When people talk about home energy efficiency, the conversation seldom leads to pool pumps and that needs to change. One of the most significant energy-consuming devices in homes with swimming pools is the pool pump. Pumps keep pools clean and safe by circulating water through filters. They often also circulate water through heaters, cleaners, water features or fountains. Depending on the pool, some use one pump to perform all these jobs, while others use multiple pumps. Traditional pumps typically have one- or two-horsepower motors that run at least five to six hours per day, sometimes around the clock, consuming energy.
