Indoor propane heaters give you the benefit of an open fire without the concerns that come along with it. Indoor propane heaters are characterized by its size (small-ish like the portable ones), weight (they’re also normally under 10 lbs), mobility (you can also move them around) and build (you can normally set them up, down and sideways to point to someone or something, as well as see the flames or heat source).

Modern indoor propane heaters are a great way of providing a little extra heat for a chilly room on those cold winter nights. These heaters are designed to be safe, efficient and easy to use when needed. Many models use bottled propane to produce their heat, which is an inexpensive and easily accessible fuel in most areas. Some of the better models also feature thermostats that allow you to maintain constant temperature automatically throughout the night to conserve fuel. Indoor propane heaters fall into one of two categories and are considered either portable or permanent (wall).

Different Styles of Indoor Propane Heaters

Portable Indoor Propane Heaters

A portable indoor propane heater can be moved easily wherever needed and is typically smaller in its heating capability. These heaters are normally used to augment an existing heating system that may need a little help warming an area of a home on a, particularly cold night. A portable indoor propane heater is also great for providing heat while camping or during a power failure since many models are self-contained and require no external power. While these two styles of heaters may operate in a similar way, their size and the amount of heat they can produce is different. For most homes, we recommend a portable propane heater, as it’s affordable and easy to move around.

The Benefits of a Portable Indoor Propane Heater

The single best feature of any portable propane heater is that it can be moved to wherever it’s needed for heat. These units contain everything required for operation and can supply warmth instantly, with the flip of a switch. Although they may be smaller than other types of heaters, they can still produce an abundance of heat from a single propane canister. Their portability also expands their use beyond the home and allows you to take them along when hunting, fishing and camping. They provide the perfect solution when you need a little extra heat to chase away the cold.

Permanent Indoor Propane Heaters

A permanent indoor propane heater is different since it is designed to be mounted to a wall in the home. Some models are attached directly to the wall in the room you are heating and others are installed inside the wall, between the beams. These permanent indoor propane heaters are attached to a larger tank of fuel that is located outside the home, near the heater. The larger storage tanks are fixed in place for use and filled by a delivery truck.

These permanent indoor propane heaters are larger in heating capacity than a portable model and are intended to heat a bigger room or an entire house. Most models employ a circulation fan inside the heater to distribute the warm air where needed. Because of their size, these heaters produce a larger volume of exhaust gas that must be vented outside the home for safety.

Larger Models for Heating a Home

This same technology is used on larger indoor propane heaters that are designed to heat your home. These models are permanently mounted to a central wall in the house and can deliver warm air to the entire dwelling. This type of heater is a great alternative to other heating systems like gas or oil, especially in remote areas where these fuel types are not readily available.

These larger propane heaters are designed to operate as a normal heating system and feature a thermostat that controls the heater’s operation. You can set it to the desired temperature and the system will respond with the required heat to maintain that temperature. These heaters will vent to the outside of your home for safety and operate so quietly that you’ll almost forget they are there.

Unique Safety Features Used in Indoor Propane Heaters

Indoor heaters employ several additional safety features not typically found on outdoor models. Because of the need for these safety improvements, it is critical that you never use an outdoor propane heater indoors, even for a short period of time. All indoor propane heaters will be certified for indoor use. These specialized heaters include a collection of safety features like a low oxygen detector that shuts off the heater when the air in the room falls below a safe level. All models of indoor heaters also include tip protectors that extinguish the flame if the heater is knocked over. These protections help to make them safer for indoor use.

A portable propane heater is a great appliance to have when you need to temporarily heat an area. They use inexpensive fuel that is easy to find at a local hardware store and will operate for hours on a single canister. They produce strong, consistent and clean heat that will keep you warm throughout the night. The latest versions of these heaters are less expensive and more efficient than ever before and provide a very safe heat source for your home.

Ignition Type – Automatic Vs Manual

Manual type ignitions will always be less liked for the very first reason you can think of. It’s manual. At the same time, this brings a lot more safety. Automatic ignition types are also safe and reliable, however, they have parts which break more with time. This doesn’t mean you should go for either just based off of that fact but always go for the best option and highest rated on the market with this type of technology so that it would last longer.

If you don’t feel safe with auto ignition, go for the manual types of heaters. If you feel comfortable spending a few more dollars on a safe automatic ignition heater, do so as well, just make sure to never compromise because this little option can make or break the whole place. On one hand, you have the comfort of automated responsiveness from the unit and the technology to keep you safe with the ignition and auto safety. On the other hand, you rely on yourself to manually do these tedious to some tasks, along with the major safety factor to turn the heater on and off. In any case, the best option would always be to go for the proven brands and the most safety a heater can provide, especially if you will be carrying it around with you for most of the time.


When you decide to look for an indoor propane heater consider all the important details we discussed in the buyers’ guide. Know how big of a space you need to heat up and how long you will be spending there. Know your necessities since you might want a portable heater if you want to have it in your shed or when you go camping get something portable and not too heavy to move. Don’t cheap out on safety and good materials and always go for the best quality as it will serve you the longest. Whichever one you choose, this article hopefully helped you make a more educated purchase that you would be happy with.


    • Hi Patty,

      If this occurs when it’s switched on the first time (releasing gas before it is lit) then it’s normal, but if the smell persists when off or on for a period of time you should contact your utility company / installer as it could be a leak on the pipe or heater.

  • Hello, i’m interested in the Avenger Dual Fuel Vent Free Blue Flame Heater, i would like a price on that one, thank you.

  • I am trying to heat an insulated 10×16 shed located at 9,500 feet altitude in the mountains. Do you have any suggestions for a portable propane heater that would work well at around 9,500 feet altitude? I had a portable “Big Buddy” but it did not work at the high altitude, as you point out they shut off at around 7,000 feet. Additionally I would like a heater that is designed to work directly with a an LP tank that is the same size as you typical gas grill propane tank (20LBS), I am making this request because the “buddy” heaters are designed to work with the disposable 1LB LP tanks (which only last about one hour) so if you want to hook them up to 20LB tank you need to buy additional accessories, which I would prefer not to have, I fee extra accessories means more parts to break and necessary complexity. THANK YOU, RPS

  • Are any or all of the mentioned indoor heaters safe to use without outside ventilation, ie window open or door cracked. Trying to heat my man cave/ shop. Just purchased Mr heater 30kbtu, instructions said for outside??? Need specifics PLEASE

    • Hi Drew,

      Even though certified indoor propane heaters do come with several safety measures, you still need to ensure that there is some kind of ventilation in the room to let in oxygen in. Small window open, the door cracked etc.

    • I heat a 10 x 12 shed. Always allow some type of fresh air to enter the room when using propane. Propane heaters consume oxygen, but do not produce carbon monoxide. They are suppose to have a sensor that shuts off the unit if the oxygen in the room becomes too depleted, but it’s not a good idea to trust only the sensors. I once took a nap in the shop and woke up with my heart racing out of control. Fresh air got me back to normal quickly, but ever since then I always leave a window cracked about 5 inches. That’s been working now for several years.
