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.

Vented vs Ventless Propane Garage Heaters

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.

Propane Garage Heater Types

Radiant

These heaters have reflective panels that maximize and direct the heat. They are silent and do not blow air. They come in a range of sizes and a good option for heating a garage. 

Convection

Convention heaters usually have an enclosed flame and use an element to transfer heat to the room. They can take a bit longer to warm up but give safe, consistent heat and might save a bit on propane costs in the long run. 

Forced

Forced heaters to work quickly and effectively by using hot air to distribute the heat. They can be ideal for larger areas. The downside is that some of them can be quite noisy and they will create a bit of wind. If you are working in the garage this may be an issue. 

Mounted vs Portable Propane Garage Heaters

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.

Pros

  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.

Cons

  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.

Propane Space Heater Safety

There are three main safety features a propane heater should have:

High temp cutoff

If the unit gets too hot to operate safely it should automatically shut down. 

Tip/topple cutoff

When the heater is bumped, blown, or knocked over, it should immediately shut down to prevent any accidents or safety risks. 

Oxygen Depletion sensor

If operating incorrectly or without any ventilation, oxygen could be depleted. This is a dangerous situation and the heater should have an oxygen depletion sensor to prevent this. 

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.

Is it safe to heat a garage with propane?

Garage propane heaters are designed to be used indoors and have a number of safety features to reduce the risk of using them. Provided you have some ventilation, follow instructions, and use them correctly, they are perfectly safe to use in a garage. 

Can I also use my propane heater for the garage for warming the whole house?

A: Your garage heater can be used in other parts of the house but many of them do not look extremely attractive. They can heat rooms in the house but will not be effective in warming the entire house. 

How much propane does a garage heater use?

This will depend on the heater type (see above) as well as the power or  BTUs it produces. Most have 2 or 3 heat settings so it also depends on the setting used. Propane is an effective and economical way to warm a garage. 

Conclusion

Propane heaters have been successfully utilized for decades now. With only a few things to worry about and the occasional refill, the system works efficiently saving you a lot of money. They are also much more efficient when compared to old-school electric heaters (fortunately new technology has since been developed). Also, fuel is relatively cheap and is readily available.

Garage heaters vary, and its best to consult a certified and trustworthy engineer, as well as follow all preparatory and operating measures. You will definitely be blown away after installing this system. Always remember to allow some ventilation into your garage.

Now that it’s obvious that propane is the most convenient fuel for your garage, following manufacturer’s guidelines will help you make the most out of your heater. Many propane heaters offer adjustable heat control settings that fit each individual comfort while operating the machine and also utilizing small garage space alignment.
