You seem to forget we all don't have environments suited for growing or keeping liquids cool. The heat the Chiller pumps out will have no impact on the rooms temps. Its been running for a week works perfectly with no added temp to the room. My rez was a PITA to keep cool last year. My veg room has a metal roof witch radiates heat like an oven. Watering the plants with hot nutrients will kill the plants or harm them. I wont fight with it anymore. My options are limited. Keeping the Rez insulated in my environment will help keep it cool with the chillers help. It will be more efficient with the drum wrapped so the chiller wont have to cycle so often. I work with what I have.
