Hey Guys -

Just bought a house that has a small outdoor kitchen with a gas line connection. Can I boil seafood with natural gas? If so, how, if at all, is it different then using propane? Advice is appreciated. Thanks. Geaux Tigers. Who Dat!!

Honest answer, you won’t have enough pressure with natural gas to get the water boiling quick, and once you do get it rolling, drop 30/40lbs of cold crawfish in it and it’ll take forever to get rolling

Yep. My FIL ran a line outside to boil crawfish and gave up after a couple attempts took forever.

I use one like this I bought on eBay for about $40. I modified an old unused burner and attached it with metal screw clamps. It takes a few minutes longer to boil but I'm never out or low on propane! This thing puts out a LOT of heat!

I grew up with propane boiling because of the rapid return to boil that propane pressure provides versus natural gas. However, I also grew up with a natural gas line outside my home. I am not opposed to boiling using the above jet burner if more people have experimented with it for natural gas. They do make them in all different type of sizes. Interested in other people’s opinion.

The issue is gas pressure. The natural gas pressure in our homes is reduced significantly by gas regulators (the grey round things next to the gas meter). Therefore, most gas lines connected to the house put out too little BTUs to heat the water fast enough.

If you were building a new house, you could install a high pressure meter and run a line to the boiling location. The plumber would then install a regulator near the house to step it down to the proper pressure for your home's gas equipment (heaters, stove, etc.) Not sure if that would meet code though.

That said, I find it easy enough just to keep a propane tank around for the occasional crawfish boil.

I use a G4 natural gas burner. Goodwood hardware in Baton Rouge sells them. BBQ Guys
I ordered straight from the guy that makes them. You may be able to find his website with a video of the burner in operation. They run around $400 dollars including a heavy duty 10 foot hose. I bought a 25 ft hose for an extra $100.

Then I bought a Cajun rocket pot Rocket Pots, which is a pot with a bunch of nipples on the bottom that supply more surface area for the flame to contact, thus better heat exchange. The company flopped a few years ago but I saw on facebook theyre back in production with a better welding technique. Also saw a company called Tunnel Tube Tunnel Tube making a pot with square tubing welded on the bottom which works off the same principal with heat exchange. Both of these pots run around $400.

So it cost around $800 to get set up and takes about 150% of the time to come to a boil as a propane jet burner and normal pot. But well worth it with how quiet it is and not having to chase down propane bottle fill ups and have propane bottles freezing up when running low.

That was a lot of info but hope it helps.

Back in the early 70's, we used our house gas line to boil crawfish. We had a tap off an outdoor gas heater. My dad scavenged a burner from a home gas water heater, so it was designed to use NG. It looked like a huge banjo burner. It worked, but I can't comment on how long it took to boil water, I just don't remember.

Back then, boiled crawfish wasn't readily available in stores. You mostly had to catch your own, which we did at the spillway. Home boiling crawfish was just coming into the New Orleans area public consciousness. You couldn't just walk into a store and buy a propane burner setup. You pretty much had to cobble one together yourself from parts you found from various sources.

It can be done, but propane is better.

I use the same burner as fatboydave, I’ve used it for 2 seasons now. Used it at least 10 times. Works great. I got the burner from Amazon and had a buddy of mine build a frame to put it in. It takes about 16 minutes to get the water to a rolling boil from scratch. It gets the water boiling again quickly after adding crawfish and stuff, not much difference between the gas and propane once the pot is hot. It’s way more convenient than propane for me and its very quiet when using it compared to a regular propane burner.

The answer is volume. You need to have a large amount of volume gas flow to boil with the multiple jet burners and natural gas. I have a 32 jet burner, I use a 3/4" gas hose and fittings. The hose comes off a 1 inch gas line close to the meter. I can have water boiling in a little over 12 minutes or so.

I love not having to stock propane tanks around the house and it's cheaper. Very quiet too. I can let my crab traps stay out later, come in and boil at 9pm and not keep my neighbors up if I want to

I also have converted my BBQ pits and smoker to run on natural gas too. Very convenient

It takes longer, but it works.

Start with hot water if you can. Other than that it added like 15-20 minutes to the cook if I remember right.

We had no issues with texture or anything.

Yes, plenty do it.
Some burners may require a slight moderate at the nozzle.

Friend of mine had a 3/4" line installed at his house for a tankless water heater, and he had the guy also run a 3/4" line to the edge of a concrete pad he has in his backyard. Plan is to boil off of that line, but he hasn't had a chance to try it out yet.
