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?
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 can apply to your pool pump.
Single speed pool pumps are set to run at higher speeds that use more energy. The level of savings will depend on whether you switch to a dual speed pump or a variable speed pump – both will be more energy efficient than a single speed. Dual speed or variable speed pumps can run at different, lower speeds, and the energy saved can be considerable – reducing pump speed by 50 percent allows the pump to use just one-eighth as much energy.
According to a University of Miami study, a dual speed pool pump on average can save 24 percent over a single speed pump, while a variable speed pool pump can offer up to 72 percent 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 if they upgrade to a dual speed pump. However, they could save $316 per year if they opted for a variable speed pool pump.
What to consider
A variable speed pool pump can generate bigger savings, but will cost more for the initial investment. 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 to be had by running the pump at night versus the day.
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.
