Garage heaters are a great idea for almost any garage. Not only do they produce enough heat to leave your garage nice & toasty, it can actually be cost effective to do so. Before you buy just any heater, there are a few factors to consider. Read on to learn about what type of heater is the right choice for your garage.


In general, there are three main categories of heaters: forced air; radiant; and natural gas heaters. Pick the one that is best for your garage. Here's a little more info on each type of garage heater.

1) Forced Air Heaters - One of the easiest to install and also the most popular. This heater blows out warm air via a fan that draws in cold air from outside the garage. Typically it runs on electricity to convert the cold air into warm air quickly & evenly heats the space. (Some units will use natural gas or propane). These heaters are flexible to install and can be placed either on the garage wall or installed on the ceiling. Size, fuel & price will vary.

2)  Radiant Garage Heaters - Radiant heaters work by heating the area near the heater, without forcing air. It's a gentler heating method but the heater will have to be nearby to work efficiently. These heaters are better for garage shops or people who suffer from allergens, as these heaters won't stir up dust or debris. These units can be mounted or purchased as a portable heater. Radient heaters can be fuled by electricity, natural gas or propane.

3)  Natural Gas & Propane Heaters -  The benefit of this heater type is they can quickly heat a garage and are typically a cheaper fuel source. Wall-mounted units can be tied into your home's current gas line (providing you have one), making them less expensive to run. Extra care should be taken with these heaters particularly when used in an enclosed space. Proper ventilation is necessary to avoid any carbon dioxide build-up risks. As with anything that involves gas-powered units, you may be required to hire a licensed professional to handle the installation.



 In addition to fuel types, there are a few other factors to consider prior to purchasing a garage heater that is best for you such as:

1) Power - Garage heaters are generally rated in BTU's or watts. BTU is used for propane & natural gas heaters and calculates the thermal output of a heater. Watts are used for electrical heaters and calculates the amount of power needed to run. The higher the watts, the more power the heater provides and the more space it can heat. If you own a smaller garage than a more powerful heater isn't necessary. Size is imporatant here: the size of your garage should play a role in the type of fuel you choose. Smaller spaces may benefit from radiant hearers while larger spaces require more size & power, such as electric or gas.

2) Portable...Or Not? - Decide whether you want a fixed stationary unit or a portable garage heater. If you know you'll want to move the heater around, then a portable & natural gas fueled heater may be the one for you. Otherwise, a fixed heater with the right power & location will be the right choice. More powerful electric heaters will require 240-watts to run instead of the usual 110-watt power input. Hiring an electrician to do the wiring is important for safety & proper installation.

3) Safety Features - Saftey must always be considered. Most heaters come with a safety feature of some kind. Knowing what to look for specifically will help you make an informed decision. With natural gas or propane heaters a tip-over safety feature will turn off the unit if it gets knocked over. On any unit, an overheat protection will automatically shut off the power before the unit overheats. That is very important in an enclosed garage where hot surfaces may risk fires or can cause bodily harm if touched. For electric heaters, any auto-shutoff feature will protect the unit against any dangerous power surges.
