By: John Garcia | Date Posted: January 17, 2022

Garage Heaters: Safe garage heaters: A garage can be an excellent place for DIYers and enthusiasts to start new projects. A garage may be a great area to keep tools and operate on various projects, even when it’s cold outside.

When it’s freezing outside, a garage heater could provide welcome relief from the chill. Every size of such garage, your type of fuel preferred if the heater needs to be portable, and critical safety features all play a role in determining the most OK garage heater.

Keep reading to learn about sure top garage heaters and what we found out about them during our testing.

Safe garage heaters: Stationary Vs. Portable

Take a look around your garage and decide what’s more important to you: having an extra counter and floor space or being able to work at many workstations. There are advantages and disadvantages to both types of garage heaters.


There are several advantages to having no cords and not stumbling over a radiator on the floor for dedicated DIYers. Stationary Safe garage heaters are installed regularly on the ceiling, but wall-mounted models are also available.

Sizes, energy options, and pricing abound from a few hundred dollars to very few thousand dollars. Mounted heaters have the disadvantage of being more expensive due to their higher quality than portable models.


It doesn’t matter what type of fuel is used or how it’s heated; portable heaters direct heat to where it’s most required.

Forced-air heaters have a powerful fan and massive horizontal tubes to hold the heating element, making them look like super-sized space heaters.

Despite their lower price tags, portable electric generators can have lower power outputs when compared to their multifuel equivalents. On the other hand, portable heaters can disperse heat by convection and radiant heat.

When Selecting The Perfect Garage Heater, What To Consider

Take a few moments to familiarise yourself with the most crucial buying factors, including the fuel source, heating method, and heat production, before making your final decision on the best garage heater.

As a result, there are also essential safety features that can keep you safe when using the heater.

Method Of Heating

All garage heaters are not created equal, just like any other heating system. Radiant, forced air, and convection all have their advantages and disadvantages.

It doesn’t matter how big or expensive the forced-air garage heaters are; they all work by cycling bursts of hot air into the garage.

The gas-powered model connects to a home’s gas supply. Unlike using electricity to provide the same amount of heat, using natural gas or propane is usually more cost-effective in the long run.

Water- or oil-filled radiators were used in convection garage heaters. Without the aid of a fan, they use an enclosed flame and heating element that warms the air inside the unit.

Like baseboard convection heaters, some should be affixed rather than being portable.

To heat a specific garage area or the entire building, big overhead units with highly polished reflectors are used with radiant garage heaters.

In the same way that sitting next to a campfire warms the ground around you, a radiant heater will quickly warm you up from the inside out.

The Source Of Energy.

When searching for a garage heater, consumers have a vast choice of alternatives to pick it.  Some heaters run on diesel and kerosene in addition to propane,  electricity, and natural gas.

Electric garage heaters require a separate electrical circuit with their breaker due to their high power consumption. For an electric heater, an electrician can determine if the garage’s current wiring is sufficient or if a separate circuit must be constructed.

Output Of Heat

The most fantastic garage heater for only one space can provide enough heat to be cozy without breaking the bank. British thermal units (BTUs) were used to measure the heat output of gas heaters (BTUs). Typical gas garage heaters can produce between 12,000 and 30,000 BTUs.


When purchasing a garage heater, safety should be the top issue. Manufacturers have included many safety measures for garage heaters, such as cool-touch exteriors, overheating prevention, and automatic shut-off systems, to maintain the space safe and comfortable.

Portable but wall-mounted Safe garage heaters often have exteriors that feel cool to the touch. Its outside casing comprises fiberglass or plastic, which are inefficient heat conductors. Despite the heat generated, the heater’s exterior remains unaffected.

An overheating protection feature guards against the heater’s self-extinguishing technology. Because unsafe temperatures can cause exterior and internal damage, the heater shuts down when it detects them.

Overheating protection is similar to automatic shut-off systems in that it responds by shutting down the heater should prevent damage.

In most cases, this system is activated when the heater is knocked over; however, other items still shut down, whereas the heater detects a short inside the wiring.

Features Not Included

The design of a garage heater might include oscillation, programmable thermostats, and remote controls, all of which make the warmer more appealing or easier to use.

Users can establish a target temperature for the heater by using an electronic keypad and perhaps a remote control, and the heater will only turn on to maintain that temperature.

Using portable garage heaters, oscillations are more prevalent, but wall-mounted heaters can include oscillating louvers (vents) that really can change the airflow direction.

With a nearly 180-degree spin, this feature aids in the optimum distribution of hot air around the garage.

Remote controls make it possible to operate the heater from virtually any location in the room, eliminating the want to get up and move over to switch it off or adjust the temperature.


May install a garage heater in a matter of minutes. An electric or gas source is all that is required for portable garage heaters to start working. However, installing Safe garage heaters mounted on the wall or ceiling is more complicated.

Even though mounting brackets are commonly included with these heaters, a few brands on the market do not. To ensure the heater is mounted correctly, manufacturers often include heaters that don’t come with such a mounting system.

Ensure that heaters installed in the ceiling seem to be at least twenty – four inches away from walls to limit the chance of a fire. Follow the manufacturer’s instructions to ensure the heater is positioned correctly and in the center of the garage.

Faqs- Safe Garage Heaters

Which Garage Heater Is The Most Energy-Efficient?

Electric infrared heaters may be more efficient than natural gas garage heaters, but they may cost more to run than the most efficient natural gas heaters.

Because electricity is more expensive than natural gas and even propane, this is why. Infrared heaters are the most incredible option if you seek a radiator that uses practically every watt of heat recovery.

Is It Possible For A Garage Heater To Be Too Large?

When a garage heater is too large, overheating the garage is a given warm-up when the car is currently immobilized in a too-large space.

To keep your garage warm, you may want to consider utilizing a portable heater instead of a traditional heater.

Do You Think A 1,500-watt Heater Would Be Sufficient For Heating A Garage?

The overall size of such a garage is an important consideration. An electric heater’s ability to warm up one square foot in space for every ten watts of output is a good rule of thumb, and this implies that a 1,500-watt heater seems more than adequate for a garage no larger than 150 square feet.
