Even in sub-zero winter conditions, the internal water temperature of the Whirlpool spa hot tub remains between 37°C and 40°C. The jets of massage water not only provide comfort but also ensure continuous water circulation, preventing localized temperature drops.

Larger water volume, longer heating time. The water volume in a swim spa tub is often 4 to 6 times that of a hot tub. Heating such a large volume of water from room temperature to 38°C naturally requires significantly more energy.

Sure! When the body is immersed in hot water at 38-40℃, the blood vessels in the skin naturally dilate due to the heat. The blood vessels enlarge, increasing blood flow and delivering more heat to the limbs, gradually relieving the feeling of coldness.

Clogged masssage jets not only affect the user experience but can also cause the following problems: 1. Reduced water flow and decreased massage effect 2. Increased load on the heating system 3. Increased risk of bacterial growth 4. Increased noise

In public swimming pools or spas, hygiene standards generally require users to rinse thoroughly before and after entering the pool/spa to reduce the risk of contamination and cross-infection.

Thermal therapy studies have shown that immersion in water around 40°C for 15 to 30 minutes can increase skin blood flow by 30% to 50%. Combining a spa hot tub with jet massage can enhance local muscle blood flow and accelerate the excretion of metabolic waste.
