What factors should you consider when buying a garage heater?



There are numerous things that you should ask yourself before selecting a particular garage heater.

These include:


The garage size
How big is your garage? If it is slightly small, you should choose a less powerful heater so you can get just the right warmth.

Large garage spaces, on the other hand, require a powerful heater so that the heat can reach each point. Also, you might want a freestanding garage heater so you can move it around as you work.

If your garage is high, going for a fan-forced heater will help distribute the heat to the whole space.


Source of power
Garage heaters are manufactured to utilize electricity, propane, or natural gas.

Gas-powered heaters are ideal for large garage spaces because they heat up real quick and are economical for long periods of use.

Nevertheless, you need to consider the danger of using a gas cylinder in an enclosed room. You have to check it often to ensure that it is in a good working condition. You will also need to install a ventilation system to let toxic gases out.

Electric garage heaters are a good choice for small to medium spaces. You should go for them if you are looking for heating consistency. They give adequate infrared heat and superheated air.

Electric heaters also feature automatic sensors that allow you to control the heating level. The sensors will also notify you in case the heater is knocked over.


The type of heater
Infrared or radiant heaters are perfect for small spaces. This is because the amount of heat they generate is less powerful but quick.

Infrared heaters may be freestanding or wall-mounted. The wall-mounted heaters limit where you heat so you have to stay around them for warmth. Freestanding radiant heaters are most preferred since they are portable.

The fan-forced heaters are perfect for large garage spaces. This is because the heat generated can be distributed evenly throughout the room. This way, the garage stays warm for longer. What’s more, the fan-forced heater may come with a switch so you can turn the heat off. The fan, however, is left on to get rid of the stuffy air.


Power output
The power output level of gas-powered garage heaters is measured in BTU (British Thermal Unit). The electric-powered garage heaters, on the other hand, have their power output indicated in watts.

For small garage spaces whose ceiling is not more than 250 feet high, you should go for 4,000 to 9,000 BTU. This amount of heat will keep the room warm enough for you to work comfortably.

For garage spaces that are over 500 feet high to 600 feet, a gas-powered heater of 25,000 BTU is sufficient. If you must use an electric a powered heater for such a garage, consider those producing 2500 – 5000 watts.

If your garage is 1,000 feet and more, we recommend that you go for a gas-powered heater whose power output is 30,000 to 60,000 BTU.


Other features
If you are looking for a fan-forced garage heater, you should buy one with adjustable louvers. This feature will allow you to control the direction the heated air should flow.

The best garage heater should have a handle for ease of portability. This way, you can carry it around without touching the burning surface. This is particularly essential for freestanding heaters as you can move them while still generating heat.

The length of the power cord or hose is also an important factor to consider. This is not a problem with propane heaters since most of them come with a 10-foot long hose.

For electric heaters, a 6-foot long cord is most common for adequate flexibility within the garage.

As you are busy working in the garage, the heater may be knocked over. As a safety measure, most heaters feature tip-off switches or sensors that alert you in the event of a knock over.

Touching the hot surface of the heater is dangerous. This is why manufacturers fix cool-touch or wire guard features for your protection.

Heaters are also designed with overheating protection so they can turn off automatically before they flameout.
