The best propane heaters can keep you warm, whether you’re in the woods or the woodshop. By connecting to a propane fuel source––be it a portable one-pound canister or a 100-pound tank––propane heaters emit warmth by burning the gas and projecting the resulting heat. Some units rely on metal reflectors, while others produce radiant heat that travels through the air like the sun’s rays. Fans help circulate the warmth in forced-air units. They also serve as emergency equipment in the event of a power outage.

Propane heaters can be small, portable burners that sit atop camping canisters, or they can be larger standup units that create a warm ambiance on your patio or deck. Many people prefer them to kerosene heaters, which are cheaper to operate but require use and storage of kerosene. Some vent-free propane heaters, which are safe for indoor use, mount directly to your wall. Propane heaters burn very efficiently, but they still can emit carbon monoxide if there’s an incomplete burn caused by a lack of oxygen in a space that isn’t ventilated. That also means they can be dangerous, even when approved for indoor use. Many of the best propane heaters feature oxygen depletion sensors that will automatically shut off the unit when the oxygen levels in the room dip too low. 

Clearly, there is a lot to consider when shopping for the best propane heaters. But hopefully we can ignite your search and guide it in the right direction for your needs.

How We Chose The Best Propane Heaters

As outdoorsmen and women, we often find ourselves using heaters to stay warm. Whether on a winter ski trip to a remote cabin or hanging on the patio during the cool fall months—staying warm is not only critical for safety, but also for enjoyment. After spending a lot of time outside and around heaters we’ve come to focus on some key components when selecting a quality propane heater. We based our picks on the following criteria: 

BTUs: How powerful is the heater?
Rate of fuel consumption: How fast does the heater burn fuel?
• Square footage of space the propane heater can warm: What size area can the heater warm?
Size: How large is the heater and how much room do you need to use it?
Weight: How heavy is the heater and is it portable?
Mounting options: Can the heater be mounted on a wall or accessory?
Safety precautions: Does the heater have automatic shutoffs that can be triggered in response to the heater tipping, or low oxygen levels?

Things to Consider Before Buying The Best Propane Heaters

Here’s what to consider when shopping for the best propane heater:

What type of propane heater are you looking for?

Propane heaters can be small enough to fit into the cupholder of a golf cart or sit atop a picnic table, or they can be larger permanent units that mount onto a wall. Patio heaters stand tall and give off heat in every direction, while portable outdoor heaters are ideal for boats or hunting blinds. Some propane heaters have forced-air systems that use fans to blast hot air produced by burning propane, while radiant propane heaters have elements that give off heat much like the sun and use reflectors to help guide the warmth. Convection heaters circulate air through heating elements, taking advantage of the density differences between hot and cold air to keep the heater constantly energized. Convection heaters are typically the most energy efficient, but they can also be more expensive. Many patio units or portable propane heaters use radiant heat, warming you much like the flames of a campfire. 

Are the BTUs right for you?

A propane heater’s energy output is measured in British Thermal Units (BTUs), and propane heaters can span from roughly 3,000 BTUs to more than 40,000. Generally speaking, the higher the BTU count, the more warmth a propane heater is capable of producing, and thus the larger the area that it can heat. However, powerful patio heaters have tens of thousands of BTUs, but they are not safe for indoor use, so the area of warmth is diminished as the heat dissipates in the open air.   

What size of propane tank will you need?

Propane heaters are not one-tank-size-fits-all. Some units require connections to large 100-gallon tanks, while smaller portable propane heaters can attach to 1-pound canisters. Many of the best propane heaters can connect to a common 20-pound gas-grill propane tank. 

Beyond the size of the fuel tank, it’s important to pay attention to a propane heater’s burn rate. Some propane heaters will drain a 20-pound tank in less than 10 hours, while others can stretch that by several hours. If you need more sustained heat rather than more powerful heat, the latter option may be right for you.

What is the ignition system?

Most of the best propane heaters feature automatic electric starting systems that allow you to press a button to ignite the heating element. But some models require manual ignition. Automatic Piezo starters work by placing a crystal between two metal plates. When you push the button, you move the crystal, allowing the charged plates to spark. Such systems are designed to last for more than 20,000 starts. Manual ignition will work as long as you have matches or a lighter, and propane in the tank.

Can you turn up the heat?

Being able to dial the temperature up or down is important both for comfort and fuel conservation. Some propane heaters have specific settings that let you select your exact BTU output, while others work more like an unmarked dial on a gas stove.

What safety measures are in place?

While propane is an efficient source of energy, burning it can produce potentially dangerous carbon monoxide if combustion is incomplete due to low oxygen levels or a malfunctioning unit. (The state of California bans indoor vent-free units). But the best propane heaters are equipped with oxygen depletion systems that will automatically turn the heater off when nearby oxygen levels are too low. Other propane heaters will turn off if a leak is detected, preventing you from flooding an enclosed space with propane. Other units have tilt sensors that shut off before the heater falls. Such safety measures are critical if you plan to heat an indoor space, though some sensors can be too sensitive for some user’s tastes. 


Q: How much do propane heaters cost?

Propane heaters cost anywhere from $50 for portable units to more than $500 for standup heaters suited for the patio.

Q: What propane heaters are safe to use indoors?

Propane heaters that are vent-free are safe to use indoors. Such units pull oxygen from the room and emit heat and carbon dioxide. This heating process is extremely efficient, but it can be dangerous if there is not an adequate supply of oxygen in the area. That results in incomplete burning, which results in carbon monoxide emissions. Many of the best propane heaters feature oxygen depletion sensors that will shut the unit off as soon as oxygen levels in the room are too low, or if the pilot light goes out. Properly installed carbon monoxide detectors in your home can also help keep you safe.

Q: Do propane heaters work?

Propane heaters absolutely work. Ignition, either through an electric starter or a match, reacts with flowing propane gas to produce radiant or blowable heat. The best propane heaters can warm outdoor spaces or can even be used to heat homes of more than 1,000 square feet.

Q: Does propane get too old to use?

No, propane does not get too old to use. As long as your tank is completely air-tight, propane fuel has no expiration date. Tanks, however, may be compromised after more than a decade. Look for signs of deterioration such as rust or corrosion.
