Factors to consider when choosing the best heater for uninsulated garage

1. Type of heater you want

Heaters use different methods of heating and also produce different amounts of heat.

Propane heaters, for instance, produce higher amounts of heat than infrared or oil-filled heaters.

If you have a large garage space, it is advisable to choose the propane heaters since they have the ability to provide large amounts of heat.

Example of a Propane Heater

However, if you have a small garage, you may opt to use oil-filled heaters that produce a little amount of heat.

2. Size of the heater

The size of the heater also matters. Small-sized heaters produce a small amount of heat and therefore they can only be used in small garages.

If you have a large garage area or two garage spaces, you may need a big heater that can produce a lot of heat to warm the whole space effectively.

For small spaces, small-sized heaters will work perfectly since you don’t need a lot of heat.

3. The power rating of the heater (BTUs)

You have to consider the power rating of the heater for your garage.

The best heater for your garage will produce the maximum amount of heat at very low settings.

A good example is the Dr. Infrared Heater DR-988A Garage Shop 208/240V, 4800/5600W Heater with 6-30R Plug which produces a very high amount of heat at very low settings.

This heater has an advantage over the DeWalt DXH150FAV Forced Air Propane Heater produces a large amount of heat at very maximum power settings.

4. Fixed or portable heater

The portability of the heater is also a very important aspect to consider before installing your heater.

A good heater should be able to be moved from one place to another depending on where you want to heat.

Most of the oil-filled heaters are usually bigger and heavier than the propane or infrared heaters. Thus, they cannot be moved around easily.

5. Length of the power cord

It is very important to determine the extent to which the power will be supplied in the garage. This will help you choose a heater with an appropriate length of power cord for heat supply.

Heaters that have very long power cords can supply heat to very large areas as compared to those that have shorter power cords because they can be moved from one point to another.

Most of the infrared heaters have very short power cords and this is the reason why they cannot supply heat to very large areas. On the other hand, most propane heaters have very long power cords and can supply heat to very long distances.

Safety precautions when using an uninsulated garage heater

1. The heater should have overheated protection

Most of the uninsulated garage heaters are run by either oil, propane, or infrared light and produce a lot of internal heat.

The heat can be a very big threat to your garage because it can lead to fire outbreaks if not regulated.

This is why each and every heater should have an overheat protection. It helps to ensure that the heater is automatically shut down once the temperature goes above the set limit. After the heater has been shut down, it can be restarted once it cools off.

2. It should have a tip-over switch

Some of the oil-filled garage heaters are portable because they can be moved from one place to another.

One of the threats of this heaters is that they can present a fire hazard if they are tipped over facing downwards.

If the heater is tipped facing downwards and comes across a combustible material such as a piece of cloth or paper, it may lead to an outbreak of fire.

That is why each and every heater is equipped with a tip-over switch at the bottom.

The tip-over switch helps to automatically shut down the heater system if the heater is accidentally tipped over.

Heaters should be equipped with a 3600 tip-over switch to allow automatic shut down of the heater system if they are accidentally tipped over.

3. Should have a cool to touch feature

An example of the cool to touch feature in the heater is cool to touch handle.

The cool to touch feature helps to prevent burns when one accidentally touches the exterior part of the heater.

The internal heat produced by the heater makes it to be extremely hot and can cause serious burns especially if you want to move the heater from one part of the garage to the other.

The cool to touch feature provides good safety measure especially in places where there are children or pets.

4. Should have an excellent fan system

High internal heat produced by the heaters usually reduces their lifespan.

An excellent fan system helps to blow away the excess heat produced by the heater.

This helps to ensure that the heat around the heater is kept at optimal levels to prevent damage to the heaters.

5. Should have an in-built thermostat system

An in-built thermostat is a very important component of the heater. The thermostat system also controls the amount of energy used by your heater by regulating its heating system.

It achieves this by monitoring the temperature variations of the heater such that if it is high, it is regulated to prevent overheating.

This temperature regulation also ensures that your heater cools to the required level.


In conclusion, the best heaters for uninsulated garage are very important at ensuring that the temperature around the garage area is maintained. There are very many types of heaters that can be used in garage areas. However, the choice of the heater depends on the size of the garage and also the amount of power that is to be consumed in the garage.

A good heater should be flexible, high power rating, and should also be large in size depending on the size of the garage. Furthermore, you should also take the necessary precautions that you need to observe before observing the heater, for example, the thermostat system, the fan system, and also the cool touch features.
