Use An Energy Efficient Pump

A Better Pump Saves Money.

Traditional pool pumps are fixed speed and thus can be considered as wasting energy. This is due to the nature of filtration, which is a basic, low energy function.

An energy efficient pumps can yield significant energy savings, (upwards of 18% and as much as $300 per year) when they are optimized and sized correctly. A controller sets the best speed for the task at hand, there by matching pump speed to needs of the pump at that point.

If your existing pool filtration pump is in need of replacement, carefully look at getting an energy efficient pump replacement, which will save you significant energy costs. Though an energy efficient pump has a higher initial cost, it will usually pay back the value inside of a year or so.
