Best Garage Heaters Buyer’s Guide

Not all of the best heaters for garages are built the same.

There are many features you need to consider before you can decide that a model is truly the right one for you.

It is important to take a look at the method in which the heater will warm your garage, whether or not the model is portable, its total heating capacity, and the attached fuel source.

You might also want to consider getting a good garage heater that includes extra safety features like an automatic shutoff system.

Let’s understand some of the key features that you need to look at when purchasing a garage heater.

Heating Type

One of the most critical steps in choosing the right garage heater for you is selecting a heating style or type.

Most modern heaters fall into one of three categories: forced air, convection, and radiant.

Forced Air

A forced-air garage heater is one of the simplest options.

In this device, the air is pulled into the machine, heated by an energy source, and then blasted out at incredible speeds.

The result is the quick dispersion of heat through a large area with little difficulty.

Convection

Aptly named, a convection heater uses the scientific principle of convection to heat air over a more extended period.

Inside each device is an enclosed flame or filament, which serves as a primary heat source.

Cold Air

For this machine, cold air is pulled into the machine and passed over the source until it is warmed.

The warm air moves up and then blasts out of the heater.

The cycle continues with the heater, pulling in cold air to be warmed continuously.

Radiant

Radiant heaters are the hardest for the average person to understand, and they also supply heat over time rather than emitting huge gusts of warm air.

In a radiant heater, there are highly polished reflectors that direct infrared heat outward.

These reflectors are heated from an internal power source and provide a steady supply of warmth without disturbing dust or particles in the garage.

So, which one should you choose?

The right heating type for you will largely depend on the size of your garage and the type of activities you plan to complete.

If you are into woodworking, for example, you might like a radiant heater because it will not stir up shavings and splinters while working.

Portability

A lot of great heaters for garages can also be portable if you know where to look.

A portable heater will be small and will often have a temporary power supply like propane that can be emptied and refilled.

Since portable options are small, they tend to heat a smaller area than their permanent counterparts.

Therefore, if you do not need to worry about moving your garage heater around, you can consider permanent options.

One of the best choices for a garage is a device that you can mount to the wall or even the ceiling for regular use.

Mounted heaters often include extra features like adjustable thermostats, built-in safety features, and remote control options.

You can also connect them to your home’s primary heating source, so you don’t have to worry about having a separate one.

The main downside to using a mounted option is not having heat aimed directly where you need it.

Instead, these units will focus on warming the entire room.

If you want a heater that can move with you and directed at your workstation, go portable.

Capacity

Before purchasing any heater, you also need to consider its capacity.

It might be tempting to get the largest heater you can afford, but does it really suit your needs or lifestyle?

Capacity refers to the output of the heater, which is measured in British thermal units (BTUs).

Since manufacturers often list BTUs with the heater, you thankfully do not have to complete any equations.

Manufacturers know the average buyer doesn’t want to calculate just how many BTUs they need, so most heaters will also list how much square footage the heater can cover in a given time.

How to Identify the Right Capacity You’ll Need

To learn your desired capacity, you need to measure the area of your garage or workstation.

You can do this by multiplying the length and width of the area.

If you want to be more complex, you can also add the height.

When thinking about capacity, you also want to take a good look at the garage insulation, plus if there are any areas where heat is likely to escape.

Are the doors and windows properly installed?

Are there any cracks in the walls?

Will you have the primary garage door open when the heating system is running?

Such issues will increase the heating capacity you need to remain comfortable.

Finally, know that your desired capacity will affect the type of garage heaters available to you.

If you need to heat a small area, for example, a forced-air heater might not be right for you because these models are intended for large spaces and will often blast too much heat.

Power Source

You need to figure out what kind of power source you want to use for your heater, especially since the power source is how the device will generate heat.

In the modern age, you have a couple of options to choose from, including electricity, natural gas, and propane.

Each of these energy sources has its own pros and cons.

Electricity

Electricity can often be connected to your home’s power source or might just require plugging into an outlet in the garage.

Some options can also use powerful batteries that you can charge as needed.

The downside is that electricity can be expensive and might increase your energy bills over time.

Natural Gas

Natural gas often requires having a natural gas hookup in your home.

