Was all set to send a 4" insulated pipe from keezer to a box that is partially in the wall and partially protuding. In that pipe would be a 2" hose. Between the inner hose and the outer hose would be the beer lines. Air gets pumped from keezer, through inner hose, and then returns in the outer hose with the beer lines. Box is insulated and caulked to be air tight. There are a few HBT posts describing this approach.
Just emailed with @tprokop and he seems to be saying that his gets a lot of condensation which means that he is getting a lot of outside air leakage. So much so that he is switching out for a liquid cooled system. In this system a single trunk carries your beer lines and two cooling lines with insulation around. A pump sends cold liquid (water or glycol) in one of the cooling lines and returns through the other. There are cooling blocks one can attach to the shanks to send the cooling liquid through those as well.
Any comments on this?
A) With the liquid cooled system, the beer lines are going to have to split from the cooling lines a several inches before the taps and the box they are all in will not be kept that cool even if insulated. Will that cause a problem
B) For a 4 tap system the pump is going to need to pump through two u-turns for each of the cooling blocks before returning. Pump recommended for that?
C) The trunk lines come with their own beer lines. Anyone have any experience about whether those are any good? Any materials lists for building your own? Takes aluminum foil, plastic wrap, etc.... Seems like a lot of work just to get better beer lines.
D) Will cold water from the kegerator be sufficient for the cooling lines or will a colder liquid be required? Certainly going to be a lot harder to use a second cooling source.
E) Alternatively, if going with the air cooled approach, maybe a plastic box interior for the wall box rather than just wood with insulation and caulking to keep it more air tight? I have a wall stud up the middle of mine so that's going to be tough.
Thx for the help from anyone who has tried these.
Cheers,
