I have been researching buying a chiller but settled on other means of cooling. Thing is when I was working on where I would place the chiller I saw quite a few people with pics of chillers in the sump cabinet. After a bit of thought I realised that that is kind of " A snake eating its own tail" the chillers exhaust will heat up the cabinet and the water in the sump and therefore the tank itself. Then the chiller will have to work harder to cool the water to compensate. Must be extremely inefficientand a waste of power. Then I realised to get maximum efficiency you would need to exhaust to outside.......am I wrong?
