I had to purchase a new (used) chiller that was twice the size of my old Aquanetcs chiller so the new one is 1/2 Hp. I needed to get the heat out of the the basement with the bigger size so I built a condo for the chiller on the external wall with the lines running through the wall. I am very pleased with how it turned out and could not believe how much heat that the chiller puts off - it would have been a never ending battle to get rid of the heat had I installed it in the basement room.
