For existing pools, there are a number of energy-efficient options
that we offer. The first and the biggest is changing your pump from a single speed to either a two or variable speed. The biggest savings would be to use a variable-speed pump. Most one- and two-speed pumps are only 60 percent efficient, whereas the variable-speed pumps we install are 90 percent efficient and can typically cut energy use by 30 percent to 90 percent. GRU customers can receive a rebate for switching to a variable-speed pump.
Replacing your standard pool light with an LED light can save 90% on power consumption.
