You also have to look at the temp. of the ice. Ice is colder than 32F, so you use calories to heat the ice TO 32F, then more calories to MELT it, then even more calories to HEAT it to say 50F.
Well 44lbs is only about 5 gallons. If its winter and you have a big freezer outdoors thats not hard.
check out this site if want to do some calculations (maybe it will help with your new build):http://www.3dplumbing.net/ontplumbing/latent_heat.htm
ice 0 to 32 = 16BTU/lb
ice 32 to water = 144BTU/lb
the state change gives most of the cooling capacity.
By the way, I was impressed with your old rig. Yooper even showed me the magazine article (BYO?). I gotta get over and check out a brew day with it.
