Propane Heater Compared to Other Heater Types

Gas vs Propane

Although gas garage heaters are quieter than propane heaters, you can still have the same BTU level from a gas and propane heater, so you won’t be limited by the space you are looking to heat. Propane heaters are much more portable than gas heaters, making them ideal if you want to use them in a variety of locations.  They also are more likely have a fan to circulate the air around the room and achieve an even temperature.

Electric vs Propane

Electric heaters are generally heavy or fixed on the floor or wall.  Again, propane heaters give you the convenience of moving them around so you aren’t limited to only warming one area. Electric heaters are generally quieter than propane heaters, which may be better for quiet areas where you need to concentrate.  They are also much lower in maintenance, which can be a huge benefit for someone with little experience with space heaters.  However, they are also generally lower in power and cannot heat as large a room as propane heaters.  So, if you are looking to heat a larger room, a propane heater is the option for you.

What is BTU and How Much do You Need?

BTU stands for British Thermal Unit and these are the units you will need to heat around one pound of water by one degree Fahrenheit.  In terms of a space heater, it is often a point of reference for the ability to heat a certain area.  Therefore, depending on the space of the area you would like to heat changes the BTUs you will need.

Area to be heated    /    BTUs Required

100 up to 150 5,000
150 up to 250 6,000
250 up to 300 7,000
300 up to 350 8,000
350 up to 400 9,000
400 up to 450 10,000
450 up to 550 12,000
550 up to 700 14,000
700 up to 1,000 18,000
1,000 up to 1,200 21,000
1,200 up to 1,400 23,000
1,400 up to 1,500 24,000
1,500 up to 2,000 30,000
2,000 up to 2,500 34,000


  • Make sure the room is properly ventilated.
  • Read the owner’s manual to ensure that you understand the maintenance required and that this is done within the recommended timeframe.
  • Remember to turn off your space heater when you are not present to monitor it.
  • A carbon monoxide monitor and thermometer are great extra purchases to ensure the safety of those around you.
