Came over from my thread, thanks for the link! I may have to try if all else fails.

Default Not pretty, but works.

If it's hot outside and you wear a sweater, you are going to be really hot. Same with a pot of hot water. A towel and clip ($0.50 at Loew's) was all I need to get my turkey fryer pot boiling 5 gals with no problem. My pot also holds temperature during the entire 60 mins of mashing (which used to be a big problem). Adding foil around the towel would probably everything even more efficient, but the foil is more fragile. This setup is easy to clean too.

Yes, I use a gas burner.

Default There is fire proof and fire resistant

I know this quote is old but I did get some engine compartment insulation from Pep Boys and this is what happened when I had the fire all the way up.

Notice that the aluminum did not burn and in fact the fiber insulation only melted. It did flame while the fire was hot, but went out when I turned the flame down.
It burns me up though because the roll cost over $35.
I think I will go to Home Depot and get a roll of water heater insulation which is alluminum foil over fiberglass and see if that can stand up to the heat. It isn't that I can't get it up to a boil, it is that I am impatient and want to get it up to a boil quicker. Brewers are supposed to be patient though, arn't we?

I used the automotive firewall insulation J.C. Whitney sells (and I used the foil tape to cover it, and the spray glue they sell for the purpose to stick it to the pot) and it's held up. It's not only withstood the stovetop burner, but another 3 1/2 years of duty on a Bayou Classic SP-10 after I went all-grain. It's easy to see from the pix below that there's been no burning of any kind. (The black spots on the outside are just some splashes of wort that have dried on the outside of the foil tape.)

In fairness to the Pep Boy’s product, I was stressing it quite a bit more than you are. First off, I had the foil side toward the pot and did not cover the fiber side with tape. Second, I had the insulation about an inch off of the pot so that the hot gasses from the fire would go up on the outside of the pot and help with the heating instead of just going off into the wide blue yonder. Third, and this may be the one that did it in, I extended the insulation down below the pot to be even with the fire so that even less of the heat would escape. The damage to the insulation started below the pot, but extended up a few inches above the bottom of the pot.

I still think it is a good idea to catch the heat and guide it up the side of the pot, but insulation is not the solution.

Yes- I can see the difference now in how we applied it. I just wanted to get my anæmic cooktop to get a full 6.5 gal. boil going faster. The insulation as shown in my pix cut it from >60 min to <40, so I was happy.

Has anyone has any smells coming off of this stuff? I'm just worried about it melting a bit and imparting weird smells or tastes (perhaps even putting something dangerous into the brew).

Thoughts?

I didn't notice any smell from my setup after a few batches. I think the key is to keep it well away from the bottom of the pot.

Okay, I am a bit afraid of a heat stick, don't want to spend a tonne of money on equipment, and would like to keep things simple. But, I would love to cut down my boil time.

So.... I think I have to try this. I am going to go the tinfoil root. But I am thinking I might use like $10 worth. Crumpling it up along the way so I get lots of air pockets. That should give me a good thermal retention or R-Value while still being completely bombproof heat-wise and keep costs low. I will let you all know how it works out come brew day.
