How much water does a standard misting system use? What is the environmental impact?
One mist nozzle uses about 1 gallon of water per hour. A 15 nozzle system will use approximately 15 gallons of water an hour. So running the system for the peak 3-4 hours of the day will use a quantity of water equivalent to a load of laundry. Studies have shown that using a patio mist system saves on air conditioning which uses considerably more electricity and produces a tremendous amount of residual heat. Also, pre-cooling your a/c compressors with mist is a great way to improve the efficiency of your hvac system.