These heaters are powerful and beneficial, but can once again be expensive if you don’t have the setup for it.

Propane

Propane is another popular option, particularly for portable heaters.

These heating devices have connections where you can attach a propane tank.

They are often the most affordable to operate but can be a significant fire risk if you don’t use them safely and in open areas.

Others

Besides these main choices, some manufacturers also make heaters that use diesel and kerosene.

However, these are not good for garages because they often emit fumes that can make an enclosed space toxic quickly.

They are also often expensive and difficult to keep operational for the average person.

Safety Features

Finally, you want to consider whether the heater has any safety features.

These features become more important if you choose models that have an open flame or pilot light since these can quickly become major fire hazards.

Some of the features to search for include an automatic shutoff and an ODS.

Auto-Shutoff

Automatic shutoff is a feature that will switch off the entire heater if the device is knocked over or becomes too hot.

It stops flammable gas from being released and will also switch off any pilot light, so you don’t have to worry about the flame spreading or burning the internal mechanisms of the heater.

Most modern options are required to include this feature, but not all of them have it.

ODS

An ODS or Oxygen Depletion Sensor is the other main safety feature to look for and stands for.

It is a light or alarm that will switch on if toxic fumes like carbon monoxide start to fill the garage.

This feature is particularly essential if you plan to use a model fueled by propane or natural gas since it will alert you if there is a leak in the primary power supply.

Others

Some additional features are a heat-resistant exterior and protected dials to ensure you don’t burn your fingers.

Garage Heater FAQs

What Type of Heater Is Best for a Garage?

Most garages are small, enclosed spaces that do not require tons of power to remain heated.

For these reasons, the best types of heaters are convection or radiant models.

These will drum up consistent temperatures without disturbing too much dust or too many wood shavings.

The one model to avoid in a small garage is a forced-air heater because these devices are intended for larger spaces and will generate too much force and hot air.

You can use a hot air heater, though, if you have at least a two-car garage or something larger.

How Many Btu Does It Take to Heat a Two-Car Garage?

It is difficult to create an accurate estimate of how many BTUs are required for a two-car garage since the garage itself could be of any size.

That said, most people and experts estimate that at least 45,000 BTUs are needed to keep the entire area heated, while 60,000 BTUs will work if you are looking for a warmer or more comfortable temperature.

You must also keep in mind, though, that a different amount of BTUs might be needed depending on the type of heater you want to use.

The above numbers work well with forced air heaters, but lower numbers would be needed for convection or radiant models.

How Can I Heat My Garage Cheaply?

Besides getting a good garage heater, there are other ways you can keep your garage warm without too much cost.

One of the most popular is by maintaining good insulation.

The spaces around windows and doors are often the places where warm air will leave and cool air will enter.

You need to make sure these cracks are properly sealed by applying a regular coat of sealant and filling any cracks.

Some construction companies are also willing to install insulation.

Where Should I Place My Garage Heater?

There are multiple options for where you can place your garage heater.

Most experts, though, recommended choosing the coldest corner or location and using that as the primary place of installation.

If you have a small, portable heater, you can usually place it on a table so that it heats the air at a head level.

If you choose a permanent model that you need to install on a wall or the ceiling, try to place it at least seven feet above the floor.

Once again, this helps ensure the air around your head will be heated properly and keep you warm even during the winter months.

Will Insulating My Garage Keep It Cooler?

Insulation isn’t just meant to keep an area warm during the cold months.

It can also stop heat from escaping from your home or garage during the summer.

It does so by restricting airflow and keeping the desired temperature of the atmosphere inside rather than outside.

Best Garage Heater Recommendation

The five products we reviewed are some of the best garage heaters on the market, but there can be only one winner.

Out of the five models, our personal favorite is the Mr. Heater F232000 MH9BX Buddy Heater because it has plenty of reliable safety features, such as an automatic shutoff and oxygen depletion sensor.

It is also inexpensive to keep fueled and is highly portable.

For individuals who would like something more powerful, though, the Mr. Heater MH60QFAV Forced Air Heater is a great choice.

It can heat a large commercial garage without difficulty and also comes with easy to use controls.

It could even work in a greenhouse!
