Best Indoor Propane Heaters in 2021 [Must Read]

During cold seasons, or when there’s a cold weather approaching, it is likely that you’ll want to consider several options to make the colder rooms in your house more comfortable to live in. However, centralized heating may lead to a spike in utility bills and possibly lead to a more severe climate. Hence, a good alternative is to consider indoor propane heaters to keep you warm this winter.

Not only are propane heaters cheaper to run than electric heaters, but they can even easily heat up a room faster. In fact, propane heaters are versatile and portable enough for you to bring along on camping or outdoor use to keep warm.

Considering how useful they are, it is not surprising to find thousands of the best indoor propane heaters available on the market. In this article, we will be looking at the different types of indoor propane heaters as well as how to safely handle them. We also have included a list of our top picks of the best indoor propane heaters for you to consider.

Different Types of Indoor Propane Heaters

There are two types of indoor propane heaters: portable and permanent.

Portable indoor heaters can be easily moved around to wherever you need them to be and they’re also typically smaller in terms of heating capability. Portable indoor propane heaters are normally used to supplement an existing heating system which may be inefficient to warm certain spaces in the house by itself.

Portable indoor propane heaters are also great for providing heat while camping or during a power failure. However, they generally do not provide extra ventilation.

Permanent indoor propane heaters, on the other hand, are usually mounted to a wall in the home and are attached to a larger fuel tank located outside the home. Storage tanks are fixed in place and filled by delivery trucks as and when required. The good thing about these permanent heaters is that they’re larger in heating capacity compared to a portable model.

Permanent indoor propane heaters are also designed to heat a bigger room or even an entire house. Most models employ a circulation fan inside the heater to better distribute warm air where needed. And because of their size, these heaters do produce a larger volume of exhaust gas that must be vented outside the house for safety purposes.

Comparison Overview – Propane Heaters vs Kerosene

While comparing fuel types for indoor heaters, you need to keep in mind the efficiency as well as the cost of the fuel being used.

Kerosene is known to be highly combustible that produces a lot of heat whereas propane burns very effectively and provides a clean source of heat. Although kerosene is more efficient than propane heaters, the latter is much cheaper and makes up for the difference in terms of efficiency.

Other than that, propane can also be used in a closed room or tent for heating since it does not emit any soot or smoke thanks to its low carbon content. Kerosene, on the other hand, has higher carbon content than propane and produces a lot of fine particles. Some of the compounds include carbon monoxide and sulphur dioxide.

Indoor Propane Space Heater vs Electric Heaters

The major difference between propane heaters and electric heaters is their heating source. As the name suggests, propane heaters use propane fuel whereas electric heaters use electricity. Propane heaters or gas heaters can seldom be used in a completely confined place with no air outlet whereas electric heaters can be safely used in a closed space.

Another significant difference between the two indoor heaters is the cost price and running price of these appliances. While electric heaters are cheap to buy, they’re very expensive to run since they rely on electricity. Propane heaters or gas heaters have a higher cost price but are cheaper to fuel in the long run.

Safety Features to Consider when Buying the Best Indoor Propane Heater

Indoor heaters typically involve the use of dangerous and poisonous gases and other emissions, hence it’s important for them to come with several additional safety features. Because of the need for these safety improvements, it is critical that you never use outdoor propane heaters indoors, not even for a short period of time. You must check that all indoor propane heaters are certified for indoor usage.

While the safety features offered by each manufacturer will differ, most of them will have a few common features. All indoor propane heater models include tip protectors that will extinguish the flame if the heater gets accidentally knocked over. Another safety feature is the oxygen depletion sensor (ODS) that automatically shuts off the heater when it detects that the oxygen in the room falls below a safe level.

Most will also have an overheat protection that will instantly turn off the burner and gas when the unit overheats or when the propane gas continues to flow in while the burner is inactive. Another nifty innovation is the one-hand piezo ignition that lets you not have to bother with lighting up the pilot whenever you want to use the heater. All these protections will help make the best propane heaters safer for indoor use.

How to Light Indoor Propane Heaters

Already bought a suitable propane heater for your home but not sure how to light one up properly? Here are a few common steps you will need to do to light up your indoor propane heater to keep warm:

  • Ensure that the supply lien is well-placed and hooked up with your heater with no leakages.
  • Check the heater’s igniter that is required to light up the pilot as well as the incoming gas from the valve
  • Turn on the supply line valve and turn the knob at the heater’s upper side to pilot mode. Once in pilot mode, you’ll need to keep pressing the knob for 20 seconds. This may take longer if the propane heater has not been used in a while.
  • Turn the knob counterclockwise to your desired temperature and the heater will automatically light up

Safety Tips

While operating a propane heater or space heater is rather safe to use, there are a few steps you can take to ensure better safety. The first thing you can do is to ensure ventilation by cracking open a window. Though this may seem strange since you want to heat up the place, you also need to make sure to avoid filling up the room with poisonous gas, especially if you plan on staying in it for long periods of time.

High levels of carbon monoxide released from a propane space heater can be fatal. Early signs of carbon monoxide poisoning are similar to flu symptoms like a headache, dizziness, and nausea. If you’re feeling these symptoms and suspect that your space heater is not working properly, it is best for you to get some fresh air right away.

Another safety tip is to check for gas leaks regularly. Every time you connect your heater to its fuel supply or propane tank, do take note to check the connection points and hoses for any damage and/or potential gas leaks. If you’re able to smell gas, try applying soapy water to the connections between the hoses, unit, cylinder, and propane tank to inspect for bubbling.

Aside from that, you can also carefully listen to the hiss of gas escaping and touch the cylinder to feel for extreme cold. If you suspect the connection or cylinder is leaking, make sure you do not light up the space heater as it needs to be replaced as soon as possible.

When running propane space heaters, you need to keep them out of reach of pets and kids and well away from foot traffic. Place it away from flammable materials and do not store extra LP or propane tanks near the heater while the propane space heater is in use (fuel cylinders must always be stored outside). Also, make sure that your propane space heater is not too close to your carbon monoxide detector to ensure a more accurate reading.


The best propane heater should be both convenient and effective for heating up the colder spaces in your home. Whether you’re planning to heat up your garage or to stay warm on a camping trip, a portable propane heater will certainly come in handy.

Do keep in mind that indoor propane space heaters need to have several essential safety features to ensure safe use indoors. This is critical to prevent gas leaks, carbon monoxide poisoning, and overheating. Always ensure that the propane space heater you’ve purchased is rated for indoor use. In case you’ve not found the perfect propane gas heater for your house, you can consider our top picks above as they’re proven products that will deliver great performance as the perfect heater for indoor purposes.

Frequently Asked Questions

How much propane does a propane indoor heater use?

The amount of liquid propane that space heaters use will depend on the heat settings you’re using for your heater. A gallon of propane gas has a burn rate of approximately 1,000,000 BTUs, meaning if you run a heater at 30,000 BTUs, you can expect your propane to deplete by ⅓ part of gallons per hour.

Do I need electricity to run an indoor propane space heater?

No, no electricity is needed in a propane heater. Most propane space heaters are completely reliant on propane gas as fuel and do not require additional electricity to work.

How does a vent-free propane heater work?

Ventless propane space heaters do not require a vent to take in air from the outside for combustion purposes. Instead, they use the air from their surroundings. Propane produces clean heat and no by-products while burning, so no vent is needed to expel any dangerous gases.

Are propane heaters efficient?

Yes, propane heaters are indoor-friendly, however, you need to check the properties of each heater and ensure it’s rated for indoor use. Propane space heaters indoor come with an automatic low oxygen depletion sensor and an automatic shut-off feature to ensure user safety.
