• Drainage time: 30 minutes to 3 hours, depending on conditions. • Refilling time: Depends on the water flow rate. Household tap water typically flows at 10-20 liters per minute. If a bathtub has a capacity of 3,000 liters, filling it may take 2-5 hours.

The water level in a luxury swim spa hot tub is not necessarily better the higher it is, nor should it be too low. Generally, when using a luxury swim spa hot tub in a home or private setting, the water level should be controlled at 70%-90% of the total tub depth.

The space required to install a swim spa hot tub depends on its type, size, and usage environment: • Compact: At least approximately 5.5m × 3m; • Standard: Approximately 6.5m × 3.5m; • Large or dual-zone: At least 8m × 4m; • Equipment and maintenance space: It is recommended to add an extra 1m safety margin to the main dimensions.

The design temperature of a swim spa hot tub typically doesn't exceed 40°C, while boiling water reaches 100°C. This high temperature can severely impact the heating system and other tub components. Adding boiling water not only harms the equipment but also affects water quality. The water in a swim spa hot tub needs a certain chemical balance to remain clean and safe.

1. Use appropriate chemical disinfectants 1) Chlorine disinfection Recommended chlorine concentration: 1–3 ppm (parts per million). 2) Bromine disinfection Recommended bromine concentration: 3–5 ppm. 3) Hydrogen peroxide disinfection Recommended concentration: 10–20 ppm. 2. Ultraviolet disinfection

If multiple jets are turned on, the increased water flow will also increase the pump load, which may actually reduce the heater's heating efficiency. This is because the heater requires a certain water flow rate to effectively transfer heat, and excessive water flow may dilute the heat transfer effect.
