Conserve Energy & Save Money

Covering the Cover

Always close and secure a snug-fitting, foam-insulating cover. Replace the cover if the interior foam becomes water logged or broken. Consider adding a floating thermal blanket to retain heat and to prevent moisture from building up inside the cover. Ask about the cover's R-value, a measure of insulation power. Standard covers typically have an R-12 insulating value, but some manufacturers add higher-density material to beef up the insulating ability.

Control Temperature

Set the temperature of the spa water at 102 degrees F or lower to save on heating costs. If the hot tub has a timer, shift heating to off-peak hours (6am - 10am and 5pm - 9pm).

Going Away

When away for a week or longer, turn the thermostat down. It will cost a few dollars to reheat the water, but the longer you are away, the more you can save.

Water Watch

To avoid wasting water, repair any leaks and drain the hot tub only as needed; draining often depends on the frequency of use, but it is typically every three to six months.

Wind Factor

Shelter the hot tub with privacy panels, fencing or shrubs to block the wind. This could lessen energy consumption by as much as 5 percent.

Out of the Shade

Installing the hot tub in a sunny spot can decrease energy use by an additional 5 percent.

Good Maintenance

Keep the hot tub in good working condition, following the manufacturer's maintenance recommendations.
