Propane Space Heater Types

These are the 3 main space heater types:


Heat reflecting panels help to increase the intensity and direction of the heat making these heaters effective and efficient. They do not make a noise and are available in a range of sizes and heat options to suit your needs. 


Although a bit slower to get going, these heaters are good at warming a room for long periods. They are also a bit safer as the flame is enclosed. Convection heaters are economical to run and provide comforting warmth. 


These use a powerful air current to “force” the hot air. This helps to move it around and warm a large area quickly and effectively.

Vented vs Ventless Propane Space Heaters

Vented or Ventless – while setting up a heating system, basic factors like venting should be considered. In both scenarios “vented and vent-less” heating has its own pros and cons’. Most permanent wall propane heaters have vents, allowing the burned unwanted material waste out of the house through disposal pipes.

Ventless (or vent-free) heaters are portable making them convenient for working outdoors where there is enough air to mitigate any and all toxic emissions. While using vent-less heaters indoors, it always recommended to install a ventilation window or air holes.

Otherwise, carbon-monoxide may build up. Too much carbon monoxide can cause fatigue and finally result even in death, due to an insufficient supply of oxygen in the body.

Basics of a Propane Space Heater

When picking a propane space heater for your home, you have to evaluate precisely what task you require it to do. You have to first figure out exactly what your needs and options are, and then make your choice.

You can get a heater that is portable, that you can move from one room to the next. And if that’s not something you need, you can get a propane space heater that will be mounted in a specific location warming an entire house rather quickly. There are many various types of heaters to select, so you need to figure out what you truly need.

Advantages and Disadvantages of Propane Space Heaters


  • Compared to most heating solutions, propane heaters don’t operate with the aid of electric power. This makes them efficient, and especially handy during a blackout. They are also useful in places where there is no electricity in general.
  • They are also ideal while using in the field because of their portability. Regardless of the fact that it’s a bit cold outside, you can have an incredible night on your porch or deck with a propane radiator warming you.
  • A new space heater does not need to be costly; there are heaps of cheap warmers accessible. Even if you buy an expensive one, the fuel and operating costs are very cheap. Propane heaters are very economical and help you save over 65% when compared to other heating solutions.
  • Compared to kerosene, propane produces a clean environment when burning, making it more human-friendly in comparison with kerosene heaters, which can produce soot and nasty smoke.


  • Propane heaters require more maintenance when compared to other heating systems.
  • Dangerous exhaust fumes can enter the room if the system is not vented appropriately and in a timely manner.
  • Clearance necessities must be met if a fire springs out. You must make sure ignitable materials stay far from the unit heating system.
  • The environment in which the heater is located in must be clean and tidy. Dust and dirt can interfere with how the heater operates.

Propane Space Heater Safety

As the saying goes “SAFETY FIRST”. People often make the mistake of not reading warning labels and manufacturer guides. This can, at best, give you sub-optimal results from your heater. At worst, it becomes a serious health and disaster risk.

Safety Features to Look For

Fortunately, modern propane space heaters have good safety features as standard. Ensure that the one you get has the following:

High temp cutoff

You want to ensure that if the unit gets dangerously hot that is shuts down quickly and automatically. 

Tip/topple cutoff

A tipped over heater can be extremely dangerous. This feature will ensure that it cuts off instantly if it is tipped over. 

Oxygen Depletion sensor

Propane heaters can burn up the oxygen in the room under certain conditions leading to a serious health hazard. An oxygen depletion sensor (ODS) is essential to eliminate this risk. 

Quick Safety Tips

  • Portable propane space heaters should not be operated while being sleepy, this can cause an accident.
  • The recommended color of a perfect propane frame is blue, occasionally if the propane color changes to yellow or red, special attention is needed. It is recommended to contact  the system engineer in case of any inconveniences
  • The propane tanks should not be exposed to excessive heat, this may lead to explosions
  • For portable heaters, always attach and detach the system outdoors where there is enough air, incase the operations of the heater fail
  • Never work the heaters close to any combustible fluid or vapors. Keep all combustible substances far away from the heater.
  • In case a leak is detected, it’s always safe to switch off all appliances in the area to avoid the danger of fires and harm.
  • Disconnect gas pipes and valves if surrounding temperatures drop beneath -10° F and if the propane tank is empty. Keep propane amenities out of reach of unauthorized personnel and kids.


What is propane space heating?

Space heating is a technique where one employs to heat a small space commonly a working environment using a  propane heater compared to central heating where one has to warm the entire interior of a building.

How to connect a propane tank to a propane space heater?

Fortunately, most modern propane space heaters are easy to assemble and connect. Generally, they come with all the parts needed but in some cases, hose and other items might need to be purchased separately. Most will connect to all size tanks but some only work with specific propane tanks. 

You need to ensure you have the correct regulator, service lines, and connections. The heater should come with step by step instructions for easy connection. 

How much propane does a space heater use?

This will depend on the power output of the heater (BTU) and the setting on which you use it. The greater the BTU the more propane you will use. 

What size area can a propane space heater heat?

Again, this is determined by the BTU. A larger area will need a heater with a higher BTU. For small to medium sized indoor areas, 8 000 to 10 000 BTU should be sufficient. Larger rooms will need 12 000 BTU or more. 


Now that it’s obvious that propane is the most convenient fuel for your garage, following manufacturer’s guidelines and safety to the letter, will help you rip the full benefits of the system.

Many propane heaters offer an adjustable heat control setting that fits each individual comfort while operating the machine and also utilizing small garage space alignment.
