Best Propane Garage Heaters in 2021 [Our Top Picks]

There are plenty of reasons why you would want to keep your car garage cozy. Extreme temperatures will make it impossible to function in your space. Some activities are also thought of as seasonal because the effects are influenced by severe cold.

Painting, resin setting and several other activities involve precise ambient temperatures. You can complete these tasks with a heated garage even in the dead of winter.

Propane heaters will keep you working in your garage all year round. There is no need for costly renovations to install an HVAC system that could take months to install.

Electric heaters are expensive to operate and can also run a breaker if your room is not wired to high voltage appliances. Propane garage heaters will solve all your climate control problems without charging your electrical system or needing costly installation.

These space heaters will boost the time you spend in your garage right from the moment you walk into the house.

You might be wondering, is it safe to use propane heaters in such a space?

The answer is yes! Propane heaters are perfectly safe for use in the garage – if two items are available.

The first one is good ventilation for the exhaust pipe. The second is sufficiently fuel air to be used as fuel. They’re both very much available in the car garage.

Other safety measures should also apply: do not leave it unattended, put it in a place where it could be knocked, or allow children/pets anywhere near a propane heater.

How Does a Propane Garage Heater Work?

Propane heaters operate by releasing propane energy (which is a highly flammable hydrocarbon) with burning.

The ignition mechanism sets the propane on fire, and the mechanism (often made of porcelain) spreads the flame to help disperse the heat.

Remember, however, that the pilot light is operating constantly and uses very little fuel to be able to ignite the main light at a moment’s notice.

Benefits of a Propane Garage Heater

  • Reduce the time of vehicle warm-up. If your garage is held at a higher ambient temperature, everything from the engine to the coolant can take less time to warm up to an optimal operating temperature. The interior would take less time to warm up, too.
  • Increase the efficiency of household heating. Unless you have a detached garage, every wall you share with your house can exchange temperatures with the interior of your home. Keeping your garage warm decreases the drain, as your home heating system compensates for the cold walls of your garage.
  • Work happily in all seasons. If you enjoy spending time working on household projects, cold temperatures in your garage will put a damper on your plans. You can keep your garage comfortable all year round with a propane heater.

Types of Propane Garage Heaters


Radiant propane garage heaters increase the ambient temperature around them by radiating extremely high heat to their space. No additional movement of air is required to force the heat through the room. Many of the radiant heaters operate at higher temperatures. More heat is required when a space is heated without added airflow.

Forced air

Forced air propane garage heaters force air through the heating element. This heats the air flowing through the heater and pushes it through space so that more air is heated as it circulates through the room. These heaters will often operate at lower temperatures because the added air movement helps to heat up space.


All propane space heaters require oxygen to be burned. The vented propane heaters suck oxygen out of the room around them and transfer any gases out of the space through the vent. This prevents carbon monoxide from building up in space and improves the safety of the heater.

Considerations Before Buying a Propane Garage Heater

The following features are those that we have chosen to be the most relevant when you’re on the propane heater market. There are basic features that can calculate the important aspects of the heater, such as strength, reliability and ease of installation.

The categories below are the key parameters that we used to review our propane heater. There’s a lot to consider, but the features that leap on you are probably the most relevant for your particular.


There are a few different types of propane heaters available. Consider the ‘form’ when you make your purchase.

Do you need a wall mount for something? Do you need solid base legs to enable floor mounting? Looking for a portable option? The various types of propane heaters might be more suitable for individual needs.

You might think that a portable propane heater is the best one to use anywhere you need it, but these heaters take up floor space, while wall mounting solutions usually do not. You can place them on the wall and have them face the area you need the most to be heated.

Heating BTUs

The BTU rating is just one piece of the jigsaw. While you’re not supposed to base your purchase on BTUs, you can always look at this to check that you’re getting a propane heater with enough strength.

A low BTU rating is not going to be good enough for a big garage. This is why the BTU ratings are so prominently shown by the manufacturers of propane heaters. Another element of this is how the hot air is circulated throughout the building, which leads nicely to the next point…

Air Flow

The air flow relates to what happens to the hot air produced by the heater. Some people use infrared and do not even heat the air, instead they heat objects in the room, such as walls or surfaces.

One of the methods of air movement used is ‘forced air,’ which can drive hot air into certain places rather than hold it in one location.

Coverage Area

The coverage area is a mixture of each of these variables. As well as advertising BTU ratings, most propane heaters, portable and otherwise, will advertise the coverage area for which they are made. This is normally measured in square feet, so be sure to consider the square footage of your garage prior to purchase to fit the correct size of the propane heater.

Size and Weight

The measurements and weight of the heater are also factors that need to be taken into account before purchasing. You need to know that you’ve got space for the heater.

Also, if you’re going to install it on the wall, you both need to mark out the room to make sure it’s light enough to mount it comfortably on the wall.

We called Mr. Heater 40, 000 BTU our best for wall mounting because it is so lightweight and comes already mounted.

The weight of a device like this is certainly a consideration if you’re planning to buy a portable propane heater. If you want to take it to other places besides your garage, you’ll need to be able to transport it with ease, and don’t forget that you’ll also need a propane tank to go with it.


A one-year warranty is really the minimum you can expect from this kind of product. Of course, for a product like a heater, the longer the warranty, the better. If you can have a long warranty, it covers your purchase and guarantees that you can get a replacement if anything goes wrong.

Moreover, businesses providing long warranties appear to be more secure in the consistency of the product’s construction. For this reason, a long warranty is typically a symbol of a high quality product.


