The QuietFlo Water Care System utilizes a hot tub circulation pump to maximize efficiency in spa heating and filtration. The hot tub circ pump moves water at 25 gallons per minute through the EcoPur® Charge filtration system, filtering the water when the spa is not in use. By keeping the water moving at preset intervals, the circulation pump ensures hot tub water remains filtered and heated evenly. In addition to improving water filtration, maintaining a slightly elevated water temperature allows the spa to heat up more quickly, ensuring it's ready when you are. Without the circulation pump, the water would be still, which results in increased demands for spa chemicals and additional time to heat the water to the desired temperature prior to use.
