This heater runs up to 3 hours before needing a refill and includes a protective cover for safety purposes. You can use it in your house, tent, or anywhere outside.

Throughout this article, you’ll also learn the following details about the best portable propane heaters:

  • The seven top choices on the market
  • What you should watch for when shopping for a new portable propane heater
  • How to get the best propane heater for various uses

What To Look for When Buying a Portable Propane Heater

While looking for the best portable heaters on the market, I noticed three essential features that separated the top-notch choices from the rest of the pack. It wasn’t their appearance or noise level. Both traits are important, but propane heaters are relatively quiet and look quite similar. 

The three crucial features that brought the seven heaters to the top are as follows:

  • BTUs (British Thermal Units) and square footage capabilities
  • Overall cost-effectiveness
  • How long the heater runs before it needs a refill

These traits drastically influence buyer’s decisions and positive customer feedback. It’s impossible to get a high-quality portable propane heater without recognizing how impactful they are. The good news is I’ve broken down each of them below to help you better understand why they’re so crucial.

BTUs and Square Footage

British Thermal Units are a unit of heat. More BTUs result in higher heat, while lower BTUs reduce the output. Remember, you don’t always need to reach for the highest BTU heater. In some cases, it can be detrimental and burdensome. For instance, if you have a small 250 sq. ft. (23.2 sq. m.) room and you get a 20,000 BTU heater, it’ll overheat quickly.

You should base your BTU buying decision on the square footage of the room you want to heat. Also, more BTUs typically heat up faster than low-BTU portable propane heaters. There’s a sweet spot to ensure you’re getting the most bang for your buck without overheating or underheating the building.

So, how are you supposed to know how many BTUs you need? Review this table for a detailed breakdown:

BTU (Units of Heat)Square FootageOperational Duration
6,000 BTUs2001 Hour
12,000 BTUs4001 Hour
18,000 BTUs6001 Hour
24,000 BTUs8001 Hour
30,000 BTUs1001 Hour

Sources: We Love Fire, Calculator.net

It’s important to remember the operational duration is heavily influenced by your home’s insulation, whether the doors and windows are open or closed, how many people are in the room, and many other factors. Carpets hold heat better than tiles, and skylights can affect the ambient temperature, too.

There are many variables, which is why the operational duration remains the same for all BTU and sq. ft. calculations. According to numerous sources, the BTU specified above corresponds with the square footage for a one-hour turnaround. However, your home or room might experience different reasons based on the previously mentioned conditions.

With this knowledge in mind, you can choose the best portable propane heater for your home. Square footage and BTUs are crucial, so make sure you calculate the dimensions beforehand. Most blueprints will show how many square feet are in each room, but you can multiply the Length x Width to get the square footage.

Take the equation a step further by using this calculator to factor the ceiling’s height and a few other dimensions for a perfect fit.

Cost (Maintenance, Initial Purchase, and Refills)

Perhaps the first thing you’ll notice when buying a new portable heater is the price. We all love to save money, but it’s important to keep in mind most high-quality heaters cost more but last longer. Fuel efficiency is another trait worth noting. Let’s break everything down below to paint a clearer picture.

  • The initial purchase price will be the highest number. You’ll likely have to spend over $50 to get a decent heater, though there are a few exceptions. For a top-of-the-line model, you’re looking at $100 or more. Keep in mind these prices fluctuate and grow over time, but they’re reliable nevertheless.
  • Propane costs about $2.00 to $4.00 per gallon. Your propane heater needs to have excellent fuel efficiency to last a few hours or more. Using a large 20-gallon (75.7-liter) propane tank will keep your heater running for a long time. Some heaters come with reservoirs. According to Home Advisor, propane refill stations top at 80% capacity for safety purposes.
  • Maintenance costs depend on the heater’s quality. Some of them come with warranties, which can save you tens or hundreds of dollars. If your portable heater has a high-heat rating, it can withstand countless issues and last many years without too much maintenance. Clear debris, clean the fuel tank, and inspect the internal components annually.

Run Time Duration

The run duration isn’t the same as the operational duration. When we’re referring to the operational duration, it’s how long the heater needs to run to heat the room. As you hopefully read earlier on the page, it takes about an hour for an efficient propane heater to get the job done. The run duration relates to how long a heater can operate before needing more fuel.

There are two features that influence a propane heater’s run time duration:

  • Fuel tank size: Some propane heaters have a one-gallon (3.8-liter) tank, and others mount on top of a 20-gallon (75.7-liter) tank. More fuel equates to a longer run time duration, which is crucial for long-term use. It’s not too big of a deal if you’re using the heater a couple of hours per week, though.
  • Fuel efficiency: The burn rate is impacted by clogs, filters, and other features. Most portable propane heaters burn at the same rate. Santa Energy shows the burn rate is changed by the BTUs. High-BTU heaters burn quicker than low-BTU heaters.
