Q: Your kettles are listed as 1.2mm thick. I've seen 6mm thick, is that a typo?
A: Our 10, 15 and 20gal kettles are made from a 1.2mm (18 gauge) 304 stainless steel (18/8) and our 30 and 50gal kettles are made from 1.5mm thick 304 stainless. Based on what's out there we have the thickest kettles on the market. Many entry level kettles are .8mm (22 gauge). For reference a stainless steel beer keg is about 1.5mm (16 gauge) and is meant to be shipped around the country and beat up by drunk college kids.
As for the 6mm thickness... When you see 2, 4 or 6mm thicknesses for a kettle it is made from aluminum. Aluminum is much lighter and less tough than stainless steel. A 6mm thick aluminum kettle will dent much easier than a stainless kettle only .8mm thick. When it comes to kettles you really get what you pay for.
Q: What is the difference between your 'vertical' and 'horizontal' coupler configuration?
A: The vertical config is kind of the standard for homebrewing and that's why we offer it. The horizontal is our solution to a problem. The vertical coupler config has the top thermometer coupler 6" from the bottom. Now if you're to buy a 15gal kettle that means you would need approx 5 gallons of liquid in the kettle until it reached the thermometer. If you wanted to do a 5 gallon batch in a 15 gallon kettle the thermometer may not be submerged. The horizontal configuration keeps the thermometer submerged at all times.
Q: How big of a kettle do I need?
A: The standard sizing is typically:
5 gallon final batch = 10 gallon kettle
10 gallon final batch = 15 gallon kettle
Q: Can your kettles be used on an outdoor turkey fryer burner?
A: Yes! The kettles were designed to be used outdoors on a turkey fryer burner. We personally use a Bayou Classic SQ14 for testing which puts out 55,000 BTUs but customers have told me they've successfully used a burner close to 250,000 BTUs.
Q: Can your kettles be used inside on a stove top?
A: Yes! A stove top doesn't put out the heat of a turkey fryer burner but it'll still work. Caution to those with a glass top stove... I've read on forums that someone had their glass top crack because they used too large of a kettle. We would advise using a smaller kettle if stove top boiling is your only option.
Q: Should I use Teflon tape on the threads?
A: Yes! Teflon tape is safe to use and will hold up to the heat. The threads are tapered and thus need Teflon tape otherwise they will leak.
