In the United States, according to the provisions of NEC Section 680 for swimming pools, spa hot tubs and similar facilities: · The circuit breaker box or any electrical equipment that requires manual operation must be installed at least 5 feet (about 1.52 meters) away from the spa hot tub.

For those who have a large outdoor space and want to use a spa tub for parties or large family events, a large outdoor spa hot tub is the best choice. Large tubs can usually accommodate 7 to 10 people, or even more.

When you find signs of overheating in the pump, heater or control panel, you should first turn off the outdoor whirlpool hot tub immediately and cut off the power supply to avoid further operation that may aggravate the problem. By stopping the operation of the equipment in time, you can prevent the motor from burning out or further damage to electronic components.

According to some studies, the calorie burn of soaking in an outdoor spa hot tub for one hour is about the same as walking for one hour, which is about 100-200 calories. While this number sounds good, it is limited compared to the calories burned through aerobic exercise (such as running, swimming, etc.).

Back pain often affects the quality of sleep, and a whirlpool spa hot tub can help relax the body before bed, relieve pain, and thus improve sleep. Studies have shown that warm water baths can help the body cool down naturally and induce deeper sleep, which may be an ideal non-drug intervention for those who have trouble falling asleep due to pain.

If the winter temperature in your area is relatively mild, usually above zero, then there is no need to seal the spa hot tub, just do routine maintenance. However, if the temperature is below freezing for a long time, especially in areas with frequent extreme low temperatures, it is recommended to seal the spa hot tub to prevent the water pipe from freezing and bursting.
