Power consumption isn't usually a big concern, people figure electricity is cheap at 5.5 cents a kilowatt hour but it can add up quickly. That being said I don't know what kind of power some of these pumps use but for sake of argument lets say one uses or is rated at 100 watts. That means the pump has to run for 10 hours to use 1 Kilowatt hour or 5.5 cents worth of electricity which means if you run the pump 10 hours a day 7 days a week you are looking at 100 watts x 10 (hours) x 31 (days) x 5.5 (cents/hour) = $17 a month give or take a bit. That all being said, if the pump is rated at 1000watts um for sure I'd stay with powerheads. I just did a quick search and found a dart that's rated for 3600gph uses 160 watts a Tunze 6100 is rated at 45 watts so the difference would be with the Dart $27.28 per month vs $7.67 per month for a tunze 6100. I didn't check price difference between the power head and the pump but you'd be looking at $20 a month in electrical usage difference between the two.
