Propane garage heaters allow you to affordably heat your garage no matter the size the weather outside. Before deciding if a propane garage heater is right for you, it’s important to do the necessary amount of research on the kind of heater you want to be installed in your garage.

Now, this is important to know. A spark ignites the propane fuel from the tank, and the fuel is heated continuously until it reaches the required temperature. This temperature can be set by the user, by just following the instructions laid out by the manufacturer.

A powerful fan in the heater blows the heated gas outside, creating warmth. As propane fuel is heated, a disposal pipe removes the by-product created by burning the fuel and sends it outside. With vent-free heaters, the heated air remains in the environment and so certain precautionary measures need to be taken.

Below we have listed the 5 best garage propane heaters currently available for sale online. This list will be reviewed and updated regularly.

Types of Garage Heating Vent Technologies

Unvented Heating      

An un-vented heating apparatus, i.e. – a vent-free heater is basically exactly what its name implies. This heater has no pollutant-disposal vent and is placed in the space that you want to warm up.

The advantage of this system is that no heat is lost making it reliant and economical. Many unvented heaters are cheap to acquire and do not depend on electric power. The heating process is quiet and convenient.

However, it has one issue. It pollutes the environment and causes more carbon-monoxide gas, because of its lack of a proper ventilation system. Oxygen levels are minimized and inhaling this gas too much can cause fatigue and even death

Vented Heating

With vented heating, disposal combustion waste is managed and expelled outside the heated area. This system is convenient and safe. Oxygen levels are maintained making it a little bit more expensive to install and run.

Expensive heaters with oxygen sensors make the system efficient and friendly. This is the main difference, all caused by its dedicated ventilation system.

Ventilation Requirements

Ventilation is one of the basic requirements when putting up a propane heater for your garage. The first thing is to consider what sub-type of heater you are getting – with or without a ventilation system. When using vented heaters, additional work and expenses are required.

These types of heaters require a vent pipe that takes care of the gasses that come up after combustion has taken place. They are much safer and cleaner. Vent-free heaters are also convenient since all you have to do is open garage windows so you can get a sufficient flow of oxygen into the garage.

Carbon monoxide is released when combustion takes place so venting should be done accordingly. As long as the carbon monoxide doesn’t build up in the place where you are using your heater, you will be good to go.

Types of Propane Garage Heaters

Many varieties of heaters are available on the market, and choosing the appropriate one requires serious research and advice. Different sizes vary and correspond to the power functions of the heater. A garage heater can either be portable or wall-mounted.

Mounted vs Portable Propane Garage Heater

The advantage of considering portable heaters is due to their adaptability to a different environment like outdoor camping. Wall-mounted heaters are more expensive but come with added advantages.

There are basically two options for propane garage heaters. Some heaters will require temporary fixtures while others will hook permanently into the wall, connected to a propane tank just near it or outside the garage.

The garage size should be the main factor here. Every heater’s effective performance varies greatly depending on the heat to square foot ratio. The type of installation should be the next important factor.

A wall-mounted propane heater should be perfectly aligned with the exact spot where heat is needed most, whereas a portable propane heater should be purchased with a guarantee to heat a given area. The garage should also be kept clean and dust-free to allow for good air circulation.

What to consider when purchasing Propane Garage Heaters

The span of your heater relies upon the size of the garage that needs to be heated. Wider garages consume more BTU (British Thermal Units) while smaller garages, of course, consume less.

The heater ought to have a thermostatic controller to keep the heating temperature leveled once a certain degree is achieved. The oxygen sensor in garage heaters is likewise a necessity, as it will turn down the heat if oxygen levels go too low. You should make as much room as possible for your heater, and try to keep it unobstructed by random clutter.


  1. The system is very efficient, powerful  and independent because it depends on boilers once fixed correctly
  2. Most Heaters have flexible louvers to help administer warm air where you require it most. The louvers make the heater reliable and spread heat exactly to the desired sport without wasting time before the heat is spread all over the entire garage.
  3. Propane garage heaters are 35% less economical when compared to other heating systems like electricity and kerosene.
  4. Durability is a factor as well. The heaters are well built and galvanized to avoid corrosion and wear, and high-quality paint is applied to give a durable perfect finish.


  1. Propane garage heaters require more maintenance and administration compared to other heating systems.
  2. Dangerous exhaust fumes can enter the garage if the system is not vented appropriately and in a timely manner.
  3. Clearance necessities must be met if a fire breaks out. You must make sure ignitable materials stay far from the unit heating system.
  4. The heaters fan  radiates huge volumes of air especially when adjusted to the limit hence creating dust in the garage when dust particles are brown violently
  5. The garage should remain clean to avoid tampering with the system.

General Safety Measures

  • Portable heaters should not be operated while in deep sleep, this can bring accidents, in case the heater‘s operations fail.
  • Never work the heaters close to any combustible fluid or gasses. Keep all combustible or ignitable substances far from the heater.
  • The propane tanks should not be exposed to excessive heat, this may lead to an explosion
  • For portable heaters always attach and detach the system outdoors where the air is sufficient in case the operations of the heater fail
  • In case you smell a propane leak, it’s always safe to switch off all appliances in the area.
  • Disconnect gas pipes and valves if surrounding temperatures drop beneath -10° F and if the propane tank is empty. This can cause unstable system combustion. Blocked gas pipes or nozzles should be replaced to avoid explosion risk. Lastly, keep propane amenities out of reach of unauthorized personnel and kids.
