Description 

DC pool pumps, 1/7 HP or 100 Watts, are installed in tandem to the existing AC pool pump (typically 2-3 HP). During the filtration cycle or while moving water through the pool filters, DC pump will be turned on to save energy. Since the pumps remains in this mode most of the time, average usage will remain close to 100 watts. The AC pump will be turned ON only if the water features such as spa or waterfall etc. needs to be operated. Thus, by using a 100 watt pump most of time instead of a ~1.5 kW pump, the savings potential is huge for this technology. In addition, the noise levels are reduced because the pump is a DC brush less motor.
