Typical filtration cycles are four hours, twice per day (for hot tubs operating a single or two speed pump). Reducing the cycles to 3 hours twice per day will save water pumping energy. These circulation times should be set for off-peak hours. (Some hot tubs have small, low wattage circulating pumps that run 24 hours a day. Typically these draw less energy than a 100 watt light bulb.
When we bought our house it came with a hot tub. We've been told by numerous people who own hot tubs it costs on average about $30/month to run. At first we wern't to keen on the idea of paying the extra power to run it, but decided to try it out. Turns out we really like it, but it seems to cost more to run than we expected. We've replaced the cover, turn it down when not in use, and put it on econo mode. The hot tub is only 3 years old. Just got our power bill and its showing for months of Dec/Jan we used 68 kw per day!!
