New Variable Speed Pools Pumps Slash Utility Costs

Pool owners can save hundreds per year

Few pool owners realize that their pool pump can use more electricity to run than any appliance in their home—often costing more than $100 per month where utility costs are high. That’s because most pool pumps are inefficient single-speed models using larger than ¾ HP (horsepower) motors. For decades this was the norm, because electricity costs were low and the supply was abundant. However with electricity rates increasing, pool owners are feeling the pinch.

Just how much power do pool pumps use? Consider the results from a 2004 study by Davis Energy Group for Pacific Gas & Electric. They found that to operate California’s 1.2 million pools requires roughly the same output as one nuclear power or two conventional energy plants.

The solution? Pumps that work smarter, not harder.

Fortunately, far better options are available today. The most dramatic energy savings come from digitally controlled, variable speed designs using permanent magnet motors motors. Permanent magnet motors assure a 30% base savings compared to induction motors. Then, savings build up to 90% with the ability to custom program the optimum pump speed or water flow for different functions—filtering, heating, cleaning, spa jets, and water features.

The secret to minimizing pump energy use is to operate at the lowest speed needed to accomplish a job. It takes far less energy to move water slowly than quickly. In fact, reducing pump speed by half reduces power needed to an eighth of what was needed previously to get the job done. A good analogy is your car…you get far better gas mileage at 30 mph than at 90 mph. These new pumps allow you to set and adjust pump speed to achieve the minimum energy use.

According to Pentair Water Pool and Spa, their IntelliFlo® and IntelliPro™ variable speed pumps routinely reduce energy use by 30% to 90%, or more, depending on the models and circumstances. Savings in excess of $1,000 per year have been documented in many instances. Some typical annual savings for the IntelliFlo® are shown below.

The savings with new variable pumps are so extraordinary, many pool owners are switching, even though they recently purchased their last pump. Cost for the new variable speed pump is quickly paid back in energy savings. And, variable speed pumps run more quietly and help provide cleaner, more sanitary pool water.
