Top 10 Smallest Propane Heater – (Reviews & Guide 2021)

Propane prices have been on a downtrend recently. According to multiple sources, including YCharts, prices are down about 1.08% compared to the same time last year.

This is excellent news considering that markets projected the prices to go up following the Covid19 stay-at-home.

Overall, the prices are expected to remain stable throughout the year and, barring unforeseen events, throughout 2021.

For this reason alone, if you’ve been thinking about getting that extra space heater for your home, a small propane heater would make perfect sense.

The rest of this guide is designed to help you evaluate low-capacity propane heaters to determine the one that best suits your needs.

Let’s begin by reviewing some of the best small propane heaters. We’ve picked these units based on performance (BTU output), convenience features, and safety features, among others.

Smallest Propane Heater

What’s a Propane Heater?

Propane heaters are space heaters that generate heat by burning propane fuel. The fuel is contained in a tank and can be ignited using automatic or manual ignition. Propane typically exists as a gas. However, when used in heaters, it’s compressed into a liquid.

Most propane heaters employ what’s known as piezoelectric ignition. A material, often quartz crystal, with the property to develop electric potential when pressure is applies is housed in a mechanism that allows striking using a spring-loaded hammer.

This action sparks the material, generating a flame. An element within the heater, often porcelain, spreads the flame out in a pattern and evenly disperse the heat.

Something else that even the smallest propane heaters have is a pilot light. The pilot light is a small flame designed to light the main burner relatively quickly rather than illuminate the unit from scratch. It burns pretty much continuously, though it doesn’t use a lot of fuel.

Benefits of a Propane Heater

We’ve already mentioned the low fuel prices. What you may also want to know is that propane is a lot cheaper than electricity. Some studies report that you can save up to 30% on your heating bills per year. Aside from the running costs, propane heaters stand out for the following reasons;

  • Propane heaters are extremely versatile: The smallest propane heaters can be used practically anywhere inside the home. You can buy one for the basement and use it in the garage, barn, etc., without any challenges.
  • Propane is a very safe gas: Propane cylinders are 20x more puncture-resistant than gasoline, ethanol, and methanol containers. If there’s a leak, the added odorant makes it easy to detect it and act appropriately.
  • It’s an invaluable tool in emergencies: In an emergency where your electricity is knocked out, propane heaters can be a life-saver. Since they don’t need electricity to function, you can conveniently use the propane heater until the power returns.
  • Propane is a high-energy gas: Propane has a higher octane rating than the gas you use in your car. Also, propane heaters can produce and maintain heat levels closer to over 115°F, which is much higher than electric heaters that keep the air around body temperature.
  • Environmentally friendly: Finally, propane is very environment-friendly. It burns cleaner than any fossil fuel and doesn’t contaminate groundwater or soil. It also has a low carbon content, thus produces minimal emissions.

Propane vs. Electric vs. Natural Gas Heaters

A lot of people shopping for propane heaters like to compare them with electric and natural gas models. How does propane compare to the other two fuel sources and, in the end, which is the best out of the three energy sources?

Propane vs. Natural Gas Heaters

Let’s begin by comparing LPG with its close cousin – natural gas. The first thing you need to know is that propane is the purer of the two fuel sources.

While natural gas comprises several gases, including butane, ethane, and methane, propane is separated from these other gases. Remember that natural gas also contains substantial amounts of propane.

Secondly, concerning heating power, propane is also more potent. One cubic foot of propane produces about 2,516 BTU, whereas a cubic foot of natural gas only generates around 1,030 BTU. This makes propane at least twice as powerful.

The only area where natural gas triumphs is pricing. It’s not easy to compare the prices since propane is measured in gallons while natural gas is measured in cubic feet. However, you’ll usually pay around 4x for propane than natural gas to generate the same amount of heat in BTUs. 

Propane vs. Electric Heaters

Propane is, however, cheaper than natural gas. You’ll pay about twice as much to get the same level of heat from an electric heater compared to a propane heater. Some studies even suggest that in the end, propane heating is 3x less expensive than electric heating.

Another critical difference between the two is the degree of warmth. As mentioned earlier, propane heaters can keep the home at over 115°F (most maintain indoor temperatures at 130-140°F). An electric heater, by comparison, can only maintain indoor temperatures at around 98°F.

