Save Energy and Dollars With a Dual or Variable Speed Pool Pump-FPL

By: Brad Goar


Q: I have a 10 year-old, single speed pool pump and hear that new pumps are more energy efficient. How much energy can I expect to save with a newer, more efficient pump?

A: Did you know that a pool pump is the second largest user of energy in your home behind the air conditioner? Just like replacing older appliances with more energy efficient ones, the same applies to your pool pump.

In fact, the State of Florida passed a law in 2011 that requires new residential pool pumps to be more energy efficient. The law changed the types of pool pumps and motors that can be installed on new residential pools. Older, single speed pool pumps – that run at one speed the entire time they are on – are the least energy efficient of all pool pumps, because they have to run at higher speeds to filter your pool. Newer, dual speed pumps or variable speed pumps are more energy efficient than a single speed pump, which leads to saving energy and ultimately money.

For example
According to an FPL commissioned study performed by the University of Miami, a dual speed pool pump on average can save up to 24 percent over a single speed pump, while a variable speed pool pump can offer up to 72 percent energy savings. In terms of dollars, a customer with a 10,000 gallon pool with a single speed pump running six hours per day could save approximately $105 per year on their energy bill if they upgrade to a dual speed pump. However, they could save up to $316 per year if they opt for a variable speed pool pump.

What to consider
Installing a new variable speed pool pump can generate bigger savings, but will cost more for the initial investment. However, new pumps can pay for themselves in as little as eight months. You should consult a professional to handle the installation, as the pump’s settings will be programmed based on a number of factors, including the size and location of the pool. As for when you run the new pump, there are no additional savings achieved by running the pump at night versus during the day. Lastly, if you currently have a single speed pool pump and it’s running well, continue using it until it no longer works.

Another way to save
You can reduce your pool pump’s run time by two hours or more a day to save up to $100 annually. We recommend running your pool pump six hours or less per day in the summer and four hours or less per day in the winter.
