BIAB Anyone using anything like this?

I took a piece of 20 oz. copper and drilled 1/8 in. holes randomly in it. I have two brews going and I've used this on both. Before the Kansas heat took over. I have yet to get my water and heat figured out. I'm sure the burner is too big. I took it from a used forced air furnace. I use a thermostat to turn it on and off at my desired temps. I was thinking when I use it again I can use a filter and a pump. The wort is coming out very cloudy. Can anyone give me any advice regarding this?

Is the copper cylinder your bag/basket?

Yes. There is a bottom with the same holes in it.
