maximum energy efficiency. Other things you should consider are power cord length and if there are adjustable louvers for heat direction.
