Hi guys,
Here's my humble experience.
Past: 1/3 hp Daeil chiller inside cabinet next to sump. Struggled to maintain a constant temperature during hotter months and ran practically non-stop. In order to dissipate the heat, have to add another fan inside the sump. Livingroom is hot and noisy due to chiller.
Present: DIYed a 1/2 hp Starmex connected to a Titanium heat exchanger. Cooler and quieter livingroom, paid lesser for my uitilities, lesser cut in and out, sump fan not running since the change.
