Your hot tub can actually be the best place to cool-off during a heat wave.With the cover off and air jets running, the water temperature will drop quickly. Put your spa in cool-water mode, or just reduce the temperature setting to 85°F or less. You can also turn the heater off.
To maintain a reduced water temperature, keep your hot tub covered during sunny days. Then run the hot tub with the cover off. This will cool the water! Because water heats slower than the outside air.
And A Cool Hot Tub Saves Energy
Without the costs of the heater, your hot tub will only cost pennies a day.
So when the temperature rises, use your valuable investment and enjoy your spa as a cool-down soak.
