Had the crazy idea today of mounting a coldplate exchanger in the back of my fridge and running a couple of tap lines from outside in and putting a perlick or two on the side of the fridge. Has anybody tried this and what were your results? Seems like it would save on running another fridge as a keggorator... Let me know. Thanks.
Even if the plate needs to be in water to maintain temp, it shouldn't take up more than a corny keg worth of space. I can see this working to run warm ale kegged beer through a lager temp fridge, and getting proper temp ale.
I've been using a similar setup for over a year, works great. I have a 7 pass chiller with 3 taps. I do run the first two lines through the chiller twice, to be honest I can't tell the difference in temp to the third line that only passes once.
