10 Best Propane Burners for Homebrew Kettles

By Matt Giovanisci •  Updated: 06/22/18 •  12 min read  •  Gear

So you’re done with small batches on your stovetop. Or maybe you’re jumping into homebrewing as way to get good beer and spend more time outdoors. Or waiting for your massive kettle to boil is slowly draining you of your sanity. Whatever your reason, you find yourself in need of a good propane burner.

You can find a good burner online, at your local camping or hardware store, and even at homebrew supply outlets. But how do you find the best propane burner for your homebrew kettle? You just need to understand what to look for, and how to get started if you’re new to burners.

Best Propane Burners for Homebrew Kettles

Why a Propane Burner? Why Not a Campfire?

Theoretically, you could suspend your brew kettle over a cozy campfire and brew your beer the way they did in the Middle Ages. While that might be a fun experiment for a medieval ale recipe, the problem is, you won’t be able to control the flame or the heat.

A propane burner gives you that control so you don’t have a wort boilover, and there are no messy ashes to clean up afterward. Plus, it burns much cleaner than wood, so it’s better for the environment. It’s an all-around win-win.

Getting Started with a Burner

If you’re looking for a way to cut down on the amount of time it takes to get a big kettle boiling, a propane burner is the way to go. But these burners are finicky and take some serious practice.

Once you have a burner, carefully read the instruction manual before brew day to familiarize yourself with how to set up your model. You don’t want to be worrying about a new piece of equipment while dealing with a brew schedule.

Important: The manual will go into more detail, but generally you need to place the burner on a flat, stable surface in an open area. You want at least a ten-foot safety zone between your burner setup (this includes the propane tank) and any structures, trees, bushes, or anything else that may be flammable.

Important: Always place your propane tank upwind of your burner to prevent accidental ignition.

How to Test for Gas Leaks

Once you have the hose attached, check that your valves are secure by performing a gas leak test. This will ensure no gas leaks out while you’re brewing.

  1. Close the regulator control valve to shut off the flow of gas between the tank and the burner.
  2. Open the propane tank valve to allow gas into the regulator line.
  3. Using a small brush or spray bottle, coat the valve connections by the tank and the burner with a mixture of dish soap and water.
  4. Examine your soapy connections. If you see any bubbles, you have a gas leak, and you need to tighten your fittings.
  5. Repeat the test until you don’t see any leaks.
  6. Turn off the tank valve once you’re certain you have no leaks.
  7. Wait at least five minutes before lighting your burner

To light your propane burner, make sure all your valves are closed before starting. Open the tank valve fully, and just barely open your air control shutter. Strike your match and be prepared to light the burner from the bottom. Otherwise you might singe your fingers. To keep your fingers even safer, use a long-handled lighter.

Once your match is ready, slowly open the burner’s regulator valve until it ignites. Once it’s lit, adjust the air shutter and the regulator valve to strengthen and heighten the flame. Remember, you want blue flames like you would see on a gas stovetop.

When in doubt, always refer to your owner’s manual. A manufacturer-recommended setup is a safe setup.

Burner Safety Tips

You need to be extra careful when gas and fire are involved. Keep your kettle, your brew day, and yourself safe by:

All About That BTU

You’ll notice propane burners often come with a measurement that says something like “60,000 BTU.” Aside from a ton of zeroes, it doesn’t tell you anything if you don’t understand what the heck a BTU is in the first place.

A BTU is a British Thermal Unit, which is the amount of energy needed to raise the temperature of one pound of water by 1°F. Burning wood, for example, gives off roughly 8,000 to 10,000 BTUs in an hour.

To get a proper boil with a propane burner, you need to make sure the burner can handle your brew kettle capacity without causing a boilover. If you’re doing a two-gallon boil with a 200,000-BTU burner, you run the risk of overheating your wort if you aren’t watching your kettle carefully.

The higher the BTU rating, the faster your kettle will heat. Just keep in mind that propane burners don’t perfectly transfer heat with 100% efficiency. The actual time it takes for your water to boil depends on your starting temperature and the weather.