Finally, propane is also more dependable. We’ve mentioned that these heaters can step in during emergencies. Another thing is durability. On average, propane heaters last 5-10 years longer than their electric counterparts.

Interestingly, electric heaters are even more common than propane heaters. The two main reasons are prices and maintenance. Electric heaters are more readily available and much cheaper than their propane counterparts.

The smallest electric heaters cost under $50, while you need at least a few hundred propane heaters. Electric heaters are also practically maintenance-free.

Are Propane Heaters Safe for Indoor Use?

This is a question a lot of people ask, given that propane is a hydrocarbon. The answer is – yes. But, only if the heater is used correctly.

Otherwise, there’s the risk of;

Carbon Monoxide Poisoning

According to the U.S. government, there are at least 15 carbon monoxide poisoning incidents related to propane or natural gas in the country. This might not seem like a big number, but it tells that carbon monoxide positioning is a real possibility when using propane heaters.

Fire Explosions

Propane leaks can also cause fire explosions. Although these incidents aren’t as many as CO poisoning cases, a propane related fire is still reported about every other day within the country, according to the U.S. government.

Propane Heater Safety Tips

Fortunately, you can significantly reduce the chances of propane leaks, thus preventing related poisonings and fires. Consider the following tips;

  1. Use indoor-rated heaters indoors: Never use an outdoor propane heater indoors if the manufacturer doesn’t say it can be used indoors. The reason is that some outdoor propane heaters are safer outside because of unlimited ventilation. There isn’t as much ventilation inside the house.
  2. Choose the right-size heater: It makes little sense buying a 60,000 BTU propane heater for your small reading room. Moreover, it creates an unnecessary safety risk. Instead, determine your heating needs in BTU and buy a heater that isn’t too far from that figure.
  3. Always install an ODS: An Oxygen depletion Sensor (ODS) tracks oxygen levels in your home and alerts you if dangerously low levels of O2 are detected. Even if the heater has a built-in ODS, it helps to install the second one if the in-built sensor fails.
  4. Use the heater away from combustible items: A vital advantage of the smallest propane heaters is that they can be carried along everywhere you go. Just make sure that the heater isn’t placed next to flammable materials, such as curtains, furniture, bedding, and towels.
  5. Never leave the heater ON unattended: This is what causes most fires. Turn off the heater when you leave the room. You can turn it back on when you need it. Also, always check that the heater is off before you go to sleep.
  6. Take care to prevent tip-overs and overheating: A small propane heater on the table can be toppled or knocked over, creating a fire risk. The heater can also get extremely hot during operation. Choose a heater with built-in mechanisms to address both problems.
  7. Look out for safety approvals: Finally, a safe propane heater is one that’s been tested and approved by recognized agencies such as the Underwriter’s Laboratory (UL) and Intertek.

Other Factors to Consider When Buying a Small Propane Heater

You’ve decided that you want a small propane heater, and we’ve also discussed the safety considerations. So, what else should you look out for when shopping?

What size?

Small can mean anything from 1,000 BTU to 12,000 BTU. What size, exactly, would be ideal for your application? The rule of thumb is to get 30-60 BTU per square foot.

Ideally, you want to stick around the 30-40BTU/square-foot mark unless you’re shopping for a propane heater for poorly insulated spaces such as the basement or garage.

Mounting Type

Small propane heaters can mount on the wall or ceiling or stand on the floor. The ideal installation option will depend on, among other factors, the intended application.

Are you buying it for patio use, the basement, or the barn? Make sure you select an installation type that guarantees safety during the application.

Fuel Efficiency

Propane heaters are some of the most energy-efficient. Many convert 90% or more of the fuel into useful heat, losing only 10%. However, that doesn’t stop you from hunting for the most efficient model. To this end, consider the Annual Fuel Utilization Efficiency (AFUE) rating. A higher AFUE means a more efficient heater.

Style and Other Features

Finally, the best propane heaters are fitted with multiple convenience features to make your work easier. A few things to consider include handles for easy mobility and overfill protection device (OPD). A built-in thermostat and multiple heat settings are also worth considering.
