From the Monster Flow 7HP pump to the 1.5HP Smart Flow pump, all are designed to push the maximum allowable pressure through to our specially designed Luxury Trillium Massage Jets. During your spa's filtration cycle, your jet pumps are activated to pull and push water through your hot tub filter. During the filtration cycle, our Extreme pumps will run on an ultra low voltage (1.2Amps for 5HP Super Flow Pumps) and at one third the RPM (3450 high / 1150 low).
Programmable filtration cycles allow you to control when, and for how long, your jet pumps activate to purge your hot tub of debris. During the programmed filtration time, your hot tub pumps will consume about as much power as your backyard aquarium pump.
Many hot tubs use a 24 Hour Circulation Pump or “circ” pump that runs 24/7 to constantly circulate the water in your hot tub. Circ pumps are touted as being a cost-saving feature due to their small size and low power draw. It is true that circulation pumps use less energy (0.7amps compared to 1.2amps for Coast Spas’ 5HP Super Flow) however, instead of running at an average of 8 hours per day (Coast Spas’ programmable filtration), they’re running continuously 24 hours a day, 7 days a week.
Not only does using a circulation pump increase your energy costs, it also puts high levels of strain on the pump itself which leads to premature failure.
See the the chart below showing the energy requirements and pump specifications for both Coast Spas’ 5HP Super Flow Pump and a standard Circulation Pump.
|Pump Style||Coast Spas Super Flow (5HP 2 Speed 56 Frame Pump)||Circulation Pump (48 Frame)|
|Revolutions Per Min (HI - LOW)||3450 / 1150||1725 / 1425|
|Electrical Voltage (Volts)||230||230|
|Electrical Currents (Amperage)||1.2||0.7|
|Power in Watts||276||161|
|Average Usage per Day (Hours)||8||24|
|Total Watts Hour Per Day||2208||3864|
|Total Watts Hour Per Month||71.22||124.65|
|Operating Costs Per Month||$19.14||$40.19|
Above calculations are produced in an equal environment for each system with a set temperature of 102 degrees Fahrenheit. The energy usage and cost above does not factor in the energy required to heat the spa (for both Circ and Non-Circ Systems). Factors that can affect the energy cost (for both systems) are: Volume of spa (water capacity), set temperature, frequency of use, ambient temperature and cost of KWH.