You can try to calculate how many BTUs you need with a little math (and a ton of estimation). Or you can skip to the pre-calculated estimates.

Remember that a BTU is how much energy is required to raise the temperature of one pound of water by one degree. Just one tiny problem: we don’t usually measure water (or liquids in general) in pounds. That’s because the weight of liquid changes based on its density.

Luckily, we don’t have to do any crazy math to convert gallons of water to pounds. Someone already did it for us. One gallon of water is roughly 8.35 pounds. Just multiply the two to covert.

EXAMPLE SOLUTION: 5 gal × 8.35 lbs = 41.75 lbs

Note: Technically this is called dimensional analysis, and the proper equation above should be 5 gallons × (8.35 lbs ÷ 1 gallon) to cancel out the gallons unit. Really, this is only important if you like to add extra numbers or have more units to worry about.

Once you convert your gallons to pounds, we can start calculating the BTUs. The next step is to calculate how many BTUs it will take for your water to boil. Boiling starts at 212ºF (unless you’re at altitude), so just subtract an average starting temperature from your boiling point. Or you can use a specific one. Whatever you want to do.

EXAMPLE SOLUTION: 212ºF − 75ºF = 137ºF

We then put the last two equations together to figure out how many BTUs you need to get your water boiling. This is done by multiplying the pounds of water by the change in temperature.

EXAMPLE SOLUTION: 41.75 lbs × 137ºF = 5,719.75 BTUs

When propane burners list the BTUs they produce, they’re actually talking about how many BTUs the burner can produce in an hour. But the point of the burner is for boiling a big pot of water to not take an hour, so we want to look at the BTUs per minute. Simply divide the potential BTUs by 60.

EXAMPLE SOLUTION: 50,000 BTUs ÷ 60 min = 833.33 BTUs/min

You could at this point divide the number of BTUs you need to boil water by the number of BTUs produced per minute by the burner to see how long boiling would take. But we’re not going to, because there’s a minor snag we have to address first.

Remember that propane burners aren’t 100% efficient? Thanks to conditions like ambient temperature and wind, you probably won’t be looking at 50,000 BTUs even on a good day.

To account for this, let’s just assume your burner will operate at either 40% efficiency (on a good day) or 20% efficiency (on a not-so-good day). You can make this calculation by multiplying your BTUs/minute by an efficiency percentage.

EXAMPLE SOLUTION: 833.33 BTUs/min × 0.40 = 333.33 BTUs/min

Calculating BTU at 40% of Ideal

Assuming you start at 75ºF and your 50,000-BTU burner is operating at 40% efficiency, it should take around 17 minutes for 5 gallons of water to boil. That’s a little more reasonable.

Doing this check can also give you a good idea of how long you might be watching a pot of water boil on a bad day.

EXAMPLE SOLUTION: 833.33 BTUs/min × 0.20 = 166.67 BTUs/min

Now all you have to do is divide the BTUs required to make your water boil by the number of BTUs produced per minute by your hypothetical burner.

EXAMPLE SOLUTION: 5,719.75 BTUs ÷ 333.33 BTUs/min = 17 min

It’s not hard math, there’s just a lot of it.

About How Many BTUs Do You Need?

Remember, these are estimates.

Now it’s just a matter of choosing one that can provide the right amount of power for your brewing.

Propane Burners That Get the Job Done

Now that you know how much power you need, you can choose the right one for the job. Most of the ones you’ll find on the market are single burners, but some companies do make dual-burner models if you like to have more than one batch going at a time.

1. BrewBuilt AfterBurner

If you’re not taking chances with your klutzy, beer-mooching neighbor, the sturdy BrewBuilt AfterBurner is worth considering. It has a massive burner, and can produce between 70,000 and 100,000 BTUs depending on the setting.

The AfterBurner sits about two feet off the ground, so you can easily transfer your wort from the burner to a fermenter. It also comes with a windshield around the burner to protect your flame on windy days.
