Best Propane Garage Heaters – 2020 Buyer’s Guide

| Last Updated: March 2, 2021

Propane heaters are particularly effective at heating garages. As garages are usually drafty places, it is important to have a powerful heater to provide the needed warmth. Electric is commonly used for this. However electric heaters tend not to be so effective, requiring a lot of electricity to generate enough warmth, making them costly. Propane is far more cost-effective. 

People often wonder if it is safe to use a propane heater in a garage. While it is safe, there are a few things to consider so that you use your heater correctly. There must be enough oxygen, which is usually not an issue in a drafty garage. Without enough oxygen, the poor combustion can cause carbon monoxide to form. Garages are actually a great environment to avoid this. Equally, make sure your heater is away from anything flammable, and that there is nothing cluttering the heater.

If your garage is poorly ventilated, a propane heater is perhaps not for you.

What to Consider Before Buying a Propane Garage Heater 


If you are looking to move your heater around, you need to consider how portable the heater is. Some models come equipped with ergonomic carry handles and lightweight designs to make lifting easier. 

Other, usually larger models can also be found with wheels. Try to look for reviews that highlight durability if being transported frequently in a car or truck.


If you’re choosing a model that isn’t portable and needs to be installed, consider where you will place the heater. Measure this space to find a heater that fits. While ensuring that it can structurally hold the weight. Lightweight designs with easy installation are best, or you will need to hire an installer, adding to the cost.

Size and Power

Consider the size of the space that needs heating. Garages are large as well as drafty, so you’ll need to consider that when a heater might say it heats 1000 square feet. Hot air is lost more easily in a garage. You will need something with slightly higher power and efficiency than you would for a regular, insulated interior room. While still being able to fit it into the area you have for it.


Not only do you want your product to cost less, but you also want it to be cost-effective. This means that you need to consider the running costs and thinking about the initial price.

When it comes to garage heaters, well-insulated and well-vented garages will be better served, with lower running costs. Equally, a heater that can cope with your needs without over-performing will run at a lower cost. Make sure you measure effectively and calculate the power you need. And search for a product in your price range that meets that.


Technological advancements have brought an array of added extras. Integrated thermostats will allow you to set an even temperature for your room. While automatic ignitions are far more convenient.

You may want remote control or to have specific settings. Or maybe you are keen for a digital display. There are all manners of features to improve operation and convenience.


Look for models that have tip-over protection to make the user aware if the heater is falling over. Equally, overheat protection will prevent the device from overheating. Look for heaters that incorporate carbon monoxide safety measures as well.

Propane Heaters vs. Electric Heaters

Propane is cheaper to use than electric, making electric heaters more costly to run. In fact, propane can cut down energy costs by a third. With this in mind, propane can get hotter than electric, heating rooms far more quickly; also reducing the costs.

Propane products tend to have a longer lifespan than electric products. They are more durable, and the clean fuel prevents the components from breaking down, increasing longevity. That said, electric heaters are usually cheaper up front.

Electric heaters tend to be silent. Whereas propane heaters are a little noisy, which makes them less suitable in the bedroom. However, electric heaters that have a fan can also make a mechanical sound.

For those who live in areas with unreliable electricity, electric heaters won’t be able to cope in the stormier, colder months. Propane tanks can be stored safely in your garage, serving as a heat source even if the grid goes down. This is equally true for people who don’t have electricity run to their garage. Instead, propane tanks can be easily installed, and the garage can be heated without installing cables.

If it gets particularly gusty in your garage, the wind could blow out the flame for the propane, making it harder to light. Electric heaters are slightly easier to get going.

Comparison Overview

The two popular choices for customers are kerosene and propane garage heaters. Let’s compare the working efficiency, cost, and safety of these products.

Propane vs. Kerosene Garage Heater

A brief contrast of these products is given below.

Safety and Health

The combustion of propane gas is of zero significance because it is considered as a source of clean energy, so the emission rate of a propane heater is nearly zero. 

On the other hand, the combustion of kerosene leads to a large number of toxic gases and fine soot particles. Some of the gases produced are Carbon Monoxide, Sulphur Dioxide, and Sulphur Monoxide. This can pose serious health issues.

Cost and Efficiency

Kerosene is known to produce more heat while burning than propane, but the latter is much cheaper and accessible to acquire. The efficiency of kerosene heaters is very less significant when the prices for the fuels are compared.

Time of Use

If you need to use your heater for a short time, then an immediate source will be required; in that case, kerosene heaters will be preferable while if you need continuous warmth and need to keep the heater running, then propane heaters are ideal.

How to Install a Propane Garage Heater

The installation of a garage heater isn’t really difficult and involves the following easy steps:

  1. In the first step, attach the heater's input to the external source of the propane, such as a cylinder or any other vessel. The pipe to attach the cylinder is given in the assembly tool kit. 

  2. You may need some tools to tighten both the ends of the pipe. Tighten the bolts at both ends using a wrench or any other fitting tool.

  3. Check for any leaks or loose bolts before using this apparatus at all times.

  4. Check the proper functioning of the pilot flame to prevent any emergency conditions and the loss of gas due to poor ignition.

  5. Open the valve from the cylinder to allow the flow of propane into the heater.

  6. Rotate the knob from pilot mode to the next heating point per your needs after the heater is lighted up.

That’s about it! If the steps are unclear, here’s a video of what was just described.


Propane heaters can be a wise choice for a garage. With the power to deal with the drafty environment, propane heaters cope easily with heating garages. Choosing radiant or convective heat is up to you, as it is the portability of your propane heater.

Always try to think of what you need to fit it into your space physically, as well as how it will be used in your life. This way you  will find a product that meets all your requirements, within your budget.

Forced-air heaters like propane with 45,000 BTU are enough for heating a two-car garage. Meanwhile, if you have an infrared heater, then for a two-car garage, 30,000 BTUs are enough.

Where Should I Place My Garage Heater?

To find the perfect place for your garage heater, keep the following in mind:

1. Find the coldest corner of the garage. You can use thermometers to do so.

2. Angle your heater such that it blows air towards the center of the door, leaving a minimum of 4 inches between the sides of the walls and the heater.

3. Keep all flammable materials 3 feet away from the heater’s front.
