My chiller was in my wet room 12x12 where all my pumps ect are. Room runs very warm expecially when the chiller is on because the evaporator coil is being cooled my a fan which blows the heat in the same room. I do have multiple fans in the room and one over the sump but no way with out the a/c blasting would the tank go below 83-85 on a day like today. Now my tank is holding at 78 so It gives me time to work on my $900 POS chiller.
