actually it does! I have a temp probe in the sump, and in the main tank, the temperature does not drop too much from the sump to the main tank +/- 2 degrees max. I do not see the heaters turning on that much considering the temperature in the crawl space gets down into the single digits. I also insulated the plumbing lines to keep anything from wasting energy. All of my equipment, spare parts + media fits on this costco rack.
Most important thing for energy conservation has been the insulation. Dont skimp or cut corners on it. If you do it right, the remote sump will not add any additional cost or trouble to the main tank.
