How 2-Speed Savings Are Achieved

 

 

 

 
A 2-Speed motor runs at about 3450 rpm (revolutions per minute) at high speed (the same as a 1-speed motor) and 1725 rpm at low speed. Thus, low speed water flow is reduced by about 50% compare to high speed.
   
A typical 1.5 H.P. pump draws about 1.9 KWH (kilowatt per hour) in high speed operation. However, in low speed in draws 0.57 kWh The energy (electricity) to run a motor at low speed drops by 70%!
   
The 2-Speed Energy Saver provides a minimum amount of high speed operation before switching to the cost saving low speed mode. Pools with D.E. filters or sand filters require high speed operation at the start of the filter cycle. Most pools with automatic cleaners require additional high speed operation. The amount of high speed operation can be selected to match the requirements of the pool and equipment.

 

Using a cost of $.11 per kilowatt/hour and standard filtration times for an average sized pool of 17,000 gallons with a 1.5 H.P. motor gives us a usage and cost of:
One Speed Motor 2-Speed Motor and Controller
617 kWh/Month 300 kWh/Month
$68 per month $33 per month
$815 per year $396 per year

Yearly Savings = $419 per year or a savings of 50%!
