I've been doing this for a few years with a steamer basket and it works just fine. Every 15 minutes I stir it, then I'll warm it back up. Sometimes I have to lite it a couple times between stirs. I've thought about maintaining a very small flame but haven't actually done it.
It's pretty easy and...
I've been recirculating for a pretty good while now. This is what I would try if I were you. Make a 5 gal. batch, full volume recirculating to the top of the bed with a normal crush not a fine crush. See if your luck is better. I believe your crush might be to fine and your making to high of a...
Not to stir a debate on the ops thread but, the concept of a basket resulting in mashing in a smaller volume of water doesn't make sense to me. I've read that thought here multiple times and can't wrap my head around it. After mashing in, the grains take on water and end up at the bottom of what...
I've done about 30 batches using a basket in the kettle and I can't complain. That is how I started from day one. I used to insulate the pot and let it sit, stir it a couple times etc. I've been recirculating during the mash for a couple years without insulation and just adding heat when needed...
Nice looking rig you have there. I've been recirculating thru the bed for about 3yrs. using propane to maintain temp and a small spray head under the lid. It's worked great for me only having one issue with low flow through the bed causing the pot to over flow. I've stopped asking for double...
Wish I hadn't have read all this stuff. I've been thinking I had my recirculating system all worked out since I rarely have any issues. I've read about hot side oxidation before but never in this amount of detail (by following most of the links and reading the PDF). I guess the tweaking will...
You might need to go with stainless tubing fittings. If it were me, I'd look around the storehouse at the chemical plant, maybe snoop around where the analyzer guys hang out. this link will give you some ideas.

I've got a batch with this yeast in a bucket right now, 5 gal. in a 6.5 gal. bucket. I thought it was going to blow the lid off a couple days ago. Had to swap out the airlock for a blowoff and clean up a small mess. I've tried to hold it at about 64 degrees for the clove flavor over the banana...
Wish I could give you a simple answer but I think your entering the twilight zone.
This water stuff is complicated to me, good luck with your adventure.
He is a water expert letting you know your water profile will not effect your efficiency.
You can use a fine crush with BIAB and the correct amount of water and you should get good efficiency. Might try mashing longer if your not.