You’re going to need some kind of ventilation in the garage. This can come in the form of a window or some other form of vent. This will avoid toxic gasses from building up and creating possible problems and is a valuable safety feature.

Don’t worry, the advantages of a propane heater far outweigh the coldness of leaving a window open to let the air in and out of the space.

Price Range

The cheaper end of the market can sell some inexpensive propane heaters under $100, and in some cases substantially under $100. When you go for mid-range items, they’re between $100-250 and the very best on the market can be over $250.

These are rough, ball-park estimates to help you get an idea. There are, of course, elite items at the high end of the heating industry that are far over $250. Also consider buying propane to use with the boiler, and this isn’t necessarily the cheapest.

Key Features of a Propane Garage Heater

Sensor Tip

Propane heaters should have some simple safety features. Most models are fitted with a tip-over sensor that reduces fuel flow if the device is unexpectedly pushed out of balance. This prevents your room from being filled with explosive gas during an accident. This protection feature decreases the danger of inhalation of fire and propane.

Adjustable temperature remote

Any propane garage heater that you consider purchasing should have a simple set of temperature controls. Not only does this feature allow you to change the performance to your comfort, but it also allows you to retain fuel.


Propane garage heaters can be a lifesaver in cold weather. There’s nothing worse than hitting your source of heat to find that you don’t have a way to light it. This is why propane garage heaters with self-start features are perfect. Look for models that have built-in sparks or other ignition methods.

Safety Features

A propane garage heater is designed to provide you with complete protection. The critical safety features that the heater must have are:

Topple/Tipple over Cut Out

Heaters with bare flames normally create high temperatures and need to be knocked over. The naked flame is in danger of being burnt. Tipple or topple over cut will avoid such hazards as this feature by unintentionally tilting off heat generation.

Sensor for ODS or Oxygen Depletion

Propane garage heaters can emit a small amount of carbon dioxide, which can be very dangerous, particularly in the enclosed area. The ODS feature reduces this danger by automatically detecting lower levels of oxygen in a space.

High Temperature/Cut off overheat

This safety function is enabled when the temperature sensor of the heater exceeds the maximum level of safety. It decreases the risk of serious burns and reduces the risk of materials that can burn due to high temperatures.


The Heat Warranty demonstrates the faith of the manufacturer in their product. A product backed by a rich guarantee is built to last long and deliver high performance. If there is a situation where you are confused between two goods of almost identical quality, you can choose one with better warranty terms.


When looking for the best propane heater, you must remember its runtime as well. There is an indirect relationship between the BTU and the running time of any propane heater. The high BTU propane garage heater is expected to produce lower runtime while the lower BTU propane heater is expected to deliver high runtime.

Levels of heat control

A propane garage heater usually comes with varying degrees of heat control, typically in the form of a control button, control dial, or buttons on the side of the heater.

While a basic heater offers control of three range heat levels, including low, medium and high heat levels, advanced models which offer multiple settings. In addition to heat level controls, you can also check the outlet or regulation of the air flow.

Propane Heaters vs Electric Heaters

Propane heaters are easier to use than electric heaters, making electric heaters more expensive to operate. In reality, propane can reduce energy costs by a third. With this in mind, propane can be heavier than electrical, heating rooms much faster; it can also reduce costs.

Propane products appear to have a longer lifetime than electrical products. They are more reliable, and clean fuel prevents the components from breaking down, improving their durability. That said, electrical heaters are normally cheaper up front.

An electric heater tends to be quiet. Whereas propane heaters are a little noisy, making them less suitable in the bedroom. However, electrical heaters with a fan may also produce a mechanical sound.

In the stormier, colder months, electrical heaters would not be able to cope with those who live in places with inadequate electricity.

Propane tank can be stored securely in your garage, and can serve as a source of heat even if the grid goes down. This is equally true to people who don’t have electricity running to their garage.

Instead, propane tanks can be conveniently mounted and the garage can be heated without cables being installed. If it gets especially gusty in your garage, the wind could blow out the propane flame, making it more difficult to light. Electric heaters are a little easier to get going.

Safely Store a Propane Heater

As we covered above – using a propane heater in an indoor garage is fine, if you have adequate ventilation, either through an opened door, windows, or an actual ventilation system. It is important to keep these other tips in mind when using the propane heater in your garage:

Get your carbon monoxide detector

The first point of action should be to get a carbon monoxide detector to make sure it works! Carbon monoxide is truly an invisible killer, and using a propane heater in a garage is a prime example of a situation that a detector requires.

Inspect the tank of propane

Just because it succeeded last weekend doesn’t mean it’s going to be alright this weekend! At least once a month, make a good inspection of any teeth or scratches – particularly gas valves or rubber tubes.

Store tanks when they are not in service

Disconnect and store them if you don’t need them in the next 24 hours. Ideally, they should be housed in a well-ventilated garage or outdoors. Unlike other appliances, we want these outside to make sure that there is no possible harm if there is a gas leak.

Check for leakages

The easiest way to search for leakage is to use a soapy lather and kindly wipe it all over the tank. If you see some bubbles shimmering away, it might be a leak.

Move them right

If you’re moving/replacing tanks, make sure you hold them upright and protect them properly if you’re using a car. Placing it with you in the car? Roll down the windows to avoid any risk of being a little unconscious behind the wheel.


Propane garage heater is a great way to keep your space heated, without relying on access to a main connection. These can be perfect heating solutions for your garage or workshop, thanks to the large heating capacity and the low fuel heat factor.

The fact that you can take them anywhere, including camping, means that they have an infinite number of uses. They are the ultimate in portability, which is so uncommon to see in a market dominated by electrical appliances.
