Default freezing propane tank

Now that I am using a Banjo KAB6 burner, I've been having problems with my propane tank freezing 1/2 through the boil. I've read that getting a large tank will help, but after just buying a 2nd 20lb tank, I'm reluctant to spend $80 on another one. I've thought of getting a bucket large enough to hold the tank and put hot water in it. Anyone have better ideas?

I went with the larger tank. You could try hot water around the valve. If you have enough of it you might keep it open.

I bought a second tank for that exact same reason. Now I always brew with two tanks and switch out when one freezes up.

First time I froze it up I thought it was empty and brought it for a refill. The propane guy laughed and told me it was still half full.

I also find tipping/rocking it helps but not sure if this is dangerous.

I put my tank in a tub of hot water, only about the lower third or so up the tank.

the winning answer and the water does not even have to be hot for it to keep the tank from freezing.

I just place the tank close enough to the flame to warm it up enough to prevent freezing. Of course I don't get it close enough to explode.

yes the water is the way to go. the reason it is freezing is because of the volume of gas flowing through the valve. I am a welder and every time I put on a new argon tank and do alot of heavy welding I get the same thing, I use a wet rag to help.

sounds tricky figuring out where the "won't explode" distance is.

Having been a fireman, I've see 100 lb cylinders setting next to a burning building. The small cylinders have a pressure safety release so they don't explode but they really push out a long blue flame when the pressure relief goes off. You don't want to be in line with it as the flame will reach out 30 feet.

If you have an old electric blanket or a back heating pad, those would work too.
