how often should a hot tub run
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.
