Hey guys, I just got my keggerator up (converted chest freezer - Posted it in the show me your kegerator) and running but there is roughly 12 feet of beer line that won't be kept cool. I have a fan blowing the air up an 4 inch insulated tube with 4 beer lines running through it. Sadly I checked the temperature half way up and it isn't keeping cool enough. There are 2 bends in the tubing which I believe is preventing it from cooling the line up further.
I read some older threads about getting a pond pump and placing a filled water bucket in the freezerand having a continuous flow of cold water up to the beer lines. - I do have a concern about this though wouldn't the pond pumps motor heat the water up and prevent adequate cooling? I don't have a ton of space in my freezer I could probably get 2, maybe 3 gallons bucket to fit which I would have to think would get warm.
Less idealy I figure I could just plan ahead 20 minutes and turn on the pump before I start drinking to cool the line and unplug it when I'm done.
Any help would be wonderful!
