What is a portable propane heater?

A portable propane heater is exactly what it sounds like. In essence, it is a small heater that can be easily moved and relies on propane as its main fuel source. Propane, if you don’t know it, is originally a flammable gas that is produced as a by-product of fracking and similar procedures designed to collect natural gas.

Propane is produced in abundance and is important as an inexpensive fuel source for the average individual. When it appears as a by-product, it transforms from gas to liquid and is stored in special containers to prevent fires. When propane is connected to a device, it is converted from a liquid to a gas and is usually ignited to create a fire that releases energy in the form of heat.

It is important to note that there are a variety of propane containers and the heaters use different ones. Be sure to read the instructions that accompany any portable propane heater to purchase the correct product and stay safe.

How does a propane heater work?

Propane heaters work in a number of ways. However, the main premise is that the liquid propane that is kept in its sealed tank is then transformed back into gas, where it can be ignited to create a fire or used to heat an internal filament within the machine. In addition to this basic premise, propane heaters can be classified according to the scientific principle that they use to transfer heat. Most are considered radiant or convective.

Radiant propane heaters follow the basic premise of thermonuclear energy transfer. This may sound a bit confusing, however it means that the device follows the same principles as the sun. Energy can appear as radiation. Not dangerous nuclear radiation, but the movement of wavelengths through space.

In a radiant propane heater, propane is used to generate heat that is transferred through radiation to objects instead of being carried through the air and the environment.

Propane convection heaters follow the scientific principle of convection. This should sound like a familiar process to anyone who has seen soup cook or studied lava. Basically, the principle states that cold gases and liquids sink while hot liquids rise.

In a convection heater, the device draws air into the machine and forces it over a heated surface or filament. As the air heats up, it rises to a separate section of the device and is then released or blown back into the room. This keeps the atmosphere moving and helps keep a room warm.

In addition to radiant and convection heaters, you may have heard of forced air options. Forced air heaters typically use radiant or convection heating. The forced air portion of the heater refers to the amount of air that comes out of the machine after it has been heated. Forced air heaters are designed to cover large areas, so they should NEVER be used indoors. It’s too easy to overheat in that scenario and potentially cause a fire.

Buying Guide For The Best Indoor Propane Heater

As you may have observed, there are a couple of properties that are repeated for each product but have a different value, such the size, heating capacity, portability, etc. To get the most suited product for your job, you need to analyze all of these features and get the most optimum option for yourself.

As it is not a very easy task, we are helping you with that via our buying guide given below. This buying guide contains each of those important parameters and their necessity regarding various applications. Hence, you can easily prioritize the features that you need the most and get the perfect heater accordingly. Therefore, we will suggest you read the buying guide completely before finalizing your purchase. Here are the key aspects of an indoor propane heater that should keep in mind before buying one:

1. Overall Heating Capacity

As the main aim of an indoor propane heater is to heat up a room, the heating capacity plays an important role. The heating capacity is generally given in the BTU, generally known as the British thermal unit.

In our list of the best indoor propane heaters, you can find the heating capacity varying from 8000 BTU up to 68000 BTU. Hence, there is certainly one or two options that are best suited for your needs. Also, make sure you consider the heating area as well as that also affects the heating capacity.

2. Size – portable propane heater

The size is an important factor as it is an indoor device. Similarly to many indoor devices, you should be considering as compact a device as possible as it saves a lot of space in the room and does not clutter your storage area.

But, the smaller devices generally lack power. Hence, you need to go with a bigger option if you require a higher power output. Therefore, before confirming your choice, make sure you check out the power requirement as well as the space available in the room to get a perfect size.

3. Portability

The portability becomes a necessary feature if you wish to use the indoor propane heater in several different locations. There can be different locations inside the same house, such as a living room, sleeping room, kitchen, etc. Or, you might have to carry it around on your job site for a controlled work environment.

You can also look at it as a heating device for camping if you are planning a trip in cold weather. The portability is largely affected by the size and weight of the heater. A large-sized device will not fit, whereas a heavier option will be difficult to carry.

4. Reliability – portable propane heater

An indoor propane heater consists of many critical parts that can fail and make the entire heater incompatible or straight up useless. To make sure your indoor heater does not fail for a long time, you need to confirm its reliability.

The reliability is largely dependent on the build quality and the quality of parts used for manufacturing the heater. As it is not possible to check the durability of each part physically, you can simply take a look at the warranty period allotted by the manufacturer. In this warranty period, you can get the failed parts repaired or even replaced for free of cost.


A decent indoor propane heater can be a lifesaver in terms of providing warmth and comfortable sleep in the cold nights of winter. You will not find anything more relaxing than a warm, open fire in the winter. The indoor propane heater will give you a similar experience with much less investment and with a high safety factor. As there are many options available for a propane heater, it can get a little confusing while choosing one option amongst all.

Hence, we have drafted this article about the best indoor propane heaters on the market. You can read about the indoor propane heaters and easily decide which one is the best option for you. We are also providing a buying guide to help you along the process. But, here are our top recommendations in case you want a little extra help in deciding the perfect option:

  • Flirt, we will recommend you the Dura Heat propane heater as it is marginally affordable as compared to other options from our list. Even at the cheaper piece tag, it offers up to 1000 square feet. It is also the most portable option on our list as it weighs only 4 lbs, excluding the propane tank.
  • Although, if you are looking for a heavy-duty option, then the Dewalt propane heater is the best option for you. With a huge heating capacity of up to 68000 BTUs, it can be easily used for any professional work. It is backed by 2 years of warranty from Dewalt.
