I just completed a brew yesterday... I used my submersible pond pump to pump (salted) ice water from a cooler, through my chiller, and into a 5 gallon bucket. I cooled 5.5 gals of wort to 70 degrees, and filled my 5 gallon bucket 2 and a half times... for what it's worth.
Same problem. I went with at pond pump from my LHBS. I sink the pump into a cooler with a cup or two of rock salt and about 20 lbs of ice. Works very nice. This is the pump I picked up. Seems to be strong enough, and not too expensive. http://goo.gl/UG6p8
Thank you very much for posting your recipe. It sounds (and looks) delicious. I would like to try this.
I have a dumb newbie question. After reading your recipe, I'm not sure what to do with the half pound of honey malt. I assume I should steep it in the boil water for 15 or twenty...
