Another thing, you don't need to heat the sparge water. Cold water will give you the same results and provide an added benefit of cooling your grain, making it easier to handle when squeezing the last of the wort out of it.
This BIAB basket is exactly what I have been looking for. I have asked Chad for a quote for one including feet similar to yours to keep it above the pickup - only problem is I am in Australia so the postage might be a killer.
I want a single vessel recirculating HERMS and this is the missing link. My HERMS uses a household kettle jug with a custom coil from Gryphon Brewing (no other pots required).
Hope it works out for you foles. I ended up cutting off the legs on my basket and changed out the kettle dip tube for a brass 90 elbow so it would sit closer to the bottom of the kettle. It was sitting a little high in the kettle for my liken.
With the added sparge and a fine crush I've been getting 90% mash efficiency. I think I have it pretty well tuned in.
I'm also going back to electric, just ordered a 3500w 220v induction plate. The propane burner worked great but I had to keep windows open to keep CO alarm from going off and that's not good when it's -20 outside.
