Different Styles of Indoor Propane Heaters

Indoor propane heaters come in two types: portable and permanent. Portable heaters can be moved easily to wherever needed and are typically smaller in heating capability. They are normally used to supplement an existing heating system which may inefficiently warm space in the house.

Portable indoor propane heaters are also great for providing heat while camping or during a power failure. Indoor portable heaters generally don’t have extra ventilation.

On the other hand, a permanent indoor heater is usually mounted to a wall in the home and is attached to a larger tank of fuel that is located outside the home. The storage tanks are fixed in place and filled by a delivery truck. These permanent heaters are larger in heating capacity than a portable model.

They 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.

Safety Features to Look Out for When Buying an Indoor Propane Heater 

Because of the danger of poisonous gases and other emissions, indoor heaters have several additional safety features. They are 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.

While the safety features offered by each manufacturer will vary, some of them are common in all of them. All models of indoor heaters include tip protectors that extinguish the flame if the heater is knocked over.

Another safety feature is the oxygen depletion sensor (ODS) that shuts off the heater when the oxygen in the room falls below a safe level. 

Overheat protection is a feature that will instantly turn off the burner and gas when the unit overheats. Or if the gas is flowing in while the burner is inactive. Another nifty innovation is one hand piezo ignition, which means you don’t have to bother with lighting up the pilot whenever you want to use the heater. These protections help to make them safer for indoor use.

Comparison Overview 

Let's have a brief comparison between some popular heaters and the fuels used.

Indoor Heater Propane vs. Kerosene

While comparing fuel types, we must keep in mind the efficiency and the cost of the fuel being used. 

Kerosene is a highly combustible substance that produces a lot of heat. On the other hand, propane burns very effectively and provides a clean source of heat. 

Although kerosene is more efficient than propane, the latter is much cheaper and makes up for the difference in efficiency. 

Propane can be used in a closed room or tent for heating since it emits no soot or smoke due to its low carbon content. Kerosene has higher carbon content than propane and produces a lot of fine particles. Compounds such as Carbon Mono-Oxide and Sulphur Di-Oxide are also a combustion product. 

Propane Space Heater Indoor vs. Electric

The major difference between propane and electric heaters is the use of propane and electricity. Propane or gas heaters can seldom be used in a completely confined place with no air outlet. Contrary to this, electric heaters can be used in a closed space.

The other significant difference is between the cost price and the running price of these appliances. Electric heaters are cheap to buy while very expensive to run; this comes as no surprise because they rely on electricity. On the other hand, gas heaters have a higher cost price but cheap fuel.

How to Light an Indoor Propane Heater

Not sure how to light an indoor propane heater properly? Here is what you need to do:

  1. First of all, make sure that the supply line is well-placed and hooked up with your heater, and there are no leakages. 

  2. Next, check the heater's igniter that is needed to light up the pilot and the incoming gas from the valve. 

  3. Turn on the supply line valve and then turn the knob at the heater's upper side to pilot mode. Once in the pilot mode, you need to keep pressing the knob for 20 seconds. It may take longer if the heater has not been used in a while. 

  4. Turn the knob counterclockwise to your desired temperature, and the heater will light up.

Safety Tips For Handling Indoor Propane Heaters

Ensure ventilation by cracking open a window.  It may seem strange to open a window when you’re trying to heat up the place, but you have to avoid filling the room with poisonous gas.

High levels of carbon monoxide can be fatal, and the early signs of poisoning are similar to flu symptoms: a headache, dizziness, and nausea.  If you’re feeling these symptoms and suspect the heater isn’t working properly, get some fresh air right away.

Check for gas leaks regularly. And every time you connect your heater to its fuel supply, check the connection points and hoses for damage and/or any potential gas leaks. If you smell gas, try applying soapy water to connections between hoses, the unit, and cylinder, and inspect for bubbling.

Carefully listen for the hiss of gas escaping, and touch the cylinder to feel for extreme cold.  If you suspect the connection or cylinder is leaking, do not light the heater—it will need to be replaced.

When running the heater, keep it 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 cylinders near the heater while it’s in use (fuel cylinders should always be stored outside).  Also, make sure it’s not too close to your carbon monoxide detector for a more accurate reading.


Propane heaters are both convenient and effective for heating up the colder spaces in your home. Whether it’s a project in your garage or you need to keep warm on a camping trip, a portable propane heater will come in handy for sure.

Keep in mind that indoor propane heaters need to have essential safety features. To prevent gas leaks, carbon monoxide poisoning and overheating. Always ensure that the heater you purchase is rated for indoor use. In case you’ve decided to go for a propane gas heater, consider our top picks above for proven products that will give a great performance.

People Also Ask

If you’re on the hunt for good indoor propane heaters and need some guidance on their safety and installation, then this is the right place for you. Some of the most frequently asked questions are listed here along with their answers, in order to clear your ambiguities. 

How Much Propane Does an Indoor Propane Heater Use?

It depends on the heat settings that you are using for your heater. A gallon of propane gas has a burn rate of around 1,00,000 BTUs. This means that if you run the heater at 30,000 BTUs, it will deplete 1/3 part of gallons per hour.

Do I Need Electricity to Use an Indoor Propane Heater?

Most propane heaters are completely reliant on gas as a fuel and don't require any additional electricity to work. So, no electricity is needed in a propane heater.

What is a Tank Top Propane Heater?

These heaters don't require any supply line connection for the propane input. They have built-in tanks at the lower part of the heaters that are filled with propane. They can also store propane for future use or during emergency conditions. Dual-tank top heaters are also currently available in the market.

How Do Vent-Free Propane Heaters Work?

Ventless heaters don't require a vent to take in air from outside for combustion since they use the air from their surroundings. Propane produces clean heat and no by-products during its burning, so no vent is needed to expel any gases.

Are Propane Heaters Efficient?

Propane heaters are highly efficient as compared to electric heaters. They can provide up to 99.9% efficient results. Not only this, but they are much cheaper to use than electric heaters.

Are Propane Heaters Safe to Use Indoors?

Propane heaters are used both indoors and outdoors, but they are both different types, and you need to look into the properties of each heater to determine if it is indoor-friendly. Indoor propane heaters have an oxygen depletion sensor and an automatic shut-off feature to ensure user safety.

Do You Need Ventilation When Using a Propane Heater?

Yes, you do need ventilation while using a propane heater because it consumes oxygen and emits heat using oxygen. If the oxygen level is low or finished, it starts emitting carbon monoxide, which is poisonous to the lungs and fatal for humans. 

Do Propane Heaters Give Off Carbon Monoxide?

When propane gas is fired, it starts breathing oxygen to produce heat. This, in turn, consumes all the available oxygen in the given space, and if the oxygen is fully consumed, and ventilation is not provided, the heaters start giving off carbon monoxide, which is harmful to living things.

Can Propane Fumes Harm You?

Breathing in propane fumes can give you oxygen deprivation and lead to symptoms such as dizziness, nausea, drowsiness, and confusion. They can mess up your brain nerves and even cause brain damage and death. Hence, propane gas, if inhaled, is extremely dangerous and can lead to death in some cases.

Is it Safe to Run a Propane Heater in my Garage?

Yes, it is safe to run a propane heater in the garage as long as you keep it away from highly inflammable items and provide it enough air and ventilation in the room to not radiate toxic gases such as carbon monoxide. It's also recommended to install a CO detector as a safety measure.
