Space Heater for Uninsulated Garage: Buyer’s Guide

Before buying a space heater you must consider a few factors which I’m going to address now.

Fixed or Portable:

You must decide first whether you will move it into different rooms or it will be fixed in a particular spot. If you are not going to move it so often, you should go for a space heater that can be mounted into a wall. Otherwise, a lightweight and portable heater is all you may need.

Safety Features:

You should look for some safety features in it. It must have a tip-over switch so that it can shut off automatically if it is knocked over. Besides, the heater must come with overheat protection and a cool-touch feature to get complete safety from it.

Carry Handle & Wheels:

When you need a portable space heater, the first thing you must look for is the carry handle so that you can move it into places without any hassle. Also, keep in mind that some heaters come with wheels and castors to make them more portable.


You can’t deny their importance of them. Always try to buy a space heater that has adjustable louvers so that you can direct airflow to your desired direction.

Cord Length:

The last but not the least important factor you must consider is the length of the power cord. It is not safe to use extension cords with a high-power space heater. So, the wise decision is to get a product with a long power cord.

Why Space Heaters Are Different From Regular Heaters?

When it comes to a space heater for use in your garage, they are typically larger compared to those regular heaters designed for homes. In most cases, garage heaters come with a large heating capacity because of the nature of the operation.

In a general sense, you will not use a space heater to heat an entire room. Rather you will use it to get additional heat to make a specific area of your garage warm. Now, when you talk about garage heaters, they don’t come with an HVAC system. So, they will not get any additional support to get the job done.

That is why garage space heaters are typically larger so that they can generate enough heat to make the garage environment warm. Besides, these heaters have a great level of durability if you compare them with standard home heaters. You also get much flexibility when installing a space heater in your garage.
