It might be time for a new pool pump. Most people wait until their pool pump dies before they look for a replacement, but it might be the one thing that saves you money if you do it sooner than later. This might go against everything you have been raised on, but..Replacing your single speed pump with a variable speed pump gives your pool a quieter, more efficient circulation system that ultimately will save you money.
How can a pump that costs more, save money?
The difference in pumps is exactly how it sounds: a single-speed pump operates at one speed no matter what type of work it is performing, while a variable-speed pump can be adjusted to achieve the ideal filtration flow rate with the least amount of energy consumption. Basically, variable speed pumps work efficiently and effectively, while single-speed pumps run constantly at maximum flow rate, consuming HIGH energy often around the clock, and a majority of the time providing too much circulation than the pool filtration system actually needs. Yes, there is waste, even in pool pump energy.
According to a recent study by the National Renewable Energy Laboratory, a pool pump can be the second largest energy user — and most often is the largest energy user — in the home. Switching to a variable speed pump, however, can reduce pool pump energy use by 50 to 75 percent (or even more depending on your usage factors). In addition to saving energy, variable speed pumps are noticeably quieter, require less maintenance, last longer, and, through slower water filtration rates, allow for better and more effective filtration of the pool water.
There are other benefits to changing pumps, beyond just energy savings. The slower circulation rates also put less strain on the filters, plumbing, and other parts of the system, which reduces the chance of leaks, repairs, or premature plumbing component replacement.
Overall, upgrading your pool pump to a variable speed model will protect your pool better, enhance your swimming enjoyment, and save you money in the long run. Variable speed pumps do cost more than single speed, but the energy savings achieved by the upgrade typically pay for the higher cost within the first year.
