Timer
Hot tub filtration and heating systems use timers differently to maintain the cleanliness and temperature of the water.
Filtration System Timers: Hot tub filtration cycles are periods of time when hot tub pumps are scheduled to run automatically, circulating water and chemicals through the filter system and pipes. The filtration cycles will take place at preset intervals and when you use your hot tub. Most residential spa owners do not need to run their hot tub pumps all the time. Unless the spa is used multiple times per day, a filtration cycle of 2-8 hours, twice a day, should be enough to keep most hot tubs sanitary. By default, most hot tubs will start their filtration cycle at the time you first turn on the spa and then run on a schedule every 12 hours after that.
Heating System Timers: The heating system in a hot tub doesn’t typically operate on a timer in the same way as the filtration system. Instead, the heater operates based on the water temperature. If the water temperature drops below a certain point, the heater will turn on to bring it back up to the desired temperature. This ensures that the hot tub is always ready for use.
In some advanced systems, a secondary pump known as a circulation pump runs around the clock, even when the hot tub is turned off. This pump circulates water through both the filter and heater continuously, providing constant filtration and maintaining a steady water temperature2.
Remember that these are general guidelines and actual usage may vary depending on your specific hot tub model and usage patterns. Always refer to your hot tub’s user manual for specific instructions.
